Answer:
y + 1 = 9 (x + 5)
Step-by-step explanation:
point slope form is
y - y1 = m (x - x1)
replace the y1 with the y point, the x with the x point, and m with the slope
y - (-1) = 9 (x - (-5) )
now simplify
y + 1 = 9 (x + 5)
if you need slope intercept, just simplify more
distribute the 9 to the x and 5
y + 1 = 9x + 45
and subtract the 1 from both sides
y = 9x + 44
Answer:
Step-by-step explanation:
what
Answer:
The frequency is 3 more than expected.
T = seconds
M = number of miles
M=T/5
T = 5M
T=5(2miles)
T=10 seconds
If you want the strip around the mat:
x=strip of mat
2(20+2x)+2(15+2x)=102
Distribute
40+4x+30+4x=102
Combine like terms
70+8x=102
Subtract 70
8x=32
Divide by 8
x=4
If you want the whole width of the mat:
w=15+x
w=15+2*4
w=23
