Answer:
a=-5, k=31
Step-by-step explanation:
Determine a and k so the given points are on the graph of the function:
(1,11) (2,-14)
[tex]y=a(x+1)^2+k[/tex]
To find the required values, we substitute the points into the equation:
[tex]11=a(1+1)^2+k[/tex]
[tex]-14=a(2+1)^2+k[/tex]
Operating:
[tex]11=a(2)^2+k[/tex]
[tex]-14=a(3)^2+k[/tex]
Simplifying:
[tex]11=4a+k[/tex]
[tex]-14=9a+k[/tex]
Subtract the second equation from the first equation:
[tex]11+14=4a-9a[/tex]
Simplifying:
[tex]25=-5a[/tex]
Solving:
[tex]a=25/(-5)=-5[/tex]
a=-5
Use this equation to find k:
[tex]11=4a+k[/tex]
[tex]11=4(-5)+k[/tex]
[tex]11=-20+k[/tex]
k=31
a=-5, k=31
Answer:
a = -5
k = 31

The difference of twice a number and 3 is at most -21
Answers
Answer:
The equation: 2n - 3 ≤ -21
The answer to the equation: n ≤ 9
Step-by-step explanation:
How to get the equation:
The difference of symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2n - 3. The n symbolizes the number.
is at most symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.
Now are equation is 2n - 3 ≤ -21
How to solve it:
2n - 3 ≤ -21
Add 3 to both sides of the equation
2n ≤ 18
Divide both sides of the equation by 2
n ≤ 9

Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class. For how many fitness classes does Fitnasium cost less than or the same as Fit-quest?
Answers
Answer:
16
Step-by-step explanation:
50 + (5×16) 8×16
50 + 80 128
130. 128.
if she goes to gitnasium 1 more time then it eould be more than Fit-Quest.
16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been given that Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class.
Let the number of classes would be x
⇒ 50 + (5x) = 8x
Rearrange the terms of x in the above equation,
⇒ 8x - 5x = 50
⇒ 3x = 50
⇒ x = 50/3
Apply the division operation,
⇒ x = 16
Therefore, 16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.

Determine the constant of variation for the direct variation given.
R varies directly with S. When S is 16, R is 80.
1/5

16
Answers
Answer:
The constant of variation is k=5
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]y=k\cdot x[/tex]
Where k is the constant of proportionality.
We know R varies directly with S. Their relationship is:
[tex]R=k\cdot S[/tex]
We also have when S=16, R=80. Thus:
[tex]80=k\cdot 16[/tex]
Solving for k:
[tex]k=80/16=5[/tex]
The constant of variation is k=5

X = 15
Step-by-step explanation:
1.- Rewrite the equation, Put like terms on the same side
6x - 5x = 2 - 17
Instead of adding subtract
2.- Divide 1 on both sides
1x = 15
You should only have X on the left side
3.- You should have
X = 15

this is an inequality, could you explain as well? will give out brainliest answer :)
Answers
Answer:
x≥-8
Step-by-step explanation:
Let's do this step by step:
Step 1-
Take x/2≥-4. Now multiply both sides by 2 to isolate the x variable. Multiplying x/2 by 2 removes the denominator.
Step 2-
Since we are multiplying both sides by 2, we also have to multiply -4 by 2. We get -8
Step 3-
Therefore, x≥-8
