Decide whether the function is linear or nonlinear using both a table and a graph. (Pls help I don’t understand)
y =3x+2
Answer:
[tex]\huge\boxed{\sf{Linear}}[/tex]
Step-by-step explanation:
Hello.
This function is linear.
Remember, linear functions look like so:
y=mx+b (where m = slope & b = y-intercept)
Is y=3x+2 linear? Sure!
Compare:
y=mx+b
y=3x+2
They look the same, huh? The only difference is that the first one has variables, and the second one has numbers. ;)
Now, what about the graph?
All linear functions have a graph that looks like a straight line.
I hope it helps.
Have a great day.

obtain the area and perimeter of the shaded region
Answer:
area = 132 m²
perimeter = 62 m
Step-by-step explanation:
The easiest way to calculate the area of the shape is to work out the area of the entire rectangle, then subtract the area of the 2 small (white) square:
Area of a rectangle = width x length
⇒ area = 10 x 15 = 150 m²
Area of one square = 3 x 3 = 9
Total area = 150 - 9 - 9 = 132 m²
Perimeter = (2 x 10) + 15 + (9 x 3) = 62 m
Choose the equation that correctly shows the Commutative Property of Multiplication.
6 x 7/8 = 7/8 ÷ 6
6 x 7/8 = 6 x 7/8
6 + 7/8 = 7/8 x 6
6 x 7/8 = 7/8 x 6
The equation which correctly shows the Commutative Property of Multiplication is 6 x 7/8 = 7/8 x 6
What is cummutative property?This is the property which holds when a set of operations are changed but still remain the same value.
Check all that applies:
6 x 7/8 = 7/8 ÷ 6
7/8 ÷ 6
= 8/7 × 6
No
6 x 7/8 = 6 x 7/8
Yes
6 + 7/8 = 7/8 x 6
No
6 x 7/8 = 7/8 x 6
Yes
Therefore, 6 x 7/8 = 7/8 x 6 is the answer because the values were interchanged but still remain the same.

How many 4-digit personal identification numbers are possible if the number cannot contain a zero? a. 5,040 b. 6,561 c. 9,000 d. 10,000.
The count of 4-digit personal identification numbers possible if the number cannot contain a zero is given by: Option B: 6561
What is the rule of product in combinatorics?If a work A can be done in p ways, and another work B can be done in q ways, then both A and B can be done in [tex]p \times q[/tex] ways.
Remember that this count doesn't differentiate between order of doing A first or B first then doing other work after the first work.
Thus, doing A then B is considered same as doing B then A
For the given case, there are 4 digit locks, each of them can be from {1,2,3,4,5,6,7,8,9}
So each one has 9 options to choose from.
Thus, using the rule of product, we get the total possible personal identification numbers as: [tex]9 \times 9 \times 9 \times 9= 6561[/tex]
Thus, the count of 4-digit personal identification numbers possible if the number cannot contain a zero is given by: Option B: 6561

Answer:
b) 130
Step-by-step explanation:
The total of the internal angles of any simple hexagon (six sides) is 720°.

720= 590 + x
720 - 590 = x

Which of the following expressions shows the number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter? a. 21 times 36 superscript 7 b. 26 times 36 superscript 7 c. 26 superscript 5 baseline times 10 superscript 3 d. 36 superscript 8.
The number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter is 26×31⁷.
What is Combination?The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.
[tex]^nC_r = \dfrac{n!}{r!(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
As it is given that the password can only be made with letters or numbers, and we know that there are only 26 letters and there are 10 numbers, therefore, the total option available is 36.
Also, it is given that the first letter of the password can only be made with letters, therefore, there are only 26 options available for the first place in the password.
The number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter,
[tex]= ^{26}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \\\\= 26 \times 31\times 31\times 31\times 31\times 31\times 31\times 31\\\\= 26 \times 31^7[/tex]

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow rainwater to drain.
A cross-section of the road can be represented on a graph using the function,
[tex]f(x) = (x - 16)(x+ 16),[/tex]
Here, x represents the distance from the center of the road, in feet.
This equation can be written as,
[tex]f(x) = (x - 16)^2[/tex]
Now to find the maximum height, find the derivative of the above function as,
[tex]f(x) = (x - 16)^2\\f'(x) = (x - 16)^2\\f'(x)=2(x-16)(1)\\f'(x)=2(x-16)[/tex]
Equate the above equation to zero as,

What is the Area and Perimeter of a Rectangle and Circle?Perimeter of a rectangle = 2(length + width)
Area of a rectangle = length × width
Perimeter of a circle = 2πr
Area of a circle = πr²
What is Area of the composite figure?The figure is made up of two semicircles (1 full circle) and a rectangle.
Area of the composite figure = area of circle + area of rectangle
= πr² + length × width

Answer:
(x - y) = 9
Step-by-step explanation:
**Note: we cannot use similar triangle proportionality, as ΔABC is NOT a right triangle**
Using Pythagoras' Theorem a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right triangle)
Create equations for both smaller interior right triangles using Pythagoras' Theorem:
Larger right triangle
CD² + x² = 17²
⇒ CD² = 17² - x²
Smaller right triangle
CD² + y² = 10²
⇒ CD² = 10² - y²
Equate equations:
CD² = CD²
⇒ 17² - x² = 10² - y²
Given:
AB = 21 and AB = x + y
⇒ x + y = 21
⇒ y = 21 - x
Substitute y = 21 - x into 17² - x² = 10² - y² and solve for x:
⇒ 17² - x² = 10² - (21 - x)²
⇒ 17² - x² = 10² - (441 - 42x + x²)
⇒ 17² - x² = 10² - 441 + 42x - x²
⇒ 289 = 100 - 441 + 42x
⇒ 630 = 42x
⇒ x = 630 ÷ 42
⇒ x = 15
Substitute found value for x into y = 21 - x and solve for y:
⇒ y = 21 - 15 = 6
Finally, substitute found values for x and y into (x - y):
⇒ x - y = 15 - 6 = 9
