Answer:

y=3 x=2/5

Step-by-step explanation:

5x + 3y =11

5x - 3y =-1

ok for the first one when 3y way positive the answer is positive and when it was negative the answer was negative meaning it is freater then 5x

the difference between the answer 11--1= 12 shows how much the difference between the negative and positive y  is so 12 has to equal 4y

4y=12

so y has to be 3

and if y is 3  we plug it back into the equations

5x+3(3)=11

5x+9=11

5x=2

A recipe requires 2.5 teaspoons of sugar to make a candy bar. Which equation shows the number of teaspoons of sugar, y, needed t
noname [10]

Answer:

2.5x-y=0

Step-by-step explanation:

You will have to understand this question before solving

According to the question 2.5 teaspoon of sugar is required for making one candy

Then y teaspoon of sugar is required to make y candy

Let's start

2.5 sugar=1 candy

y sugar=x candy

Let's cross multiply

y=2.5×x

y=2.5x

Which can also be written as

2.5x-y=0

Therefore the final answer is 2.5x-y=0

Take the equation: y = 520 + 14x and put each value from the table in for x and y.  

100 = 520 + 14 * -30
100 = 520 + -420
100 = 100   When we get an answer like this where the numbers on both sides of the equation match, we know that this (x,y) point is a part of the solution to the function.

So, you would work through each line in the table.  If they are all like the one above, the answer is Yes.  If not, it is no.
