It'd take you<span>, 1 minute and 33 secounds.
45 miles = 60 minutes
1 mile = 60/45 = 4/3 = 1.33 minutes </span>
Answer:
Step-by-step explanation:
y - 7 = -5/2(x - 2)
y - 7 = -5/2x + 5
y = -5/2x + 12
C = 5/9(F - 32)...multiply both sides by 9/5, eliminating the 5/9 on the right
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F <===
Alright, denote sweatshirts by x and tshirts by y:
for billy: 2x+3y=35$
for jordan:3x+3y=45$
We need to get rid of one of the unknowns inorder to solve, therefore we will subtract the two equations from each other. This will get rid of the y variable(3y-3y=0)
2x+3y=35$
-
3x+3y=45$
=
-1x=-10$
we get rid of the negative, which leaves us with x=10$. Knowing this info, we can now easily calculate y:
2x+3y=35$
2(10)+3y=35$
20+3y=35$
3y=15
y=15/3
y=5
Hope this helps!
Answer:
y = -2x + 4
Step-by-step explanation:
First find slope:
We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:
y = -2x + b
The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:
y = -2x + 4
