X = 3
y = 2
The x-intercept is at (0,3), and the y-intercept is at (2, 0).
Answer:
Wrong order!
Step-by-step explanation:
There's a reason why coordinates are called an "ordered pair", and for every point (a, b) a is the x coordinate and b is the y coordinate. The calculations are correct, the way reporting them are not: the point should be (3.0) and (0,2) - in fact, all points on the x axis are of the form (p, 0) and all points on the y axis of the form (0,q)

When determining domain it is important to work from
Answer:
use graphs
Step-by-step explanation:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

If the length of each side of a cuboid decreases by 20%, find the percentage decrease in its volume.
Solution : (Identify the ratio of the length of one edge of the original cuboid and the length of one edge of the new cuboid)
Answer:
Step-by-step explanation:
(1+25 /100) (1-20/100) (1-50/100) <1
5/4 x 4/5 x 1/2 <1
Decrease in volume (in percent)
(1+25 /100) (1-20/100) (1-50/100) x 100
=48.8%

Answer:
y + 5x = -7
Step-by-step explanation:
Hello there?
y + 3 = -5(x + 2)
LHS
Open the brackets
= -5x - 10
RHS remains
Combine the two:
y + 3 = -5 - 10
Collecting the like terms and taking the value of x to the LHS
=> y + 5x = - 7

1 7/8 divided by 2 2/5 if give good response = brainlist
Answer:
75/96 or in its simplest form, 25/32
Step-by-step explanation:
1. Convert both fractions into improper fractions
1 7/8 becomes 15/8 (1 × 8 = 8, 8 + 7 = 15)2 2/5 becomes 12/5 (2 × 5 = 10, 10 + 2 = 12)2. Use KFC
Keep the first fraction the sameFlip the second fractionChange the sign from ÷ to ×15/8 ÷ 12/5 = 15/8 × 5/12
15 × 5 = 758 × 12 = 9675/96 = 25/32 (divide the numerator and denomiator by 3)Hope this help!

1. Mitch Hart's gross pay for this week is $425.78. He is single and claims 2 6 points
allowances. Using the percentage method of withholding, what amount
will Mitch's employer withhold from his pay for federal income tax?
Percentage Method of Withholding - Single Person
Each weekly allowance is $63.46.
Weekly Taxable The amount of income tax to
Wage
withhold is
Over But not
over
$51.00 $195.00 S0.00 plus (10% of the excess
over $51.00)
195.00 645.00 $14.40 plus (15% of the excess
over $195.00)
645.00 1482.00 $81.90 plus (25% of the excess
over $645.00)
Using the percentage method, the amount that Mitch's employer is going to withhold is $29.979
The total wage payment usually received by Mitch monthly is = $425.78Each weekly allowance is $63.46, It is noted that Mitch claims two allowances = $63.46 × 2= $126.92Now, the amount subject to withholding from his total wage payment is;
= $(425.78 - 126.92)= $298.86Provided that the weekly taxable wage is more than $195 but not up to $645; Then, by using the percentage method, the Federal income tax can be computed as:
= 15% of $(298.86 - 195) + $14.40= 15% of $103.86 + $14.40= $15.579 + $14.40= $29.979Therefore, we can conclude that the amount that Mitch's employer is going to withhold is $29.979

A point $P$ is randomly selected from the square region with vertices at $(\pm 2, \pm 2)$. What is the probability that $P$ is within one unit of the origin
If P = (X, Y) is a point in the given square, then X and Y are i.i.d random variables each with distribution
[tex]\displaystyle P(X = x) = \begin{cases}\dfrac14 & \text{if } -2 \le x \le 2 \\ 0 & \text{otherwise}\end{cases}[/tex]
and so the joint density of X and Y is
[tex]\displaystyle P(X = x, Y = y) = \begin{cases}\dfrac1{16} & \text{if }-2 \le x \le 2 \text{ and } -2 \le y \le 2 \\ 0 &\text{otherwise}\end{cases}[/tex]
We want to find P(X² + Y² ≤ 1). Points that satisfy this inequality lie in the set
R = {(x, y) : -1 ≤ x ≤ 1 and -√(1 - x²) ≤ y ≤ √(1 - x²)}
but we can more easily describe the region in polar coordinates by setting
x = r cos(t) and y = r sin(t)
so that the set R is identical to
R' = {(r, t) : 0 ≤ r ≤ 1 and 0 ≤ t ≤ 2π}
Integrate the joint density over R' :
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \iint_R \frac1{16} \, dx \, dy[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \iint_{R'} \frac r{16} \, dr \, dt[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \int_0^{2\pi} \int_0^1 \frac r{16} \, dr \, dt[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \int_0^{2\pi} \frac{1^2 - 0^2}{32} \, dt[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \frac1{32} \int_0^{2\pi} dt[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \frac{2\pi-0}{32}[/tex]
[tex]\displaystyle P(X^2 + Y^2 \le 1) = \boxed{\frac{\pi}{16}}[/tex]

equation of the line that passes through the points (7, 6) and (-2, -3)?
Answer:
y=x-1
Step-by-step explanation:
Hi there!
We want to find the equation of the line that passes through the points (7, 6) and (-2, -3)
There are 3 ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a pointStandard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0, and a cannot be negativeThe most common (and usually, the easiest way) would be slope-intercept form, so let's write it that way
First, we'll need to find the slope of the line
The slope can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have two points, which is needed, but let's label their values in order to avoid any confusion:
[tex]x_1= 7\\y_1=6\\x_2=-2\\y_2=-3[/tex]
Now substitute these values into the formula to find the slope (m):
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-3-6}{-2-7}[/tex]
Subtract the numbers
m=[tex]\frac{-9}{-9}[/tex]
Divide
m=1
The slope of the line is 1
So far, we can write the equation of the line as this:
y=1x+b, or y=x+b
We'll need to find b
As the equation passes through both (7,6) and (-2, -3), we can use either one of them to solve for b
Taking (7, 6) for instance, substitute 7 as x and 6 as y:
6=1(7)+b
Multiply
6=7+b
Subtract 7 from both sides
-1=b
Now substitute -1 as b:
y=x-1
Hope this helps!
