Answer:
One student costs $3.75
Step-by-step explanation:
Unit rate is how much it is for 1 item. In this case, we want to know the cost for 1 student.
$30/8 students ... if it is $30/8 students, you can divide by 8 to find out how much it is for one student.
$30/8 = $3.75
Answer:
The equation would be B) y = 5x + 17
Step-by-step explanation:
To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -1/5. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 5.
Now that we have this, we can use the point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 7 = 5(x + 2)
y - 7 = 5x + 10
y = 5x + 17
Answer:
y=-2x+1
Step-by-step explanation:
to find the slope use the formula (y2-y1)/(x2-x1)
-5-3= -8
3-(-1) = 4
-8/4 = -2
The answer is 34 hope this helps
