Answer:
You can substitute the x value of coordinate (x,y) in the equation. If the outcome = the y value in the coordinate (x,y), then you have determined it to be on the system of linear equations.
Step-by-step explanation:
Point P has a coordinates: ( Px , Py ).
You can choose which value is easy to substitute. Eighter start with the Py or you could start with the Px. It could save you time if you pick the right one for the job.
If you want to verify if any point is valid in any (linear) equation(s), you can:
a) substitute the x value of coordinate (x,y) in the equation, and if the outcome has the same value as y in the coordinate (x,y), then that point is a valid solution of the (linear) equation.
b) substitute the y value of coordinate (x,y) in the equation, and if the outcome has the same value as x in the coordinate (x,y), then that point is a valid solution of the (linear) equation.

Answer:
24 cups of flour
Step-by-step explanation:
For every 1 cup of flour, Jayla need 1/4 cups of water
1/4 in decimal form is 0.25
so
6÷0.25=24
Given:
A number between 80 and 100
That has exactly 4 factors one of which is 5.
I'll choose 90. It is between 80 and 10.
90 ÷ 5 = 18
18 ÷ 6 = 3
3 ÷ 1 = 3
Factors of 90 are: 1, 3, 5, and 6.
1 x 3 = 3
3 x 5 = 15
15 x 6 = 90
1 x 3 x 5 x 6 = 90
