Answer:
No solution.
Explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x.
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
Answer: A
Step-by-step explanation:
1. Swap x and y.
2. Solve for the new y.
Add 8
Divide by 2.
Extract the square root.
Answer:
A, B, and D.
Step-by-step explanation:
HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:
5^2 = 5 x 5
aka, 25.
You can use this to check each of the answers in your formula, like this:
if x=6, then:
x^2 < 100
6 x 6 = 36
36 < 100
A is one of your correct answers!
Also remember, if you multiply a negative by a negative, it becomes positive.
-5 x -5 = 25
-10 x -10 = 100
