So we need to plug in y into our equation so our new equation is:
4x - 2(x+1.75) = 4
first lets distribute the 2 by multiplying the values inside the parentheses by 2
4x - 2x + 3.5 = 4
4x - 2x = 2x
so now our equation is 2x + 3.5 = 4
we need to get x by itself on one side of the parentheses so lets move the 3.5 by subtracting by 3.5 on both sides
2x + 3.5 = 2x
4 - 3.5 = .5
new equation: 2x = .5
now to get rid of this 2 (being multiplied by x) we simply have to do the opposite - divide by 2 on each side
2x/2 = x
.5/2 = .25
so our x value is equal to .25!

Answer:
No
Step-by-step explanation:
y^2 = x^2 + 5
Rewriting
y^2 - x^2 = 5
This is a hyperbola
We can use the vertical line test to show that it is not a function since a vertical line passes through more than one point.
I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
Think of 2 times 2
You would duplicate 2 two times
8 times 8 is 64
6 times 6 is 36
It’s kind of just adding an integer (any number) to the integer that is stated after it
