The length and width of the rectangular box are 13 ft and 6 ft respectively.
<h3>How to find the length and width of a rectangle?</h3>
The length of the batter's box on a softball field is 1 ft more than twice the width.
The area of the batter's box is 78 ft².
The length and width of the rectangular batter's box can be found as follows:
Therefore,
area of a rectangle = lw
where
Therefore,
area of the rectangular box = 78 ft²
l = 1 + 2w
Hence,
78 = (1 + 2w)w
78 = w + 2w²
2w² + w - 78 = 0
Hence,
w = 6 and w = -13 /2
we can only use positive values.
Therefore,
width = 6 ft
length = 2(6) + 1 = 13 ft

I think the answer is c I hope I am correct
Answer:
y = -9x-11
Step-by-step explanation:
The slope is -9 and a point is (-1,-2)
We can use point slope form
y-y1 = m(x-x1)
y--2 = -9(x--1)
y+2 = -9(x+1)
Distribute
y+2 = -9x-9
Subtract 2 from each side
y+2-2 = -9x-9-2
y = -9x-11
This is in slope intercept form (y=mx+b)
The linear functions are:
y = 6x - 2
x + y = 12
y = x
The non-linear functions are:
y = 3x³ + 5
y = x² - 33
Explanation:
Linear functions can be written in the form y = mx+b, where m is the slope and b is the y-intercept. In linear functions, the x variable has at highest an exponent of 1.
The first equation, y = 6x - 2, is in slope-intercept form; it is linear.
The second equation, y = 3x³ + 5, has an x with an exponent greater than 1; it is non-linear.
The third equation, y = x² - 33, has an x with an exponent greater than 1; it is non-linear.
The fourth equation, x + y = 12, can be written as y=mx+b:
x+y=12
Subtract x from both sides:
x+y-x=12-x
y = -x+12
This is a <span><u><em>linear </em></u></span>function.
The <u>fifth </u>equation, y = x, is in the form y=mx+b; in this case, m=1 and b=0. This is <u><em>linear</em></u>.
Answer:
Marry =10
Betty = 33
Step-by-step explanation:
Let's see what we need to do,
43 =
This will equal to 10 as we already know that Beth has $33.
