Write an equation for the following points. (1, 100) (2, 50) (4, 25), (5, 20)

A line has a slope of –9 and includes the points (–7,u) and (9,9).

The value of u is 153.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line has a slope of –9 and includes the points (–7,u) and (9,9).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

-9 = (9 - u)/(9 + 7)

-9 = (9- u)/16

9 - u = -144

u = 153.

Therefore, the value of u is 153.

The equation of the line of Kaya’s line in slope-intercept form is y = 15x  + 25.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given this, Kaya babysits to add money to her savings. She draws a graph to show how much she can earn by babysitting.

To calculate the equation of the line we at least need Two points on the line.

Two points on the graph (0, 25) and (5, 100) and also the y-intercept of the given line is 25(where x is 0)

From the general formula of the slope-intercept form of an equation:

y=mx+b,

where m is the slope

b is the y-intercept,

Since. m = (y - y')/ (x -x')

In our case m = (100 - 25)/5-0)

m = 75 /5

m = 15

and b = 25

Thus, the equation of a line:

y = 15x  + 25

Therefore, The equation of the line of Kaya’s line in slope-intercept form is y = 15x  + 25.

Answer: 2:5

Step-by-step explanation:

Given,

Number of sunfish = 12

Number of rainbow shiner = 30

To find,

The ratio of sunfish to rainbow shiner.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Ratio of sunfish to rainbow shiner :

= Number of sunfish : Number of rainbow shiner

= 12 : 30

= 6 : 15

= 2 : 5

(This ratio cannot be for the simplified so we will have to assume this as the final answer of this question.)

Hence, the ratio is 2:5

Answer:

2:5

Find the number both sides can be divided by in this case, it is 6. Diving both sides by a common number gives us 2 from 12 and 5 from 30.

Answer:

[tex]\displaystyle y=-\frac{3}{8}x+2[/tex]

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes. So, we must first determine our slope of the original equation by converting to slope-intercept form:

[tex]-8x+3y=-6\\3y=8x-6\\y=\frac{8}{3}x-2[/tex]

Hence, because the slope of the original line is 8/3, then the slope of the perpendicular line is -3/8. We are not done, however, as we need to account for the point that the perpendicular line passes through by solving for the new y-intercept:

[tex]y=-\frac{3}{8}x+b\\ \\8=-\frac{3}{8}(-16)+b\\\\8=6+b\\\\2=b[/tex]

Thus, the perpendicular line equation is [tex]y=-\frac{3}{8}x+2[/tex]. See below for a graph.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]-8x+3y=-6\implies 3y=8x-6\implies y=\cfrac{8x-6}{3} \\\\\\ y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{8}{3}}x-2\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ \cfrac{8}{3}} ~\hfill \stackrel{reciprocal}{\cfrac{3}{8}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{8} }}[/tex]

so we're really looking for the equation of a line whose slope is -3/8 and it passes through (-16 , 8)

[tex](\stackrel{x_1}{-16}~,~\stackrel{y_1}{8})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{3}{8} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{- \cfrac{3}{8}}(x-\stackrel{x_1}{(-16)}) \implies y -8= -\cfrac{3}{8} (x +16) \\\\\\ y-8=-\cfrac{3}{8}x-6\implies {\Large \begin{array}{llll} y=-\cfrac{3}{8}x+2 \end{array}}[/tex]

On solving the provided question, we can say that so, the Interest Rate to be paid will be as = 5.08%

Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.

Interest Rate =($ Paid in Interest / $ Amount borrowed) X (360 / borrowed period)

A. 9 students offer all three subjects.

B. The only possible value of m is 8.

A. We can use the Principle of Inclusion-Exclusion (PIE) to find the number of students who offer all three subjects.

Let's call the number of students who offer all three subjects "x".

The total number of students who offer Biology is 35, but we have to subtract the number of students who offer only Biology and Economics (12) and only Biology and Physics (7) to avoid counting them twice.

So, the number of students who offer Biology only is 35 - 12 - 7 + x = 16 + x.

Similarly, the number of students who offer Economics only is 28 - 12 - 5 + x = 11 + x.

And the number of students who offer Physics only is 15 - 7 - 5 + x = 3 + x.

The total number of students who offer at least one of the three subjects is 58, so:

16 + x + 11 + x + 3 + x = 58

30 + 3x = 58

3x = 28

x = 9

So, 9 students offer all three subjects.

B. In a regular polygon with (2m + 1) sides, each interior angle is equal to (2m + 1 - 2) * 180 / (2m + 1) = (2m - 1) * 180 / (2m + 1).

We know that this value is equal to 1440, so:

(2m - 1) * 180 / (2m + 1) = 1440

Expanding the right side:

2m - 1 = 1440 * (2m + 1) / 180

Dividing both sides by (2m + 1) and rearranging:

2m = 1440 * 2 / 180 + 1

2m = 16 + 1

m = 8.5

Since m must be a positive integer, the only possible value of m is 8.
