45/35＝54/54－x
9/7＝54/54－x
9(54－x)＝378
54－x＝42
x＝12
Hope my answer helped u :)
The answer is the 5th one
Slope=(59-83)/(4-6)=12
equation of the line:
(y-59)/(x-4)=12
y-59=12x-48
y=12x+11
put x=0, y=11
so the y-intercept is 11
Answer:
r=2
Step-by-step explanation:
y = k x^r is the formula for a direct variation
y = k x^ -r is the formula for a indirect variation
20= 5 (1/2)^ -r
Divide each side by 5
4 = (1/2) ^ -r
Rewriting
2^2 = 2^ -1 ^ -r
2^2 = 2 ^ r
The bases are the same so
2 =r
Answer:
2x² = -8
x² = -4
The answer is no real solutions (x ∉ R) because a perfect square cannot be negative.
