At the store, mimi paid 0.84 for seven oranges.

vagabundo [1.1K]

Since 7oranges=$0.84 find the unit rate by dividing 0.84 by 7 to get 0.12 then take that number and multiply it by 24 to get $2.88

In the system shown below, what are the coordinates of the solution that lies in quadrant IV?

katrin2010 [14]

Answer:

The coordinates of the solution that lies in quadrant IV are (2, -5)

Step-by-step explanation:

We have 2 equations, the first of an ellipse and the second of a circumference.

$2x^2+y^2=33\\x^2+y^2+2y=19$

To solve the system solve the second equation for x and then substitute in the first equation

$x^2+y^2+2y=19\\\\x^2 = 19 -y^2 -2y$

So Substituting in the first equation we have

$x^2 = 19 -y^2 -2y\\\\2(19 -y^2 -2y)+y^2=33\\\\38 -2y^2-4y +y^2 = 33\\\\-y^2-4y+5=0\\\\y^2 +4y-5 = 0$

Now we must factor the quadratic expression.

We look for two numbers that multiply as a result -5 and add them as result 4.

These numbers are -1 and 5.

Then the factors are

$y^2 +4y-5 = 0\\\\(y-1)(y+5) = 0$

Therefore the system solutions are:

$y = 1$ ; $y = -5$

In the 4th quadrant the values of x are positive and the values of y are negative.

So we take the negative value of y and substitute it into the system equation to find x

$y=-5\\\\2x^2+(-5)^2=33\\\\2x^2 = 33-25\\\\2x^2 = 8\\\\x^2 = 4$

$x = 2$ , and $x= -2$

In the 4th quadrant the values of x are positive

So we take the positive value of x

Which represents where f(x) = g(x)?

Anna [14]

The equation represents the intersections. The correct option is A:

f(2) = g(2) = 0
f(0) = g(0) = 4.

<h3>Which represents where f(x) = g(x)?</h3>

If we have two functions:

y = f(x) and y = g(x), the equation:

f(x) = g(x) gives the value of x such that the two functions have the same output. So, that equation gives the intersection points between the two graphs.

By looking at the graph, we can see that we have two intersections, one at:

(2, 0) and other at (0, 4).

This means that:

f(2) = g(2) = 0
f(0) = g(0) = 4.

So the correct option is the first one.
