Answer:
She had 8/16 more.
Step-by-step explanation:
Take 9 and subtract 1 to get 8.
Answer: Each screensaver costs $2 and each Otterbox costs $7.
Step-by-step explanation:
Let x = Cost of each screensaver and y = cost of each Otterbox.
As per given, 4x+3y=29 (i)
6x +2y = 26 (ii)
Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get
9x+3y=39 (iii)
Eliminate (i) from (iii) , we get
5x = 10
⇒ x = 2 [Divide both sides by 5]
Put value of x in (i), we get
4(2)+3y=29
⇒ 8+3y= 29
⇒ 3y= 21
⇒ y =7 [Divide both sides by 7]
Hence, Each screensaver costs $2 and each Otterbox costs $7.

Step-by-step explanation:
Answer:
The equation is y = 4x + 19
Step-by-step explanation:
y = 4x - 6 Using y = mx + b, the slope = 4.
Parallel lines have the same slope.
Now substitute the slope = 4 and the given ordered pair (-5, -1) into the slope-intercept form and solve for b.
y = mx + b
-1 = 4(-5) + b
-1 = -20 + b
19 = b
Now substitute into y = mx + b m = 4 and b = 19
The equation is y = 4x + 19
