Answer:
23x^2
Step-by-step explanation:
When adding variables, if they have the same exponent then all that needs to be done is add the constants. In this case both have x^2 so the answer is 23x^2. Hope this helps! :)
Answer:
y=7.51
Step-by-step explanation:
First, you have to simplify one of the equations down
3x-y=4
y=-4+3x
Second, you insert the value of y into the other equation and then solve for x
9x+5(-4+3x)=8
9x-20+15x=8
24x=28
x=1.17
Last, insert the value of x into the original equation and then solve for y
y=4+3(1.17)
y=7.51
Answer:
(4,10)
Step-by-step explanation:
Input: (3,9)
(3+1, 9+1)
Output: (4,10)
19/20= 0.95
-1/8= -0.125
17/5= 3.4
HOPE THIS HELPS!
