In the given information, (0,5), x is 0 and y is 5. What we need is the information on x.
x is 0.
x = 0 is the equation of the line.
Answer:
x=0.
Step-by-step explanation:

The length of a parking lot is 4 yards more than the width. If the area of the parking lot is 117 square yards, find the dimensions of the parking lot.
A parking lot's length is 4 yards longer than its width. The dimensions of the parking lot are width=9 and length =12.
Given that,
A parking lot's length is 4 yards longer than its width.
We have to determine the parking lot's measurements if the area is 117 square yards.
Let us take the width as x and we get the length as x+4.
We can write as,
x(x+4)=117
x²+4x=117
x²+4x-117=0
x²+13x-9x-117=0
x(x+13)-9(x+13)=0
(x+13)(x-9)=0
x+13=0 and x-9=0
x=-13 and x=9
Therefore, The dimensions of the parking lot are width=9 and length=12.

How far can a woman drive into the tiwnif she drives out at 40 miles per hour,return over the same rod at 30 miles per hour, and spends 8 hours away from home, including a 1 hour stop for luch
Given the time, the distance that the.womn drives will be 240 miles.
How to calculate the distance?From the information illustrated, the woman drives out at 40 miles per hour, return over the same road at 30 miles per hour, and spends 8 hours away from home.
It should be noted that the average speed will be illustrated as:
= (2 × r1 × r2) / +r1 + r2)
= (2 × 40 × 30) / (40 + 30)

Answer:
3x-2y=10

Step-by-step explanation:
Slope-intercept form:

where:
m = slopeb = y-intercept-----------------------------------------------------------------------------------
Given inequality:
[tex]3x-2y < 10[/tex]
Rearrange the given inequality to make y the subject:
[tex]\implies 3x-2y+2y < 10+2y[/tex]
[tex]\implies 3x < 10+2y[/tex]
[tex]\implies 3x-10 < 10+2y-10[/tex]
[tex]\implies 3x-10 < 2y[/tex]
[tex]\implies 2y > 3x-10[/tex]
[tex]\implies \dfrac{2y}{2} > \dfrac{3}{2}x-\dfrac{10}{2}[/tex]
[tex]\implies y > \dfrac{3}{2}x-5[/tex]
Compare this with the slope-intercept form.
Therefore:
slope = ³/₂y-intercept = (0, -5)When graphing inequalities:
< or > : dashed line.≤ or ≥ : solid line.< or ≤ : shade under the line.> or ≥ : shade above the line.To graph the given inequality using its slope and y-intercept:

What is the probability of flipping a coin 7 times and getting heads 4 times?Round your answer to the nearest tenth of a percent.A. 27.3%B. 0.8%C. 5.5%D. 16.4%
We know that
• The probability of a head is 1/2.
,• The probability of a tail is 1/2.
Notice that the number of times they flip a coin is 7. Since both probabilities are the same, we just have to multiply 1/2 seven times by itself.
[tex]P=(\frac{1}{2})^7[/tex]Now, we multiply the probability with 7 since there are 7 possibilities.
[tex]P=7\cdot(\frac{1}{2})^7=7(0.0078125)=0.0546\approx0.055[/tex]Then, we multiply by 100 to express it as a percentage.
[tex]0.055\cdot100=5.5[/tex]Therefore, the answer is C. 5.5%.8. There were a total of 117 football games in

What is division?Compared to multiplication, division is the opposite. If three groups of four add up to 12, then division of 12 into three groups of equal size yields four in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division. It is referred to as a method of division to divide anything. According to the degree of difficulty, there are three different sorts of division procedures. These include the bus stop approach, the chunking method, and the long division method. The chunking method is also known as division by repeated subtraction.
Given Data
A total of 117 football games in the season, and 33 were played at night.
The season was nine months long.
Each month same numbers of game were played.
So,
117 ÷ 9

The right angled triangle has an area of 22.5 cm² X+1 X-3 help quick with no calcalator way or quadratic formula
Answer:
x = 8
Step-by-step explanation:
You want the value of x for a right triangle with side lengths (x+1) and (x-3) and an area of 22.5 cm².
Triangle areaThe area of a triangle is given by the formula ...
A = 1/2bh
Then the area of this triangle is ...
22.5 = 1/2(x -3)(x +1)
45 = x² -2x -3
48 = x(x -2) . . . . . . . add 3 and factor out x
We know that 48 can be factored as (8)(6). Comparing this to x(x-2), we see that x=8.

Additional comment
x could also be -6, but that would make the side lengths be negative. The only applicable solution for this geometry is x=8.
Which of the ten basic functions in

Step-by-step explanation:
You want to know which list of functions has the same graph when reflected across both the y- and x-axes.
Odd functionReflection across the y-axis transforms the function to ...
f(x) ⇒ f(-x)
Reflection across the x-axis transforms the function to ...
f(x) ⇒ -f(x)
Hence, reflection across both axes transforms the function to ...
f(x) ⇒ -f(-x)
A function that has the characteristic that f(x) = -f(-x) is an odd function. Its graph is symmetrical about the origin. We can check to see if the functions of interest match this definition of an odd function:
x³ = -(-x)³ . . . . true
1/x = -(1/-x) . . . . true
x = -(-x) . . . . true
sin(x) = -sin(-x) . . . . true
cos(x) = -cos(-x) . . . . false
e^x = -e^-x . . . . false
|x| = -|-x| . . . . false

on a coordinate plane, point a is located (-2,2) and point b is located at (6,-1). determine the coordinates of the point that is 7/8 of the distance from a to b
The coordinates of the point between points a to b are (5, -5/8)
How to determine the coordinate of the point on the line segment?We have the following endpoints on the segment
A = (-2, 2)
B = (6, -1)
The line ratio is given as the following fraction
Ratio, m : n = 7/8
Express the fraction as a ratio
So, we have
m : n = 7 : 8 - 7
Evaluate the difference
So, we have
m : n = 7 : 1
The coordinate of the point is then calculated as
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
Substitute the known values in the above equation
Point = 1/(7 + 1) * (7 * 6 + 1 * -2, 7 * -1 + 1 * 2)
Evaluate the products in the above equation
So, we have
Point = 1/8 * (42 -2, -7 + 2)
Evaluate the sum and the difference
So, we have
Point = 1/8 * (40, -5)
Evaluate the products
So, we have
Point = (5, -5/8)
Hence, the coordinates of the point that is 7/8 of the distance from a to b are (5, -5/8)

The domain for the rational function is the set of all real numbers except for 8, this is written as:
{x | x ∈ R, x≠8}
How to find the domain of the given function?
For any function f(x), the domain is the set of the possible inputs.
In this case, we have the rational function:
f(x) = (x - 3)/(x - 8)
Now, we start by assuming that the domain is the set of all real numbers, and then we remove all the problematic values.
Now, we can't divide by zero, so the value of x that makes the denominator zero needs to be removed, that is such:
x - 8 = 0
x = 8
So the domain is the set of all real numbers except for 8, this is written as:
