Answer:

x = 8

Step-by-step explanation:

3/4x + 5 = 11

3/4x = 6

12/4 = 3x = 24

3x = 24

x = 8

Answer:

x = 8

Step-by-step explanation:

$\frac{3}{4}$ x + 5 = 11

$\frac{3}{4}$ x = 6

x = $\frac{4}{3}$ (6)

x = 8

WARRIOR [948]

Answer:

A. Find h(10) = 0 . . . (it is not)

B. h(5.235) = 0; hang time was about 5.235 seconds

Step-by-step explanation:

The hang time of the ball is the value of x in h(x) such that h(x) = 0.

Juan can show the hang time is 10 seconds by finding h(10) = 0. The value of h(10) is ...

h(10) = -16(10²) +83(10) +4 = -1600 +834 = -766 ≠ 0

Juan cannot prove the hang time was 10 seconds.

The hang time is the solution to ...

h(x) = 0

-16x² +83x +4 = 0 . . . . . use the given expression for h(x)

x² -5.1875x = 0.25 . . . . divide by -16

x² -5.1875x +6.7275390625 = 6.9775390625 . . . . add (5.1875/2)²

(x -2.59375)² = 6.9775390625 . . . . . . . . . . rewrite as a square

x = 2.59375 ±√6.9775390625 ≈ {-0.048, 5.235} . . . . square root, find x

The hang time of the ball was about 5.235 seconds.

We like a graphing calculator for finding a quick solution to questions like this.

posledela

Answer:

1.5seconds

Step-by-step explanation:

When the ball hits the ground, the height is equal to zero. So find t when H=0:

H=16t²+8t+80

0=16t²+8t+80

0=2t²+t+10

0=(2t-3)(t+2)

So (2t-3)=0, or (t+2)=0

So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds

Find the difference.<br>(2n - 9) - 5(-2.4n + 4) =

MArishka [77]

Answer:

14n - 29

Step-by-step explanation:

First you'd distribute in the parentheses by -5. -5 × -2.4n and -5 × 4 which you would get 12 and -20.

Then, bring everything down and combine like terms. 2n + 12n = 14n || -9 - 20 or -9 - (-20) = -29. 14n - 29 is the lowest you can simplify because you can subtract a variable and a constant together.
