Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: N + 9
N is equal to 12 in this equation
12 + 9 is 21.
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is 12(12)= 144
Hope this helps!
(By the way, I'm horrible at math so this could be completely wrong)

graph the equation y = 1/2x-2 using 2 slope and y-intercept
for graph this equation,
we will calculate the point on this line,
the equation is
y = 1/2x-2
when x = 0
y = 1/2 (0) - 2
y = -2
thus, the point is (0, -2)
when x = 2
y = 1/2 (2) - 2
y = 1 - 2
y = -1
thus, the point is (2, -1)
when x = 4
y = 1/2(4) - 2
y = 2 - 2
y = 0
thus, the point is , (4, 0)
so we mark these points on the graph and join them to get a line on the graph.
Two friends, Emma and Alice, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Emma's hair is already 10 centimeters long and grows at a constant rate of 2 centimeters per month. Alice's hair is 30 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be?
Answer:
50 cm
Step-by-step explanation:
Let
x = number of months
Emma = 10 + 2x
Alice = 30 + x
Equate the equation of both girls
10 + 2x = 30 + x
10 - 30 = x - 2x
-20 = - x
x = 20
How long will their hair be?
Emma = 10 + 2x
= 10 + 2(20)
= 10 + 40
= 50cm
Alice = 30 + x
= 30 + 20
= 50 cm

Which of the following types of radiation has a positive charge?
A)X
B)Gamma
C)Cathode
D)Alpha
E)Beta
Alpha particle radiation is the type of radiation that has a positive charge. Alpha radiation is a type of ionizing radiation that includes alpha particles. Alpha particles are made up of two protons and two neutrons, similar to the nucleus of a helium atom.
Alpha radiation can be stopped or absorbed by a piece of paper or the outer layer of human skin since it only travels a short distance through the air. Alpha radiation is not as penetrating as beta or gamma radiation because of its mass. They have a positive charge due to the two protons present in their nucleus. When alpha particles collide with matter, they lose their energy quickly. They produce heavy damage over a small distance, which can cause damage to internal organs if inhaled or ingested.
Cathode rays, also known as cathode ray tubes (CRT), were the first positive identification of electrons. When high-voltage electricity is applied to electrodes in a vacuum tube, the cathode emits rays, which are negatively charged particles that travel toward the positively charged anode. The cathode is negatively charged, which is why cathode rays are negatively charged.
Beta radiation is composed of high-speed electrons or positrons, and they have a negative charge. They have greater penetrative power than alpha radiation, but they are more easily absorbed by materials like aluminum. When a beta particle collides with matter, it produces less ionization than an alpha particle. However, beta particles have more range and cause more serious skin burns. They are produced in the decay of heavy isotopes like uranium and plutonium.

The number of triangles which can be formed from two given angle measures and the length of their included side is one which is option (b).
A triangle is a polygon with three sides and three corners. The angle formed within the triangle is 180 degrees. This means that the sum of the interior angles of a triangle is 180°. The polygon with the fewest number of sides. Thus, a triangle is defined as a three-sided two-dimensional figure with interior angles equal to 180°.Since two angles have already been given, the value of the third angle is already fixed. So the third angle is the difference between 180 and the sum of the two angles. Given an angle, any number of angles can be formed as long as the angular relationship is consistent.
However, the number of triangles that can be formed is limited to one, since the length scale of one of the sides is already given. You cannot simply specify the scale of the two sides . The other two side measurements are calculated using the triangle formula.

