Find the missing value so that the line passing through the 2 points has the given slope.
(12, -12) and (7,y); slope: -3
Answer:
y = 3
Step-by-step explanation:
Calculate the slope between the 2 points using the slope formula, then equate to - 3
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (12, - 12 ) and (x₂, y₂ ) = (7, y )
m = \(\frac{y-(-12)}{7-12}\) = \(\frac{y+12}{-5}\) = - 3 ( multiply both sides by - 5 )
y + 12 = 15 ( subtract 12 from both sides )

Plot and connect the points A(4, 6), B(4, 0), C(1, -3), and D(1, 3), and find the area of the parallelogram formed.
Answer:
18 square units
Step-by-step explanation:
The parallelogram has been plotted in the attached figure
The area of a parallelogram is b x h
where b is one side and h is the vertical distance between the two bases
In the figure, we see that base = AB is parallel to the y-axis
This means the y-coordinates of A and B are the same and the distance is obtained by taking the absolute difference between the x-coordinates of A and B
b = |x1 - 2| = |6 - 0| = 6
The height h is a perpendicular line from point D(1, 3) to the base which touches the base at point E
Since this line is horizontal to the x-axis in the figure, the y coordinates of the endpoints of the line are the same i.e y1 =3 and y2 = 3
Therefore h = absolute difference between the x coordinates
= |1-4| = 3
Given b = 6, h = 3
area = 6x 3 = 18 square units

B

21
Answer:
c = 29
Step-by-step explanation:
Law of sines is given as: \( \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} \)
B = 180 - (57 + 44) = 79°
b = 41
C = 44°
c = ?
Thus:
\( \frac{b}{sin(B)} = \frac{c}{sin(C)} \)
Substitute
\( \frac{41}{sin(79)} = \frac{c}{sin(44)} \)
Multiply both sides by sin 44
\( \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) \)
\( \frac{41*sin(44)}{sin(79)}*sin(44) = c \)
c = 29.0140633 ≈ 29

On the coordinate plane, the endpoints of a line segment are (9, 5) and (3, 7). What is the midpoint of the line segment?
Answer:
(6, 6)
Step-by-step explanation:
The formula to find midpoint is (xm, ym) = (x1+x2)/2, (y1+y2)/2
In this case, x1= 9
x2= 3
y1= 5
and y2= 7
so, (xm, ym) = (9+3)/2, (5+7)/2
which can be simplified to
(xm, ym)= 12/2, 12/2
which equals (xm, ym) = 6,6
so the x value of the midpoint is 6 and the y value of the midpoint is 6
which makes the midpoint (6,6)
Calculate the percent change. Then, describe
the change as an increase or decrease.
20 to 14
The percentage change from 20 to 14 is 30% decrease
How to determine the percentage changeFrom the question, we have the following parameters that can be used in our computation:
20 to 14
The final value (14) is less than the initial value (20)
So, the change is a percentage decrease
The change is then calculated as
Change = (Final value - Initial value)/Initial value * 100%
Substitute the known values in the above equation, so, we have the following representation
Change = (14 - 20)/20 * 100%
Evaluate
Change = -30%
Hence, the percentage decrease is 30%

Round your answer to the nearest thousandth, and only include the numerical value in your answer - do not write cscθ= in your response.
Using a calculator, the value of csc (203°) is -1.086
How to compute csc (203°) using a calculator?Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.
Since csc (203°) = 1/[sin (203°)]
Press 1/ [sin (203°)] and then the equal to button on your calculator. We have:
1/[sin (203°)] = -1.086
Note: If you calculator have "cosec" or "csc" button, you can simply press cosec (203°) or csc (203°) to get the answer.
Thus, the value of csc (203°) is -1.086

if angle 4 equals 50 degrees find the measure of angle 5 will mark brainiest
Answer:

its alternate internal angles:
∠4 ≅ ∠5 (angle 4 is congruent or equal to alternate internal angle)
therefore,
∠5 = 50°
The measure of angle 5 should be considered as the 50 degrees when angle 4 should be equivalent to 50 degrees.
What is alternate internal angles?Alternate interior angles should be created via intersecting the 2 parallel lines in a transversal way. It should be located that lies between the two parallel lines.

