Step-by-step explanation:
your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda
<span>answer 1
Nancie is typing is represented by the equation
y = 35x
Therefore, the rate at which Nancie is typing is given by the slope of the straight line that in this case is:
35 words per minute
answer 2
To find the rate at which Suresh is typing we have to find the equation of the line with the data in the table.
For this case, the equation of the line will be given by:
y = 56x
Therefore, the rate at which Suresh is typing is given by the slope of the straight line which in this case is:
56 words per minute
answer 3
Nancie's rate = 35
Suresh's rate = 56
56-35 = 21 words per minute
Nancie's rate is 21words per minute less than Suresh's rate.

Answer:
40.5 ft
Step-by-step explanation:
Solve for the time at which the balls meet, then find the corresponding height.
__
The balls will meet at the height such that the two values of h are the same.
-16t^2 +56t = h = -16t^2 +156t -248
0 = 100t -248
t = 2.48
Using the first equation to find h, we have ...
h = t(-16t +56) = 2.48(-16·2.48 +56) = 40.4736
The balls meet at a height of about 40.5 feet.
(x−a)(x−b)
=(x+−a)(x+−b)
=(x)(x)+(x)(−b)+(−a)(x)+(−a)(−b)
=x2−bx−ax+ab

Answer:
-8 and -3
Step-by-step explanation:
Add 11x to both sides;
x + 3 = 0
Subtract 3 from both sides;
x = -3
x + 8 = 0
Subtract 8 from both sides;
x = -8
