Answer:
- 2/5x=7/20x+1/4
- -3/4=-1/20x-1/2
- -3/4+1/20x=-1/2
Step-by-step explanation:
If you add 3/4 to both sides of the equation, you get ...
... 2/5x = 7/20x + 1/4 . . . . first choice
If you subtract 2/5x from both sides of the equation, you get ...
... -3/4 = -1/20x -1/2 . . . . third choice
If you subtract 7/20x from both sides of the equation, you get ...
... -3/4 +1/20x = -1/2 . . . . last choice
Choices 2 and 4 are erroneous versions of choices 1 and 3, so do not apply.
Answer: (12,0)
Steps:
First, put the equation in slope-intercept form.
y=mx+b
1.5x + 4.5y =18
Subtract 1.5x from both sides.
4.5y =-1.5x +18
Divide both sides by 4.5 to isolate y.
y = -1/3x + 4
Then replace y with 0 because the point for the x-intercept is exactly on the x-axis so the y=0.
0 = -1/3x + 4
Subtract 4 from both sides
-4 = -1/3x
Divide both sides by -1/3 to isolate the x
12=x

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.
Remember that for any relation, we have a set
that matches the the domain (also called the set of inputs) of the function and the set
that contains the range (also called the set of outputs).
Suppose our relation is:
![y=-10+x \\ \\ For \ x=1,2,3,4,5](https://tex.z-dn.net/?f=y%3D-10%2Bx%20%5C%5C%20%5C%5C%20For%20%5C%20x%3D1%2C2%2C3%2C4%2C5)
So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:
![\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5](https://tex.z-dn.net/?f=%5Ctext%7BIf%20x%3D1%7D%20%5C%5C%20%5C%5C%20y%3D-10%2B1%3D-9%20%5C%5C%20%5C%5C%20%5C%5C%20%5Ctext%7BIf%20x%3D2%7D%20%5C%5C%20%5C%5C%20y%3D-10%2B2%3D-8%20%5C%5C%20%5C%5C%20%5C%5C%20%5Ctext%7BIf%20x%3D3%7D%20%5C%5C%20%5C%5C%20y%3D-10%2B3%3D-7%20%5C%5C%20%5C%5C%20%5C%5C%20%5Ctext%7BIf%20x%3D4%7D%20%5C%5C%20%5C%5C%20y%3D-10%2B4%3D-6%20%5C%5C%20%5C%5C%20%5C%5C%20%5Ctext%7BIf%20x%3D5%7D%20%5C%5C%20%5C%5C%20y%3D-10%2B5%3D-5)
So in this context, the correct option is:
B) (-9,-8, -7, -6, -5}
