a_sh-v [17]

Answer:

Step-by-step explanation:

From the graph attached,

Coordinates of points A, C and D are,

A(-2, -7), C(-6, 7) and D(9, 2)

Slope of AD = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{-7-2}{-2-9}$

= $\frac{9}{11}$

Slope of CD = $\frac{7-2}{-6-9}$

= $-\frac{1}{3}$

Slope of AC = $\frac{7-(-7)}{-6-(-2)}$

= $-\frac{14}{4}$

= $-\frac{7}{2}$

Answer:

$675

Step-by-step explanation:

Let

x = original price of laptop

Discount = 10%

Actual price paid = x - 10% of x

= x - .10x

= .90x

Cost of mouse = $13.99

Total amount paid = $621.49

Total amount paid = actual cost of laptop + Cost of mouse

621.49 = .90x + 13.99

621.49 - 13.99 = .90x

607.5 = .90x

x = 607.5 / .90

= 675

Original cost of the laptop = $675

Vikki [24]

Wow OK so the first number I came to was 72 so that's
bagels 6x12=72
apples 8x9=72
cookies 12x6=72
juice boxes 9x8=72

72/4=18 so she could make their lunch for 18 days
