Answer:
4x_2y=5
4x=5+2y
x=5+2y/5
now, y=3x_1
putting value of x in second question
In this way you can do
You need to make a blank graph that goes from 1 to 10 in each direction and then just plot the points. sorry the picture is sideways idk how to fix it.
Answer:
see below
Step-by-step explanation:
h(x) = (x − 5)^2 − 7
This is in vertex form
y = a( x-h)^2 + k
where ( h,k) is the vertex and x=h is the axis of symmetry
( 5,-7) is the vertex and x=5 is the axis of symmetry
Answer:
A
Step-by-step explanation:
The only one you can eliminate on sight is C. You are going to get an x^3 somewhere along the line.
You can eliminate D on sight as well. The x^3 term is 12x^3 not 7x^3
Doesn't leave much does it?
(3x + 2)(4x^2 - 2x - 7)
3x: 12x^3 - 6x^2 - 21x
2 : 8x^2 - 4x - 14
======================= Add
12x^3 + 2x^2 - 25x - 14
Answer: A
