Linear Function
Step-by-step explanation:
Formula: y = 4x - 2
Plug in the values of x or y for each ordered pair:
y = 4(0) - 2
y = 0 - 2
y = -2
(0, -2)
y = 4(-2) - 2
y = -8 - 2
y = -10
(-2, -10)
14 = 4x - 2
12 = 4x
3 = x
(3, 14)
-14 = 4x - 2
-12 = 4x
-3 = x
(-3, -14)
What type of function is it?
Linear function
Why is it a linear function?
Refer back to the original formula given: y = 4x - 2. This is in slope-intercept form, or y = mx + b. This specific format informs graphers the line will be straight, or linear. You can also graph all of the ordered pairs to obtain a visual of a straight line, proving this function to be linear.
#1
y=4(0)-2y=-2So pair is

#2
y=4(-2)-2y=-10Pair is (-2,-10)
#3

Answer:
126.5
Step-by-step explanation:
The polygon is made up of a rectangle and a triangle.
rectangle: 11 cm by 8 cm
triangle: base = 11 cm; height = 7 cm
area = LW + bh/2
area = 11 cm * 8 cm + (11 cm)(7 cm)/2
area = 88 cm^2 + 77/2 cm^2
area = 88 cm^2 + 38.5 cm^2
area = 126.5 cm^2
A rectangle’s length is 9 more than 4 times its width. The area of the rectangle is 90 square inches. What is the width of the rectangle?
Answer:
15/4 in or 3.75 in
Step-by-step explanation:
Find your equations:
L = 4w + 9 in
A = L*w = 90 in^2
Substitute L:
L*w = 90 in^2 <-- L = 4w + 9
(4w + 9in)w = 90 in^2
4w^2 in^2 + 9w in = 90in^2
Solve Simultaneously:
w = -6 in, 15/4 in
Width is positive so it is 15/4 in or 3.75 in.
Double check:
(4w + 9in)w = 90 in^2
(4*3.75in + 9in)(3.75in) = 90 in^2

Write a function for the line with a slope of −14 that passes through the point (4, 5)
Answer:
y = -14x + 61
Step-by-step explanation:
y = mx + b
First, we can find the slope by reading the question and plugging in the slope of -14 into a slope-intercept formula.
y = (-14)x + b
Now, we need to find the "b" value. We can plug anything we want in for x and y here, but we want the equation for the line that passes through the the point (4,5). Plug in 4 into the x value and 5 into the y value, and solve for b.
5 = (-14)(4) + b
(Flip the equation, so we can solve for b.)
b = 5 - (-14) (4)
(Multiply.)
b = 5 - -56
(Substitute the double minus for a plus sign and add.)
b = 5 + 56
b = 61
Now, plug in your "b" value into our original equation.
FINAL ANSWER:
y = -14x + 61

2/3
Step-by-step explanation:
____ 1 ___ 2 ____ 3
1 ___2 ___ 3 ____ 4

2___3 ___ 4 _____5
|
3___4 ____5 _____6
Winning outcomes : (1,3) ;(2, 2) ;(2, 3);(3, 1) ;(3, 2) ; (3,3)
Probability that a player wins :

Number of winning Outcomes = 6
Total possible outcomes = 9
Probability that a player wins = 6 / 9 = 2/3
The diagonal of a cube is 20 cm. Identify the length of an edge. Round to the nearest tenth, if necessary.
answers:
20 cm
14.1 cm
13.8 cm
11.5 cm
The length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a cube.
The diagonal of a cube is 20 cm.
Let a be the side length of the cube.
As we know, from the Pythagoras theorem we can calculate the length of the face diagonal.
Pythagoras' theorem can be defined as the square of the hypotenuse in a right-angled triangle equal to the sum of the squares of the other two sides.
Length of a face diagonal = √2a
Length of body diagonal = √3a
√3a = 20 (given)
a = 20/√3
a = 20/1.732
a = 11.5 cm
Thus, the length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.

