Answer:

m<wzx = 71

Step-by-step explanation:

Assuming these are interior angles of a triangle.

The sum of all three interior angles of a triangle is always 180 degrees, therefore:

m<xyz + m<wxz + m<wzx = 180

Substitute our values:

58 + 51 + m<wzx = 180

m<wzx = 180 - 58 - 51

m<wzx = 71

Answer:

We can use the equation for the velocity of an object under free fall:

v^2 = u^2 + 2as

v = final velocity (what we want to find)

u = initial velocity (zero in this case)

a = acceleration due to gravity (9.8 m/s^2)

s = distance (75 m)

Plugging in the values, we get:

Therefore, the velocity of the 2 kg ball just before it hits the ground is approximately 38.3 m/s.

This calculation assumes that there is no air resistance, which is an idealized scenario. In reality, air resistance would slow down the ball and cause it to hit the ground with a lower velocity.

Answer: A proper subset is a subset that is not identical to the original set—it contains fewer elements. You can see that there are 16 subsets, 15 of which are proper subsets. Listing the sets is fine if you have only a few elements.

we know that $1290 is to be divided on a 7:8 ratio, so we'll start off by dividing 1290 by (7+8) and give each person accordingly

\(1290~~ at~~ 7:8\implies 7\cdot \cfrac{1290}{7+8}~~ :~~8\cdot \cfrac{1290}{7+8} \\\\\\ 7\cdot 86~~:~~8\cdot 86\implies 602~~ :~~688\)

Answer:

The width is 8

Step-by-step explanation:

if the ratio of length to width is 9 to 4. and we know the length is 18, 18 is 2 times as much as 9, so 4*2=8.                   9*2=18,4*2=8

The expression for the total cost of Sal's purchases is 7x + 5y cents.

We know that Sal paid (x + 2y) cents for a quart of milk and (2x + y) cents each for three cartons of orange juice.To find the total cost of Sal's purchases we need to add the cost of the milk and the cost of the three cartons of orange juice and simplify the expression.The cost of the milk is given as (x + 2y) cents. The cost of three cartons of orange juice is (2x + y) cents each.

Therefore, the cost of three cartons of orange juice is (3 × (2x + y)) cents. To find the total cost of Sal's purchases, we add the cost of the milk and the cost of the three cartons of orange juice.(x + 2y) + (3 × (2x + y)) cents = x + 2y + 6x + 3y cents= 7x + 5y cents.

Answer:

f(g(-1)) = 22

g(f(-1))=6

Step-by-step explanation:

We are given

\(f(x)=5x+2 \\g(x)=3-x\)

We need to find f(g(-1)) and g(f(-1))

Finding f(g(-1))

First we will find f(g(x)) i.e

\(f(g(x))=5(3-x)+2\\f(g(x))=15-5x+2\\f(g(x))=-5x+17\)

Now finding f(g(-1)) by putting x=-1

\(f(g(x))=-5x+17\\Put \ x=-1\\f(g(-1))=-5(-1)+17\\f(g(-1))=5+17\\f(g(-1))=22\)

So, f(g(-1)) = 22

Finding g(f(-1))

First we will find g(f(x)) i.e

\(g(f(x))=3-(5x+2)\\g(f(x))=3-5x-2\\g(f(x))=-5x+1\)

Now finding g(f(-1)) by putting x=-1

\(g(f(x))=-5x+1\\Put \ x = -1\\g(f(-1))=-5(-1)+1\\g(f(-1))=5+1\\g(f(-1))=6\)

So, g(f(-1))=6

The system of inequalities that is graphed is:

y ≤ - (2/3)*x

y < x - 3

So the correct option is B.

First, we can see that for both of the inequalities the shaded part is below the lines.

You also can see that the solid line (correspondent to the symbol ≤) is the one with a negative slope, and the dashed line (correspondent with the line <) is the one with a positive slope.

Only with that, we conclude that the correct option is B.

The measure of the angles for the similar triangles are ∠G = 105°; ∠H = 55° and ∠I = 20°

Two triangles are said to be similar if the ration of their corresponding sides are in the same proportion. Also, all their corresponding angles are congruent with each other.

