Question

HELP ME PLEASEEEE! Thank you

Answer 1

Answer:

A. Yes

B. Yes

C. No

Step-by-step explanation:

We can substitute each value in to the equation and see if the sides match up. Let's start with a.

$4\cdot(2)-3 = -2\cdot(2)+9\\8-3 = -4+9\\5 = 5$

So, n = 2 works for equation a. Let's try B.

$9\cdot(\frac{10}{3}) - 19 = 3\cdot(\frac{10}{3}) + 1\\\\\\\frac{90}{3} -19 = \frac{30}{3} + 1 \\ 30 - 19 = 10 + 1\\11 = 11$

So, m = $\frac{10}{3}$ works for B. Now let's try C.

$3(30+8) = 2\cdot(30)-6\\3(38) = 60-6\\114 \neq 54$

So y = 30 doesn't work for C.

Hope this helped!
