What is the image of (-7, -9) after a reflection over the x-axis?

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

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.

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.

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

Answer:

Step-by-step explanation:

For a:

ax = c - by

a = (c - by)/x

For x:

ax = c - by

x = (c - by)/a

For b:

by = c - ax

b = (c - ax)/y

For y:

by = c - ax

y = (c - ax)/b

Since all of them have the denominator as 100,

the total no. of sweets must be 100. So,

No of strawberries= 100-15-40-35

(a+b)(a-b)-19

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

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.

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.
