Answer:it wouldn’t change the shape but it would change the location of the shape
Step-by-step explanation:
Solve for X. Type in your numerical answer only, do not type the degree symbol.
20x + 5
24x - 1
Answer:
x = 4
Step-by-step explanation:
Due to the Consecutive Interior Angles rule, c + e = 180. So, 20x + 5 + 24x - 1 = 180.
If you solve, you will get x = 4
Work:
20x + 5 + 24x - 1 = 180 [Add like terms]
44x + 4 = 180 [Isolate the variable]
44x = 176 [Solve]
x = 4
12. You are saving for a bike and can save $10 per week. You have $25 when you begin saving.
# of weeks
1
2
3
4
5
6
7
Amount of money saved
Explanation:
Answer:
$95
Step-by-step explanation:
I you need to see how much you would save after 7 weeks, and you save $10 a week, that would be 7*$10 and if you start with $25 you add it.
$25 + 7*($10) =
$25 + $70 = $95
After 7 weeks you would have saved $95.
If you need to know your savings each week, start with $25, and add $10 to it each week.
$25
Week 1 - $25 + 10 = $35
Week 2 - $35 + 10 = $45
Week 3 - $45 + 10 = $55
Week 4 - $55 + 10 = $65
Week 5 - $65 + 10 = $75
Week 6 - $75 + 10 = $85
Week 7 - $85 + 10 = $95

explain proportionality to me 7th grade math
If two quantities a and b are directly proportional to one another, then both a and b change in the same direction.
For example, if the amount/volume of coffee I have in a cup is directly proportional to the total volume of the cup, then the larger the cup gets, the more coffee I can fill it with. On the other hand, if the cup gets smaller, the amount of coffee it can hold also gets smaller.
Both a and b don't necessarily change at the same rate, though, which means one of these needs to get appropriately scaled by some factor k, so that
a = kb
Continuing the coffee example: Suppose I only fill my cup halfway. If the total volume of the cup is a, then the amount of coffee I pour in is b = 1/2 a. So the relationship of these two quantities is governed by the equation,
a = 2b
and in this case, k = 2.
If instead a and b are inversely proportional, this means as one quantity changes, the other changes in the opposite direction.
Suppose I have two cups that I use for coffee that can both hold the same amount k if they are filled completely, but one cup is taller than the other. In order for both cups to be able to hold the same volume of coffee, the taller cup must have a thinner profile.
The cups are cylindrical, so that their volumes are equal to the products of the area of their base a and their height b. If one cup is twice as tall as the other, then for the smaller cup we could have
ab = k
and for the taller one,
a (2b) = k
But in order to get the same volume, the quantity a for the shorter cup must be cut in half to preserve equality:
(1/2 a) (2b) = ab = k
So one quantity is doubled (increases), while the other gets halved (decreases).

The table represents the function f (x) = 5x - 8.
Find f(-4):
f(-4)= 5(-4)-8
f(-4) = -28
Answer:
a=-18
b=7
c=27
Step-by-step explanation:
Given the function f (x) = 5x - 8 ,for different value of f(x)
f (-2)=-18
f (-2)=7
f (-2)=27
How to solve function?
A) for f (x) = 5x - 8 where f (-2).
⇒ f (-2) = 5x - 8
⇒ f (-2) = 5(-2) - 8
⇒ f (-2) = -10 - 8
⇒ f (-2) =-18
B) for for f (x) = 5x - 8 where f (3).
⇒ f (3) = 5x - 8
⇒ f (3) = 5(3) - 8
⇒ f (3) = 15 - 8
⇒ f (3) =7
C) for f (x) = 5x - 8 where f (7).
⇒ f (7) = 57 - 8
⇒ f (7) = 5(7) - 8
⇒ f (7) = 35- 8
⇒ f (7) =27

The intersection of two planes contains at least two points.
A.) always
B.) Sometimes
C.) Never
Answer:
A
Step-by-step explanation:
The solution is Option A. Always
The intersection of two planes contains at lease two points
What is intersection of two planes?
When two planes intersect, they form a line.
The vector equation for the line of intersection is given by
r = r₀ + tₓ
where r₀ is a point on the line
tₓ is the cross product of the normal vectors of the two planes.
The parametric equations for the line of intersection are given by
x = a , y = b and z = c
where a, b and c are the coefficients from the vector equation
r = a (i) + b (j) + c (k)
The line of intersection will be perpendicular to the normal of both the planes
The line of intersection lies on both the planes
Therefore , a line is observed at the intersection of two planes
Hence , the intersection of two planes always contains at least two points and it forms a line
