Find the value of x when y = 3, (y + 5) + 3y = x.

x = 17

Step-by-step explanation:

Given

(y + 5) + 3y = x ← substitute y = 3

(3 + 5) + 3(3) = x, that is

8 + 9 = x, thus

x = 17

x=17

Step-by-step explanation:

This question is just like substitution,that is a number will be given to substitute a letter...

Ok let's start with the question

(y+5)+3y=x

And we are to determine the value of x when y is 3...

That means we will replace any where we see y with 3

(3+5)+3(3)=x

8+9=x

x=17

Therefore when y is 3,x is 17

Our final answer is 17

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
