The students in Mr. Sanchez's class are converting distances measured in miles to kilometers. To estimate the number of kilomete

rs, Abby takes the number of miles, doubles it, then subtracts 20% of the result. Renato first divides the number of miles by 5, then multiplies the result by 8. Write an algebraic expression that shows the process that both students used. Abby's expression: Renato's expression:

Step-by-step explanation:

Abby’s Expression:

Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m

2m − (0.2)2m

Renato’s Expression:

Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:

8(m/5)

F(x)=x²-3x-2 then f(-1) is given by​
evablogger [386]

Answer:

f(-1) = 2

Step-by-step explanation:

To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).

f(x)=x²-3x-2 becomes

f(-1)=(-1)² - 3(-1) -2, or

f(-1) = 1 + 3 - 2, or

f(-1) = 2

HELP! I will mark BRAINLIEST please!
const2013 [10]

Answer: A

Step-by-step explanation:

In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.

As y approaches negative infinity (goes down), x approaches negative infinity (goes left).

Simplified: as the y value decreases, the x value decreases.

As y approaches infinity (goes up), x approaches infinity (goes right).

Simplified: as the y value increases, the x value increases.
