Answers

Answer 1
Answer: 2x - 6y + 3x² + 7y - 14y = 3x² + (2x - 14x) + (-6y + 7y) = 3x² - 12x + y

Just substitute..

y=3x for X

y=3(-1)

y=3(0)

y=3(1)

y=3(2)

y=3(3)

then what you get for y just plot it

Using a cardboard paper to construct and cut out two isosceles triangles. Join them base to base to form a single shape. What shape does it form?

Answers

Assume bases are same, the new shape you form will be kite (name of one type of quadrilateral)

It will be rhombus if both triangles are same.

Which set of values could be the side lengths of a 30-60-90 triangle? A. {4, 4 square root of 3, 8} B. {4, 4 square root of 2, 8 square root of 2} C. {4, 4 square root of 2, 8} D. {4, 4 square root of 3, 8 square root of 3}

Answers

Your answer is A.

When you have a 30-60-90 triangle, your sides will always have a set pattern. 

The side across from the 30 angle will be equal to n (in this case n = 4).

The side across from the 60 angle will always be equal to n√(3) (in this case, 4√(3)).

The side across from the 90 angle will always be 2n (in this case, 8).

You could go into trig or pythagorean theorem to prove this, but it's much simpler to remember it because it's a special triangle. 

So, you're answer is A.

Answer:

Your answer is going to be letter A

Evaluate 4a-bc if a=7 b=3 c= -2

Answers

Its 34 because 7x4=28, and 3 x -2 is -6 and a negative x - negative is positive so you would do 28+6 which is 34
You would plug in your answers and the equation would become 4(7)-(3*-2)=34. You should have known this if you are in high school.
