PLEASE HELP DUE SOON

vaieri [72.5K]

Answer:

I got 7%

Step-by-step explanation:

110 x .15 = 16.5

110-16.5=93.5

93.5 x .10 = 9.35

93.5 + 9.35= $102.82

Thats the discount price

110 - 102.82 + 7.18

7.18/102 = .0698

.0698 x 100 = 6.98

I have this on my middle school test and it's my first time doing it so yea. I hope it helps even if it's already too late.

Find the gradients of lines A and B.

pishuonlain [190]

Answer:

Gradient of line A = 4

Gradient of line B = -2

Step-by-step explanation:

To solve this question, we will use the formula for gradient passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ ,

Gradient (m) = $\frac{y_2-y_1}{x_2-x_1}$

For line A,

Since, line A passes through (3, 6) and (4, 10)

Gradient of line A = $\frac{10-6}{4-3}$

= 4

For line B,

Since, line B passes through (1, 6) and (2, 4),

Gradient of line B = $\frac{6-4}{1-2}$

= -2
