Answer:
y = -3x-5
Step-by-step explanation:
The equation for a slope is y = mx + b.
m = slope (in this case -3)
b = y-intercept (in this case -5)
The question is incomplete:
Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?
Answer:
$24
Step-by-step explanation:
From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:
x+0.05x=25.20
Then, you can isolate x to find the price before tax:
1.05x=25.20
x=25.20/1.05
x= 24
According to this, the price before tax of the food items is $24.
2x + y = 71
y = x + 5
2x + (x + 5) = 71
3x + 5 = 71
3x = 71 - 5
3x = 66
x = 66/3
x = 22 .... small van
y = x + 5
y = 22 + 5
y = 27 <=== larger van