So say someone did 1000 push ups a day for 8 years 2920 days in 8 years and you want to do the same amount but in 2 months how many would you have to do a day
Answer:
48,667 if you round it..
Step-by-step explanation:
1000x2920 = 2,920,000
divided by 2 months
2,920,000/2 = 1,460,000
and theres 30-31 days in a month
1,460,000/30 = 48,666.67
5) Crystal wants to consolidate her bills into 1 smaller monthly payment. She has a total of
$23,000 worth of debt. If she consolidates with a personal loan, she can choose between a 5
year or 8 year loan at 6.75% APR. How much more interest will she pay if she chooses 8
years instead of the 5 year loan?
Answer:
The amount more in interest she will pay if she choose 8 years instead of 5 years loan is approximately $2,665.92
Step-by-step explanation:
The total worth of debt Crystal has. P = $23,000
The options on the number of years for which the loans for consolidation are available, t = 5 and 8 years
n = 12 × t = The number of monthly payment = 12×5 = 60 or 12 × 8 = 96
The annual percentage rate of the loans, r = 6.75% = 0.0675
The monthly payments, 'M', Crystal pays is given as follows;
[tex]M = \dfrac{P \cdot \left(\dfrac{r}{12} \right )\cdot \left ( 1 + \dfrac{r}{12} \right)^{n} }{\left ( 1 + \dfrac{r}{12} \right)^{n} - 1}[/tex]
When n = 60, we get;
[tex]M = \dfrac{23,000 \times \left(\dfrac{0.0675}{12} \right )\cdot \left ( 1 + \dfrac{0.0675}{12} \right)^{60} }{\left ( 1 + \dfrac{0.0675}{12} \right)^{60} - 1} \approx 452.72[/tex]
The total amount payed, A = M × n
∴ The total amount payed when n = 60 is, A₅ = 452.72 × 60 = 27163.2
A₅ ≈ $ 27,163.2
The interest on the loan, I₅ = A₅ - P
∴ I₅ = $27,163.2 - $23,000 = $4,163.2
When n = 80, we get;
[tex]M = \dfrac{23,000 \times \left(\dfrac{0.0675}{12} \right )\cdot \left ( 1 + \dfrac{0.0675}{12} \right)^{96} }{\left ( 1 + \dfrac{0.0675}{12} \right)^{96} - 1} \approx 310.72[/tex]
∴ The total amount payed when n = 80 is, A₈ = 310.72 × 96 = 29,829.12
A₈ = $ 29,829.12
The interest on the loan, I₈ = A₈ - P
∴ The interest on the loan, I₈ = 29,829.12 - 23,000 = 6,829.12
The interest Crystal pays when takes the loan for 8 years, I₈ = $6,829.12
Therefore, the amount more interest she will pay if she choose 8 years instead of 5 years loan, ΔI = I₈ - I₅
ΔI = $6,829.12 - $4,163.2 = $2,665.92
The amount more interest she pays if she choose 8 years instead of 5 years loan, ΔI = $2,665.92.

Answer:
8) 50°, 50°, 130°, 130°10) 120°Step-by-step explanation:
Ex 8Adjacent interior angles of a parallelogram are supplementary
Let the small angle is x, the other angle is:
2x + 30°The sum of two angles is 180°
x + 2x + 30° = 180°3x = 150°x = 50°The angles are 50°, 50°, 130°, 130°
Ex 10Sum of interior angles of a pentagon is:
S = 180°(5 - 2) = 540°Two of the angles are supplementary, so they sum to 180°
The sum of the remaining 3 angles is:
3x = 540° - 180°3x = 360°x = 120°Each of the congruent angles is 120°

What is a linear and non-linear trend?
9514 1404 393
Explanation:
Linear trend
A linear trend is one that is best approximated by a straight line. Sometimes we use a straight-line approximation, even when it may not be a very good fit, because we are only interested in the sign of the slope, or its approximate magnitude. The parameters of a linear trend are about the easiest to calculate (though it doesn't matter much if an appropriate tool is used).
__
Non-linear trend
A non-linear trend is one that is best approximated by a curve other than a straight line. Trig functions (sine, cosine), exponential functions, quadratic functions are often used. Non-linear trends are not restricted to these kinds of functions.
