Answer:

y=7+3x

Step-by-step explanation:

Since she already has 7 in her account and she ADDS 3 more each day you would multiply 3 by x which represents the number of days and add that to seven because she already had it. This would equal to Y which represents the total in her account

An endpoint of a line segment is (4,5) and the midpoint of the line segment is (3, -2). Find the other endpoint.
Dimas [21]

Answer:

(-8,1)

Step-by-step explanation:

Using the equation for midpoints we can find:

\frac{(5+y)}{2} =3,  \frac{(4+x)}{2} =-2

y+5=6,      4+x=-4

y=1, x=-8

sry it's backwards

(-8,1)

Hope this helps!

PLZ HELP ME, THIS IS URGENT! I’m completely lost... :(
Leno4ka [110]
Let’s solve this step by step. :)

First, let’s assign variables for the missing number: x and y.

so the 3 numbers would be x, y and 28

then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81

Using the first equation, we can get x = 61-28 = 33

Using the 2nd equation, we can get y = 76-28 = 48

then, we can verify if our answer is right by substituting these values in the 3rd equation:

x + y = 81
33 + 48 = 81
81 = 81 ✔️

So the 3 numbers are 28, 33 and 48.
