Answer:
y=-3/2x+7.5
Step-by-step explanation:
You need to find the slope by subtracting second point,(7,-3), from the first point, (5,0), you get the slope of -3/2.
you need to put it on a graph with that slope, place the original two points and you move the slope up the y-axis 7.5, making the y-intercept (7.5,0)
Answer:
the words are not that clear
<span>2x+3y=7
x-y=1
</span>2x+3y=7
x=1+y
2*(1+y)+3y=7
x=1+y
2+2y+3y=7
x=1+y
5y=5 |(:5)
x=1+y
y=1
x=2
CHECK:
2x+3y=7
x-y=1
2*2 + 3*1 = 7
x-y = 1
2-1 = 1
Answer:
DOMAIN: -5, 2, 3 ,4
RANGE: 1, 3, 3 , 5
FUNCTION: Yes
Step-by-step explanation:
Since there is one value of y for every value of x this is a function.
The domain is just the x value (first number) and the range is just the y value(second number).
The answer would be X =90
