These are consecutive angles meaning they have the same angle measure
so
4x + 21 = 65
subtract 21 from both sides
4x = 44
divide both sides by 4 to isolate x
x = 11

to check:
65 =?= 4x + 21
65 =?= 4(11) + 21
65 =?= 44 + 21
65 = 65

Hope this helps :)

If you are looking to x:

Since the two angles are vertical they are congruent.

65= 4x + 21

Subtract 21 from both sides.

44=4x

Divide by 4 into both sides.

11=x

I hope this helps!

Answer:

top left

Step-by-step explanation:

Consider finding points on the graph using the equation.

x = 0 : f(0) = $0.5^{0}$ + 4 = 1 + 4 = 5 ← y- intercept

Since y- intercept is 5, this excludes the lower 2 graphs, which have y- intercepts of 1

x = 1 : f(1) = $0.5^{1}$ + 4 = 0.5 + 4 = 4.5 ⇒ (1, 4.5 )

x = - 1 : f(- 1) = $0.5^{-1}$ + 4 = $\frac{1}{0.5}$ + 4 = 2 + 4 = 6 ⇒ (1, 6 )

These points lie on the top left graph

A shipping container holds 40 tissue boxes the dimensions of a tissue box are 4 inches by 6 inches by 3 inches what is the volum

Misha Larkins [42]

Answer:

The volume of shipping container is 2880 cubic inches.

Step-by-step explanation:

We are given the following in the question:

Dimensions of tissue box =

4 inches by 6 inches by 3 inches

Volume of tissue box =

$V = l \times w\times h\\V = 4\times 6\times 3\\V = 72\text{ cubic inches}$

Number of tissue box in shipping container, n = 40

Volume of shipping container =

$V = n\times \text{Volume of tissue box}\\V = 40\times 72\\V = 2880\text{ cubic inches}$

Thus, the volume of shipping container is 2880 cubic inches.

Solve for x.<br> 4x - y= -11

balandron [24]

Step-by-step explanation:

$4x - y = - 11$

$4x = - 11 + y$

$4x = y - 11$

$x = \frac{y - 11}{4}$
