Answer:

Slope = -3/5

Step-by-step explanation:

slope (m) = y2 - y1 / x2 - x1

m = -2 - 1 / 1 - -4

m = -3 / 1 + 4

m = -3 / 5

You can check the work by counting rise (-3 which means 3 units down) over run (5 which means 5 units to the right)

Answer:

-3/5

Step-by-step explanation:

The line is y=-3/5x-1.4

Answer:

Any number above 4 will make this true.

Step-by-step explanation:

(5 x 4)/ 3 = 20/3 = 6.67 > 5

Answer:

Any number greater than 3.

Step-by-step explanation:

If you multiply 5 by any number greater than 3 and then divide it by 3 it will result in a number bigger than 5.

If you multiply the 5 by a number less than three, and then divide it by 3 it will result in a number less than 5 which makes the equation false.

You also can't multiply 5 by 3 and then divide it by 3 because it will make the answer equal to 5. This makes the equation false.

Answer:

The negative exponent rule tells us that a number with a negative exponent should be put in the denominator, or the numerator, depending on where the number is.

Step-by-step explanation:

Find the rate that was charged for Lara's time

       rate = dollars / hour

The use this rate to calculate how many hours it took to clean Roy's house, since the rates are the same.  Solve for hours.....

      rate for Lara = dollars / hour        =  $150 / 3 hour   =     $50 / hour

     rate for Roy = dollars / hour         Solve for hours

                                                            multiply both sides by hours

     (rate for Roy) (hour) = (dollars / hour) (hour)

     (rate for Roy) (hour) = (hour) (dollars / hour)       right side hours cancel

     (rate for Roy) (hour) = (dollars)     divide both sides by (rate for Roy)

     (rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

                       now the rate for Roy on the leftside cancel

     (rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

     (hour) = (dollars) / (rate for Roy)           Plug in $225 charged to Roy

                                                                     and the $50 / hour rate

       hour = $225 / ($50/hour)             ( 1 over 1 / hour )  = hour  

                = $(225/50) hour            think about  1 / (1/2)  = 2  the same with units

      hour =  4.5 hours

Answer:

The cost of the material for the full-sized pad is;

d) 222,750.00

Step-by-step explanation:

The parameters of the steel pad and the scale model are;

The volume of the deck = 18 yd³

The dimensions of the model of the same material = 6 feet by 4.5 feet and 4.5 inches thick

The weight of the sample, m₂ = 75 lbs

The cost of the steel, P = $55/lb

The dimensions of the sample in yards are;

6 feet = 2 yards, 4.5 feet = 1.5 yards, and 4 inches = 0.[tex]\overline 1[/tex] yards

The volume of the sample, V₂ = 2 yd. × 1.5 yd. × 0.[tex]\overline 1[/tex] yd. =  (1/3) yd.³

The density of the sample material, ρ = m₂/V₂

∴ The density of the sample material, ρ = 75 lbs/((1/3)yd.³) = 225 lbs/yd³

Therefore, the density of the material of the pad, ρ = 225 lbs/yd³

The mass of the steel  pad, m₁ = ρ × V₁

∴ The mass of the steel  pad, m₁ = 225 lbs/yd³ × 18 yd³ = 4,050 lbs

The cost of the material for the full-sized steel pad, C = m₁ × P

∴ C = 4,050 lbs × $55/lb = $222,750

Answer: The answer is D

Step-by-step explanation:

Circle A has translated 2 units to the right and  8 units up to produce circle B ad circle B was reduced by a factor of 3/4

Given the equation of circles A and B defined as  (x-5)^2+(y-6)^2=16 and (x+3)+(y+2)^2=9

The scale factor of a dilation is given as:

k = √9/√16

k = 3/4

From the centers, we can see that circle A has translated 2 units to the right and 8 units up to produce circle B

Answer:

False your answer will 4x-16

Step-by-step explanation:

you have to distribute 4 to x and 4 to 4. so you will do 4*x=4x and 4*4=16. Now you still have the subtraction sign so your answer will be 4x-16.

Step-by-step explanation:

(a) 7x = 56

divide through by 7

x= 8

(b) 4n = 48

divide through by 4

n = 12

(b) 5c = 80

divide through by 5

n = 16

Answer:

a. 8

b. 12

c.  16

Step-by-step explanation:

7x= 56

You have to get x alone so divide

Divide by 7 to get answer (whatever you do to one side, do to the other)

x= 8

EDIT:

4a. 7x=56

7x/7 = 56/7

x= 8

4b. 4x=48

4x/4=48/4

x= 12

4c. 5c= 80

5c/5=80/5

c=16

the same goes for the rest

p.s. pls practice your multiplication as you will need it throughout high school :)

Answer:

0.41 cm

Step-by-step explanation:

The scale on the map is 1 in 86 mi.

This means that, 1 cm on the map represents 86 miles in real life, or on earth.

Then we're told that in real life, a distance is 35 miles, and how far they are on the map.

If 1 cm equals 86 miles, then we can say that x cm equals 35 miles

1 cm ----> 86

x cm ----> 35

x * 86 = 35 * 1

x = 35 / 86

x = 0.41 cm

Therefore, they must be 0.41 cm farther or closer apart on the map scale.

Answer:

f(y) = 4y2 - 4v

f(y) = 4y² - 4(-4) = 4y² + 16

f(y) = 4y² - 4(-3) = 4y² + 12

f(y) = 4y² - 4(-2) =4y² + 8

This is a trapezoid. The formula for a trapezoid is Area = 1/2 (b1 + b2)* h/2

Givens

b1 = 11

b2 = 15

h = 4*√3

Solution

Area = 1/2 (15 + 11 )*4*√3

Area = 1/2(26)*4√4

Area = 13 * 4√3
