OLEGan [10]

1. Zoe stacked the most brownies. She stacked 27 brownies out of the 50 brownies.

2. 15

3. 43 + 3n ≥ 70, so n ≥ 9

4. D. 58x + 13 + 58y

5. The answer would be ≤4

6. 9.94 + 10.01p ≤ 70, so p ≤ 6

7. C 40 89

8.  D. x+(x+5)=77

Hope I helped you! Please consider marking my answer the brainliest :)

Answer:

A

Step-by-step explanation:

how long is the ball in the air ?

that is the same as asking : after how many seconds will the ball hit the ground (= reach the height of 0) ?

so, that means we need to find the zero solution of h(t).

at what t is h(t) = 0 ?

when at least one of the factors is 0 :

2(-2 - 4t)(2t - 5)

we have 3 factors

2 : can never be 0.

(-2 -4t) : can only be 0 for negative t, which does not make sense in our scenario (we cannot go back in time, only forward).

(2t - 5) : is 0 when 2t = 5 or t = 2.5

so, A is the right answer.

FYI : the starting height (on the hill) is given by t = 0 :

2(-2 - 0)(0 - 5) = 2×-2×-5 = 20 ft

What is the slope of the line passing through the points (2, −5) and (4, 1)? 2 ​−4/5 ​ ​ 5/4 ​ 3
satela [25.4K]
Just use y2-y2/x2-x1

so

1+5 (because subtracting a negative is the same as adding a positive)

4-2


6/2

or 3/1 which is the same as 3

Which of the following polynomials has solution that are real numbers ?
slava [35]
I think that the only polynomial that has a solution that are real numbers is:

B) x² + 4x + 3 = 0
(x + 3) (x + 1) → x² + 1x + 3x + 3 → x² + 4x + 3

(x+3) = 0 → x = -3

(x + 1) = 0 → x = -1

Real numbers are number that are whole numbers, rational and irrational numbers, positive and negative numbers, and even zero.
