Form quadratic functions using the following properties: f(2)=f(4)=0 and f(3) = -2
Answers

Answer:
f(x) = 2x^2 -12x +16
Step-by-step explanation:
The zeros tell you the factored form is ...
f(x) = a(x -2)(x -4)
Then f(3) is ...
f(3) = -2 = a(1)(-1) = -a
a = 2
So the factored function is ...
f(x) = 2(x -2)(x -4)
Expanded to standard form, we get ...
f(x) = 2x^2 -12x +16

Step-by-step explanation:
x-9=15 will equal to 24 so x=24
if Allison is 15 but she is 9 years younger then Pam, Pam is x, so all you have to do is count up from 15, so 15+9 which equals 24 Pam is 24 making F the right choice

Create an equation with one solution of x = −5.
9x − (x − 3) = 2x − (__ + x)
7.4 #7
Answers
Answer:
9x-(x-3) = 2x - (-5 + x)
Step-by-step explanation:
Let's say blank is the variable a.
9x-(x-3) = 2x - (a + x)
Simplify the equation:
9x-(x-3) = 2x - ( a + x)
9x - x + 3 = 2x - a - x
8x + 3 = x - a
7x + 3 = -a
a = -7x - 3
Plug in -5 for x:
a = -7*-5 - 3 = 35 - 3 = 32
a = 32 so the equation with one solution of x = -5 would
9x-(x-3) = 2x - (-5 + x)

Answer:
f −1 (x)= x/2+3
Step-by-step explanation:
Here take y=f(x)
Then y=2x−6
⇒2x=y+6
⇒x= y/2 +3
Now switch x and y in the resulting equation. The resulting function of x is the inverse.
⇒y= x/2 +3
Thus the inverse function is f −1 (x)= x/2+3

Answers
Answer:
A. 0, - 9
Step-by-step explanation:
Given
x² + 9x = 0
x (x + 9 ) = 0
Either
x = 0
or,
x + 9 = 0
x = - 9
Hope it will help :)
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
x² + 9x = 0
To solve for x, we can factor the expression:
x(x + 9) = 0
According to the zero product property, this equation is satisfied if either x = 0 or x + 9 = 0.
We have two solutions:
x = 0 or x = -9
Therefore,
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.

Answers
Answer:
X=11y+4 y= -1/11x + 4/11
Step-by-step explanation:
Let's solve for x.
8x+4y+24−7x+7y=28
Step 1: Add -24 to both sides.
x+11y+24+−24=28+−24
x+11y=4
Step 2: Add -11y to both sides.
x+11y+−11y=4+−11y
________________________________
answer: x=−11y+4
_______________________________
Let's solve for y.
8x+4y+24−7x+7y=28
Step 1: Add -24 to both sides.
x+11y+24+−24=28+−24
x+11y=4
Step 2: Add -x to both sides.
x+11y+−x=4+−x
11y=−x+4
Step 3: Divide both sides by 11.
11
11y/11 = - x+4/11
y=-1/11x +4/1

Identify the independent and dependent variables.
The equation A=25w represents the area A (in square feet) of a rectangular dance floor with a width of w feet.
Answers
‘w’ would be the independent variable
say, y = x+3, then they value y can have depends on what the value of x is. another way to put it is the dependent variable is the output value and the independent variable is the input value. so for y = x+3, when you input x =2, the output is y = 5.

There were 52 riders on a bus. The next bus had 25% more riders. How many riders were on the next bus?
Answers
Answer:
65 riders
Step-by-step explanation:
52 times 0.25 = 13 (25% of 52)
52 + 13 = 65
Answer:
There were 65 riders on the next bus.
Step-by-step explanation:
To solve this you have to know what 25% of 52 is, and since 25% of 52 is 13, you have to add 52 and 13 so you get 65 as your result.
