Answer:
3/2
Step-by-step explanation:
We can use the slope formula to find the slope of the line
m = ( y2-y1)/(x2-x1)
Using the points (0,-4) and (2,-1)
m = ( -1 - -4)/( 2 - 0)
= (-1+4)/ (2 -0)
= 3/2
Answer:
3
Step-by-step explanation:
You know that angle Y is a right angle because XY is the radius and YZ is a tangent to the circle. So, you can use the pythagorean theorem to find the third side:
XY^2+4^2=5^2
XY^2+16=25
XY^2=9
XY=3

The solution is -5/4= -1 1/4
Only the last equation is vertex form
Answer:
B
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides )
± 
= x
Change y back into terms of x, thus
(x) = ±
