10. Evaluate if: y = 4 and z = -2

Bas_tet [7]

Substitute with y = 4 and z = -2

= 4^2*(-2)/4 + 10

= 16*(-2)/4 + 10

= -32/4 + 10

= -8 + 10

= 2

Hope This Helped! Good Luck!

If m = 7x + 7, m = 4y, and m = 112, find the values of x and y

tester [92]

<span>If m = 7x + 7, m = 4y, and m = 112

since m = 112

112 = 7x + 7
112 - 7 = 7x
105= 7x
x = 15

112 = 4y
y = 28</span>

If a=(-1, -3) and b=(11, -8) what is the length of ab?

professor190 [17]

Answer: D. The length is 13 units.

Step-by-step explanation:

(-1, -3 ) Find the difference between the x values and y values.

(11, -8)

-3-(-8) = 5

-1-11 = -12 now find the absolute values.

The absolute value of 5 is 5 . The absolute value of -12 is 12.

Now use the Pythagorean Theorem formula a^2 + b^2 =c^2 where c square is the length between AB.

5^2 + 13^2 = C^2

25 + 144 = c^2

169=c^2

c= 13

Yesterday, Jack drove 43.5 miles. He used 11 gallons of gasoline. What is the unit rate for miles per gallon?

Alexxx [7]

Answer:

the unit rate for miles per gallons = $3.95 miles$

Step-by-step explanation:

Let x be the unit rate for miles per gallon.

Given:

Jack drove 43.5 miles. He used 11 gallons of gasoline.

Find the unit rate for miles per gallon?

Jack used 11 gallons of gasoline for 43.5 miles.

11 gallons = 43.5 miles

The unit rate for miles per gallon is

unit rate of gallons = total miles divided by total used gallons of gasoline

$x=\frac{43.5}{11}$

$x=3.95miles$

Therefore, the unit rate for miles per gallons is 3.95 miles.