8. A fee-based loan is one type of loan that you may encounter. Many payday/title businesses and pawn shops charge you a set fee for borrowing money from them. This fee can make it difficult to know what interest rate you are really paying.
Lucille takes her car to a title loan business to borrow some money. She is given $1500. She must pay $300 in addition to the $1500 from the loan in 6 months.
What simple interest rate is she being charged?
The simple interest rate Lucille is being charged for taking her car to a title loan business to borrow $1,500 and repaying $300 in addition to the $1,500 from the loan in 6 months is 40%.
How the simple interest rate is computed:Simple interest refers to an interest system that does not computed interest on accumulated interest but only on the principal for each interest period.
It is the opposite of the compound interest system that computes interest on both the principal and accumulated interest for each period.
The formula for computing the simple interest rate is as follows:
Simple Interest Rate = (SI x 100)/PT
Where:
SI = simple interest
P = principal
T = Time
The principal loan = $1,500
The amount in simple interest paid = $300
The total amount repaid for the loan = $1,800 ($1,500 + $300)
The loan period = 6 months
Simple interest rate = (Simple interest x 100)/(Principal x Time)
= ($300 x 100)/$1,500 x 6/12)
= ($300 x 100 x 12)/$1,500 x 6)
= 40%

Find the equation of the line:
a) with a gradient of ½ and a y-intercept of -2
b) with a gradient of 3 and passing through the point (-2:2)
c) passing through the points (1; -2) and (-2; 1)
d) parallel to the y-axis cutting the x-axis at -1
Step-by-step explanation:
gradient means slope.
the slope is anyways the factor a of x on the slope-intercept form
y = ax + b
and in the point-slope form
y - y1 = a(x - x1)
"a" is as mentioned the slope. b is the y-intercept (the y- value when x = 0).
(x1, y1) is a point on the line.
a)
y = (1/2)×x - 2
b)
y - 2 = 3(x - -2) = 3(x + 2) = 3x + 6
y = 3x + 8
c)
remember, the slope is defined as ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
so, let's go from (1, -2) to (-2, 1)
x changes by -3 (from 1 to -2)
y charges by +3 (from -2 to 1)
the slope is +3/-3 = -1/1 = -1
so, we pick one point, e.g. (1, -2), and the line is
y - -2 = -(x - 1) = -x + 1
y + 2 = -x + 1
y = -x - 1
d)
x = -1
this is a vertical line (parallel to the y-axis) representing all points on the grid for which x = -1.
the slope is undefined, as it is y/0 (because x never changes at all). and there is no y-intercept, as x can never be 0, and the line is parallel to the y-axis, so, there cannot be any intersection point.
Answer:
\(\textsf{a) \quad $y=\dfrac{1}{2}x-2$}\)
\(\textsf{b) \quad $y=3x+8$}\)
\(\textsf{c) \quad $y=-x-1$}\)
\(\textsf{d) \quad $x=-1$}\)
Step-by-step explanation:
Part (a)Slope-intercept form of a linear equation:
\(y=mx+b\)
where:
m is the slope.b is the y-intercept.Given values:
Slope = ¹/₂y-intercept = -2Substitute the given values into the formula to create the equation of the line:
\(\implies y=\dfrac{1}{2}x-2\)
---------------------------------------------------------------------------
Part (b)Point-slope form of a linear equation:
\(y-y_1=m(x-x_1)\)
where:
m is the slope.(x₁, y₁) is a point on the line.Given:
Slope = 3(x₁, y₁) = (-2, 2)Substitute the given values into the formula to create the equation of the line:
\(\implies y-2=3(x-(-2))\)
\(\implies y-2=3(x+2)\)
\(\implies y-2=3x+6\)
\(\implies y=3x+8\)
---------------------------------------------------------------------------
Part (c)Slope formula:
\(\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}\)
where (x₁, y₁) and (x₂, y₂) are points on the line.
Given points:
(x₁, y₁) = (1, -2)(x₂, y₂) = (-2, 1)Substitute the points into the slope formula to calculate the slope of the line:
\(\implies m=\dfrac{1-(-2)}{-2-1}=\dfrac{3}{-3}=-1\)
Substitute the found slope and one of the points into the point-slope formula to create the equation of the line:
\(\implies y-y_1=m(x-x_1)\)
\(\implies y-(-2)=-1(x-1)\)
\(\implies y+2=-x+1\)
\(\implies y=-x-1\)
---------------------------------------------------------------------------
Part (d)If the line is parallel to the y-axis, it is a vertical line.
The equation of a vertical line is x = c.
Therefore, as the line intersects the x-axis at -1, the equation of the line is:
\(\implies x=-1\)
