Answer: slope is 5, (-2,3) is a solution
Step-by-step explanation:
Notice in y-3=5(x+2), y coefficient is +1 and x coefficient will be 5 no matter what happens with 5×2. So slope is 5.
Check (-2,-3), notice -2+2 is zero so right hand side is zero. Notice -3 - 3 is not zero, but 3-3 will be. So (-2,3) is a point on the line.
Y-int = 0
And the slope is 1
Answer:
On a coordinate plane, a triangle has points (negative 4, 3), (1, negative 2), (5, 3).
Step-by-step explanation:
This coordinate above gives us the best range of values
A. Kellie's minute-per-mile pace 9 minutes per mile.
To find this, divide her time (72 minutes) by the number of miles she went (8). 72 divided by 8 is 9 minutes per mile.
B. Ashley ran 4 miles in 34 minutes. First, divide Ashley's time (102 minutes) by the number of miles she went (12). 102 divided by 12 is 8.5 minutes per mile. Then divide 34 by 8.5 to get how far she went in that time. Thus meaning 4 miles.
C. The difference in time between their 4 miles is 2 minutes. Kellie took 36 minutes to go 4 mile (4 miles times 9 minutes is 36 minutes) and Ashley took 34 minutes to go 4 miles (as stated in part B.) Lastly, subtract 34 from 36 to get the 2 minute difference.
I hope this helps!
Answer:
2x-17
Step-by-step explanation:
-3(x + 5) + 5(x – 2) + 8
Lets begin:
What is -3(x+5)? I do -3×x+(-3)×5=-3x-15.
So 5(x-2) is 5×x+5×(-2)=5x-10.
Now lets sum it:
-3x-15+5x-10=2x-25
And we have 8:
2x-25+8=2x-17
