X=15
According to a therom what’s its name *not actual name any triangle divided by parallel lines are proportional so.
X/5=x-6/3
You cross multiply
3x=5x-30
Then solve
3x=5x-30
-5x -5x
-2x=-30
-2x/-2= -30/-2
x=15
Answer:
ohlkkkk
Step-by-step explanation:
but give your questions first
Does that mean solve for y? If so, here it is:
5x + 2y = 11.
Move the x term by subtracting.
2y = -5x + 11
Divide by 2.
y = -5/2x + 11/2
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (7, - 2 ), thus
y - (- 2) = - 3(x - 7) , that is
y + 2 = - 3(x - 7) → B
Answer:
Not a function.
Does not pass vertical line test.
B.
Step-by-step explanation:
Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.
We say if it passes then it is a function.
It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.
If a single vertical line that you draw touches more than once, then it isn't a function.
When I say draw, I don't mean you should physically do it, but more so imagine it.
Now this particular relation is not a function because I can find a vertical line that touches more than once. Take the vertical line x=5 for example.
It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.
