To find the distance b/t 2 points you need to use the distance formula. that is
distance = square root of (x2-x1)^2 + (y2-y1)^2
to fill it in, it is
(it doesnt matter which point you start with, as long as its consistent)
x1 = 9
x2 = 5
y1 = -8
y2 = -10
square root of (5-9)^2 + (-10-8)^2
lets do algebra!
square root of (-4)^2 + (-18)^2
square root of 16 + 324
square root of 340
Distance = 18.4391 units.
I hope this helps!

Answer:
graph g(x)=1/4 x^2 - 2
Step-by-step explanation:
You are to replace x with (1/2x) in the expression x^2-2
So you have (1/2x)^2-2
1/4 x^2-2
Graph some points for g(x)=1/4 x^2-2
The vertex is (0,-2) and the parabola is open up.
I would graph 2 more points besides the vertex
x | g(x) ordered pairs to graph
----------- (-1,-1.75) and (0,-2) and (1,-1.75)
-1 -1.75
0 -2
1 -1.75
Answer:
x = 3
y = -2
Step-by-step explanation:
x + 2y = -1
2x – 3y =12
Using substitution means that in one equation you solve for a variable. In this case, the first equation would be easier to solve for x since there are no coefficients.
x = -2y - 1
Now, we plug in the value of x into the second equation, and solve for y.
2 (-2y - 1) - 3y = 12
-4y - 2 - 3y = 12
-7y - 2 = 12
-7y = 14
y = -2
Since we have a numerical value of y, we can use it to solve for x by plugging it into one of the original equations.
x + 2(-2) = -1
x - 4 = - 1
x = 3
If you'd like to check the answer, plug in both values you got to the original equations!
I hope this helps!
