Answer:
11. A) 12
12. D)11
Step-by-step explanation:
11. We substitute x with 12 in 3(x)-11.
3(12)-11=
36-11= 25
We substitute x with 12 for the second equation (x+13).
12+13=25
Both answers match so the answer for #11 is 12.
12.We substitute x with 11 in 4(x)-4.
4(11)-4=
44-4=40
We substitute x with 11 for the second equation (2(x)+18)
2(11)+18=
22+18=40
Both answers match so the answer for #12 is 11.

4x=-x+10
I’m confused?
Answer:
x=2
Step-by-step explanation:
4x=-x+10
To find x, we first add x to each side to get rid of -x on the right side.
5x=10
Then, we divide each side by 5 to get x by itself.
x=2
And that's your answer :)

Step-by-step explanation:
When y=x, then the line goes up 1 and right 1.
The points (2, 3) and (3, 6) fall on a particular line. What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=3x-3
Step-by-step explanation:
insert the first point into y=mx+b
3=2m+b
----------------
Do it again with the other point
6=3m+b
-------------
Now put both equations in a system of equations
3=2m+b
6=3m+b
solve for m and b
m=3 and b=-3
y=3x-3
m=slope
b=y-intercept

Can someone help me out with this question as I’m completely stuck
Answer:
Step-by-step explanation:
∠BEF = ∠ABE {Alternate interior angle}
∠BEF = 60
∠EQR = ∠ BEF {Corresponding angles}
∠EQR = 60
In ΔEQR
∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}
80 + 60 +x = 180
140 + x = 180
x = 180- 140
x = 40

subtract 12a² + 15ab - 20b² from 15a² + 10ab + 8b²
help.
Answer:
3a^2 + 28b^2 - 5ab
Step-by-step explanation:
here's your solution
=> to subtract (12x^2 + 15ab - 29b^2) from
( 15a^2 + 10ab + 8b^2)
=> (15a^2 + 10ab + 8b^2) - (12a^2 + 15ab - 20b^2)
=> 15a^2 + 10ab + 8b^2 - 12a^2 - 15ab + 20b^2
=> 15a^2 - 12a^2 + 8b^2 + 20b^2 + 10ab - 15ab
=> 3a^2 + 28b^2 - 5ab
