Write an equation of the line graphed below in slope-intercept form.
The equation of the line is y = (2/3)x -1
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
From the given graph, we have two points (0, 1) and (3,3)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
y - 1= (3 -1 ) / (3 -0) x (x -0)
y = (2/3)x -1
The equation of the line is;
y = (2/3)x -1 {equation 1}
Slope intercept form of a line is
y = mx + b {equation 2} ,
where m is the slope and b is the y-intercept.
On comparing the equation (1) and (2) we get
It means,
Slope = 2/3
y-intercept = -1
Therefore, the equation of the line is y = (2/3)x -1

For values of h very close to 0, which function best approximates (tan(x+5)-tan x) / h
Answer:
[tex]sec^2(x)[/tex]
Step-by-step explanation:
This just means, what is the derivative of tan(x)The function that best approximates the given situation is sec²x.
We have to find
[tex]\lim_{h \to\00} \frac{tan(x+h)-tan x}{h}[/tex]
Since the given expression reduces to 0/0 form when we apply the limits
So, let us apply the L'hospital rule
What is the L'hospital rule to find a limit?L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.
So, after differentiating the numerator as well as the denominator of the given expression with respect to h we get
[tex]\lim_{h \to\00} \frac{sec^2(x+h)-0}{1}[/tex]
[tex]= lim_{h \to\00} \frac{sec^2(x+0)}{1}\\\\= sec^2x[/tex]
Therefore, the function that best approximates the given situation is sec²x.

Tony hit 9 out of 15 pitches at baseball practice yesterday. What percentage of the pitches did Tony NOT hit?
Answer:
5%
Step-by-step explanation:
Answer:
40%
Step-by-step explanation:
using the box method,
multiply 9 × 100
= 900 and divide 900 by 15
900 ÷ 15 = 60%
60% is the amount of pitches he hit
100% - 60% = 40%
he missed 40%

Marcus is considering two car rental plans. Plan A can be modeled with the equation C=30d, and Plan B can be modeled with the equation C=25d + 15, where C represents the cost in dollars and d represents the number of days a car is rented. Which statement would justily selecting Plan B instead of Plan A
A.Marcus rent a car for 1 day
B.Marcus rent a car for 2 days
C.Marcus rent a car for 3 days
D.Marcus rent a car for 5 days
Answer:
D. Marcus rent a car for 5 days
Step-by-step explanation:
You can solve this by simply plugging the answer choices into the variable d for both equations and comparing the total costs.
When you plug in 5 days you get:
Plan A
C = 30 x 5
C = 150
Plan B
C = 25 x 5 + 15
C = 140
The cost is less for Plan B in this case, so it is better to use Plan B when renting for 5 days.

Given that Paula has 35 unique puzzle pieces
So, the method of organizing possible pictures can she create dependent on each other to succeed.
There is an arrangement process
It is equal to the permutation of 35 numbers
⇒ ³⁵P₃₅
The formula of ⁿPₓ = n!/(n-x)!
⇒ 35!/(35-35)!
⇒ 35!/0! [∵ 0! = 1]
⇒ 35!

Consider the line y = 4x-3.
Find the equation of the line that is perpendicular to this line and passes through the point (3, -3).
Find the equation of the line that is parallel to this line and passes through the point (3, -3).
Answer:
perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
parallel line: y = 4x - 15
Step-by-step explanation:
Perpendicular line:
A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].
Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.
-3 = - [tex]\frac{1}{4}[/tex](3) + b
-3 = - [tex]\frac{3}{4}[/tex] + b
Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.
-[tex]\frac{9}{4}[/tex] = b
Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
Parallel Line:
A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.
-3 = 4(3) + b
-15 = b
Now you can write the equation, y= 4x -15

Step-by-step explanation:
The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation [tex]y= \frac{1}{2}x+2[/tex]

Answer:
1) The amount the family spent on pizza is $300
2) The amount the family spent on soda is $43.2
3) The amount the family spent in all is $343.2
Step-by-step explanation:
The number of pizzas bought by the family = 24
The price of each pizza = $12.50
The number of bottles of soda the family bought = 36
The price of each bottles of soda = $1.20
1) The amount the family spent on pizza = 24 × $12.50 = $300
2) The amount the family spent on soda = 36 × $1.20 = $43.2
3) The amount the family spent in all = The amount the family spent on pizza + The amount the family spent on soda
∴ The amount the family spent on soda = $300 +$43.2 = $343.2.
