Slope intercept is basically solve for y
y=mx+b
m=slope
b=yintercept
-3x-10y=7
add 3x to both sides
-10y=3x+7
divide both sides by -10
y=-3/10x-7/10
slope is -3/10
yintercept is -7/10 or at point (0,-7/10)
The unit rate is 3 apples per minute
Step-by-step explanation:
Unit rate will be calculated by dividing the total number of apples by the time
Given
Total number of apples = 15
Time = 5 min
So, The unit rate will be:

Hence,

Answer:
The expression is 100x + 50y ≤ 800.
Step-by-step explanation:
The hip hop DJ charge for $100 per hour. Let x be number of hours of hip hop :


For rap DJ, the charge is $50 per hour. Let y be the number of hours of rap :


Given that both DJs spend a maximum of $800. So the final expression is :

She would have to score atleast a 74 on the test for her average to be 78
