Your friend is correct.
When a figure is reflected, it is flipped. Since it is reflected on the x-axis, that is the direction it is flipped in. When flipped, the coordinate of the bottom left corner is (1, 1). When you move the figure over 5 units (which is what translating is), the coordinates are (-4, 1) which matches with the corner of the second given figure.

15. What is the y-intercept, axis of the symmentry and vertex of the following function
f(x)=-3x²-6x-5
Answers
Axis of sym: x = -1
Vertex: (-1,-2)
Y intercept: y = -5
The y-intercept is c so it’s (-5)
Axis of the symmetry u get by using -b/2a and you get (-1 )
Vertex u apply -1 in the equation and u get (-1,-2)
The -1 is the x u got on axis of symmetry and -2 is the y which u get by applying the x= -1 in the formula of f(x)
Part A.Maggie is making a necklace using 14 inch string and identical beads. Maggie has placed 12 beads next to each other starting at the left end of the string as shown in the figure. The 12 beads fill 3 inches of the string. How many total beads will completely fill the 13 inch string?
Part.BAfter filling the string from end to end, Maggie decides to leave one inch at each end of the string with no beads. How many beads does she need to remove from the beads she used to completely fill the string?
Answers
12/3=4
4*13=52
Part b: 8 beads
Every inch is 4 beads.
4*2=8
Answer:
a) 56 beads
b) 8 beads
Step-by-step explanation:
12 beads take 3 inches so yes 12/3 =4 per inch
but then the necklace is 14 in long so 4 *14=56 beads
if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads

If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?
Answers
First you need to converted miles into km as she was driving with miles but our speed limit is km so to maintain the balance we have to convert the measurements into one unit
Speed limit was 80km
She was driving 75 miles
We know,
1 mile = 1.609 km
So 75 * 1.609 = 120.675 km
So speeding = (120.675 - 80)
= 40.675
Therefore, she was over 40 km speed limit

To solve this problem, all you have to do is isolate the term of c from one side of the equation.

Bradley has a coupon for 15% off the price of a computer. The sales tax is 8%.
How much money did Bradley save, including sales tax, by using his coupon?
(Total cost of the computer with sales tax and coupon is $454.41)
Answers
Answer: $31.81
Step-by-step explanation:
First figure out how much the sales tax was
454.41x0.8=36.35
Then figure out how much the coupon subtracted off the total price
454.41x0.15=68.16
Subtract 68.16 by 36.35
68.16-36.35=31.81

Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.
Answers
Answer:
I dont know about A but the answer for B is below
Step-by-step explanation:
6x + 4 = 34 = (6x5) + 4 = 34
Answer:
Seem you are doing the same test I did! Module 7 part 2?
Anyway!
Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6 = 24.
Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.
And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.
Part B:
6x + 4 = 34
6x5 = 30
30+4=34
To verify: (6*5) + 4 = 34. The answer is five.
