-3 0 3 6
With a ratio of 2:3, there are 3 sections on this number line ( -3 to 0, 0 to 3, and 3 to 6). Where the second section is is where the ratio would fit, because section 2 of 3 is the ratio 2:3.
Answer:
C. 4x = 12
Step-by-step explanation:
You and three friends= you + 3 friends=4 people
Pizza= 12 pieces
Each person eats equal pieces of pizza
x= number of pieces each person ate
Equation
4x=12
Divide both sides by 4
x=12/4
=3
x=3
Therefore, each person ate 3 pieces of pizza each
Check:
4x=12
4(3)=12
12=12
Answer:
b=19
Step-by-step explanation:
2x(3x+5)+3(3x+5)=ax2 +bx+c
by expansion,
6x2 +10x +9x+15=6x2 +19x +15
Pick an x-value between the interval givens. I’ll choose “1”. If you sub in one for both f(x) and g(x) you get that f(1) = -1.5 and g(1) = -0.5. Now you can divide f(1) by g(1) to get average rate of change. -1.5/-0.5 = 3.
