m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction = StartFraction 63 minus 51 Over negative 2 minus (negative 4) EndFraction = StartFraction 12 Over negative 6 EndFraction = negative 2.
What did she do wrong?
She used the wrong formula for slope.
She used the wrong points to determine the slope.
She made a mistake when she subtracted x 1 from x 2.
She made a mistake when she subtracted y 1 from y 2.
Answer: she distributed the x values wrongly

A car is traveling at a rate of 50 miles per hour, while a motorcycle is traveling at 70 miles per hour. The car takes 4 hours longer to arrive at the destination. The equation representing the scenario is 50(x + 4) = 70x. What can be concluded about the equation? Check all that apply.
A The scenario is translated to car’s travel distance = motorcycle’s travel distance.
B The expression 70x represents the hours the motorcycle traveled.
C The expression (x + 4) represents the number of hours traveled by the car.
D The variable x represents the total hours driven by the motorcycle.
E The car’s travel distance is represented as 50(x + 4).

Answer:

Step-by-step explanation:
Answer:
x= 72.72 (with a line over it)
Step-by-step explanation:
(x - 5) + (1.4x) + (x) + (x + 35) = 360
Step 1. Simplify both sides of the equation.
x + 5 + 1.4x + x + x + 36 = 360
(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)
4.4x + 40 = 360
Step 2. Subtract 40 from both sides.
(4.4x + 40) - 40 = (360) - 40
4.4x = 320
Step 3. Divide both sides by 4.4
4.4x/4.4 = 320/4.4
x = 72.72 (72 repeats, so 72 with a line over it)

Step-by-step explanation:
1. Since your trying to get h by itself, divide both sides by lw.
2. You will know have lwh divided by lw and V divided by lw.
3. you cross out the lw next to the h because the division cancels it.
4. Now you have h=V/lw.

10/5 = x-6/x+3 Please show your work!
Answer:
-12
Step-by-step explanation:
10/5 = x-6/x+3
2/1 = x-6/x+3
cross multiply
2(x + 3) = x - 6
2x + 6 = x - 6
collect like terms
2x - x = -6 - 6
x = -12.

Tax to the 6.50$ once you get 7.25. You need to do 7.25. - 10.00 which would get you your change of 2.75$
