The given equation solved for A is A = (T + 5)/ B

<h3>Solving linear equation</h3>

From the question, we are to solve the given equation for A

To solve the equation for A, we will simply make A the subject of the equation

The given equation is

T = AB - 5

Solving for A

T = AB - 5

Add 5 to both sides of the equation

T + 5 = AB - 5 + 5

T + 5 = AB

Divide both sides of the equation by B

That is,

(T + 5)/B = AB/B

(T + 5)/B = A

∴ A = (T + 5)/ B

Hence, the given equation solved for A is A = (T + 5)/ B

<u>Answer:</u>

The present value of 10,000 if interest is paid at a rate of 6.2% compounded weekly for 8 years is 6097.56

<u>Explanation:</u>

We know that compound interest is given by

$A=P\left(1+\frac{r}{n}\right)^{n t}$

Where ,

Where A = final amount (which is given to be = 10000)

P = Principal amount (which is the present amount which we have to find)

r = interest rate = 6.2 = 0.062

n = no. of times interest applied per time period = it is given that the interest is applied weekly, so in one year there are 52 weeks so n = 52

t = time period = 8 years

Substituting the given values, we get

$10000=\mathrm{P}\left(1+\frac{6.2}{52}\right)^{52\times 8}$

P = 6097.5

We get, P = 6097.56 which is the present value of a sum of money

HELP I WILL GIVE 50 POINTS AND BRAINLIEST TO WHOEVER ANSWERS FIRST Graph y>1−3x.

AleksandrR [38]

Answer:

The last graph

Step-by-step explanation:

This is because when there is a greater than sign, the line on the graph is dotted and the shaded area is facing upwards. I try to remember that when there is a greater than sign or a greater than or equal to sign, the shaded area faces up towards the sky.

Hope this helps. Please inform me if my answer is wrong.

Fill in the table so it represents a linear function.

castortr0y [4]

Answer:

2; 5; 8

Step-by-step explanation:

To fill in the table, we need to generate an equation to represent the relationship between x and y.

First, find the slope using the two pairs given, (5, -1) and (25, 11):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{11 -(-1)}{25 - 5} = \frac{12}{20} = \frac{3}{5}$

m = ⅗.

Next, using the point-slope form, we can use a point/coordinate pair and the slope to derive an equation as follows.

$y - y_1 = m(x - x_1)$

Where,

$x_1 = 5, y_1 = -1$

m = ⅗.

Plug in the values

$y -(-1) = \frac{3}{5}(x - 5)$

$y + 1 = \frac{3}{5}(x - 5)$

$y + 1 = \frac{3x}{5} - 3$

Subtract 1 from both sides

$y + 1 - 1 = \frac{3x}{5} - 3 - 1$

$y = \frac{3x}{5} - 4$

Use the equation above to fill out the table by plugging each value of x into the equation to get the corresponding values of y for each x value.

✔️When x = 10:

$y = \frac{3x}{5} - 4$

$y = \frac{3(10)}{5} - 4 = 6 - 4$

$y = 2$

✔️When x = 15:

$y = \frac{3x}{5} - 4$

$y = \frac{3(15)}{5} - 4 = 9 - 4$

$y = 5$

✔️When x = 20:

$y = \frac{3x}{5} - 4$

$y = \frac{3(20)}{5} - 4 = 12 - 4$

$y = 8$

Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.

riadik2000 [5.3K]

<span>First of all to calculate the distance between two points we can use distance formula

d=Square Root [(x2-x1)^2 + (y2-y1)^2]

Now substitute the given points p(x1,y1) and q(x2,y2)in above distance formula

The values are X2=3, X1=8and Y2=8and Y1=2.

After Substituting the values

d=Square Root[(-5)^2+(6)^2]

d=Square Root(25+36]

d=Square Root[61]

d=7.8

7.8 is the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.</span>
