The y-intercept is 4.

If you have x-4y=-16, in slope intercept form it is y=1/4x+4.

Write the equation of the line that passes through the given point and has the given slope:

Wewaii [24]

Answer:

$\displaystyle 4x - y = 21, -4x + y = -21, or\:y = 4x - 21$

Step-by-step explanation:

In this case, the y-intercept and rate of change [slope] are given to us, so just put it in Slope-Intercept Form:

$\displaystyle y = 4x - 21$

If you want it in Standard Form:

y = 4x - 21

- 4x - 4x

_________

$\displaystyle -4x + y = -21\:OR\:4x - y = 21$

One gram of a certain health food contains 7 percent of the minimum daily requirement of vitamin E and 3 percent of the minimum

Liula [17]

Answer:

Approximately 34 grams of the healthy food

Step-by-step explanation:

For know the minimum value to be eaten daily to provide the requirement of both vitamins, is necessary to calculate the minimum value for every vitamin, so:

vitamin E: We are going to use the rule of three in which 1 gram have 7% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:

1 gram --------------7%

X grams -----------100%

$X=\frac{1 gram* 100}{ 7 } = 14.285 grams$

So, it is necessary approximately 15 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.

vitamin A: We are going to use the rule of three in which 1 gram have 3% of the minimum daily requirement, then how many grams are going to be be the 100% of the daily requirement:

1 gram --------------3%

X grams -----------100%

$X=\frac{1 gram* 100}{ 3 } = 33.33 grams$

So, it is necessary approximately 34 grams of healthy food to complete th 100% of the minimum daily requirement of vitamin E.

Finally for satisfy with both minimum daily requirement, we need to eat at least 34 grams of healthy food, because it is the maximum between the two X values.
