Answer:

The only point (0,0) lies inside the shaded region and hence it gives a solution for the set of inequalities.

Step-by-step explanation:

See the graph attached to this question.

The solution of the set of inequalities is given by the shaded region on the graph.

Now, the point (0,5) is outside this shaded region, hence it can not be the solution.

The point (3,0) also is outside this shaded region, hence it can not be the solution.

The point (-3,0) also is outside this shaded region, hence it can not be the solution.

Now, the only point (0,0) lies inside the shaded region and hence it gives a solution for the set of inequalities. (Answer)

Juan bought fruit from the grocery store. The variables below define his purchase. Juan’s bananas cost half as much as apples. W

mixas84 [53]

Answer:

$B = \frac{1}{2}A$

$A = 2B$

Step-by-step explanation:

Given

Represent apple with A and Banana with B

Required

Determine the relationship between A and B

From the question, we understand that:

B costs half as much as A

This can be represented as:

$B = \frac{1}{2} * A$

$B = \frac{1}{2}A$

Multiply both sides by 2

$2*B = \frac{1}{2}A*2$

$2B = A$

$A = 2B$

What is the percent of change from 74 to 112? rounded to the nearest percent

ruslelena [56]

Answer:

The percent of change from 74 to 112 is 51%.

Step-by-step explanation:

Given:

The percent of change from 74 to 112.

Now, the difference between the numbers $112-74=38$ .

Then, calculating the percentage of the result by $74$ .

$\frac{38}{74}\times100$

$=0.5135\times100$

$=51.35%$ .

Round to the nearest percent of $51.35%$ is $51%$ .

Therefore, the percent of change from 74 to 112 is 51%.

If f(x) = 3x + 4 and g(x) = 5 − x, what is the value of (f · g)(x)?

alex41 [277]

F(x)·g(x) = (3x +4)·(5 -x) = -3x^2 +11x +20

(f·g)(x) = -3x^2 +11x +20

sergeinik [125]

Given that Trent's watch runs at half the speed it should run, this implies that

for every hour passed, his watch moves by half an hour.

Hence, for every half-hour passed, Trent's watch moves by 15 minutes.

Hence, when the real time is 10:30 am, Trent's watch will show 9:15 am.
