Answer:
B) -19
Step-by-step explanation:
-7 + 2x = -45
+7 +7
2x = -38
/2 /2
x = -19
Answer:
Step-by-step explanation:
The position function is
and if we are looking for the time t it takes for the ball to hit the ground, we are looking for the height of the ball when it is on the ground. Of course the height of anything on the ground is 0, so if we set s(t) = 0 and solve for t, we will find our answer.
and factor that however you are currently factoring in class to get that
t = -.71428 seconds or
t = 1.42857 seconds (neither one of those is rational so they can't be expressed as fractions).
We all know that time will never be a negative value, so the time it takes this ball to hit the ground is
1.42857 seconds (round how you need to).
Answer:
The initial value is 20.
Step-by-step explanation:
The initial value just means the value that the graph begins at (or the value of the y-intercept) so the initial value would be 20. Hope this helped :)
Answer:
x = 26
Step-by-step explanation:
Start with - 9 + x = 17, or -9 + x = 17
Solve for x by isolating x on the left side. To do this, add 9 to both sides, obtaining x = 26

<u>Isosceles trapezoid</u>
- ∠R and ∠S are supplementary
- ∠S≅∠T, ∠R≅∠V
- m∠S = m∠T = 54°
- m∠R = 180° - 54° = 126°

<u>Midsegment is half the sum of the base lengths</u>
- ST = 1/2(FP + EQ)
- 3.1 = 1/2(2.7 + EQ)
- 2.7 + EQ = 6.2
- EQ = 6.2 - 2.7
- EQ = 3.5
