Answer:
Unit rate: $15 per hour
ordered pair: (1 ,15)
Step-by-step explanation:
30 ÷ 2 = 15
45 ÷ 3 = 15
--------------------------------------------------------------------------------------------------------
they both have 15, which means the graph is proportional and the unit rate is $15 per hour
The algebraic expression would be that Quarters = 25 - W
What you want to do is cross multiply so you get 5(x+4)=7(3x+28) then you distrubute the 5 and then you distribute the 5 and the 7 to the number in the parentheses 5x+20=21x+196
subtract 5x on both sides to get 20=16x+196 then you subtract 196 on both sides to get -176=16x last what you want to do is divide 16 on both sides to get x=-11
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:
so the slope is
the answer is -2
good luck
