Answer:

The point (0,4) doesn't make either equation true.

Step-by-step explanation:

Consider the equations.

y=-2x and y=x+3

We need to determine the point (0,4) make either equation true.

Substitute x=0 and y=4 in y=-2x

4=-2(0)

4=0

Which is false.

Substitute x=0 and y=4 in y=x+3

4=(0)+3

4=3

Which is false.

Hence, the point (0,4) doesn't make either equation true.

Kristen spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. If she bought a total of 7 then how many of each
Sloan [31]
<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations

-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>

Write the equation of the line f.
vekshin1

Answer:

y = -4

Step-by-step explanation:

This is because any point on that line would have a y coordinate of -4 → e.g. (6, -4), (-2, -4), and it intercepts the y axis at -4.

Hope this helps!

HURRY ILL GIVE BRAINLIEST!!!
Free_Kalibri [48]

ANSWER

D) (a + 1, b + m)

EXPLANATION

The given line passes through (a,b) and has slope m.

The equation is:

y  - b = m(x - a)

When x=a+1, we obtain

y  - b = m(a + 1 - a)

This

y  = m( 1 ) + b

y = m + b

Therefore,(a + 1, b + m) must also lie on this line.

The correct answer is D.
