Answer:

Statement 4 in true.

Step-by-step explanation:

1. f(-2)=(-3*(-2)+2)^2+(-2)=(6+2)^2+(-2)=8^2-2=62, FALSE

2. f(-5)=(-3*(-5)+2)^2+(-5)=(15+2)^2+(-5)=17^2+(-5)=289-5=284, FALSE

3. f(3)=(-3*3+2)^2+3=(-9+2)^2+3=(-7)^2+3=49+3=52, FALSE

4. f(5)=(-3*5+2)^2+5=(-15+2)^2+5=(-13)^2+5=169+5=174, TRUE

Answer:

option 4

Step-by-step explanation:

f(- 2) = (6 + 2)² - 2 = 8² - 2 = 64-2 = 62 ≠ 64

f(- 5) = (15 + 2)² - 5 = 17² - 5 = 289 - 5 = 284 ≠ 29

f(3) = (- 9 + 2)² + 3 = (- 7)² + 3 = 49 + 3 = 52 ≠ - 11

f(5) = (- 15 + 2)² + 5 = (- 13)² + 5 = 169 + 5 = 174 ← True

The treatment group using Spray A reported a mean of 3.5 mosquito bites.

The treatment group using Spray B reported a mean of 5.6 mosquito bites.

After the data are  re-randomized; the differences of the means are shown in the dot plot. The dot plot is attached in the file below;

The best conclusion that can be make based on the data from the dot plot is :

What do you do first to graph the equation? 3x - 2y = 8​
kolezko [41]

Answer:

Figure out the x and y intercepts.

Step-by-step explanation:

you should find what the y or x intercept's are.

To figure that out you need to divide the number next to x or y to 8. use x to find out x intercept and y for y intercept.

lets find out y intercept

8 / -2 = -4

and now x intercept

8 / 3 = 1.75 or 1 (3/4)

Once you found out the intercepts you can now graph the equation.
