Answer:

x= -1

Step-by-step explanation:

since y is -5 then we would put that in the second equation:

2x - 4(-5) = 18

then it’s:

2x + 20 = 18

Then we subtract 20 from both sides

2x = -2

Last we divide both by 2 and we get x = -1

Which of the following equations is modeled by the graph.
Sergio [31]

Answer:

a = 50t

Step-by-step explanation:

The graph goes through (0,0) so the y intercept is 0

a=5t

a=50t

a=50 + t    not it

a=10t ​

The slope is  y/x since the y intercept is 0

m = 50/1 = 50

The equation for the line is

y = 50x+0

y = 50x

Using the variables given

a = 50t

NeX [460]
1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or 8:32.

2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x = 52 [tex] \frac{miles}{hour} [tex]

3) Which typing time is fastest? I answered this earlier, refer to it please refer to it: brainly.com/question/2560190
