Tell me the y-intercept of the line: 2x - 3y = 9

butalik [34]

Answer:

y-intercept: (0,-3)

Step-by-step explanation:

Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:

$2(0)-3y=9\\0-3y=9\\-3y=9\\y=\frac{9}{-3} \\y=-3$

Therefore, the point is (0,-3).

You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one

sergey [27]

Step-by-step explanation:

1. making the equation:

shoes = x

shirts = y

175 = x + 3y

x = 4y

2. graph it (I'm using desmos)

the green line is for 175 = x + 3y and the purple one is for x = 4y

3. find the price

x = 4y

175 = 4y + 3y

175 = 7y

y = 175/7 = $25

price of the shirt = $25

x = 4y = 4*25 = $100

price of a pair of shoes = $100

Find the total cost for a $579 smartphone with 5% sales tax

tensa zangetsu [6.8K]

To find your answer first you must convert 5% into a decimal which will be 0.05. Then you will have to multiply 0.05 by 579 which will give you 28.95. The final step is to add $28. 95 which is the sales tax to $579 which will give you $550.05.
Final cost: $550.05
