Step-by-step explanation:
Reduce = Deduct = Subtract
7y + 2y^2 - 7 - (3 - 4y)
distribute the negative sign outside 3-4y.
7y+2y^2-7 - 3 + 4y
collect like terms, meaning try to make similar components of the equation together at one place.
7y & 4y are like terms in this case.
7y + 4y + 2y^2 - 7 - 3
11y + 2y^2 - 10
rewrite 2y^2 infront of the equation because it has the highest degree which is 2.
2y^2 + 11y - 10

Answer:
BC 4 in
Step-by-step explanation:
The steps for construction;
- Using a ruler draw line AB 4 inches and label the end points A and B
- At point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inches
- Mark that point C.
- Using the ruler, join point C and B and measure BC.
From calculation, length BC can be found by the formula;
------where a=b=4 in , cos A = cos 60°

BC = 4 in
Both are solid lines so its neither B or D
It is C because The first inequality in A would shade down when the graph shades up
