Answer:
5x+4y = 52
Step-by-step explanation:
We can first write the equation in point slope form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y - 8 = -5/4 ( x-4)
Multiply each side by 4 to get rid of the fraction
4(y - 8) = 4*(-5/4) ( x-4)
4(y - 8) = -5 ( x-4)
Distribute
4y - 32 = -5x+20
We want the equation in the form
Ax + By = C
Add 5x to each side
5x+4y -32 = -5x+5x+20
Add 32 to each side
5x+4y -32+32 =32+20
5x+4y = 52
Answer:
-11
Step-by-step explanation:
Plug in 0 for x and 3/5 for y into the expression
-4(0) + 5(3/5) - 14
Multiply the numbers inside the parentheses
0 + 3 - 14
3 - 14 = -11, which is your answer
3/8 mile in 3/5 hour
we want to find miles per hour or m/1h
convert 3/5 to 1 by multiplying it by 5/3
keep the fraction the same by multiply ing the whole thing by
to get
=
=5/8 miles per hour
Answer:
Step-by-step explanation:
-15 times -5 = 75
-15 + -5 = -20
