Let f(x)=4x^2+13x-12 and g(x)=x+4. Perform the function operation
F•g(x)
Please help!!!
Answer: 4x³+29x²+40x-48
Step-by-step explanation:
To solve f(x)·g(x), you multiply them together.
(4x²+13x-12)(x+4) [distribute by FOIL]
4x³+16x²+13x²+52x-12x-48 [combine like terms]
4x³+29x²+40x-48
Now, we know that f(x)·g(x)=4x³+29x²+40x-48.
Answer: 4x³+29x²+40x-48
Step-by-step explanation:
The product of two functions=f(x)·g(x)=fg(x)
Use FOIL method to simplify expression.
FirstOuterInner Laterf(x)·g(x)
=(4x²+13x-12)·(x+4)
=4x³+16x²+13x²+52x-12x-48

The sum of five consecutive integers is five. What is the product of the five integers?
Answer:Let n = the smallest integer
Then the other integers are n+1, n+2, n+3 and n+4
Sum = n + n+1 + n+2 + n+3 + n+4 = 5n + 10 = 5(n + 2)
So the sum is always divisible by 5, for any value of n

There are $1.95 worth of nickels and quarters in a piggy bank there are three more nickels than quarters how many of each are in the piggy bank write how you got the answer please
Answer:
6 quarters and 9 nickels
Step-by-step explanation:
alright so this took me like an hour or two to figure out cause I'm stubborn. but I wanted to give an in depth answer
..
1) first we need to know how to write it.
___=___+___
1.95 is the full value of all of the coins so it goes here. (___)=___+___
1.95=___+___
We will use q for number of quarters and n for number of nickels. the value of a quarter .25 and the value of a nickel is .05. put the value of a quarter here. ___=(___)+___
1.95=.25q+___
we will put the value of the nickel here ___=___+(___)
1.95=.25q+.05n
now that we know how to write it, we can move onto step two.
2) figuring out what variable n is
n=___
Since we know that there are three more nickels than quarters, we can start to solve this equation.
n=q+3
3) change (n) to (q+3). dont forget to use parenthesis!
1.95=.25q+.05(q+3)
4) i forget what its called but multiply .05 throughout your parenthesis. ill show you.
1.95=.25q+.05(q+3)
.05*q= .05q and .05*3=.15
1.95=.25q+.05q+.15
5) add variables together.
1.95=.30q+.15
6) subtract .15 from both sides to get rid of it.
1.95=.30q+.15
-.15 -.15
1.80=.30q
7) divide .30 from both sides to isolate the q and get the answer of quarters
1.80=.30q
/.30 /.30
6=q
8) add three to the number of quarters to get the number of nickels.
6+3=9 nickels
Here we need to create and solve a system of equations to find the number of coins in the piggy bank.
We will see that there are 6 quarters and 9 nickels.
let's define the variables:
x = number of nickels in the piggy bank
y = number of quarters in the piggy bank.
Knowing that the total value of the coins in the piggy bank is $1.95, then we have:
x*$0.05 + y*$0.25 = $1.95
We also know that there are 3 more nickels than quarters, then we also have:
x = y + 3
Then the system of equations is:
x*$0.05 + y*$0.25 = $1.95
x = y + 3
To solve this, we can see that x is isolated in the second equation, so we can replace it in the other equation to get:
(y + 3)*$0.05 + y*$0.25 = $1.95
Now we can solve this for y:
y*$0.05 + 3*$0.05 + y*$0.25 = $1.95
y*$0.30 + $0.15 = $1.95
y*$0.30 = $1.95 - $0.15 = $1.80
y = ($1.80)/($0.30) = 6
So we have 6 quarters.
Then the number of nickels is given by:
x = y + 3 = 6 + 3 = 9
x = 9
There are 9 nickels.

Answer:
Each boy will get an equal amount of 4 slices of pizza
Step-by-step explanation:
Think about multiplication 3 boys x amount of pizza for each boy=12
you would create an equation [tex]3*p=12[/tex] divide both sides by 3 12/3=4
each boy would get an equal amount of 4 slices out of the 12 sliced pizza
PLEASE HELP!!! 15 PTS FOR THIS!! (Please show work also) Convert y=3x-14 (slope intercept form) to standard form
Answer:
[tex]3x-y=14[/tex]
Step-by-step explanation:
To convert an equation into standard form, we want to get into the form [tex]ax + by = c[/tex].
If we have [tex]y=3x-14[/tex], our first step is to get the x term on the left side. We can do this by subtracting 3x from both sides.
[tex]-3x + y = -14[/tex]
I find it easier now to just divide both sides by -1, so that we have a more consistent equation.
[tex]3x - y = 14[/tex]

Umm I don’t understand this question
Step-by-step explanation:
Hey there!!
Given,
[tex] \frac{24}{28} [/tex]
We generally divide the fraction from smallest prime number if they are divisible and make it in a simplest form.
So, let's work with it.
[tex] = \frac{24}{28} [/tex]
Divide it by 2.
=[tex] \frac{12}{14} [/tex]
See, it's again divisible by 2, so again divide it by 2.
=[tex] \frac{6}{7} [/tex]
Now, here 6 can be divided by 2, 3 but 7 can't be divided, as it is a prime number.
So, the answer is option D.

What is a straight line?
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the graph,
The coordinate of point C is (5.5, -2.5)
The vertical line (V) and horizontal line (H) intersect at point C are:
x = 5.5 (Vertical line)
y = -2.5 (Horizontal line)
Thus, the vertical line (V) and horizontal line (H) intersect at point C are V: x = 5.5; H: y = –2.5 option (D) is correct.
