Answer:
-2/5
Step-by-step explanation:
2x - 11 = 4x - 13 - 7x
2x - 11 = -3x - 13
2x - 11 + 3x = -13
5x - 11 = -13
5x=-13+11
5x=-2
X= - 2/5
Answer:
42
Step-by-step explanation:
Number of students whose favorite class is Math:
60*0.85=51
Number of students whose favorite class is Science:
15% is equal to 0.15.
60*0.15=9
Subtract number of students who like science from number of students who like math.
51-9=42
42 more students in the survey prefer math over science.

================================================
Work Shown:
Those steps show we start with the outer function f(x) = 5x-3. Then we replace every x with g(x) in the second step. Afterward, we plug in g(x) = 6x^2-3 and we simplify.
-----------------------
We'll follow similar steps for (g∘f)(x)
But this time we started with g(x), plug in f(x) for every x, and then simplified.
