1. Dilation by a scale factor of 4 followed by reflection over the x-axis

2. Dilation by a scale factor of 2 followed by reflection over the x-axis

Answer:

Multiply the rate per hour by the number of hours (n) and add the deposit.

A)

Bike shop x: c = 2.75n + 3.00

Bike shop z: c = 1.75n + 7.00

B) to find when they will cost the same set the equations equal to each other and solve for n:

2.75n + 3.00 = 1.75n + 7.00

Subtract 3 from each side:

2.75n = 1.75n + 4.00

Subtract 1.75n from both sides:

1.00n = 4.00

Divide both sides by 1:

n = 4 hours

Answer: The width of the court needs to be 5.32 inches to maintain proper proportions.

Step-by-step explanation: We make the length of court 10 inches. Now let us convert 94 feet in the ratio of 10 inches. We can convert 94 feet into 10 inches by dividing the number 94 with 9.4

Therefore

Thus, divide 50 feet with 9.4 feet. So that you can maintain proper proportion in drawing.

Hence, the width of the court needs to be 5.32 inches to maintain proper proportions.

The Answer is:

53 inches

Answer:

-2/3n + 7 = 15

-2/3n = 15 + 7

-2/3n = 22

n = 2/3 + 22

n = 24/3

n = 8

Answer:

2 greater than or equal to-9

Step-by-step explanation:

since the graph has an equation of x²+2x-8

to find the value of x when y=0 find two numbers that if you multiply them together it will give you -8 and if you add them they will give you +2

+4x-2=-8

+4+(-2)=+2

so x²+2x-8=0

can be writteb as (x+4)(x-2)=0

so one time x+4=0 so x=-4

and one time x-2=0 so x=2

so x roots at -4 and 2

to find y when x=0

0²+2(0)-8=-8

so y root at -8

(shown in graph above)

the range is from minimum point to the maximum(down to up) for the y values

there is no maximum point so the graph goes to infinity

the minimum is the middle point between the two x roots so take an average of them

(-4+2)÷2=-1

so when x=-1

(-1)²+2(-1)-8=-9

so the minimum starts from -9 going up to infinity

so the answer is greater or equal to-9

Answer:

1: 1000 sq. ft.

2: you will need at least 4 gallons of paint.

3: you will need 2,400 cubic ft of water.

Step-by-step explanation:

(p.s. sorry its a bit long)

so we need to start by acknowledging that the pool's sides that will be painted are 5 out of the 6 surfaces.

since we will be painting the walls and floors of the pools we need to figure out their areas.

we know that area can be found by using the formula A=lw

so by implementing this into the measurements we need we can figure out how much area needs painting.

A = 4(20)

80sq. ft.

A = 4(20)

80sq. ft.

A = 4(30)

120sq. ft.

A = 4(30)

120sq. ft.

A = 30(20)

600sq. ft.

now we have all our measurements (notice how I only used the last measurement once)(its because we won't be painting the top and bottom of the pool since the pool has no "top")

by adding all of them together you can figure out how much area is going to be painted.

80 + 80 + 120 + 120 + 600 = 1000sq. ft.

now we know that a total of 1000sq. ft. is going to be needing paint

leading us to the next question how many gallons of paint will we need

we know that 1 gallon will paint 300 but we need to paint 1000

so let's say we get three gallons of paint, which should cover 900sq. ft. but we still need a bit more

so we can say we will need at least 3.5 gallons of paint if we want a whole number we can say we will need at least 4 gallons of paint.

ok last but not least we need to figure out how much water we will put in the pool so in order to figure this one out all we have to do is use the formula for volume

which is

V = lwh (volume = length times width times hight)

so substitute the letters with number

V = (30)(20)(4)

now multiply all of them together

Our answer for this one will be

2,400 cubic feet

ok so basically one important thing to remember is when we talk abt surface area or area in general in math they use squared (sq.)(^2) but when we are talking abt volume we are supposed to use cubic (^3) and then we finish with the type of measurement we are using, for example, ft (feet) cm (centimeter), etc...

alrighty, thank you hopefully this helps u understand better.

Answer:

1. 2x4=8

  2x3=6

2. 3x4=12

   3x3=9

Step-by-step explanation:

Hello :)

In this problem, you have to create an equation to figure out the length of each bar. The first bar has two sets of 3 blocks; you can see each set by a color change.

Therefore, this equation would be 2 times 3, since there are 2 sets of 3. This answer equates to 6.

The next one has two bars of four blocks. This means it is 2 times 4, because there are two sets of 4 blocks, and this would constitute as the answer 8.

The second question is a bit tricker. If we look at the first bar, we see that there are 3 blocks per set (noted by color change) and we have 3 of those. If we count all of those up, they have 9 blocks overall. After all, 3 times 3 is nine.

The other problem has 4 blocks a set, and there are three of those. 4 times 3 is 12.
