for
x^m=y
that means
log_x(y)=m
so

7^{x+4}=-34 means

log_7(-34)=x+4
minus 4 from both sides
log_7(-34)-4=x

Xavier has $23.50 in his savings account. He deposits $35 every week. His mother also deposits $20 into the account every time
maria [59]

Answer:

Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work.  The constant is 23.50.

Part B: He will have $503.50

Part C: The coefficient would change, because the amount per car changes, not the amount of cars.

Step-by-step explanation:

A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.

We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.

1.   4 • (–3) • 5
   so 4 x (-3) = -12  and then -12 x 5 = -60
2.   (2.25 x 23) x 4
so (2.25 x 23) 51.75  and then 51.75 x4 = 207
4.  5 x 12 x (-2)
 so 5 x 12 = 60  and then 60 x (-2) = -120
5.   35(26)(0) =
  so 35 x 26 = 910  and then  910 x 0 = 0
