Answer:

2/9

Step-by-step explanation:

First, you want to make the 1 and 1/8 an improper fraction. now it should look like 1/4 divided by 9/8. There's this method I learned called "Keep, Change, Flip". Basically, you want to keep the 1/4 the way it is, change the division symbol to a multiplication symbol, and flip the 9/8 so it is now 8/9. The equation now looks like 1/4 x 8/9. The answer should be 8/36, which also equals 2/9. If you have any questions, I'll try my best to answer them. Sorry if this is too long.

Consider the system:

Gnom [1K]

Answer:

Step-by-step explanation:

In this problem, we have the following linear equations:

y=3x+5

y=ax+b

We know that a linear equation is an equation for a line. In a system of linear equations, two or more equations work together.

1. What values for a and b make the system inconsistent?

A system is inconsistent if and only if the lines are parallel in which case the system has no solution. This is illustrated in the first Figure bellow. Two lines are parallel if they share the same slope. So, the system is inconsistent for:

a=3

for any value of b

2. What values for a and b make the system consistent and dependent?

A system is consistent if and only if the lines are the same in which case the system has infinitely many solutions. This is illustrated in the second Figure bellow. So, the system is consistent and dependent for:

a=3 and b=5
