3x2 + 2x - 5 and -4 + 7x2

Answer:

(f × g)(x) = 3x^3 - 14x^2 -27x + 18

Step-by-step explanation:

That is f(x) × g(x). You have to multiply them as separate polynomials.

(f × g)(x) = (3x^2 + 4x - 3)(x - 6)

Use the foil method.

(f × g)(x) = 3x^3 - 18x^2 + 4x^2 - 24x - 3x + 18

Finally, simplify.

(f × g)(x) = 3x^3 - 14x^2 - 27x + 18

Answer:

The equation for the line that is shown is: Answer choice C.

[tex]y =\frac{1}{2}x+2[/tex]

Step-by-step explanation:

From what I can see, there is several clues that can lead us to our answer by just looking at the graph:

A. Your y - intercept is where your line crosses at a point on the y - axis, so your y - intercept is:

If you do not know, the y - intercept form in slope - intercept form is the 'b' value:

[tex]y = mx + b[/tex]

[tex]b =[/tex] y - intercept

[tex]mx =[/tex] slope (m is actually the letter that represents it, but thought I might include x in it to show you from the formula)

Now that you have found your 'b' value, you can eliminate several answer choices: Answer choice B. and D.

B. Now we will see if the slope is positive or negative.

To find out whether it is positive or negative, we would have to take a look at the direction of the line, in this case, the line is going upwards to the right, meaning the slope is positive.

C. Now to find the slope:

To do this we must know the fraction like form of a slope, this would be:

(m = slope)

To determine the slope, m, it is [tex]\frac{RISE}{RUN}[/tex]

'Rise' meaning the y point and 'run' being the x point

In this case:

the line rises up 1 and runs over 2

so, m = [tex]\frac{1}{2}[/tex]

Your final answer will be:

[tex]y =\frac{1}{2}x+2[/tex]

Answer:

2x = 1.6 as decimal

2x = 6/5 as fraction.

Step-by-step explanation:

Okay so just write it as an equation.

5x + 8 = 11 (minus 8 on both sides)

5x = 3 (divide by 5)

x = .6 or 3/5

NOW if you want to find what 2x equals. We already know what x equal so just multiply x by 2.

x = .6 (multiply by 2 on each side)

2x = 1.2 or

2x = 6/5

-$70

Step-by-step explanation:

Answer:

one solution

Step-by-step explanation:

Given

10x - 15 = 6x - 43 ( subtract 6x from both sides )

4x - 15 = - 43 ( add 15 to both sides )

4x = - 28 ( divide both sides by 4 )

x = - 7 ← one solution

Answer:

  4

Step-by-step explanation:

Any base raised to the power of 1 is that base.

  f(x) = 4^x

  f(1) = 4^1 = 4

Answer:

I think it is 4 (correct me if I'm wrong)

Step-by-step explanation:

the answer is 4 because the the f(1)

this means that the (x) is replaced by f(1)

then you see the 4^{x} is replaced by 4^{1}

4^{1} = 4

Answer:

Antoinette's parents paid $ 70000 by the time she left the school.

Step-by-step explanation:

Antoinette's parents paid at the beginning ([tex]t = 0[/tex]) $ 6230, and each year paid annual fees including increases seven times. ([tex]0 <t \leq 7[/tex]) We find that annual fee paid at a given year is represented by the following formula:

[tex]C(t) = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex]

Where:

[tex]C_{o}[/tex] - Initial annual fees, measured in US dollars.

[tex]C(t)[/tex] - Current annual fees, measured in US dollars.

[tex]r[/tex] - Yearly increase rate, dimensionless.

If we know that [tex]C_{o} = \$\,6230[/tex] and [tex]r =9.5[/tex], first 8 annual fees paid by Antoinette's parents are:

[tex]C(0) = \$\,6230[/tex]

[tex]C(1) =\$\,6821.85[/tex]

[tex]C(2) = \$\,7469.93[/tex]

[tex]C(3) = \$\,8179.57[/tex]

[tex]C(4) = \$\,8956.63[/tex]

[tex]C(5) = \$\,9807.51[/tex]

[tex]C(6) = \$\,10739.22[/tex]

[tex]C(7) = \$\,11759.45[/tex]

Now, we sum each yearly fees to determine the total paid by Antoinette's parents when she leaves the school at the end of the 8th year.

[tex]C_{T} = C(0) +C(1)+C(2) + C(3)+C(4)+C(5)+C(6)+C(7)[/tex]

[tex]C_{T} = \$\,6230+\$\,6821.85+\$\,7469.93+\$\,8179.57+\$\,8956.63+\$\,9807.51+\$\,10739.22+\$\,11759.45[/tex]

[tex]C_{T} = \$\,69964.16[/tex]

Antoinette's parents paid $ 70000 by the time she left the school.

Answer:

Try -6/7

Step-by-step explanation:

Answer:

B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.

Step-by-step explanation:

In order to find if a certain point exists on a line or not, we can simply substitute in the values, and see if the result is valid. Here we are given the point (4,-6), this means our x=4 and our y=-6. If this point lies on a line, then substituting in the values should result in a valid equation. Let's try the first one:

2x-y=14

2(4)-(-6)=14

8+6=14

14=14

This equation is valid which means the point (4,-6) is indeed a point on the first given line equation.

Now for the second one:

x-3y=22

(4)-3(-6)=22

4+18=22

22=22

This is also a valid equation meaning the point (4,-6) also exists on the second line equation. Since this point exists on both lines, they will intersect each other on a graph. Therefore the best answer here is B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.

Hope this helped!
