Answer:

Slope:

7/3

y-intercept:

(0, −3)

Step-by-step explanation:

The slope of the line that passes through (2, 2) and (10, 6) is; 1/2.

The slope of parallel lines is the same. Slopes of perpendicular lines are negative reciprocals of each other. The slope of a line or straight object is the ratio of how much amount of rising occurs in correspondence to the increment in the run.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

We have been given that the line that passes through (2, 2) and (10, 6).

Let ( p,q) and (x,y) are (2, 2) and (10, 6) respectively.

Slope = [tex]m = \dfrac{y-q}{x-p}[/tex]

m = (2-6)/(2-10)

m = 4/8

m = 1/2

Then the slope is 1/2.

The linear equations are x  +  y  =  10 and (11.90)x  +  (13.10)y  =  (12.86)(10) and the value of x and y are 2 and 8 respectively.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A coffee distributor needs to mix a(n) Queen City coffee blend that normally sells for $11.90 per pound.

Let x and y be the quantity of Queen City coffee (lbs) and the quantity of Arabian Mocha coffee (lbs)

From the data given;

The equations can be framed:

x  +  y  =  10

(11.90)x  +  (13.10)y  =  (12.86)(10)

After solving the substitution method:

x = 2

y = 8

Thus, the linear equations are x  +  y  =  10 and (11.90)x  +  (13.10)y  =  (12.86)(10) and the value of x and y are 2 and 8 respectively.

A V-shaped graph belongs to an absolute value function or a piecewise function, never to a linear function (these are graphed only with a single line).

This is really trivial question.

So the answer is really trivial, as you can see.

But let's explain it a little bit more.

The only functions that have V-shaped graphs are piecewise functions (formed of two linear equations) or absolute value equations, neither of these are exactly linear (but they are made of "linear like parts").

Answer:

d

Step-by-step explanation:

The number of years must be non-negative.

This eliminates all of the options except for d.

A direct proportional relation can always be express as an equation of the form:

where k is the constant of proportionality. (This means that y has to be the result of multiplying a number by x)

Now, let's see at the option we have.

a)

Solving the equation for y we have:

Since we can write the equation in the form as a direct proportional relationship we conclude that option a shows a directly proportional relationship and that the constant is -1.

b)

For this case we have the equation:

From it we already can see that this means that x is directly proportional to y and that the constatn of porportionality is 0.125.

Now if we want we can solve the equation for y, then we have:

this equation shows that y is directly proportional to x and that the constant of proportionality is 8.

Notice that the the constant of proportionality changes if we write the relation as x directly proportional to y or if we write it as y directly proportional to x. Either way the relation express the same and it is directly proportional.

c) and d)

For this equations that we have a division in which one of the variables is the divisor (or the denominator); this means that the equation show a relation between x and y but their are not directly proportional. In fact this means that the equations show an inversely proportional relations.

Spanish club has 48 tickets which must be sold to reach the fund-raising goal as profit of $600.

What is profit?

In mathematics, the term profit can be explained as the amount which is on the standard cost price. For the profit, the amount of the commodity can be designed by the shopkeeper which is bigger amount as per the cost price.

According to the question, the total profit from the Spanish club fundraiser varies directly with the number of dinner tickets sold.

If the sale of 14 tickets results in a profit of : $175.

Therefore, Profit in 1 ticket = 175/14 = 12.5 dollars

Let us assume 'x' tickets are sold in order to reach the fund-raising goal of $600.

x = (14/175)(600) = 48

x = 48 tickets

Hence, 48 tickets must be sold to reach the fund-raising goal as profit of $600.

Before we can proceed in graphing the complex number, let's get the sum of the two given complex numbers first.

When adding complex numbers, simply combine similar terms like real-to-real and complex-to-complex only.

So, we have:

Hence, the sum of the two complex numbers is 1 - 4i.

When plotting a complex number in the plane, the real number acts as the x-coordinate and the complex number acts as the y-coordinate.

Hence, the x-coordinate is 1 while the y-coordinate is -4.

The equation of tangent is y = -2x + 20. The slope of the tangent line is negative 2. And coordinate of point A is (10, 0). And the length of AB is 22.36 units.

The equation of the circle with center at origin and radius r is given as,

x² + y² = r²

The slope of the tangent line to the circle at points (8, 4) is given as,

2x + 2y (dy/dx) = 0

dy / dx = - 8 / 4

m = - 2

Then the equation of the line is given as,

y = -2x + c

The equation is passing through (8, 4), then we have

4 = -2(8) + c

c = 4 + 16

c = 20

The equation is y = -2x + 20. Then the x-intercept is given as,

y = 0

-2x + 20 = 0

2x = 20

x = 10

Then the length of the line is given as,

AB² = (10 - 0)² + (0 - 20)²

AB² = 100 + 400

AB = √(500)

AB = 22.36 units

The given sequence is

1, 1/2, 1/4, 1/8......

we can see that the ratio of the consecutive terms is the same. We have

1/2/1 = (1/4)/(1/2) = (1/8)/(1/4) = 1/2

This means that it is a geometric sequence

To find the amount of the substance left after 21 half lifes, we would find the 21st term of the sequence. The formula for finding the nth term of a geometric sequence is

an = a1r^(n - 1)

a1 = 1

n = 21

r = 0.5

Thus,

a21 = 1 * 0.5^(21 - 1) = 0.5^20

a21 = 0.00000095367

a21 = 1/1048576

The answer makes sense in the problem context because it follows the common ratio that was established at the begining.

The equation for exponential growth has the following form:

Where a is the initial amount, r is the growth rate and x is the variable.

In this case, we know the amount after the first year and the growth rate and the variable is the number of years. So, replacing a by 8,000 and r by 0.67 and x by (n-1) because we will not include the 1st year, we get:

The dividend when the divisor is 8 and the quotient is 96 with a remainder of 3 is 771.

The dividend in mathematics is the value that is divided by another value to obtain the result. The dividend is the starting point for any division method. The dividend is one of four critical components of the division process. It is the whole that is to be divided into equal parts.

A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another integer to produce n. In this case, n is also said to be a multiple of m.
