Answer:
3 points
Step-by-step explanation:
If you do the vertical line test, there are 3 points that need to be removed, as there can only be 1 x value for every y value in order for it to be a function.
As x = 5 & z=12,
<span>2/3 = y /(xz) = y/(5*12) </span>
<span>= y/60 </span>
<span>so y / 60 = 2/3 </span>
<span>y = (2*60)/3 </span>
<span>= 40</span>
Answer:
5. 76
6. 24
Step-by-step explanation:
5.
x + x = 152
2x = 152
x = 76
6.
2x + 3x = 120
5x = 120
x = 24
Answer:
Step-by-step explanation:
Given two similar triangles.
Corresponding parts of similar figures have same ratio.
<u>Use ratios to find the value of x:</u>
- (4x - 5)/(x + 7) = 35/12.5
- (4x - 5)/(x + 7) = 14/5
- 5(4x - 5) = 14(x + 7)
- 20x - 25 = 14x + 98
- 20x - 14x = 98 + 25
- 6x = 123
- x = 123/6
- x = 20.5
