Answer:
x = 2
Step-by-step explanation:
For secants that intersect at an external point, the product of the external length and total length is a constant.
... 3·(3 +5) = 4·(4 +x) . . . . . write the two products, and set them equal
... 24 = 16 +4x . . . . . . . . . . eliminate parentheses
... 8 = 4x . . . . . . . . . . . . . . .subtract 16
... 2 = x . . . . . . . . . . . . . . . . divide by 4
Answer:
15.6 MPG
Step-by-step explanation:
You start a trip when your odometer reads 23,672 miles, and you have a full tank of gas. After driving a few hours, you fill up your tank. If you buy 16.5 gallons and your odometer reads 23,927, how many miles to the gallon are you getting, rounded to the nearest tenth of a gallon.
You went 23,927 - 23,672 = 255 miles
Because you started on a full tank, you went 255 miles on 16.5 gallons
to figure MPG:
255/16.5 = 15.4545... MPG
rounded to nearest 10th of gallon:
15.6 MPG
Answer:
m=-3/5
Step-by-step explanation:
Simplifying
3x + 5y = 7
Solving
3x + 5y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
3x + 5y + -5y = 7 + -5y
Combine like terms: 5y + -5y = 0
3x + 0 = 7 + -5y
3x = 7 + -5y
Divide each side by '3'.
x = 2.333333333 + -1.666666667y
Simplifying
x = 2.333333333 + -1.666666667y
Answer:
First, this table is a function because it has no repeating input values
Second, it is increasing in both the x and y
third, since it is increasing in x and y it is a positive correlation( I dont know if you have learned that yet)
Fourth, the output increases by 4 each time the input increases by 1
