Answer:
1. x=60
2.x=5
3.x=8
4.x=10
Step-by-step explanation:
im assuming you want to find x value for each.
Answer:
y = 10
Step-by-step explanation:
4/5 y = 8
4/5 y * 5/4 = 8 * 5/4 multiply by reciprocal
y = 10
You would do 40/x=x/15, therefore you get x^2=600. to find x you find the square root of each side. Rounded to the nearest tenth, you get 24.5. If you put it in simplest radical form you should get 10 times the square root of 6
Since you know the value of "x", you can plug in the value for "x" in the equation.
[When an exponent is negative, you move it to the other side of the fraction to make the exponent positive.]
For example:
or 
or y³
x = -2
f(x) = 9x + 7
f(-2) = 9(-2) + 7 = -18 + 7 = -11
(idk if you should have it as a decimal or a fraction)
x = -1
f(x) = 9x + 7
f(-1) = 9(-1) + 7 = -9 + 7 = -2
x = 0
f(x) = 9x + 7
f(0) = 9(0) + 7 = 7
x = 1
f(x) = 9x + 7
f(1) = 9(1) + 7 = 9 + 7 = 16
x = 2
f(x) = 9x + 7
f(2) = 9(2) + 7 = 18 + 7 = 25
You need to determine the solution of f(x) = g(x)
Since you know f(x) = 9x + 7 and , you can plug in (9x + 7) for f(x), and (
) into g(x)
f(x) = g(x)
You can plug in each value of x into the equation
Your answer is x = 2 because when you plug in 2 for x in the equation, you get 25 = 25
Answer:
2
Step-by-step explanation:
Total number of cards = 65
<em>she makes the same number of cards everyday for 7 days</em>
Number of days = 7
Cards per day = 65 / 7 = The result is 9 with a remainder of 2.
This means, she makes 9 cards per day for 7 days. Then on the last day she is left with 2 cards to make.
