Step-by-step explanation:

An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. Find the values of x and y in the following triangle. y + 92° = 180° (interior angle + adjacent exterior angle = 180°.)

If y varies consistently with x then it would copy what happens, in a manner of speaking.

In this case, y increases by three, x would either add 3 or subtract 3

Answer:

[tex]P= 0.4x+ 0.4y[/tex]

Step-by-step explanation:

Given data

Profit from apple= $0.4

Profit from banana= $0.4

Let the number of Apples sold be x, and the number of bananas sold be y

and the total profit be P

Hence the expression for the total profit is given as

[tex]P= 0.4x+ 0.4y[/tex]

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line is y = -0.5x + 5

Option C is the correct option.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line y = mx + c.

The line passes through (4, 3) and (6, 2).

This means,

We can find the slope using the coordinates (4, 3) and (6, 2).

Slope = m

m = (2 - 3) / (6 - 4)

m = -1 / 2

Now,

For the y-intercept.

Take any point.

(4, 3) = (x, y)

y = mx + c

3 = (-1/2)4 + c

3 = -2 + c

3 + 2 = c

c = 5

Now,

m = (-1/2) = -0.5

c = 5

The equation of the line is y = -0.5x + 5

Thus,

The equation of the line is y = -0.5x + 5

Option C is the correct option.

Answer:

D

Step-by-step explanation:

The sum to n terms of an arithmetic series is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = 12, d = 4 and n = 30 , then

[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × 12) + (29 × 4) ]

     = 15(24 + 116)

     = 15 × 140

     = 2100 → D

The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100, therefore the correct answer is D.

The sum of n terms of an arithmetic series can be easily found using a simple formula which says that, if we have an arithmetic series whose first term is a and the common difference is d, then the formula of the sum of n terms of the arithmetic series is as follows

Sn = n/2 [2a₁ + (n-1)d].

as given in the problem

a₁ =12, d = 4, and n = 30

Sn = 30/2 [2×12 + (30-1)×4]

    = 2100

The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100.
