two quantities x and y are connected by the formula y=7_9x find the value of y when x=0​

A triangle contains three vertices, three sides, and three altitudes. The location where these three sides intersect is known as the orthocenter.

Every triangle has a different position for the orthocenter; for example, an equilateral triangle has the same orthocenter, circumcenter, incenter, and centroid, but other triangles will have a different position.

At Point M is at (1, 3) : The orthocenter is located inside an acute-angled triangle in this scenario.

At Point R is at (3, 9) : The orthocenter is located outside the triangle in the case of an obtuse-angled triangle.

At Point E is at (10, 2) : The orthocenter of a right-angled triangle is located at the right angle's apex.

A triangle is a basic three-sided polygon with three vertices. The "orthocenter of a triangle" is the intersection of a triangle's three altitudes, and it is typically depicted by the letter "H." A line segment drawn perpendicularly from each vertex to the opposite side of a triangle's opposing side is the triangle's height.

Non-linear relationships are those depicted by curved graphs. A curve denotes a variation in the rate (or speed) of a response over time.

Graphs representing reaction rates frequently have curves. A curve denotes a variation in the rate (or speed) of a response over time, while a straight line would represent a constant rate of reaction.

If a curve or straight line becomes horizontal, it means the reaction's rate has reached its maximum level and cannot vary any further.

Lines of best fit can also be used to spot outliers and anomalous data that won't fall along the line of greatest fit. Additionally, lines of best fit may be extrapolated (extended). This enables us to forecast values that are outside the range of the given data using a graph.

The equation of the line which passes through (-4, -6) and is parallel to the line y = -3x + 3 is y = -3x -18

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Finding the slope between two separate locations and calculating the slope of a line are related tasks. In general, we require the values of any two separate coordinates of a line in order to determine its slope.

Any two different points on a line may be used to compute the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

The slope of the given line

y = -3x + 3 is - 3 (from slope intercept form.

So the equation of the line is

y = -3x + c

where c is the y intercept.

The line passes through (-4, -6) so putting this values in the equation we get,

-6 = -3*(-4) + c

⇒ c = -6 - 12 = -18

The equation of the line which passes through (-4, -6) and is parallel to the line y = -3x + 3 is y = -3x -18

If Rich is going to a 4-year college. He was given a 10-year, unsubsidized student loan for $7,900 at 4.29%. His monthly payment is $87.31.

Monthly payment can be defined as the money a person received on a monthly basis.

Now let find the monthly payment

Using this formula to find the monthly payment'

M = P(r/12) (1+ r/12)^12t / (1+r/12)^12t -1

Where:

M = Monthly payment = ?

P = Principal

r = Rate

t = Time

Monthly payment = 7900 (0.0429/12) ( 1+ 0.0429/12)^12×10 ÷  ( 1+ 0.0429/12)^12×10 -1

Monthly payment = 7900 (0.003575) ( 1+ 0.003575)^120÷  ( 1+ 0.003575)^120 -1

Monthly payment =7900 (0.003575) ( 1.003575)^120 ÷  ( 1.003575)^120 -1

We can start by using the following formula to find the original price:

Original price = Sale price / (1 - (Discount percentage / 100))

To use this formula, we need to convert the discount percentage from 18% to a decimal. We can do that by dividing 18 by 100.

Discount percentage as decimal = 18 / 100 = 0.18

Now we can use this value in the formula:

Original price = $522.75 / (1 - 0.18) = $522.75 / 0.82 = $638.57

So the original price of the television set was $638.57.

Rounding to the nearest cent, the original price of the television set is $638.57

The probability of getting either 1 or 6 more than two times is P(T)=121/1296

To find the probability we use the binomial distribution.

Here we have 4 independent experiments. Each time, the sample space is (1,2,3,4,5,6) so the prob of getting a 6 is 1/6.

so p=1/6

prob of coming 6 and q= 1-p = 1-(1/6)=5/6

prob of not coming 6 is 5/6

p= prob of success. here our success event is getting 6

q= prob of failure. here our failure event is not getting 6

no of trials n=4

now using the binomial distribution formula:

ncr(p)^n(1-p)^r

here we want at least two 6, desirable outcomes are two 6 or three 6, or four 6 because at least two 6 doesn't mean that we can't get more than two 6 .

so r in these cases take the value of 2,3,4 respectively.

so for r=2

c(4,2)*(1/6)^2*(5/6)^2

P(A)=  150/1296

for r=3

c(4,3)*(1/6)^3*(5/6)^1

P(B)= 20/1296

for r = 4

c(4,4)*(1/6)^4*(5/6)^0

P(C)= 1/1296

here we will add these prob ..Getting two 6 fulfills our condition so we will stop and calculate the prob and keep it aside

now adding these we get P(T)=P(A)+P(B)+P(C).

(150/216) +(20/216) + (1/216)

P(T)= 171/1296

1(-8x - 4y = -20)

3x + 2y - 8x - 4y = 11 - 20 gives -5x - 2y = -9

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

3x + 2y = 11....(1)

-8x - 4y = -20....(2)

When solved initially the value of equation is -

3x + 2y - 8x - 4y = 11 - 20

-5x - 2y = -9

Multiply equation (1) by 2 -

2(3x + 2y) = 2 × 11

6x + 4y = 22.....(3)

Simplify the equation (2) and (3) by adding -

-8x - 4y + 6x + 4y = -20 + 22

-2x = 2

x = -1

Substituting the value of x = -1 in equation (1) -

3x + 2y = 11

3(-1) + 2y = 11

Simplifying the equation -

-3 + 2y = 11

2y = 11 + 3

2y = 14

y = 7

The required value of k will the system of linear equations has infinite number of solutions is 8.

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. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Given set of equations is

kx + 4y = k - 4 ...(i)

16x + ky = k ...(ii)

We apply Cramer's rule to find the value of k.

Here,

D = k² - (16 × 4)

= k² - 64

= (k + 8) (k - 8)

D1 = k (k - 4) - 4k

= k² - 4k - 4k

= k² - 8k

= k (k - 8)

D2 = k² - 16 (k - 4)

= k² - 16k + 64

= (k - 8)²

= (k - 8) (k - 8)

For infinite number of solutions, we must have

D = 0 = D1 = D2

⇒ k = 8,

since (k - 8) is the common factor in D, D1 and D2.

∴ the required value of k is 8.
