Answer:
use desmos to figure it out.
Answer:
m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)
So it's just the matter of isolating m. Subtract m from both sides:
-9 = -2/5 m
Now you just need to multiply both sides by -5/2 to get your final answer.
Step-by-step explanation:
You would have to use multiplication to do this problem.
The number setence would be : 11,220 x 10
The answer would be: 112,200
(X+5)²=4/4
X+5=1, X+5=-1
X=1-5 X=-1-5
X=-4 X=-6
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
