Answer:

See below!

Step-by-step explanation:

1. 5g + h = g

4g = -h

g = $-\frac{h}{4}$

2. y = mx + b

y - b = mx

m = $\frac{y - b}{x}$

3. 3y + z = am - 4y

7y = am - z

y = $\frac{am - z}{7}$

4. km + 5x = 6y

km = 6y - 5x

m = $\frac{6y - 5x}{k}$

5. $\frac{3ax - n}{5} = -4$

3ax - n = -20

3ax = n - 20

x = $\frac{n-20}{3a}$

6. $\frac{by+2}{3}= c$

by + 2 = 3c

by = 3c - 2

y = $\frac{3c-2}{b}$

7. at + b = ar - c

at - ar = -b - c

a(t - r) = -(b + c)

a = $-\frac{b+c}{t-r}$

tiny-mole [99]

Answer: The campers will be $40\ miles$ from their car after 12 hours.

Step-by-step explanation:

<h3> The missing graph is attached.</h3>

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choosing the points (0,4) and (2,10), we get:

$m=\frac{4-10}{0-2}=3$

We can susbstitute the point (0,4) and the slope into $y=mx+b$ and solve for "b":

$4=3(0)+b\\\\b=4$

Then, the equation of this line is:

$y=3x+4$

Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:

$d=3h+4$

Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute $h=12$ into the equation and evaluate. Then we get:

$d=3(12)+4\\\\d=40$

Nataly [62]

explanation: When you say rose that means the temp got hotter right? If so then at midnight it was -28 degrees Celsius and it rose 8 degrees to -20 degrees Celsius at 6:00am.

Y= x^2 + 2x + 7 in vertex form

Maslowich

Answer:

( 1, 6 )

Step-by-step explanation:

y = (x − 1 ) 2 + 6

Use the vertex form, y = a ( x − h ) 2 + k , to determine the values of a , h , and k . a = 1 h = 1 k = 6

Find the vertex ( h , k ) . ( 1 , 6)
