What is the image of (-7, -9) after a reflection over the x-axis?
Answers
Answer:
(-7,9)
Step-by-step explanation:
When you flip over the x-axis, the y-value changes its sign. Vice versa.
[tex]\huge\boxed{\boxed{\bold{(-7, 9)}}}[/tex]
[tex]\hrulefill[/tex]
To reflect a point across the [tex]x[/tex]-axis, multiply or divide its [tex]y[/tex] coordinate by [tex]-1[/tex]:
[tex]P'=(-7, -9*-1)[/tex]
Multiply:
[tex]P'=\large\boxed{(-7, 9)}[/tex]
An image is attached showing the original point ([tex]P[/tex]) and its image ([tex]P'[/tex]).

Step-by-step explanation:
a²-b²
=a²-ab+ab-b²
=a(a-b)+b(a-b)
=(a+b)(a-b)
it'll be more easy to understand if u try solving it the other way(from bottom to the top)
there fore... a²-b²=(a+b)(a-b)
and -20+1=-19
so then the ans will be(a+b)(a-b)-19

Rocco can do 60 jumping jacks in 1 minute. How many jumping jacks can he do
in 8 minutes?
Answers
Answer: 480 Jumping jacks
Step-by-step explanation: What I did was 60 * 8= 480
60 Jumping Jacks=1 minutes
120 Jumping Jacks=2 minutes
continue, continue
The number of jumping jacks can he do in 8 minutes is 480 if Rocco can do 60 jumping jacks in 1 minute.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Rocco can do 60 jumping jacks in 1 minute.
60 Jumping Jacks = 1 minutes
120 Jumping Jacks = 2 minutes
= 60x8
= 480
Thus, the number of the jumping jacks is 480.

It's Side Splitter Theorem
Answers
Answer:
B
Step-by-step explanation:
The sections of the parallel roads split by the transversals are in proportion, that is
[tex]\frac{350}{300}[/tex] = [tex]\frac{first}{1650}[/tex] ( cross- multiply )
300 first = 577500 ( divide both sides by 300 )
first = 1925 ft
Thus
Elm st → Maple st = 1925 + 350 = 2275 ft → B

What value of x with make the equation below true?
1/2 (2x + 8) = 3x + 8 - x
Please help
Answers
Answer:
Step-by-step explanation:
1/2 (2x+8)=3x+8−x
Use the distributive property to multiply 1/2=0.5 by 2x+8.
1/2 x 2x+1/2x8=3x+8-x
Cancel out 2 and 2.
x+1/2 ×8=3x+8−x
Multiply 1/2 =0.5 and 8 to get 8/2=4.
x+8/2=3x+8−x
Divide 8 by 2 to get 4.
x+4=3x+8−x
Combine 3x and −x to get 2x.
x+4=2x+8
Subtract 2x from both sides.
x+4−2x=8
Combine x and −2x to get −x.
−x+4=8
Subtract 4 from both side
−x=4
Multiply both sides by −1.
x=−4

An object is moving at a speed of 11 yards every 6 months. Express this speed in centimeters per hour. Round your answer to the nearest hundredth.
Answers
Answer:
its c
i took the quiz
Step-by-step explanation:
The speed in centimeters per hour is 0.2328 centimeters per hour.
Given,
An object is moving at a speed of 11 yards every 6 months.
We need to find this speed in centimeters per hour.
How many centimeters in one yard?1 yard = 91.44 centimeters.
We have,
11 yards every 6 months
11 yard = 6 months
1 month = 30 days
1 day = 24 hours
30 days = 30 x 24 hours
30 days = 720 hours
1 month = 720 hours
6 months = 6 x 720 hours
6 months = 4320 hours
11 yards = 4320 hours
1 yard = 91.44 cm
11 x 91.44 cm = 4320 hours
1005.84 cm = 4320 hours
So,
we will find how many cm per hour.
if 1005.84 cm = 4320 hours then,
Dividing both sides by 4320.
1005.84/ 4320 cm = 4320/4320 hours
0.2328 cm = 1 hour
Rounding to the nearest hundredth.
0.23 cm = 1 hour
Thus the speed in centimeters per hour is 0.2328 centimeters per hour.
