Answer:
16.5
Step-by-step explanation:
Just put in the values of C and y first into the expression.
C = 4x + 5y
Put in values.
51 = 4x + 5(-3)
Evaluate.
51 = 4x + (-15)
Swap positions.
4x + (-15) = 51
Shift (-15) to the other side and change to (+15).
4x = 51 + 15
= 66
Find x.
x = 66 ÷ 4
x = 16.5
Answer:
b) EF = GF , as both of them are at equal distance from the center
Step-by-step explanation:
Here we are given a ΔEFG inscribed in a circle. We have to determine whether EF = Gf and why ?
Here we see that the center is A
And EF and GF forms the chords of this circle.
The distance of these chords from the center is given as AD and DH . It is also given that both are equal.
The property of a circle says that
When chords are drawn at equal distance from the center , the chords are equal to each other. Hence we have EF and GF equal to each other.
Answer:
B
Step-by-step explanation:
The answer would be B, because the y-intercept is positive. To double check I used an online graphing calculator and it is correct.
