Answer: one number is 104, the first number is 26 and the third number is 126

How to:

Let’s say the “first number” is Y, the “second number” is X, and the “third number” is Z. This makes Y=4x and Z=x+100. Then put it into an equation to find the sum: X+4x+x+100=256. Take away 100 from both sides of the equation and combine the like terms (the X’s). That leaves 6x=156. Then divide both sides by 6 to get x alone which is x=26. That is the first number. To find Y just multiply X by 4 and that’s Y=104. And lastly add 100 to x which is Z=126.

You have $30 dollars saved up. Every week you spend $6 at the arcade. Write an equation in slope intercept form that shows how m
Colt1911 [192]

Answer:

y = -6x + 30

Step-by-step explanation:

The inicial value you have is $30, so this will be the value of y after 0 weeks, that is, x = 0

After one week, you spend $6, so you will have y = 30 - 6 = 24 when x = 1.

With these pair of values, we can find the linear equation:

y = ax + b

for x = 0, y = 30:

30 = a*0 + b

b = 30

for x = 1, y = 24:

24 = a*1 + 30

a = 24 - 30 = -6

So, our equation is:

y = -6x + 30

Which equation defines the graph of y=x^2 after it is shifted vertically 3 units down and horizontally 5 units left? A) y=(x-5)^
jeka94
The answers is B because you set x+5=0 and x=-5 so that means that the graph needs to be shifted 5 units to the left because 5 is negative and to move 3 units down you just put a -3 at the end of the equation like this y=(x+5)-3
