Answer:
Grandfather age = 20 * 4 = 80
Step-by-step explanation:
Let Elena age be x
grandfather age is 4x
x + 4x = 100
5x = 100
x = 100/5 = 20 = Elena age
Answer:
Rotate the triangle until it makes a right angle. It should be somewhere around the coordinates (2,-1)
Step-by-step explanation:
LMK if you need more help!
3 x 1.5 = 4.5 and positive, negative
We are given the function expressed as:
<span>h(t) = 300 – 16t
where h is the height of the ball in time t.
We calculate the height at time equal to 2.4 seconds as follows:
</span>h(t) = 300 – 16(2.4)
h(t) = 261.6 ft
Hope this answers the question. Have a nice day.
Answer:
m = 
Step-by-step explanation:
I'm assuming by m, you mean the slope.
You have two points. (-11, 5) and (2, -4)
- m = change in y-value ÷ change in x-value
1) Substitute in the points.
m = 
2) Solve.
So, the slope would equal
