Simon charges an initial fee plus an hourly fee to repair TVs. The table below shows the amounts Simon charges for the first thr
Sedbober [7]

Answer:

Rate of change: 25

Initial value: 25

Equation: y = 25x + 25

Step-by-step explanation:

✔️hours = x

Fee = y

Rate of change (m) = ∆y/∆x

Rate of change (m) = 25/1 = 25

Rate of change (m) = 25

✔️Initial value = y-intercept (b).

To find the initial value, simply substitute (x, y) = (1, 50) and m = 25 into y = mx + b.

Thus:

50 = (25)(1) + b

50 = 25 + b

Subtract 25 from each side

50 - 25 = b

25 = b

b = 25

✔️To write an equation, substitute m = 25 and b = 25 into y = mx + b.

Thus:

y = 25x + 25

Super confused definitely need help on this
Marat540 [252]

Answer:

(x-5)(x+8)=x^2+3x-40

Step-by-step explanation:

So we have the expression:

(x-5)(x+8)

To multiply, distribute the left to the terms on the right:

=(x-5)(x)+(x-5)(8)

Distribute:

=(x^2-5x)+(8x-40)

Combine like terms:

=(x^2)+(-5x+8x)+(-40)

Simplify:

=x^2+3x-40

Therefore:

(x-5)(x+8)=x^2+3x-40

In 2007, there were 31 laptops
abruzzese [7]

Answer:

l=31+20(y-2007)

where l is the number of laptops, and y is the year.

in 2017: l=231

Step-by-step explanation:

I will define the variable x as the number of years that passed since 2007.

Since the school buys 20 lapts each year, after a number x of years, the school will have

20*x more laptops.

and thus, since the school starts with 31 laptops, the equation to model this situation is

l=31+20*x

where l is the number of laptops.

since x is the number of years that have passed since 2007, it can be represented like this:

x=y-2007

where y can be any year, so the equation to model the situation using the year:

l=31+20(y-2007)

and this way we can find the number of laptos at the end of 2017:

y=2017

and

l=31+20(y-2007)

l=31+20(2017-2007)\\l=31+20(10)\\l=31+200\\l=231

What is the answer for -|-5x(-7)|​
Airida [17]

Answer will be -35

Since in an absolute equation, the inside will all be positive. So get rid of the negatives. 5x7. Then, outside of the absolute sign, there is a negative sign. Since that is outside, you cannot turn it into positive. Now, the answer is -35.
