(a) Answer: One solution.

Explanation: two lines that have same slope with opposite sign will necessarily cross each other at a single point, as one is "pointing uphill" and the other "downhill."

(b) Answer: Infinitely many solutions.

Explanation:

2x + 3y = 5.5

4x + 6y = 11 | divide by 2

-->

2x + 3y = 5.5

--> equations are identical.

2x + 3y = 2x + 3y

so any (x,y) will satisfy this equation. This means infinitely many solutions.

Explanation:

Continuing the two lines it becomes obvious they will cross at one point (the solution)

(d) Answer: No solution

Explanation: If the two lines are parallel, they will never cross (by definition of "parallel"). Therefore there will be no solution to the corresponding linear system.

I don't know how to graph this

Musya8 [376]

It's simple bud. First you have to distribute the 4/9.
y-2=4/9(x-3)
y-2=4/9x-1.33 (then leave the y by itself)
y=4/9x-1.33+2
y=4/9x+0.67 done!

∣∣x+34∣∣=−11, How do you solve this

VMariaS [17]

Answer:

The answer is No Solutions

Step-by-step explanation:

Since this is absolute value, we know the answer has to be positive, because distance has to be positive. We see it is negative, and that cannot be, so the answer is no solutions.
