Answer:

-2

Step-by-step explanation:

replace x with -4 in the h(x) function

h(x) = -2x-10 ➡ h(-4) = (-2)×(-4)-10 ➡8-10 = -2

Answer: -2

Step-by-step explanation:

so the original equation is

h(x) = -2x – 10,

but now we know that x =(-4).

so if we plug that into wherever there's an X we get

h(-4) = -2 x -4 – 10

so now we can solve, which is pretty easy

-2 x -4= 8

8 + -10 = -2

And voila we have the our answer -2

very easy

Brownies are now on sale. Each brownie costs $0.20 less than the original price. Right now, if you buy 8 of them it will cost $1

Airida [17]

Answer: The original price of brownie was $2.1 each.

Step-by-step explanation:

since we have given that

Let the original price will be x

Number of brownie purchased = 8

According to question , each brownie costs $0.20 less than the original price.

So, it becomes

$8\times (x-0.20)=\$15.20\\\\8x-1.6=15.20\\\\8x=15.20+1.60\\\\8x=16.8\\\\x=\frac{16.8}{8}\\\\x=\$2.1$

Hence, the original price of brownie was $2.1 each.

An investor plans to invest $500 a year and expects to get a 10.5% return. If the investor makes these contributions at the end

taurus [48]

The present value of the investment is $6000.

According to the statement

Principal amount = $500

and Return amount = 10.5%

Time period = 20 years.

Now we find the present value of money then

By the formula

PV = P[1-(1+r)^n]/r

PV = 500[1-(1+0.10)^20]/0.10

PV = 6000

So, The present value of the investment is $6000.

How can you change the equation y = 2x + 3 to function notation?

qwelly [4]

Answer:

$f(x)=2x+3$

Step-by-step explanation:

The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for $f(x)$

That is all. This would mean that the function notation for the equation would be: $f(x)=2x+3$
