Answer:

<em><u>The</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u>,</u></em><em><u> </u></em><em><u>q</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>16</u></em><em><u>.</u></em>

Step-by-step explanation:

1) Divide both sides by 3.

q - 7 =  \frac{27}{3}

2) Simplify 27/3 to 9.

q - 7 = 9

3) Add 7 to both sides.

q = 9 + 7

4) Simplify 9 + 7 to 16.

q = 16

Answer:

q=16

Step-by-step explanation:

To solve this problem, you'll want to start by distributing the 3 to both q and -7, which will give you 3q-21=27. Then, you should add 21 to both sides, which will get the variable alone on one side of the equation. After that step, your equation should be 3q=48. Lastly, divide both sides by 3, which will give you the answer q=16!

I really need help I would appreciate it if someone could help me
sleet_krkn [62]

Answer:

a) The vertex of the graph is (h,k) = (0, 31), b) a = -16, c) The equation of the parabola is f(t) = -16\cdot t^{2}+31.

Step-by-step explanation:

a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.

The vertex of the graph is (h,k) = (0, 31).

b) If we know that (h,k) = (0, 31), f(t) = a\cdot (t-h)^{2} + k and (t,f(t)) = (1,15), then the value of a is:

f(t) = a\cdot (t-h)^{2} + k

15 = a\cdot (1-0)^{2}+31

15 = a\cdot 1 + 31

a = 15-31

a = -16

c) The equation of the parabola is f(t) = -16\cdot t^{2}+31.

Which two inequalities to compare |-5| and 4?
lilavasa [31]

Answer:

|-5|>4

Step-by-step explanation:

Negative 5 in absolute value is 5 since any number in absolute value turns out positive or at the very least 0. 5 is greater than 4, so |-5|>4.

Which two equations represent a nonlinear function?
irina [24]

Answer:  See below.

Step-by-step explanation:

The formatting is likely incorrect for these two options:

y=(x−1)2, and  

y = ( x − − 1 ) 2

I'll assume they were meant to be:

y=(x−1)^2, and  

y = ( x + 1 )^2

In this case they would be non-linear, since y depends on the value of x^{2}

Use a "^" sign to indicate raised to a power:  x^2 means x^{2}.  

y=(x−1)2 means y = 2x - 2

y=(x−1)^2 means y = (x-1)^{2}
