Answer:
The width measures 2.5 cm
Step-by-step explanation:
Area of triangle = Area of rectangle
1/2 bh = wh
1/2(5)(6) = w(6)
1/2(30) = 6w
15 = 6w
15 ÷ 6 = w
2.5 = w
Step-by-step explanation:
T = 55 + 6w

Part A: Yes this is a function because there are no repeated x values. Each x value points to exactly one y output. You can graph each point and the graph will not fail the vertical line test.

Part B: Plug x = 6 into the f(x) function given to get
f(x) = 7x-15
f(6) = 7*6-15
f(6) = 42-15
f(6) = 27
Now compare this with the table. According to the table, when x = 6, the value of y is 14. So the f(x) value is larger than the table value when x = 6
----------------------------------------------
Part C:
Replace f(x) with 6 and solve for x
f(x) = 7x-15
6 = 7x-15
6+15 = 7x-15+15
21 = 7x
7x = 21
7x/7 = 21/7
x = 3
So the final answer, for part C, is x = 3
Answer:
405 yards
Step-by-step explanation:
Given that,
A company made 1,215 yards of copper wire.
They want to wrap the same amount of wire on each three poles.
3 poles = 1,215 yards of copper wire
1 pole = 405 yards of copper wire
So, each pole will require 405 yards of copper wire.
Y-3=4/11(x-11). Doing a problem like this is mostly memorizing point slope formula, by knowing y-y2=m(x-x1) you can just "plug" in 3 as your y1 and 11 as your x1 then finally 4/11 as your slope being y-3=4/11(x-11)
