Once again it's (2a,0) I took this and got it right
Answer:
<u>Using below system of inequalities</u>
<u>Following the rules </u>
- 1. Finding x- and y - intercepts
- 2. Connecting with dotted line for each as no equal symbol present in any inequality
- 3. Shade respective regions
- 4. Solution is the intersection of the shades regions
- 5. Select any three points in the solution region
<u>Line 1</u>
- y > 2x - 3
- x- intercept: y = 0 ⇒ 0 = 2x - 3 ⇒ 2x = 3 ⇒ x = 1.5
- y - intercept: x = 0 ⇒ y = -3
- Shaded region is above the line (or to the left)
<u>Line 2</u>
- y < x + 1
- x- intercept: y = 0 ⇒ 0 = x + 1 ⇒ x = -1
- y - intercept: x = 0 ⇒ y = 1
- Shaded region is below the line (or to the right)
<u>Selected points are:</u>
W = total cost
W = $72.5 times number of people
W = 72.5n
Answer:
51:120
Step-by-step explanation:
since 120 is length in mm, it is the y value
since 50 is width in mm it is the x value
51mm:120mm
Answer: 7 spacers can be cut from the tube.
Solution:
Length of the tube: L=5 1/4 in=(5*4+1)/4 in=(20+1)/4 in→L=21/4 in
Number of spacers: n=?
Thickness of each spacer: t=3/4 in
n=L/t
n=(21/4 in) / (3/4 in)
n= (21/4) * (4/3)
n=(21*4) / (4*3)
n=84/12
n=7
