Answer:
x = 14.5°
Step-by-step explanation:
A+D = 180°
(8x-11) + (5y+2) = 180°
simplify:
5y + 8x = 189°
5y = 189 - 8x
D = B
(5y+2) = (4x+17)
simplify
5y = 4x + 15
then:
189 - 8x = 4x + 15
12x = 174
x = 14.5°
5y = 4(14.5) + 15
5y = 73
y = 14.6
check:
5(14.6) + 8(14.5) = 189
73 + 116 = 189
189 = 189
67 is 14.7% of 456. You take 67 times 100. Then divided it by 456
Answer:
f(8)=-2
Step-by-step explanation:
Let
x ----> the independent variable or input value
f(x) ---> the dependent variable or output value
we know that
f(8) ----> Is the value of the function f(x) when the value of x is equal to 8
<u><em>Verify each case</em></u>
1) (8,-2)
That means
For x=8
The value of the function is equal to -2
so
f(8)=-2
2) (-5,8)
That means
For x=-5
The value of the function is equal to 8
so
f(-5)=8
3) (5,3)
That means
For x=5
The value of the function is equal to 3
so
f(5)=3
