Answer:
Step-by-step explanation:
A) y + ? = n^2 - 16n + ? + 69
y + 64 = n^2 -16n + 64 + 69
y + 64 = (n-8)^2 + 69
y = (n-8)^2 + 5
B) vertex is (8,5) because the value of a vertex is always (h,k) from the parent vertex function:
y = a(x-h) + k
it's a minimum only because the (a) value is positive
C) axis of symmetry = 8

Are the graphs of the lines in the pair parallel? Explain,
y = 3x - 17
4x - 6y = -6
A.)Yes, since the slopes are the same and the y-intercepts are the same.
B.)No, since the y-intercepts are different.
C.)No, since the slopes are different.
D.)Yes, since the slopes are the same and the y-intercepts are different.
Answer:
C
0 No, since the slopes are different.
Step-by-step explanation:
First, solve the second equation.
-6y=-16-4x
6y=16+4x
y=16/6+4/6x
y=2/3x+8/3
Next, look at the equation of a line's format.
y=mx+b
This means y=(m=slope)*x+b[when x=0, y=b]
In the first equation, y=3x-17, we can see that m=3, and b=-17
In the second equation, y=2/3x+8/3, m=2/3, and b=8/3
We know that m is the slope, and 3 does not equal 2/3.
Lines are only parallel when their slopes are the same
Therefore, the two lines are not parallel since the slopes are different.

3(x+2
Ox= 24
3x + 6
Ox=8
3x +
Answer:
x = 6
Step-by-step explanation:
3(x + 2) =24
Divide each side by 3
3/3(x+2) = 24/3
x+2 = 8
Subtract 2 from each side
x+2-2 = 8-2
x = 6
what is the area of the parallelogram
A. 11in2
B. 22in2
C. 45in2
D. 60in2
Answer:
Step-by-step explanation:
Area of a parallelogram is base times height. So 15x4
It’s 60in^2
So D
Answer:
D. 60 inches^2
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the height is 4 inches, and the base is 15 inches. Therefore, we can substitute 4 in for h and 15 in for b.
a=4*15
Multiply 4 and 15
a=60
Area is always units^2. We know the units are inches, therefore the area is:
60 inches^2, or choice D

Which line has a slope of -2 and goes through the point (-2, 3) ?
y=−2x−1
y=−1/2x+3
y=1/2x−5
y=2x+1
Answer:
y=-2x-1
Step-by-step explanation:
Since the m term in this equation (the number that comes right before the x) is -2, that means that the slope of this line is -2.
Jodi learned to sing a total of 4 pieces over the course of 2 weeks of voice lessons.
After 8 weeks of voice lessons, how many pieces will Jodi be able to sing in total?
Assume the relationship is directly proportional.
A: 16 pieces
B: 20 pieces
C: 15 pieces
D: 12 pieces
Answer:
A. 16 pieces
Step-by-step explanation:
If Jodi learned to sing a total of 4 pieces over the course of 2 weeks of voice lessons, after 8 weeks of voice lessons, Jodi be able to sing 16 pieces.
2 x 2 =4
8 x 2= 16
Therefore the answer is 16.

On a coordinate plane, triangle A B C has points (negative 3, negative 1), (negative 2, negative 3), (1, negative 1) and is reflected across y = 1. Reflect the figure over the line y = 1. Which is point A’ after the reflection? A’(–3, 1) A’(–3, 3) A’(–3, 2) A’(1, 1)
Answer:
A' = (-3, 3)
Step-by-step explanation:
If the points are as follows:
A = (-3, -1)
B = (-2, -3)
C = (1, -1)
When reflecting across a y axis the x values remain the same.
When reflecting across y = 1 the y values will remain equal distant from y = 1.
A' = (-3, 3) y value = |-1 - 1| = 2 + 1 = 3
B' = (-2, 5) y value = |-3 - 1| = 4 + 1 = 5
C' = (1, 3) y value = |-1 - 1| = 2 + 1 = 3
Answer:
A' = (-3, 3)

Evalaute the expression 3x + (z+2y)-12, if x=3, y=8 and z=5
please help rn
Answer:
18
Step-by-step explanation:
3x + (z + 2y) - 12, if x = 3, y = 8 and z= 5.
3*3 + (5+2*8) - 12
9 + (5 + 16) - 12
9 + 21 - 12
30 - 10 - 2
20 - 2
18
Answer:
18
Step-by-step explanation:
First what you would do is plug in the numbers.
3x3+(5+2x8)-12
Then you would multiply 2 times 8 and get 16. Then add 16 and 5 and get 21.
3x3+(21)-12
Then you add 3 times 3 and get 9.
9+21-12
Then you solve left to right. Then you add 9 and 21 and get 30. Last you subtract by 30 by 12 and get 18.

Write the equation of the quadratic function in standard form represented by the graph.
Answer:
y = x^2 +6x+8
Step-by-step explanation:
First find the zeros, -4 ,-2
y =a (x - -4) (x - -2)
y = a(x+4)(x+2)
Then it is multiplied by a constant so pick a point on the curve and solve for the constant
We will use (0,8)
8 = a(0+4)(0+2)
8 = a(8)
a =1
y = (x+4)(x+2)
Writing in standard form
FOIL
y = x^2 +2x+4x+8
y = x^2 +6x+8

What is graph of a function?The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x).
Given,
Graph of a parent function
and equation is graphed along with the parent function
Parent function
f(x) = ∛x
By the graph,
There is 3 unit horizontal shift to positive side, and 4 unit vertical shift to upwards in parent function
Thus, function drawn along with it is
g(x) = ∛(x-3) + 4
Hence, g(x) = ∛(x-3) + 4 is the equation, graphed along with the parent
function.
