Answer:

(7x-1)(x-3)

Step-by-step explanation:

7x^2 - 22x + 3

The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.

(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3

Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.

What percent of students ran the mile in 12 minutes or less?

otez555 [7]

41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran. Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.

Write the standard form of a line that passes through the given points (4,7) and (0,7)

VARVARA [1.3K]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

We have the points (4, 7) and (0, 7) → b = 7.

Calculate the slope:

$m=\dfrac{7-7}{0-4}=\dfrac{0}{-4}=0$

Therefore we have $y=0x+7=7$

The standard form: $Ax+By=C$

<h3>Answer: y = 7.</h3><h3><em>It's a horizontal line.</em></h3>
