It's 4.4 because 5.7 minus 1.3 equals 4.4
4.4 is your answer
Answer:
1. It has two points in common with the x-axis.
2. The vertex in relation to the x-axis is at 
Step-by-step explanation:
The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.
To find them, substitute y=0 and solve for "x":

Use the Quadratic formula:

It has two points in common with the x-axis.
To find the vertex in relation to the x-axis, use the formula:

Substituting values, you get:

Answer:
8x^2 + 6xy - 5y^2 + 26
Step-by-step explanation:
See attached image.
Let's write 2 equations from the two statements given.
<em>Sarah spent 10 dollars on both oranges and apples</em>
<em />
Let the price of oranges be "x" and price of apples be "y", thus we can write:

Oranges cost 3 less than apples, thus we can say:

We can substitute this into the first equation and solve for y:

Thus, let's solve for x now,

We want the price of oranges (x), thus,
<em>Price of Oranges = $3.50</em>
Take the square root. The opposite of squaring something is taking the root :)
√x^2 = √26
x = √26
x = 5.099...
OR leave it if your teacher doesn't want a decimal since it can't be simplified anymore
