Determine parallel, perpendicular, or neither!

1 answer:

6 0

Rearrange Line 1 and Line 3’s equations in the form of y = mx + c for easier comparison.

Lines 1 and 2 are parallel, because they have the same gradient.

Lines 1 and 3, and 2 and 3 are neither, because their gradients do not multiply to form -1.
(Gradients of perpendicular lines multiply to form -1.) c

Fantom [35]

Answer:

Katie saved $20.

Step-by-step explanation:

I assume that "served" is a typo for "saved". Also, I assume that Tata and Ted are the same person.

Let the amount Katie saved = k

Then, ted saved $6 less than 4 times k, or 4k - 6.

The total saved by both is k + 4k - 6.

The total saved by both is $94.

k + 4k - 6 = 94

5k - 6 = 94

5k = 100

k = 20

Answer: Katie saved $20.
