Grade 10 Midterm Review

Factoring

100

What value can be factored out of y=64x²-72x+88

(For a bonus 100 points, what is the result of y after factoring this value out)

We can factor out 8!

The final value would be y=8(8x²-9x+11)

Expanding

100

Expand:

7x(4xy²-5y+10)

28x²y²-35xy+70x

Analytic Geometry

100

What are the slopes of the parallel and perpendicular lines of y = 7/20x - 8 

Parallel: y = 7/20x

Perpendicular: y = -20/7x

200

What is the midpoint between A(7, -2) and B(-4, -8)

Mid_{AB =} (3/2, 3)

300

The length of the line segment AB with A(4, 7) and B(-3, -2) is?

Length_AB=SQRT(130)

Solving Linear Systems

y = (7/3)x +121

have?

0 Solutions!
