Step-by-step explanation:
we will put -22 in the value of y
-22=5x-7
x will go the left hand side and will shift -22 and 5x
-5x= -7+22
-5x=+15
x=+15/-5
we will simplify it by 5 because both the numbers come in 5 time table
x=+3/-1
x=-3
so the value of x is -3

Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. What does the ratio 5 : 13 represent in this situation? Use a model to show your work. Explain your reasoning.
Answer:
m
Step-by-step explanation:
The ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias in Myra's flower bed.
A ratio shows us the number of times a number contains another number.
Given that Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. Therefore, the ratio of number of Lilies to the number of tulips and zinnias are,
Ratio = Number of Lilies : Number of tulips and zinnias
Ratio = 5 : (7+6)
Ratio = 5 : 13
Hence, the ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias.

Is 78 a multiple of 6 SHOW YOUR WORK FOR BRAINLIST
Answer:
Yes, it is
Step-by-step explanation:
Given
[tex]Number = 78[/tex]
Required
Determine if it is a multiple of 6 or not
A number is a multiple of 6 if and only if it can be divided by 6 without remainder.
Can 78 be divided by 6?
To check, we have:
[tex]Check = \frac{78}{6}[/tex]
[tex]Check = 13[/tex]
The result of the division has no remainder.
Hence, it is a multiple of 6
Observe the graph below. The scale factor used to dilate ABC was...
Answer:
3
Step-by-step explanation:
AB = 1 unit
A'B' = 3 units
The scale of dilation = A'B'/AB
Therefore:
scale of dilation = 3 units / 1 unit = 3
This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.

What is the volume of this figure?
Answer:
It’s 850
Step-by-step explanation:
Divide the figure into 3 shapes, first one being 10ft times 5ft times 5, followed by 20 times 5 times 5 the another with 10 times 5 times 5. I got 850
Answer:
It is 875 cubic feet
Step-by-step explanation:
If you split it into three shapes:
1) Left vertical cuboid is 10x5x5 = 250
2) Middle horizontal cuboid is 15x5x5 = 375
3) Right vertical cuboid is 10x5x5 = 250
Total volume is 875 cubic feet

NOTE: Angles not necessarily drawn to size . what is x?
Answer: 45
Step-by-step explanation: 160-115= 45 you do this because the angles are across the vertex from each other.
Answer:
X=45
Step-by-step explanation:
Method 1 ( the long one)
So AED and CEB are vertical angles, that means that the are the same and have the same value.
So 115 plus x equal 160.
115 + x = 160
from there we just have to subtract 115 from both sides to get x by itself.
115 + x = 160
-115 -115
_________________
x=45
Method 2 (short one
If you know that those are vertical angles, then just subtract 115 from 160 and there you go. You get 45.

List the key features of the quadratic equation y = x2 + 6x - 16.
A. x-intercepts: (-8,0) and (2,0), y-intercept: (0,–16), vertex: (-3,-25).
B. X-intercepts: (-8,0) and (2,0), y-intercept: (0,–6), vertex (-3,-25).
C. X-intercepts: (8,0) and (-2,0), y-intercept: (0.-16), vertex: (-3,-25).
D. x-intercepts: (-8,0) and (2,0), y-intercept: (0,16), vertex: (-3,-25).
Answer:
Correct choice is A
Step-by-step explanation:
Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The x-intercepts are the points where the graph of the function crosses the x-axis, they are also called zeros or roots. They can be found by solving the equation y=0,
The y-intercepts are the points where the graph of the function crosses the y-axis. They can be found by setting x=0.
We are given the function:
[tex]y = f(x)=x^2+6x-16[/tex]
Find the y-intercept. x=0:
[tex]f(0)=0^2+6*0-16=-16[/tex]
y-intercept: (0,-16)
Find the x-intercepts, y=0. Solve the equation
[tex]x^2+6x-16=0[/tex]
Factoring:
[tex](x-2)(x+8)=0[/tex]
Which gives x=2, x=-8.
X-intercepts (2,0) (-8,0)
This leaves us only choice A as correct. But we'll compute the vertex also.
Completing squares:
[tex]y=x^2+6x-16=x^2+6x+9-16-9=(x+3)^2-25[/tex]
Comparing with the vertex form of the function, we have: h=-3, k=-25, thus the vertex is located at (-3,-25)
This confirms that the correct choice is A

Answer:
56p
Step-by-step explanation:
dude it's mad easy just add it regularly then just add the p or other variable
Answer:
21+35p= 56p
Step-by-step explanation:
First, you take the numbers 21 and 35 and then add them.
Second, you take the variable (p) that you removed from 35 and add it to the end of 56.
This is to be done because you may separate the variable in order to find the solution but once done you must add the variable back in its place or else you will get the wrong solution.
