Answer:

(-3,-20)

Step-by-step explanation:

4 +8x = y ...... equation (1)

6x - y = 2 ........equation(2)

from equation 2

6x - y = 2

6x -(4+8x) =2

6x - 4 + 8x = 2

+4 +4

6x - 8x = 6

-2x=6

divide by -2

x= -3

put x in equation (1) to solve for y

4 + 8x = y

4+8(-3)=y

4-24=y

-20=y

y= -20

solution = (-3,-20)

Answer:

(1) -5

Step-by-step explanation:

Put the value where the variable is, read the graph, and do the arithmetic.

g(2) = 3f(2) -2 = 3(-1) -2

g(2) = -5

Additional comment

f(2) is the point on the graph where it is 2 units to the right of the y-axis. At that point, the graph is 1 unit below the x-axis, so f(2) = -1.

Anastasy [175]

Answer and Step-by-step explanation:

$Let's~solve~your~problem!$

Formula :

$speed=\frac{distance}{time}$

Solving for time:

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

Solving for distance:

 $Total~Distance=40 + 180 = 220$ 

Average speed:

 $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$
