46-(-26)
= 46+26
= 72
As - and - together makes plus.
Hope it helps you and please mark my answer as the brainliest
Y = -8 simply means for every x coordinate the y coordinate is -8, therefore it creates a horizontal line at y = -8.
X intercepts are when y = 0. Y intercepts are when x = 0.
In this case of the line, y = -8 there is no x intercept because y doesn’t equal 0.
However there is a y intercept at (0,-8) because y is -8 for every input including 0.

It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
