Answer:
Equation of line b in standard form is:
Option A is correct.
Step-by-step explanation:
We need to find equation of line b that passes through the point ( (6,4) and has a slope of -2.
First we need to find y-intercept of line using formula: where m is slope and b is y-intercept.
Using m=-2 , x=6 and y=4 the y-intercept will be:
Now finding the equation of line having slope m=-2 and y-intercept b=-11
Writing the equation in standard form
So, equation of line b in standard form is:
Option A is correct.
Answer:
120x^3y^7
We can use the Pascal's triangle to solve this question.
This pascal's triangle is shown in the Image below. To build the triangle, begin with the number 1 at the top, then continue placing numbers below it in a triangular pattern. In this way, each number are the numbers directly above added together. So, the expression is :
(x+y)10
After you do the steps you be left with:
120x^3y^7
3.08937142 x 10^1

Answer:
1. 2/5s + 8
2. -24
Step-by-step explanation:
1.
2/5(s + 20)
(2/5)(s) + (2/5)(20)
2/5s + 8
2.
-6(12 - 8)
(-6)(12) - (-6)(-8)
-72 + 48
-24
