Answer:
28
Step-by-step explanation:
Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:
28x + 24y = 1,188
28x + 13y = 836
So since the number before the x is the same in both equations, we are going to want to cancel that out.
28x + 24y = 1,188
-1(28x + 13y = 836)
----------------
28x + 24y = 1,188
-28x - 13y = -836
Add the two equations together! There will be no x value :)
11y = 352
y = 32... The deluxe basket is going to cost $32
Put the y value into one of the equations to solve for x.
28x + 13(32) = 836
28x + 416 = 836
28x = 420
x = 15... The regular basket will cost $15
Hope this helps!
Answer:
7 whole pieces
Step-by-step explanation:
There is 11.5 inches of rope.
Length of a piece = 1.5 inches
No . of pieces = total / unit length
= 11.5 / 1.5
= 7.667
There will be 7 whole pieces
To find the line using (5,3) (8,-2) Use x1y1 over x2y2
Answer:
It is increasing in the interval (-∞, 3/2).
Step-by-step explanation:
y = -x^2 + 3x + 8
The derivative is:
dy/dx = -2x + 3
This is the slope of tangent to the curve so when f(x) is increasing
-2x + 3 > 0
-2x > - 3
x < 3/2
So it is increasing in the interval (-∞, 3/2)
