Step-by-step explanation:
2*5*9*x = 540
x = 540/90 = 54/9 = 6
option D
Answer:
-2.61803398875, -0.38196601125
or
(-3±√5)/2
Step-by-step explanation:
First, expand. (2x+3)² = 4x²+12x+9=5
4x²+12x+4 = 0
Quadratic equations take the form ax²+bx+c = 0
In this case,
a = 4
b = 12
c = 4
You can solve with the equation x=(-b±√b²-4ac)/2a
Plug in:
(-12±√144-64)/8
(-12±√80)/8
(-12±√2^4×5)/8
(-12±4√5)/8
(-3±√5)/2
Final answer x = (-3±√5)/2
If you want decimal form: -2.61803398875, -0.38196601125
So from 98 to 110.92 is just 12.92 extra bucks.
if we take 98 to be the 100%, what is 12.92 off of it in percentage?
Answer:
y = 250x + 1500
Step-by-step explanation:
Slope is 250
y-intercept = 3000 - 6 × slope
3000 - 1500 = 1500
