Answer:

See below

Step-by-step explanation:

Line passes through the origin and has same x and y coordinate pairs,

y = x

<u>Points:</u>

(0, 3), (6, 1)

<u>The slope is:</u>

m = (1 - 3)/6 = -2/6 = -1/3

y = -1/3x + 3

<u>Points:</u>

(-1, 5), (0,1)

<u>The slope:</u>

m = (1 - 5)/(0 + 1) = - 4

y = -4x + 1

Please help me solve this

madam [21]

Answer:

x = 15

Step-by-step explanation:

we know that the total degree inside of a triangle made up of 180°

6x + 4x + 2x = 180

12x = 180

x = 15

To find each angle we multiple 4x , 6x, 2x by 15

4(15) = 60°

6(15) = 90°

2(15) = 30°

After 6 months, the total cost of Tanya’s gym membership was $200. After 8 months, the total cost was $260. Is this a proportion

ycow [4]

Answer:

Non-proportional; the rate of change is $30/month

Step-by-step explanation:

After 6 months, the total cost was $200.

After 8 months, the total cost was $260.

Find the rate of change using formula

$\dfrac{f(b)-f(a)}{b-a}$

Hence,

$\text{Rate of change}\\ \\=\dfrac{\$260-\$200}{8-6}\\ \\=\dfrac{\$60}{2}\\ \\=\$30\ \text{per month}$

At this rate, after 6 months Tanya paid

$\$30\cdot 6=\$180$

But after 6 months, the total cost of Tanya’s gym membership was $200.

It means the relationship passes through the point (0,20), not through the origin. Each proportional realtionship passes through the origin. Thus, this is not proportional relationship.
