Answer:
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the amount of fuel in gallons
we know that
The linear equation in slope intercept form is equal to
where
m is the unit rate or slope
b is the y-intercept or initial value
we have that
The unit rate or slope is equal to
----> initial value (value of y when the value of x is equal to zero)
substitute
Answer:
4th option
Step-by-step explanation:
L = larger softball and S = smaller softball ,then
L + S = 80 → (1) ← equation based on number of softballs ordered
2.75L + 3.25S = 245 → (2) ← equation based on cost
subtract S from both sides in (1)
L = 80 - S → (3)
substitute L = 80 - S into (2)
2.75(80 - S) + 3.25S = 245 ← distribute parenthesis and simplify left side
220 - 2.75S + 3.25S = 245
220 + 0.5S = 245 ( subtract 220 from both sides )
0.5S = 25 ( divide both sides by 0.5 )
S = 50
substitute S = 50 into (3)
L = 80 - 50 = 30
50 small softballs and 30 large softballs were ordered
I think the answer is 1 for every 4
Answer: 1,38
Step-by-step explanation: Because 48,345 ÷ 34,886 = 1,385799461101875, so I rounded off to 1,38
Solve both equations 1/2x + 5y = 6 becomes y = -1/10x + 5/6 and 3x +30y = 36 becomes y = -1/10x + 36/30. Since both equations have the same slope..1/10 the lines are going to be parallel since the constant is different 5/6 vice 36/30. They will never cross.
