x=14 y=6
Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In this problem
Let
x------> the number of gallons
y------> the number of miles
the relationship between the number of miles and the gallons of gas represent a linear direct variation
The constant of proportionality k is equal to the slope m
therefore
the equation of the linear equation
#10. Sam: (4, 2); Theater: (-3, 5) #11. Sam is 3 km south and 7 km east of the
theater. #12. (-3, -4) #13. (-3, 0.5) #14. T (0.75, -1.0); U (0.75, 1.25); V (-0.75, 1.25) #15. W(-0.75, -1.0) #16. Janine is describing points that lie on the y-axis. Ordered pairs that lie on the x-axis have a y-coordinate of 0. The origin lies on the x- and y-axis. Any other point with an x-coordinate of 0 lies on the y-axis such as (0, 3).

Answer:
x=9
Step-by-step explanation:
First, distribute the 2 and each value in the parentheses.
2*x+2*5. This is the first half of the equation.
2*x+2*5= 3x+1 You can then simplify
2x+10=3x+1 Subtract 3x from both sides
(2x-3x)+10=(3x-3x[cancels out])+1
-x+10=1 Now subtract 10 from both sides
-x(10-10[cancels out to 0])=(1-10)
-x=-9 Since x is negative we need to solve for positive
x=9
Answer: y=-3/2x+3
Step-by-step explanation:
First subtract 3x from both sides to start isolating the y.
Then you get 2y=-3x+6
Divide both sides by 2 to get y alone and you get
y=-3/2x+3
