Answer:
10/11
Step-by-step explanation:
The fractions already have like denominators so you just add the numerators as there is no need to find the LCM but just in case
Answer:
y = - 3
Step-by-step explanation:
Locate x = 2 on the x- axis, then go down vertically to meet the line. At this point read off the corresponding value on the y- axis, thus
The value of the function at x = 2 is y = - 3
2(4+39) = 39 + 4 = 43
43 x 2 = 86
You need to get x= something.
To do this, you -4 on both sides to leave you with just an x value on the left. This gives -6x=-6
Then you need x on its own, so you divide both sides by -6.
-6/-6= 1, so x=1
