Just type it into the graphing calculator, but reorder and solve for y first.
x + y = 9
y = 9 - x
y = x^2
In the graphing calculator,
Y1 = 9 - x,
Y2 = x^2
If you don't have a graphing calculator try desmos.
Answer:
C.
Step-by-step explanation:
Range is the y-values. Since our max and min for y-values is 5 and -5, respectively, our answer is C.
Answer:
E: x = 13
F: x = 1.5 or 3/2
Step-by-step explanation:
This is for E:
x + 2/3 = 5
All you do is first multiply 5 * 3
and you will get 15
x + 2 = 15
Then you subtract from 15
15 - 2 = 13
So x = 13
This is for F:
10(x - 1) = 5
So all you do is distribute the 100 with x -1
10 * x = 100x
10 * -1 = 100
10x - 10 = 5
Then you add 10 to 15 because the number is -10
5 + 10 = 15
10x = 15
Now you divide by 10 on both sides
10x/10 = 15/10
10x/10 = x
15/10 = 3/2
So the answer for F is 3/2 or 1.5
Multiplying 5 to the first fraction we get 15/25+1/25=16/25
