Kazeer [188]

Answer:

$y = -\frac{2}{5}x -\frac{1}{5}$

Step-by-step explanation:

Given

Passes through: $(2,-1)$

Parallel to: $2x + 5y = 15$

Required

First, calculate the slope of the parallel line

$2x + 5y = 15$

Make y the subject

$5y = 15 - 2x$

Divide through by 5

$y = 3 - \frac{2}{5}x$

$y =- \frac{2}{5}x+3$

An equation in slope intercept has the form:

$y = mx + b$

Where:

m = slope

$y = mx + b$

So:

$m = -\frac{2}{5}$

The required is parallel to $2x + 5y = 15$ .

This mean, the same slope

The equation is the calculated using:

$y - y_1 = m(x - x_2)$

This gives:

$y - (-1) = -\frac{2}{5}(x - 2)$

$y +1 = -\frac{2}{5}x +\frac{2}{5}*2$

$y +1 = -\frac{2}{5}x +\frac{4}{5}$

$y = -\frac{2}{5}x +\frac{4}{5}-1$

Take LCM

$y = -\frac{2}{5}x +\frac{4-5}{5}$

$y = -\frac{2}{5}x -\frac{1}{5}$

i.e.

$y = -2/3x -1/5$

$a+b+c=180, \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\$

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.

Complete the statement to describe the expression (a+b+c)(d+e+f)

kherson [118]

Answer:

The given expression consists of 2 factors, and each factor contains 3 terms.

Step-by-step explanation:

Given the expression (a+b+c)(d+e+f)

Factors are parts of expression that are connected by multiplication. we are multiplying (a+b+c) and (d+e+f) so we said (a+b+c) and (d+e+f) are factors of the expression.

Hence, there are 2 factors in given expression.

A mathematical expression contains numbers, variables and operators joined by addition, subtraction, multiplication, and division. The parts of the expression that are connected with addition and subtraction are known as terms.

In each factor (a+b+c) and (d+e+f) three terms are connected by addition. Hence, there are 3 terms in both the factors.
