Just simplify the given equation
y = 7.2 + 4(x-2)
y = 7.2 + 4x - 8
y = 4x - 0.8

Now they want to know the answer if X = 2
y = 4(2) - 0.8
y = 8 - 0.8
y = 7.2

I need help please?!!!!!

Xelga [282]

This equation is written in slope- intercept form, or y=mx+b.

In slope intercept form, “b” is the y intercept.

Since -5 is in the place of b, -5 is the y intercept.

Hope this helps!

3x – 1 > 4x + 7<br> What’s the answer

aliya0001 [1]

Answer:

$x$

Step-by-step explanation:

So we have the inequality:

$3x-1>4x+7$

Add 1 to both sides. The left side cancels:

$3x>4x+8$

Subtract 4x from both sides. The right side cancels:

$-x>8$

Divide both sides by -1. Since we're dividing by a negative, we flip the sign:

$x$

And we're done!

Our solution is all numbers less than -8.
