<h3>
Answer: D. x = 4</h3>
===============================================
Explanation:
First compute f(2)
f(x) = 3x-1
f(2) = 3(2) - 1 ... replace every x with 2; use PEMDAS to simplify
f(2) = 6 - 1
f(2) = 5
When we say g(x) = f(2), we really mean g(x) = 5
g(x) = 2x-3
2x-3 = g(x)
2x-3 = 5 .... plug in g(x) = 5
2x-3+3 = 5+3 ... add 3 to both sides
2x = 8
2x/2 = 8/2 ... dividing both sides by 2
x = 4
Answer:
equals -43
Step-by-step explanation:
Z = ax / y
A = 2
X = 28
Y = 14
Plug it into the formula then solve for Z.
Z = ax / y
Z = 2(28) / 14
Z = 56 / 14
Z = 4
Therefore, she should buy 4 boxes.
Answer:
n = 9.
Step-by-step explanation:
There are 9 0's after the 3 so it's
3 x 10^9.
Answer:

Step-by-step explanation:
Alternating angels are equal if 3 is equal to 40 then 7 must also be forty (this only applies since the lines are parallel)
