Answer:

49.71 miles per hour

Step-by-step explanation:

The speed of the vehicle is at a rate of 80 kilometers per hour.

Convert km to miles.

80 kilometers = 49.7097 miles

The speed is approximately 49.71 miles per hour.

How to solve -2p^2=16p+24

frozen [14]

Add 2p² to each side of the equation. Then you have

2p² + 16p + 24 = 0 .

Before you roll up your sleeves and start working on it, you can make it
even more convenient if you divide each side by 2 . Then you have:

p² + 8p + 12 = 0 .

Now you have a nice, comfortable, familiar-looking quadratic equation.
You can either factor the left side into (p + 6) (p + 2), or, if you can't find
the factors, you can apply the quadratic formula to it.

That's how to solve it, and find its two solutions.

(TEN POINTS)

F(-1)= -3 is (-1,-3) and f(2) = 6 is (2,6) where f(x) = y
y=mx + b is the slope-intercept form whereas m equals the slope (rate of change) and b equals the y-intercept (initial amount/what y is when x is 0.)

First, we need to find the slope between the two points (-1,-3) and (2,6). To find the slope we could use one of it's formulas $\frac{y^2 - y^1}{x^2 - x^1}$ .
1. (-1,-3)
2. (2,6)
$\frac{6 - -3}{2 - -1}$ → $\frac{9}{3}$ → $\frac{3}{1}$

The slope is 3 ( $\frac{3}{1}$ ). Thusly, y = 3x + b

To find out the y-intercept, we can reverse the slope. [Note: This $\frac{3}{1}$ is in $\frac{rise}{run}$ where rise is 'y' and run is 'x'. Reversed would be $\frac{-3}{-1}$ ]. Take the second ordered pair and use our reversed slope on it until we get 0 for x.

(2, 6) ⇒ (2 - 1, 6 -3) ⇒ (1, 3) ⇒ (0,0)

Y-intercept is 0. Therefore, y= 3x + 0 [NOTE: y = f(x), so if you want it in function notation form it's just f(x) = 3x + 0.]
