Answer:

A. 9 mi.

Step-by-step explanation:

Here, use the Pythagorean Theorem, but leave "a" as it is.

a² + b² = c²

a² + 12² = 15²

a² + 144 = 225

a² = 225 - 144

a² = 81

a = √81

a = 9

The missing side is 9 miles long.

Graph the equation on the coordinate plane. y = 4x+4

Alla [95]

To graph the equation of the line, find the x-intercept and the y-intercept of the function

we have

$y=4x+4$

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

Step 1

Find the x-intercept

For $y=0$

$0=4x+4$

$4x=-4$

$x=-1$

the x-intercept is the point $(-1,0)$

Step 2

Find the y-intercept

For $x=0$

$y=4*0+4$

$y=4$

the y-intercept is the point $(0,4)$

Step 3

Graph the points and draw the line

see the attached figure

therefore

the answer in the attached figure

Answer:

4 gallons

Step-by-step explanation:

We can write a ratio to solve

95 miles 76 miles

5 gallons x gallons

Using cross products

95 * x = 5 * 76

Divide each side by 95

x = 5 * 76 / 85

x =4
