If f(x)=2x^2-10, find f(-3)
Maurinko [17]

Answer:

f(- 3) = 8

Step-by-step explanation:

To evaluate f(- 3), substitute x = - 3 into f(x) , that is

f(- 3) = 2(- 3)² - 10 = 2(9) - 10 = 18 - 10 = 8

How do I multiply this?
Novay_Z [31]
Oh my goodness . . .

What do you get when you multiply a number by itself ?
Do you get the square of the number ?

And what do you get when you square the square root of a number ?
Is it the number inside the square root ?

For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
                                                   √Q times √Q .
Isn't that just ' Q ' ?

And is this enough help ?

7. The Big Screamer Coaster carries 92 people altogether. Some of its cars carry 4 passengers and the rest carry 6 passengers. T
inna [77]

Answer:

There are 11 four person passengar cars

Step-by-step explanation:

let's call the number of four person cars A , & the number of six person cars B

there are 3 less 6 person cars than 4 people cars which can be written as:

A - 3 = B

there are also 92 total people that can go on max on the whole ride which can be written as:

4A + 6B = 92

Now we need to subsitute in our first equation into the second, so:

4A + 6(A-3) = 92

then distrbute the 6:

4A + 6A - 18 = 92

bring like terms to the same side & consolidate:

4A + 6A = 92 + 18

10A = 110

divide the right by # of A to get a single term :

A = 110/10

A= 11

Answer:

$146.625

Further explanation

Given:

At a factory, a mechanic earns $17.25 an hour.

The president of the company earns 6³/₄ times as much for each hour he works.

The janitor at the same company earns ³/₄ as much as the mechanic.

Question:

How much does the company pay for all three people employees' wages for one hour of work?

The Process:

Let us prepare a model for a mechanic earns $17.25 an hour.

Let us do multiplication on a fraction at first.

Then we make a model for the president of the company who earn 6³/₄ (six and three quarter) times as much for each hour the mechanic works. Recall that

Let's calculate how much the president of the company earns for each hour.

And we also calculate for the janitors who earn ³/₄ as much as the mechanic.

Finally, let's add up all earning to find out how much does the company pay for all three people employees' wages for one hour of work.
