Point P′(−3, 2) is the image of point
P(3, 8) under a translation. What
is the image of (0, −6) under the
same translation?
Answer:
The image of (0, -6) after the same transformation is (-6, -12)
Step-by-step explanation:
After the required translation, the given image of the given point P(3, 8) is P'(-3, 2)
Therefore, the translation of preimage P(3, 8) to the image P'(-3, 2) is given by the difference between the coordinates as follows;
The translation from P(3, 8) to P'(-3, 2) = T(-3 - 3, 2 - 8) = T(-6, -6)
Therefore after the same translation, the preimage of (0, -6) will have an image given as follows;
Coordinate of preimage (0, -6) → T(-6, -6) (0, -6) = (0+ -6, -6 + -6) → Coordinate of image (-6, -12)
The image of (0, -6) after the same transformation = (-6, -12).

Answer:
h ( -6 ) = -13228
Step-by-step explanation:
h ( x ) = -10x^(4) - 9x^(2) - 8x + 8
evaluate when, x = -6
Substitute in -6, for x,
-10(-6)^(4) - 9(-6)^(2) - 8(-6) + 8
= -10(1296) -9(36) -8(-6) + 8
= -12960 - 324 + 48 + 8
= -13284 + 56
= - 13228
Explain how you can prove your observations in Questions 3 and 5 using a traditional proof. You don’t need to develop the steps of the proof; simply describe an approach that you might use. Which theorems might appear in your proof?(Hint: Draw a diagonal on the parallelogram to assist you in describing an approach.)
Answer:
A diagonal divides the parallelogram into two triangles. If I can prove that the two triangles are congruent, then the corresponding angles and corresponding sides of those two triangles must be congruent. To prove triangle congruency, I can use the properties of the angles formed when parallel lines are cut by a transversal.

Mario runs a yard company. He charges $20 to show up for the job and $4 for each 10 square Yards. His competition, Linda's Lawn Care, charges $10 for showing up and $6 for each square 10 yards. After how many 10 square yards are, they charging the same? And how much is charged at that moment?
Answer:
5 square 10 yards
$40
Step-by-step explanation:
Mario:
20 + 4x
Her competitor:
10 + 6x
Where,
x = number of 10 square yards
Equate the expressions
20 + 4x = 10 + 6x
Collect like terms
20 - 10 = 6x - 4x
10 =2x
Divide both sides by 2
x = 10 / 2
= 5
x = 5 square 10 yards.
Charge at that moment
Using any of the cost equation
10 + 6x
= 10 + 6(5)
= 10 + 30
= 40
$40
Or
20 + 4x
= 20 + 4(5)
= 20 + 20
= $40

slope is 4/3
Answer:
1.
IN a line if it looks like this it has a positive slope: / although if it looks llike this it has a negative slop:\.
That means only answers a and b can be correcct.
From the lowest point on the line to the highest, it is going up 2 units and to the left 1 unit. THis is -2/1 meaning the slope is -2.

What is the slope of the line through the points (0,-3) and (2,1)?
Answer:
alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1
okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)
let's follow the formula this makes it so we can solve! 1--3/2-0
I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2
this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1

What is the width of a rectangular prism that has a length of 4.5 feet, a height of 6 feet and a volume of 256.5 feet cubed? Please answer!
Answer:
9.5 feet
Step-by-step explanation:
To calculate volume, the formula is V = l*w*h.
We have the volume, length, and height, so we just need to plug it in to find the width. 256.5 = 4.5*w*6. Calculate this, and it'll become 256.5 = 27w. Then we divide both sides by 27 to find w. 256.5/27 = 27w/27. 9.5 = w. Width is 9.5 feet.
One year ago gas was $1.80 per gallon. The following year gas increased by 25%. What is the price for a gallon
of gas?
Answer:
2.25
Step-by-step explanation:
When finding these types of equations out you need to turn the percent into a decimal and then multiply it by the number. After getting your answer from that add it to the original number and that is how these types of equations works.
The new cost of gas for a gallon is $2.25
What is percentage?A relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part.
Given that, one year ago gas was $1.80 per gallon, the following year gas increased by 25%.
The previous cost of gas = $1.80
Cost is increased by = 25%
Therefore, new cost will be = 125% of $1.80
= 125 / 100 × 1.80
= 225 / 100
= 2.25
Hence, the new cost of gas for a gallon is $2.25

how do u find the slope of the line and for y=9x - 5/2
Answer:
slope = 9 y-intercept = -5/2
Step-by-step explanation:
since slope form is y=mx+b we know that m= slope and b=y-intercept. since 9 is in place of the m that shows that 9 is the slope. since 5/2 is in the b place you would think the y-intercept would be 5/2 but since the equation is - 5/2 instead of + 5/2 it would be + (-5/2) making the y-intercept negative. hope this helped. :)

Points on graphs choose all items which are true
Answer:
the 3rd 4th and 5th answers are true
Step-by-step explanation:
just substitute the points into the equations.
first equation, substitute the points 2,8 into the equation. 2 + 2(8) = 20.
2 + 16 = 20
18 = 20 is not a true statement.
second equation, substitute the points -1,5 into the equation. -1 + 2(5) = 10.
-1 + 10 = 10
9 = 10 is not a true statement.
third equation, substitute the points 7,7 into the equation. 2(7) - 7 = 7.
14 - 7 = 7
7 = 7 is a true statement.
fourth equation, substitute the points 7,-7 into the equation. 3(7) + -7 = 14.
21 + -7 = 14
14 = 14 is a true statement.
fifth equation, substitute the points 1, 1 into the equation. 2(1) + 6(1) = 8.
2 + 6 = 8
8 = 8 is a true statement.

Brenda has two pieces of string, one 28 feet long and the other 42 feet long. For an art project, she wants to cut them up to produce many pieces of string that are all of the same length, with no string left over. What is the greatest length, in feet, that she can make them?
Answer:
7 feet
Step-by-step explanation:
Length of one piece of string = 28 feet.
Length of the second string = 42 feet.
Since the number of required pieces was not given but many are required, the greatest length can be determined by;
If the maximum length is 7 feet, then:
the number of pieces from 28 feet long string = [tex]\frac{28}{7}[/tex]
= 4
Also,
the number of pieces from the 42 feet lone string = [tex]\frac{42}{7}[/tex]
= 6
Total number of 7 feet strings that she can make = 4 + 6
= 10
Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.
