Again, Jjmarie, please do not ask questions about equations in this format. Your job is to SOLVE <span>3(13-2a)=-3+a, not to find out "what it equals."

"Solve" means "find the value of a that satisfies the given equation."

</span><span>3(13-2a)=-3+a, when multiplied out, is 39 - 6a = -3 + a

Combining like terms: -7a = -42, or a = 6. See? a equals 6; the equation does not equal 6. You could say, however, that "</span><span>3(13-2a)=-3+a" is TRUE when a = 6. It's a conditional statement.</span>

please help 30 points !! in a proportional relationship when Y=2 when X=8 Which of the following equations would describe this r

Alex777 [14]

Answer:

(1)

Step-by-step explanation:

We will try:

(1) y = $\frac{1}{4}$ x => 2 = 2 (seems legit)

(2) y = 4x => 2 = 32 (nope)

(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)

(4) y = $\frac{1}{2}$ x - 2 => 2 = 2 (like the above)

Which phrases describe the graph of f(x) = |x| ? Check all that apply.

Sav [38]

The answers are:

A) V-Shaped (because absolute value graphs are v-shaped)
C) Opens up (because the leading coefficient is positive)
F) Symmetric with respect to the y-axis (if you look at the graph y= |x|, you see that the y-axis cuts through the middle of the "v-shape", and that it is symmetric)
