Answer: B) increasing for x < -4/3 and x > 4/3
decreasing for -4/3 < x < 4/3
<u>Step-by-step explanation:</u>
Graph the equation and follow the curve from left to right. If you are going up, it is increasing. If you are going down, it is decreasing.
Refer to the image below. Red is increasing. Blue is decreasing.
The vertices are at: x = -4/3 and x = 4/3
Answer:
Step-by-step explanation:
y = 2x + 30
y = 2(5) + 30
y = 10 + 30
y = 40
answer is a
Answer:
x = -4/3
Step-by-step explanation:
6x + 11 = -6x - 5
12x = -16
x = -4/3
The equation for the line of reflection that maps the shape to itself is y = 2
Answer
A. y = 2
We know that 8/75 patients prefer bubblegum toothpaste. We want to make the ratio, “_:1500”. To do this, we divide 1500 by 75 to get 20. The ratio is now p : 1500. Now, we must do the same thing on both ends: since 75 times 20 got us 1500, 8 times 20 gets us 160. So, 160 out of the dentist’s 1,500 patients prefer bubblegum toothpaste.
