Answer:
so sorry ! but i need it
Step-by-step explanation:
(40+x)/2=60
40 +x = 120
x = 80
check :
40+80 = 120
120/2 = 60
so his second round needs to be 80 mph
Answer:
p = 1
Step-by-step explanation:
7 = 8 - p
7 + p = 8
p = 8-7
p = 1

Answer:
The same lines (answer)
Step-by-step explanation:
The equations can be written in slope-intercept form y = mx + c (where 'm' is slope and 'c' is the y-intecept) as,
y-3 = 2(x-3) .......(1) ; y + 5 = 2(x+1) ...........(2)
y = 2x - 6 + 3 ; y = 2x + 2 - 5
y = 2x -3 ; y = 2x - 3
Comparing with slope intercept form we have,
m1 = 2 ; m2 = 2
c1 = -3 ; c2 = -3
If the slopes are equal the lines are parallel and since y-intercepts are also equal means they are the same lines (overlapping)
(12x3 - 14x2 - 40x) / (2x-5)
Rewriting we have:
(2x (2x-5) (3x + 4)) / (2x-5)
We simplify similar terms:
2x * (3x + 4)
We rewrite:
6x2 + 8x
Answer:
The simplified expression is given in this case by:
6x2 + 8x
