Answer:
y=3x+13
Step-by-step explanation:
y=mx+b
y=3x+b
so now we plug in the coordinates
1=3(-4)+b
1=-12+b
b=13
I think the answer would be 180
5*2=10 90*2=180
3/4 + 1/2
multiply 1/2 denominator and numerator by 2 to match 3/4
= 3/4 + 2/4 = 5/4 (copy same denominator add numerator)
2/6 + 1/3
divide 2/6 denominator and numerator by 2 to match 1/3
= 1/3 + 1/3 = 2/3 (copy same denominator add numerator)
5/9 + 2/3
multiply 2/3 denominator and numerator by 3 to match 5/9
= 5/9 + 6/9 = 11/9 (copy same denominator add numerator)
6/9 -1/5
cross multiply 6x5 - 1x9 for numerator
for denominator multiply 9x5
=30/45 - 9/45= 21/45
divide num and den by 3
=7/15
5/8-1/3
cross multiply 5x3-1x8 for numerator
multiply 8x3 for denominator
= 15/24 -8/24 =7/24
Answer:
9.8 < x < 10.2
Step-by-step explanation:
Given that:
Total amount = $25
Error = ±5
Let gallon of gas pumped = g
Price of regular gas = $2.50
Gallon of gas to be pumped = total amount / price per gallon
Gallon of gas = $25 / $2.50 = 10 gallons
Error = $0.5 / $2.5 = 0.2
(10 - 0.2) < x < (10 +. 0.2)
9.8 < x < 10.2
Answer:
678.00