From the diagram shown:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)

20 + 105 + ∠Z = 180

∠Z = 55°

Since triangle XYZ and triangle GHI are similar, hence:

∠X = ∠G = 105°; ∠Z = ∠H = 55° and ∠Y = ∠I = 20°

The measure of the angles are ∠G = 105°; ∠H = 55° and ∠I = 20°

Step-by-step explanation:

Simplifying this equation, we get:

8k + 14 = 30

8k = 16

k = 2

Therefore, the value of k is 1.

In mathematics, a polynomial is an expression consisting of variables (usually represented by x), coefficients, and non-negative integer exponents, which are combined using the operations of addition, subtraction, and multiplication. For example,

\(3x^2 + 2x - 1\)

is a polynomial with three terms, or a "trinomial," where the variable x is raised to the powers of 2 and 1, and the coefficients are 3, 2, and -1.

The degree of a polynomial is the highest power of the variable in the expression. For example, the polynomial above has a degree of 2, since the highest power of x is 2.

Polynomials are used in many areas of mathematics, including algebra, calculus, and geometry, and are used to model many real-world phenomena.

We can use the remainder theorem, which states that if a polynomial f(x) is divided by (x - a), then the remainder is equal to f(a). In this case, we know that when the polynomial\(l x^3 + kx^2 + 2kx\) + 6 is divided by (x - 2), the remainder is 30. So, we can set up the following equation:

\(x^3 + kx^2 + 2kx + 6 = (x - 2)q(x) + 30\)

where q(x) is the quotient when. \(x^3 + kx^2 + 2kx + 6\) is divided by (x - 2). We don't need to know what q(x) is, since we're only interested in finding k.

Now, let's substitute x = 2 into the equation above:

\(2^3 + k(2^2) + 2k(2) + 6 = (2 - 2)q(2) + 30\)

Simplifying the left-hand side, we get:

\(8 + 4k + 4k + 6 = 30\)

\(16k = 16\)

\(k = 1\)

OR

8 + 4k + 4k + 6 = 30

8k + 14 = 30

8k = 16

k = 2

Step-by-step explanation:

If you are trying to find y=mx+b, the y is the variable m is the slope and x is also the variable and +b is the y interecept and IT describes where the line crosses the y axis. Starting you will write y= m the slope and to find that u have to do rise/run in this can you rise down 3 and run 2 and u divide that and get 1.5. So far you far u have y=1.5x+. Where does the line cross the y axis? IT is on the 3 becuase the y axis goes up and down and the x axis goes left and right. The line crossed the 3 on the y axis so "b" is 3. The full equation is

Y=1.5x+3.

step two: find common denominator which is 10

step three convert to common denominator, 9/5=45/10 and 7/5= 14/10

step four add together which is 59/10

step five simplify into mixed number 5 9/10

Answer:

\(5 \frac{9}{10}\) = 5 9/10

Step-by-step explanation:

Rewrite by seperating

\(4 + \frac{1}{2} + 1 + \frac{2}{5}\)

Combine the whole numbers '4' and '1'

\(5 + \frac{1}{2} + \frac{2}{5}\)

Now add the both fractions

\(\frac{1}{2} + \frac{2}{5}\) ; fractions should have a common denominator in order to be added

The common LCD is 10

\(\frac{1}{2} * \frac{5}{5} + \frac{2}{5}*\frac{2}{2}\)

\(\frac{5}{10} + \frac{4}{10}\) now we can add

\(\frac{5}{10} + \frac{4}{10} = \frac{9}{10}\)

Lastly combine the whole number part and the fraction part

\(5 + \frac{9}{10}\) = \(5 \frac{9}{10}\)

x = - 9

Step-by-step explanation:

2x + 7 = - 11 ( subtract 7 from both sides )

2x = - 18 ( divide both sides by 2 )

x = - 9

The answer is:

x = -9

Work/explanation:

The point of equations is to find the variable's value by isolating it step-by-step.

For this equation, the variable is x.

To isolate it, I will perform a few operations.

First, I will subtract 7 from each side:

\(\sf{2x+7=-11}\)

\(\sf{2x=-11-7}\)

\(\sf{2x=-18}\)

Divide each side by 2

\(\sf{x=-9}\)

Hence, x = -9.