Prove AB is congruent to BC given BE bisects DBC and BE is parallel to AC
AB is congruent to BC given BE bisects DBC and BE is parallel to AC is proved .
What is congruent ?
Congruent refers to having the same shape and size. In mathematics, two objects are said to be congruent if they are identical in shape and size, and can be superimposed onto one another. The symbol used to represent congruence is ≅. Congruence applies to various geometric objects, such as triangles, rectangles, circles, and more. When two objects are congruent, they have all corresponding angles equal and all corresponding sides equal in length.
Step 1: Statement: \($\angle DBE = \angle EBC$\)
Reason: Given that overline BE bisects \($\angle DBC$\)
Step 2: Statement: \($\angle DBC + \angle EBC = 180^\circ$\)
Reason: Angle sum property of a straight line.
Step 3: Statement: \($\angle ABC + \angle EBC = 180^\circ$\)
Reason: Angles on a straight line sum to \(180^\circ$, and $\overline{BE} || \overline{AC}$\) implies that \(\angle ABC$ and $\angle EBC$\) are co-interior angles.
Step 4: Statement: \($\angle ABC = \angle DBC$\)
Reason: From step 2 and step 3, \($\angle ABC + \angle EBC = \angle DBC + \angle EBC = 180^\circ$\). Thus, \($\angle ABC = \angle DBC$\).
Step 5: Statement: \($\triangle ABE \cong \triangle CBE$\)
Reason: By the angle-angle-side congruence criterion, since \($\angle DBE = \angle EBC$\) (from step 1) and \($\angle ABC = \angle DBC$\) (from step 4), and \($\overline{BE}$\) is common to both triangles.
Step 6: Statement: \($AB = BC$\)
Reason: By step 5, \($\triangle ABE \cong \triangle CBE$\), so corresponding sides are congruent, including \($\overline{AB} \cong \overline{BC}$\).
Therefore, AB is congruent to BC given BE bisects DBC and BE is parallel to AC is proved .

A local farmer plants a given number carrots on a certain number of days. We are looking at the number of carrots the farmer can plant over two days. Suppose that the famers must plant at least 4 carrots on the first day, no more than 9 carrots on the second day and farmer has to plant more carrots on the second day than the first day. a) Determine the sample space of the experiment. b) If each of the outcomes in (a) have equal probability of occurring find the probability of the following events: i. ii. Event that there were 13 carrots in total planted over the two days. Event that an odd number of carrots were planted on the second day. c) Are the events (i) and (ii) mutually exclusive? Motivate your answer! d) Are the events (i) and (ii) statistically independent? Motivate your answer!
The sample space of the experiment is {(4,5),(4,6),(4,7),(4,8),(4,9),(5,6),(5,7),(5,8),(5,9),(6,7),(6,8),(6,9),(7,8),(7,9),(8,9)}. The probability that there were 13 carrots in total planted over the two days is 0.4 and the probability that an odd number of carrots were planted on the second day is 0.4.
a) Sample space: {(4,5),(4,6),(4,7),(4,8),(4,9),(5,6),(5,7),(5,8),(5,9),(6,7),(6,8),(6,9),(7,8),(7,9),(8,9)}
b) i). There are 6 ways of planting 13 carrots, and there are 15 possible outcomes for planting carrots. Hence,
P(13) = 6/15
P(13) = 0.4
ii). We can have odd total carrots only if we have an odd number of carrots planted on both days or we plant 5 carrots on the first day and 7 carrots on the second day. Therefore, the sample space is {(4,5),(6,5),(4,7),(6,7),(5,5),(5,7)}. There are 6 possible outcomes for planting an odd number of carrots. Hence,
P(odd) = 6/15
P(odd) = 0.4
c) The events are mutually exclusive because if an odd number of carrots are planted on the second day then the total number of carrots planted cannot be 13.
d) We know P(13) = 0.4 and P(odd) = 0.4, and P(13 and odd) = 0, so the events are not statistically independent.

What is Systems of Linear Equations?
A direct equation is an equation in two variables, and when it's graphed, a straight line is formed. The line is created by the combination of corresponding values that satisfy the equation. utmost generally, direct equations use the variables x and y so the corresponding values can be colluded as (x,y) pairs on the co-ordinate plane .
Main body:
A system of direct equations is a group of two or further direct equations. The result to any system of direct equations is the point where the lines cross on a graph, still, because lines can be resemblant or coinciding, it's possible for a system to have no result( parallel) or infinitely numerous results( coinciding).
y = 3x−4
y=−x/2−4
now solve:
3x=−3/2x
