Linear Modeling
Some events can be modeled as linear functions. If there is a situation where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.
The linear function can be expressed in the slope-intercept format:
[tex]y=mx+b[/tex]
The event into consideration is the number of pages of a book left to read by Shyryia.
We know that for x=1.5 hours, she had y=402 out of the total 480 pages left to read. This is the point ( 1.5, 402 ). The other point is not obvious but can be inferred by context. If she hasn't used any time to read (x=0), then she would have y=480 pages left to read. This is the point (0,480).
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Substituting the given points:
[tex]\displaystyle y-402=\frac{402-480}{1.5-0}(x-1.5)[/tex]
[tex]\displaystyle y-402=\frac{-78}{1.5}(x-1.5)[/tex]
Operating:
[tex]y-402=-52(x-1.5)[/tex]
[tex]\mathbf{y=-52x+480}[/tex]
Answer:
-52x+480.

lg(5x+10)+2lg3=1+lg(4x+12)
need them fast with steps
Answer:
x=6
Step-by-step explanation:
log(5x+10)-log(4x+12)=1-2log(3)
log(5x+10/4x+12)=1-2log(3)
log(5x+10/4x+12)=log(10)+log(3^-2)
log(5x+10/4x+12)=log(10×3^-2)
log(5x+10/4x+12)=log(10×1/9)
log(5x+10/4x+12)=log(10/9)
5x+10/4x+12=10/9
9(5x+10)=(4x+12)10
45x+90=40x+120
5x=30
x=6

- A rectangular pool has an area of 140 square feet. If the length of the
pool is 16 feet, what is its width?
Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
Answer:
8.75 ft
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet

Tyler incorrectly says that the constant term of (x + 4)(x - 4) is zero.
a. What is the correct constant term?
b. What is Tyler's mistake? Explain your reasoning.
Answer:
a. -16 is the constant
b.if you expand the equation it would be x^2-16, and the constant is -16
Solving the expression (x + 4)(x - 4) ; the constant term in the expression is - 16 and not 0
To solve, we need to expand the expression : (x+4)(x-4)
Expanding the expression :
(x + 4)(x - 4)
Opening the bracket :
x² - 4x + 4x - 16
x² - 16
The constant term in the expression, is - 16 as it is the value without a variable.
Therefore, Tyler's mistake is incorrectly stating that the constant value is 0 instead of - 16

What is f(x)= 3x+ 13(17x-7) if x equals 4?
Answer:
805
Given:
x=4
Step-by-step explanation:
f(x) = 3x + 13(17x-7)
f(x) = 3 × 4 + 13(17 × 4 - 7)
f(x) = 12 + 13(68 - 7)
f(x) = 12 + 13 × 68 - 13 × 7
f(x) = 12 + 884 - 91
f(x) = 12 + 793
f(x) = 805

Find all the missing elements
Answer:
[tex] b = 5.5 [/tex]
[tex] c = 11.2 [/tex]
Step-by-step explanation:
Given:
A = 96°
B = 25°
C = 59°
a = 13
Required:
b and c
SOLUTION:
Use Sine Rule to find the measure of a and b, respectively.
✍️Thus, to find b, use,
[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]
Plug in the values
[tex] \frac{13}{sin(96)} = \frac{b}{sin(25)} [/tex]
Multiply both sides by sin(25)
[tex] \frac{13}{sin(96)} \times sin(25) = \frac{b}{sin(25)} \times sin(25) [/tex]
[tex] \frac{13 \times sin(25)}{sin(96)} = b [/tex]
[tex] b = 5.5 [/tex] (nearest tenth)
✍️To find c, use,
[tex] \frac{a}{sin(A)} = \frac{c}{sin(C)} [/tex]
Plug in the values
[tex] \frac{13}{sin(96)} = \frac{c}{sin(59)} [/tex]
Multiply both sides by sin(59)
[tex] \frac{13}{sin(96)} \times sin(59) = \frac{c}{sin(25)} \times sin(59) [/tex]
[tex] \frac{13 \times sin(59)}{sin(96)} = c [/tex]
[tex] c = 11.2 [/tex] (nearest tenth)

General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch?
A. P(x) ≥ $8.00
B. x is all real numbers
C. x ≥ 0, where x is non-negative
D. x ≥ 0, x is an integer
Given:
Total cost P(x) as a function of the number of tickets, x is
[tex]P(x)=x+8[/tex]
To find:
The domain for visiting and riding rides at Paul’s Pumpkin Patch.
Solution:
Domain is the set of input values.
Here, domain is x and it represents the number of tickets.
We know that, number of tickets cannot be negative or decimal or fraction vales. So, x must be non-negative and integer value.
Domain = x ≥ 0, x is an integer
Therefore, the correct option is D.

Use the table to find the residual points. A 4-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled given with entries negative 0.7, 2.3, 4.1, 7.2, 8. The third column is labeled predicted value with entries negative 0.28, 1.95, 4.18, 6.41, 8.64. The fourth column is labeled residual value with all entries blank. Which residual plot is the correct one for the data? A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph. A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph. A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph. A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph.
Answer:
B
Step-by-step explanation:
residual is the given - predicted
residual 1: -0.42
residual 2: 0.35
so on and so forth
B matches up with the first two coordinates
The residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
The residual = actual—predicted
We have given:
X Given Predicted Residual value
1 0.7 0.28 0.42
2 2.3 1.95 0.35
3 4.1 4.18 -0.08
4 7.2 6.41 0.79
5 8 8.65 -0.65
Thus, the residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.
