Hi ;-)

$\text{s}=-8 \ \text{and} \ \text{t}=\frac{3}{4}\\\\\text{s}^2\text{t}-10=(-8)^2\cdot\frac{3}{4}-10=\\\\=64\cdot\frac{3}{4}-10=16\cdot3-10=48-10=\boxed{38}$

How many points of intersection does this system have? y = 3 x minus 4. Negative 3 x y = 4. Zero points of intersection one poin

defon

A point of intersection is a point where two lines or curves meet.

There are zero points of intersection.

Given

The equations are;

$\rm y = 3x-4\\\\-3x+y=4$

<h3>What is the point of intersection?</h3>

A point of intersection is a point where two lines or curves meet.

There are two methods to find a point of intersection graphically by graphing the curves on the same graph and identifying their points and another one is to solve the equation and find the value of x and y.

Adding both the equation

$\rm y-3x-3x+y=-4+4\\\\2y=6x\\\\y=3x$

Substitute the value of y in the equation

$\rm y=3x-4\\\\3x=3x-4\\\\3x-3x=-4\\\\0=-4$

Hence, there are zero points of intersection.

A baseball collector took inventory of all of his baseball cards along with the value of each card. The box plot represents the

love history [14]

Answer: less than 25%

Step-by-step explanation:

The box plot can be read as follows:

The first black dot is the minimum value.

The first half of the rectangle is the lower quartile.

The line that separates the two rectangles is the median.

The second half of the rectangle is the upper quartile

The final point is the maximum.

Knowing that each quartile represents about the 25% of the elements for the set, we can see that both lower and upper quartile (and the 25% of the elements that come after the upper quartile) cost more than $45.

Then we know that at least the (25% + 25% + 25%) = 75% of the cards in the collection cost more than $45.

And we also have elements that are not in the lower quartile that cost more than $45, but we can not determine the percentage that they represent.

So we can only conclude that more than the 75% of the collection costs more than $45.

Now we want to know the percentage of the baseball cards valued at less than $45.

So if more than 75% is valued at more than $45.

Then less than 25% is valued at less than $25.

Does the graph represent a function?

stiv31 [10]

No it does not. Any function that has any of the same X vaules (The line going up left to right) is not a function.
