Answer:
Step-by-step explanation:
we know that
1 mile=5,280 feet
we have that
Elena ran 2-1/2 miles
<em>Convert mixed number to an improper fraction</em>
Convert miles to feet
Answer:
Option D. No solution
Step-by-step explanation:
<u>We have the equation of a line:
</u>
We find their cut points.
<em>Cut point with the y axis. (x = 0)
</em>
<em>Cut point with the x axis. (y = 0)
</em>
.
The line cuts to the x-axis at and cuts the y-axis at
<u>We have a parabola
</u>
We can factor this quadratic equation by looking for 2 numbers that when multiplied give as result -3 and that when adding these numbers as a result -2. These numbers are -3 and 1.
Then the factors are:
The zeros are 3 and -1. So <em>the parabola cuts to the x axis at points </em><em>3</em><em> and</em><em> -1</em><em>.
</em>
<em>Now we find the cut points with the y axis. (x = 0)
</em>
<em>The parabola cuts to the axis y in y = -3.
</em>
Now we can graph the line and the parabola. Observe the attached image.
<em>The system has no solution because the line and the parabola never intersect or touch each other. The answer is the option D</em>
I would say 169 but I’m not positive
Answer:
Not a function
Step-by-step explanation:
This is not a function because there are different outputs for the same input.
Answer:
Step-by-step explanation:
Using the same proportion as the previous question
11/x = x / 8 Cross multiply
x^2 = 88 Factor 88 into at least 1 perfect square and something
x^2 = 4 * 22 Take the square root of both sides
x = sqrt(4 * 22)
x = 2*sqrt(22)
