Answer:y=(x-6)^2-4

Step-by-step explanation:

Answer:

f(x) = (x + 3)² - 13

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

Given

f(x) = x² + 6x - 4

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = x² + 2(3)x + 9 - 9 - 4

f(x) = (x + 3)² - 13 ← in vertex form

Answer: It’s A y > x^2-4

Y < x^2+3

[tex]\boxed{\sf \ 48 \ }[/tex]

Step-by-step explanation:

Hello,

the sum of all angles of the triangle at the left must be 180

so the last one is 180 - 80 - 60 = 40

and then the angle at the bottom left of the second triangle is 180 - 40 -72 = 180 - 112 = 68

and then the angle that we have to find is 180 - 64 - 68 = 48

hope this helps

Answer:

Answer is A

Step-by-step explanation:

(14x^4y^6)/(7x^8y^2)

because everything is one term, you can split into three terms

14/7, x^4 / x^8 , and y^6/y^2

multiplying these three terms will get us the starting term

14/7 = 2

x^4 / x^8

with division of exponents, you subtract the smaller exponent (4), from the big exponent (8), and leave it on the same side (bottom) as the big exponent

1/x^4

same thing with our y's

y^6/y^2

this time, the term stays on the top

y^4

take the simplified terms and multiply them together

(2) * (1/x^4) * (y^4) =

A: (2y^4) / (x^4)

Answer:

If you have this as an answer, 27

(The question is "what number is not part of the solution set to the inequality below?)

Step-by-step explanation:

w - 10 ≤ 16

w - 10 + 10 ≤ 16 + 10

w ≤ 26

11, 15, and 26 are all either less than, or equal to 26. Only 27 is not.

Answer:

We need a non-included side of one triangle

Step-by-step explanation:

By means of the AAS postulate.

The Angle-Angle-Side postulate (AAS) tells us that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean =\frac{12+17+52+52+52+81+85+89+93+94+96}{11}[/tex]

Mean =65.72

[tex]Median = \frac{n+1}{2} \text{th term}=\frac{11+1}{2}=6 \text{th term} = 81[/tex]

Mode = most occurring number = 52

Answer:

Graph A

Step-by-step explanation:

I graphed each of the inequalities on separate graphs below. When all the graphs are put together, they match Graph A.

The choice that matches the graph of the function as is defined to Graph A.

There are many tools we can use to find the information of the relation which was used to form the graph.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

The given function are;

f(x)= 2 ,if 2 < x ≤ 4

f(x)= 4, if 4 < x ≤ 6

f(x)= 6  ,if 6 < x ≤ 8

This means that how we get the staircase pattern as shown in graph A. This is considered a piecewise function since we're graphing pieces of various other functions.

Hence, The choice that matches the graph of the function as is defined to Graph A.

Answer:

(-1, -1/2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

( -11+9)/2 = -2/2 = -1

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

(0+-1)/2 = -1/2

Answer:

16cm^2

Step-by-step explanation:

Count all of the whole squares 1st

the do the ones at the sides

Answer: 16 units squared

If there is units for the grid, use those as your measurements, but if not, use each box to equal 1.

You can solve this by finding the area of a rectangle bigger than the original shape (straighten out diagonal lines)

Once you do this, count the units (boxes) of the length and width of the rectangle (5 X 4)

You would then multiply the length and width to find the area of the rectangle

5 * 4 = 20

..... But you still need to find the parallelogram so you have to subtract the space you filled in

Since the shape is a parallelogram, you can tell that the area filled in is equal on both sides, and when put together, they form a smaller rectangle

This rectangle would be 1 X 4

1 * 4 = 4

Then you have to subtract the smaller rectangle from the larger rectangle

20 - 4 = 16

Step-by-step explanation:

2 different sets of data can have the same mean:

for example

4, 5, 6 ---> has a mean of 5

hence it is NOT a fact that if the means are the same, that it must be the same data set

Answer:

x = 76

Step-by-step explanation:

PQ is a tangent to the circle at Q , thus the angle between the tangent and the radius is 90°

The sum of the 3 angles in the triangle = 180°, thus

x = 180° - (90 + 14)° = 180 - 104 = 76
