20% percent refers to the rate
So to find 20% off of $125 you have to multiply the rate by the original price and then subtract that number from the original price
First you have to make the percent into a decimal. To do that you have to move the decimal point over to the left two times or divide by 100:
20/100= .20
So the equation would be:
.20 • 125= 25
Now you have to subtract from the original number:
125-25=100
So the answer would be that the stereo would cost 100 with the 20% off sale
Answer:
B
Step-by-step explanation:
The answer is B because when you simplify it you get -3x + 10 = 0. Since this is no longer a quadratic equation, you can't solve it using the quadratic formula.
X² + 8x + 3 < 0
use the quadratic formula;
x = -8 + 2√13 / 2, -8 - 2√13 / 2
-4 - √13 < x < -4 + √13 (this is what they're asking as in interval notation)
hope this helps, God bless!
Answer:
h = 5
Step-by-step explanation:
One place to look to find the difference between f(x) and g(x) is the y-axis. The y-intercept of g(x) is 5. The y-intercept of f(x) is 0. Then you have ...
... g(0) = f(0) +h
... 5 = 0 +h . . . . put in the values you read from the graph
... 5 = h
