Answer:
Multiply 500 by 0.30
Step-by-step explanation:
30% = 0.30 In Decimal Form
Multiply
500x0.30=150
150 Is 30% Of 500
Answer:
-4 =x
Step-by-step explanation:
2x - 5= 5x + 7
Subtract 2x from each side
2x-2x - 5= 5x-2x + 7
-5 = 3x+7
Subtract 7 from each side
-5-7 = 3x+7-7
-12 = 3x
Divide by 3
-12/3 = 3x/3
-4 =x
Answer:
y= -3.5x +10
Step-by-step explanation:
The first thing to do in this equation is solve for m, the slope of the line.
Because we are given that the y-intercept is 10, we know that the graph intercepts at the point (0,10).
We are also given the point (5,-7.5).
Using the two points we can solve for the slope!
To solve for the slope use this formula:
(-7.5 -10) / (5 -0)
= -3.5
So our slope, m = -3.5
The other missing value is b, but is very easy to find.
In this example, b is equal to the y-intercept, so b=10.
Now we can plug in the values we found into the original equation
y =mx+b
y= -3.5x +10
