If y varies directly as x, and y =15 as x= -3, find y for the x-value of 6.
VMariaS [17]

Answer:

the answer is -30.

Step-by-step explanation:

for each x-value, you will multiply it by -5 to get your y-value. i say this because if y-15 when x=-3, if you divide the x from y (so 15/-3) you get -5 which is the number in which y varies by. so you will take 6 and multiply it by -5 which gives you -30.

Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at
bekas [8.4K]

The number of people increased by 2.

This means as a ratio it is now 6/4 as many as originally planned.

6/4 can be reduced to 3/2.

The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.

This means the length of time the food lasts is reduced by 1/3, which is 33.3%

In​ 1990, the average income for an American worker was​ $1,518 per month. In​ 2000, the average income for an American worker w
mario62 [17]

Answer:

Decreased

Step-by-step explanation:

-The rate of growth in food prices can be calculated using the compound interest formula as:

A=P(1+i)^t\\\\1402=657(1+i)^{10}\\\\(1+i)=(\frac{1402}{657})^{0.1}\\\\1+i=1.07874\\\\i=0.07874

We use the calculated growth rate in food prices to find the potential future value of a 90's income:

A=P(1+i)^n\\\\=1518(1.07874)^{10}\\\\=3239.21

#Compare this calculated value to the stated value:

3239.21>2632

Hence, the real value of income has decreased since it's less than it's future value over the 10-year period.
