Answer:

its a or y = -3/4x -3

Step-by-step explanation:

slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. the line intercepts at the y at point -3 so the y-intercept is -3 the slope is -3/4 and you just plug them into the slope intercept form

If an object is dropped from a height of 55 feet, the function d = -16^2 + 55 gives the height of the object after t seconds. Gr

Answer:

Approximately 1.9 seconds (correct to nearest tenth)

Step-by-step explanation:

Looks like the function is d = -16t^2 + 55 ( you left out the t)

The answer is the value of t when d = 0 so we have the equation:-

0 = -16t^2 + 55

16t^2 = 55

t^2 = 55/16

t = sqrt (55/16)

= 1.85 seconds

3/9 + 3/27 = ? Adding fractions

RideAnS [48]

$\frac{3}{9}$ + $\frac{3}{27}$ equals $\frac{4}{9}$ .

First, simplify $\frac{3}{9}$ to $\frac{1}{3}$ and also $\frac{3}{27}$ to $\frac{1}{9}$ . Your problem should look like: $\frac{1}{3}$ + $\frac{1}{9}$ .
Second, find the least common denominator of $\frac{1}{3}$ and $\frac{1}{9}$ to get 9.
Third, make the denominators the same as the least common denominator (LCD). Your problem should look like: $\frac{1x3}{3x3}$ + $\frac{1}{9}$ .
Fourth, simplify to get the denominators the same. Your problem should look like: $\frac{3}{9}$ + $\frac{1}{9}$ .
Fifth, join the denominators. Your problem should look like: $\frac{3+1}{9}$ .
Sixth, simplify. Your problem should look like: $\frac{4}{9}$ , which is the answer.
