First, multiply the numbers in the <span>parentheses, which is </span>3 times 7 is 21.
Then divide 40 by 1. 40/1 = 40
40 plus 3 is 43, 43 minus 21 is 22.
PLus 7 minus 5 is 24.

First things first. Think of the word
PEMDAS meaning parenthesis, exponents, multiplication, division, addition, subtraction.
First you would check for parenthesis which you do (3x7) so multiply both which come out to 21.
We can skip exponents and multiplication since we have already done it or may not have it. Next is division. Multiply 40 divide by 1 which is 40 now add 3 so 43. And lastly subtract 7-5=2
Your new equation is 43-21+2. So your answer comes out to 24! Hoped this helped.

What form of a linear equation is y - 6 = -4(x + 2) ?
Softa [21]

Answer:

Point slope form

Step-by-step explanation:

Given

y - 6 = -4(x + 2)

Required

Determine the form of linear equation

A linear has just three forms:

1. The slope intercept form.: This is always in form of y = mx + b

2. The point slope form: This is always in form of y - y_1 = m(x - cx_1(

2. The standard form: This is always in form of Ax + Bxx = c

<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>

Line n is perpendicular because it has the opposite reciprocal. 
Line p is neither because it does not have the opposite reciprocal nor same slope.
Line q is parallel because it has the same slope.
