g(m) = -2n/9

explanation:

make "m" the subject.

solve:

-2m - 5n = 7m - 3n

-2m - 7m = -3n + 5n

-9m = 2n

m = -2n/9

Answer:

Option D

Step-by-step explanation:

Given the following question:

[tex]12 \frac{3}{4} \times3[/tex]

In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.

[tex]12 \frac{3}{4} \times3[/tex]
[tex]12\frac{3}{4} =4\times12=48+3=51=\frac{51}{4}[/tex]
[tex]3=\frac{3}{1}[/tex]
[tex]\frac{51}{4} \times\frac{3}{1}[/tex]
[tex]51\times3=153[/tex]
[tex]4\times1=4[/tex]
[tex]=\frac{153}{4}[/tex]

Convert the improper fraction back into a mixed number:

[tex]\frac{153}{4}[/tex]
[tex]\frac{153}{4} =153\div4=38\frac{1}{4}[/tex]
[tex]=38\frac{1}{4}[/tex]

Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.

Answer:

24

Step-by-step explanation:

You are basically inserting -4 into the function as x. It would be (-4)^2-2(-4) You can simplify it into 16 - (-8) or 24.

Answer:

24

Step-by-step explanation:

Well, f(-4) is the case in the formula when x=-4.

On that occasion, f(-4)=(-4)^2-2*(-4)=16+8=24

Using simple interest, it is found that the monthly payment for this loan is of $325.485.

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

[tex]A(t) = A(0)(1 + rt)[/tex]

In which:

In this problem, the parameters are A(0) = 8100, r = 0.0822, t = 2.5, hence, the total amount is:

[tex]A(t) = A(0)(1 + rt)[/tex]

[tex]A(t) = 8100[1 + 0.0822(2.5)][/tex]

[tex]A(t) = 9764.55[/tex]

it will be paid over 2.5 x 12 = 30 months, hence the monthly payment is given by:

M = 9764.55/30 = $325.485.

Answer:

18 squared + 24 squared = x squared

Step-by-step explanation:

As we know from Pythagorean theorem:

a^2=b^2+c^2, where a -s hypotenuse and b&c are adjacent sides of right angle.

Here we should have: x^2=18^+24^2

The interest that Niki paid in total will b A $39,695.48

We will use the formula of amount for two monthly compounded

[tex]A=\dfrac{P(1-(1+\dfrac{r}{t}^{-nt} )}{\dfrac{r}{t} }[/tex]

P is the periodic payment.

Here, A = $61,60

r = 0.0984

t = 6

n = 11 years  

By putting values in the formula we get,

[tex]61600=\dfrac{P(1-(1+\dfrac{0.0984}{6} ^{-11\times6} )}{\dfrac{0.0984}{6} }[/tex]

[tex]61600=\dfrac{P(1-(1+0.0164)^{-66}}{0.0164}[/tex]

[tex]1010.24=P(1-0.341769)[/tex]

[tex]1010.24=0.658231\times P[/tex]

[tex]P=$1534.78[/tex]

So, Niki pays $1534.78 every two months for eleven years.

Now the total payment made by Niki = [tex]11\times 6\times 1534.78=101295.48[/tex]

Hence, interest paid is = [tex]101295.48-61600=39695.48[/tex]

Thus interest that Niki paid in total will b A $39,695.48

Answer:

Step-by-step explanation:

The function A(n) = 22(1.1)^n-1 is an illustration of a geometric series

The sum of the 23rd through 40th terms of the series is 17.49

The nth term of the geometric series is given as:

[tex]A(n) = 22(1.1)^{n-1[/tex]

The nth term of a series is represented as:

[tex]A(n) = ar^{n-1[/tex]

So, by comparison;

We have:

[tex]a = 22[/tex]

[tex]r = 1.1[/tex]

The sum of nth term of a geometric progression is:

[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]

Start by calculating the sum of the first 22 terms

[tex]S_{22} = \frac{22(1.1^{22} - 1)}{22 - 1}[/tex]

[tex]S_{22} = \frac{157.086}{21}[/tex]

[tex]S_{22} = 7.48[/tex]

Next, calculate the sum of the first 40 terms

[tex]S_{40} = \frac{22(1.1^{40} - 1)}{40 - 1}[/tex]

[tex]S_{40} = \frac{973.70}{39}[/tex]

[tex]S_{40} = 24.97[/tex]

Subtract S22 from S40

[tex]S_{40} - S_{22} = 24.97 - 7.48[/tex]

[tex]S_{40} - S_{22} = 17.49[/tex]

Hence, the sum of the 23rd through 40th terms of the series is 17.49

In order to subtract these fractions, we should turn the first fraction into an improper fraction.

What is an improper fraction?

An improper fraction is a fraction whose numerator is greater than its denominator.

How to turn a mixed number into an improper fraction?

      - Multiply 1 times 8

    2. Add the numerator.

     - Add 7 to the product of 1 and 8 (which, of course, is equal to 8)

  8+7=15

Therefore, we have

[tex]\bold{\displaystyle\frac{15}{8} -\frac{3}{8}}[/tex]

Now all we have to do is subtract the numerators!

Yes, solutions, roots, x-intercepts, and zeros are the same thing.

The general quadratic equation is given by:

a*x^2 + b*x + c = 0

So the solutions are the values of x such that the above thing is zero.

On another hand, a parabola or a quadratic function is given by:

a*x^2 + b*x + c = y

The roots, zeros, or x-intercepts (these represent the same thing) are given by:

a*x^2 + b*x + c = 0

So these are the values of x such that the function becomes equal to zero, so these are exactly the same thing as the solutions of a quadratic equation.

Concluding, yes, solutions, roots, x-intercepts, and zeros are the same thing.

The slopes of both equations are identical (both being 2/3), therefore the only possible answers would be "infinitely many solutions" and "no solution". Because of the fact that the y-intercepts of the equations are different (-10 and 10) they two lines will never cross, meaning there is no solution.
