what is the property of equality of 2y − 40 = -18?
Answer:
Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;
2y-40 + 40 =-18+40
2y = 40-18
2y = 22
We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.
Dividing the resulting equation by 2:
2y/2 = 22/2
y = 11

Susan says that a solution to the equation x + 5 = 15 must also be a solution to the equation 2(x+1) = 22 write an explanation why this is true
9514 1404 393
Answer:
each equation can be transformed to the other
Step-by-step explanation:
Starting with the given equation, we can subtract 4, then multiply by 2:
x + 5 = 15
x + 5 - 4 = 15 - 4
x + 1 = 11
2(x + 1) = 2(11)
2(x +1) = 22 . . . an equivalent equation
The properties of equality allow one equation to be transformed into the other.

3-) Martha O'Brien made a deposit to her checking account at an ATM and received
$75 in cash. The checks deposited totaled $50 less than twice the currency amount,
and the total deposit was $25 more than the check amount. Determine the amounts
Martha deposited in checks and in currency as well as the total deposit.
Answer:
The amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175
Step-by-step explanation:
Since Total deposit (T) = currency (C) + coins + check (Ck) - cash received (Csh)
T = C + Ck - Csh. (1)
Given that cash received (Csh) = $75,coins = 0 and the checks deposited totaled $50 less than twice the currency amount. So,
Ck = 2C - $50 (2)
Also, total deposit was $25 more than the check amount. So,
T = Ck + $25 (3)
Substituting equation (2) into (1), we have
T = C + Ck - Csh
T = C + 2C - $50 - Csh
T = 3C - $50 - $75
T = 3C - $125 (4)
Substituting equation (2) into (3), we have
T = Ck + $25
T = 2C - $50 + $25
T = 2C - $25 (5)
Equating equations (4) and (5), we have
3C - $125 = 2C - $25
Collecting like terms, we have
3C - 2C = $125 - $25
C = $100
Substituting C into (2), we have
Ck = 2C - $50
Ck = 2($100) - $50
Ck = $200 - $50
Ck = $150
We now compute T
T = C + Ck - Csh.
T = $100 + $150 - $75.
T = $250 - $75
T = $175
So, the amount Martha deposited in checks is $150
The amount Martha deposited in cash is $100
The total deposit is $175

A rectangular prism has a length of 13ft and a width of 16ft.
If the prism has a volume of 936ft3, calculate the height of
the prism. Make sure your answer includes the proper units.
Considering the volume of the rectangular prism, it is found that it's height is of 4.5 ft.
What is the volume of a rectangular prism?The volume of a rectangular prism of length l, width w and height h is given by:
[tex]V = lwh[/tex]
In this problem, the measures given are as follows:
l = 13 ft, w = 16 ft, V = 936 ft³.
Hence, the height, in ft, is found as follows:
[tex]V = lwh[/tex]
[tex]13 \times 16 \times h = 936[/tex]
[tex]h = \frac{936}{13 \times 16}[/tex]

This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the
base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the
base?
A cubic inches
(b) The crystal is actually half an inch thick on each of the sides and on the bottom.
Approximately how much space is contained within the vase?
A cubic inches
The volume of the vase when the crystal itself has no thickness will be 240 inches³.
How to calculate the volume?The volume of the vase when the crystal itself has no thickness will be calculated thus:
V = Bh
V = (4in × 5in) × 12
V = 240 inches³
When the crystal is half an inch thick on each of the sides and on the bottom, the volume will be:
= 1/2 × 240 inches ³
= 120 inches³

Given the parent function f(x)=|x| , write the equation of the function g(x) whose graph is pictured.
(GRAPH W/ BLACK LINE IS THE PARENT FUNCTION FOR REFERENCE. Graph w/ the orange line is the one that needs an equation)
ANSWER:
g(x) = _____
Answer:
g(x) = 3|x - 2| - 4
Step-by-step explanation:
f(x) = |x|
vertex: (0, 0) → (2, -4)
point: (1, 1) → (3, -1)
⇒ g(x) = 3f(x - 2) - 4
⇒ g(x) = 3|x - 2| - 4
PLEASE HELP! WILL CROWN!! I need statements and reasons on DC and EF!!! plzzz
Answer:
DC⊥EF as the 2 angles in smallest triangle are 30 and 60 degrees, so the last one is 90 making Line DC perpendicular to Line EF.
Step-by-step explanation:
DC⊥EF means that Line DC is perpendicular (90 degrees) to EF.
To prove this, we can use the two angles of the small triangle created by the intersection of the triangles AEF and DCB.
The remaining angle of triangle AEF is 60, as all angles of triangles add up to 180 (so 180 - 12 = 60). This angle at F is shared with the little triangle.
Now we will get the angle at D using the triangle DCB. Since we are given two angles 90 and 60, angle D has to be 30.
So of our little triangle, we have angles 30 and 60, meaning the last one is 90 degrees and hence, DC⊥EF

Which of the following is NOT true about the following equation? y=−3
A) It is the equation of a horizontal line.
B) Its slope is zero.
C) It is perpendicular to the equation y=13x+2.
D) The line does not cross the x-axis.
Answer:
The statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2 ⇒ C
Step-by-step explanation:
Let us revise the facts of the horizontal line:
The line is horizontal if all points on it have the same y-coordinatesThe horizontal line is parallel to the x-axisThe slope of the horizontal line is zeroThe equation of the horizontal line is y = b, where b is the y-coordinate of all points on the lineThe y-intercept of the horizontal line is (0, b)∵ The equation of the line is y = -3
→ Which means the value of y = -3 at any value of x
∴ The line is horizontal
∴ Its slope = 0
∵ The horizontal line is parallel to the x-axis
∴ The line does not intersect the x-axis
∴ The true statements are:
It is the equation of a horizontal lineIts slope is zeroThe line does not cross the x-axisThe statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2
