<span> The quadratic formula says that any quadratic equation of the form ax^2 + bx + c, then
x=(-b ± √(b^2 - 4ac))/2a, and so because of the square root, theres
obviously going to be no x-intercepts if b^2 - 4ac is negative, one
x-intercept if its zero, or two if its positive. So to calculate the
discriminant, which is whether it has an intercept, no intercepts or two
intercepts is:
∆=b^2 - 4ac, where delta, the greek equivalent of D, is used to represent the discriminant.
In the above equation a=-4, b=3 and c=-2, so
∆=3^2 - 4*-4*-2=9 - 32=-23, so because the discriminant is negative, then there are no x-intercepts.

This makes no sense because the rows have to be smaller than the bookshelf
the rows fit in the bookshelf
the way to do it would be height of bookshelf/height per row=number of rows (round down)
if we used that, then 112/316=0.35 rows
round down
0
so we got 0 shelves because it is impossible to have a row higher than the bookshelf that it is on
Answer:
(c) 22
Step-by-step explanation:
The range of a set of data is found from a box and whisker plot by subtracting the lower whisker value from the upper whisker value:
range = 66 -44 = 22
The range in the number of pretzels is 22.
The slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.
<h3>What is the slope?</h3>
A numerical assessment of a line's angle relative to the ground is known as the slope.
The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.
The slope of the line is found as;
The standard line equation is;
y-y₁=m(x-x₁)
Hence, the slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.

(100-9^2)/3
PEMDAS: parenthesis, exponents, multiply, divide, add, subtract
Lets' work on the parethesis first.
100-9^2
We can do the exponent first, 9^2=81, so 100-81=19
Then we divide and 19/3 is your final answer.
