We need to solve this by PEMDAS. P=parenthesis, E=exponents, M=multiplication, D=Division, A=Additions, S=Subtraction. First we solve this problem by solving the inside of the parenthesis, 5*3, which is 15. The next step is E, exponents, we use 15 to the second power to get 225, and then we add 3 to the 225, and the total of this problem is 228.

What is the equation of the line that passes through the point (-4,8) and has a slope of -1/4
iragen [17]

Answer:

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here, $ m = \frac{-1}{4} $ and $ (x_1,y_1) = (-4,8) $

Substituting in the equation:

$ y - 8 = \frac{-1}{4} (x + 4) $

$ \implies 4y - 32 = -x - 4 $

$ \implies x + 4y - 28 = 0 $

If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the i
otez555 [7]

Answer:

First Integer = n = 45

Second Integer = n+1 = 45 + 1 = 46

And Third Integer = n+ 2 = 45 +2 = 47

Step-by-step explanation:

Let First integer = n

Second Integer = n+1

Third Integer = n+2

According to the question given (If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third) the equation will be:

138 - n = (n+1) + (n+2)

Solving the equation:

138 - n = n+1+n+2

138 - n = 2n+3

138 - 3 =2n +n

135 = 3n

135/3 = n

=> n= 45

So, First Integer = n = 45

Second Integer = n+1 = 45 + 1 = 46

And Third Integer = n+ 2 = 45 +2 = 47

Solve this problem using substitution
Sergeeva-Olga [200]
Solving for (x,y)
(x-y=8)
(x=y-8) & (y=x-8)

solving for (y,x)
(2y=2x-16)
(y=x-8)&(x=y+8)
