Answer:

ok the slope is -1/2

the points I used where (-6,-1) and (-2,-3)

the intercept of y is -4

the equation is 2y +x+8=0

Step-by-step explanation:

using the formula<u> </u><u>y2-</u><u> </u><u>y1</u><u> </u><u> </u><u> </u><u> </u> = m

X2-X1

where m is the gradient, the slope is found

the original equation is y=-1/2x-4

and so if x is zero ( to get the y intercept)

y=-4

using the formula y - y1= m( x -x1 )

, the equation is determined

The function c = 100 + 0.30m represents the cost c (in dollars) of renting a car after driving m miles. What would the cost be t
aleksley [76]

Answer:

c = $130

Step-by-step explanation:

Given:

c = 100 + 0.30m

Where,

c = cost of renting a car (in dollars)

m = number of miles driven (in miles)

If m = 100 miles

c = 100 + 0.30m

= 100 + 0.30(100)

= 100 + 30

= 130

c = $130

Tiffany sees this given dilation and claims that the scale factor is 2
Alenkinab [10]

Answer:

The scale factor is not 2

Step-by-step explanation:

Given

See attachment for the dilated triangles

Triangle ABC is dilated through center point O to form triangle A'B'C'.

From the attachment, we have:

OC = 2 i.e. the distance from the center point to C

and

OC' = 6 i.e. the distance from the center point to C'

The length of OC' is calculated using:

OC' = OC + CC'

OC' = 2 + 4

OC' = 6

The scale factor (k) is then calculated by dividing OC' by OC

k = \frac{OC'}{OC}

k = \frac{6}{2}

k = 3

Hence, Tiffany's claim is incorrect.

Please answer number 4 and 5
Anestetic [448]

Answer: 4=G 5=A

Step-by-step explanation:

4: since he has only 1 dime 2 nickels and 1 quarter he cant pull out 2 dimes since he doesn't have them, meaning G is not possible.

5: To solve you have to multiply 2 1/2 and 3 1/4, one way is by creating improper fractions and multiply that way. So you will get 5/2 x 13/4 which will give you 65/8. Simply to get 8 and 1/8
