Which linear inequality is represented by the graph?
O y s 2x + 4
Oys2x+3
O y z 2 / 3x + 3
O y 22x + 3
Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the boundary line passes through two point (0,3) and (2,4). So, the equation of boundary line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{4-3}{2-0}(x-0)[/tex]
[tex]y-3=\dfrac{1}{2}(x)[/tex]
[tex]y=\dfrac{1}{2}x+3[/tex]
The shaded area lies below the boundary line and the boundary line is a solid line. So, the sign of inequality must be ≤.
The required inequality is
[tex]y\leq \dfrac{1}{2}x+3[/tex]
Therefore, the correct option is B.

What is the area of the following circle?
Either enter an exact answer in terms of pie or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
153.86 units²
Step-by-step explanation:
From the question given above, the following data were obtained:
Pi (π) = 3.14
Radius (r) = 7 units
Area (A) =?
The area of a circle can be obtained by using the following formula:
A = πr²
A = 3.14 × 7²
A = 3.14 × 49
A = 153.86 units²
Thus, the area of the circle is 153.86 units²

If g(x)is the inverse of f(x) and f (x) = 4 x + 12, what ig(x)
g (x) = 12 x + 4

g (x) = one-fourth x minus 3
Answer:
The inverse of a given function
d) [tex]g(x) = \frac{1}{4} x - 3[/tex]
Step-by-step explanation:
Explanation:-
Given that f(x) = 4x + 12
let y = 4 x + 12
4 x = y - 12
[tex]x = \frac{y-12}{4}[/tex]
[tex]x = \frac{1}{4} y - 3[/tex]
we know that y = f(x)
⇒ x = f⁻¹(y)
[tex](f^{-1} y) = \frac{1}{4} y - 3[/tex]
Put replace 'y' in 'x'
[tex](f^{-1} x) = \frac{1}{4} x - 3[/tex]
Final answer:-
The inverse of a given function
[tex]g(x) = \frac{1}{4} x - 3[/tex]

Recall that for use of a normal distribution as an approximation to the binomial distribution, the conditions np greater than or equal to 5 and nq greater than or equal to 5 must be met. For p= 0.9, compute the minimum sample size needed for use of the normal approximation. Round your answer to the next whole number.
The minimum sample size needed for use of the normal approximation is =
Answer:
The minimum sample size needed for use of the normal approximation is 50.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 5
n(1-p) >= 5
In this question, we have that:
p = 0.9
Since p > 0.5, it means that np > n(1-p). So we have that:
[tex]n(1-p) \geq 5[/tex]
[tex]n(1 - 0.9) \geq 5[/tex]
[tex]0.1n \geq 5[/tex]
[tex]n \geq \frac{5}{0.1}[/tex]
[tex]n \geq 50[/tex]
The minimum sample size needed for use of the normal approximation is 50.
3x-5y=15 in slope intercept form
Answer:
I think the answer will be y=3/5x-3
Answer:
y = 3/5x - 3
Step-by-step explanation:
Slope-intercept form is y = mx + b.
For this question, all you need to do is move some stuff around!
In slope intercept form, the x is on the right side, so you would first subtract x from both sides.
3x - 5y = 15
Next, you would divide both sides of the equation by -5 to get y by itself.
-5y = 15 - 3x
Finally, rearrange the equation. y = mx + b
y = -3 + 3/5x
y = 3/5x - 3

–59
–6
Answer:
–59
Step-by-step explanation:
f(x) = -2x - 7
f(x) = -2(-4x + 6) - 7
f(x) = 8x - 12- 7
f(x) = 8x - 19
f(x) = 8(-5) - 19
f(x) = -40 - 19
f(x) = -40 - 19
f(x) = - 59

The sum of two odd consecutive integers is 88. Find the integers.
-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)
use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.
(2n + 1) + (2n + 3) = 88
add like terms.
4n + 4 = 88
4n = 84
n = 21
now plugin.
2(21) + 1
42 + 1
= 43 (the first odd integer)
this means the second one would be 45.
answer: 43 and 45
add them to check:
43 + 45 = 88

Michael and Bill are 238 miles apart, traveling towards each other. If Bill travels 20 mph and Michael travels 14 mph how long until they meet?
Answer:
They will meet in 7 hours.
Step-by-step explanation:
They are traveling toward each other, which means that their relative speed is the sum of their speeds.
Bill travels 20 mph and Michael travels 14 mph
This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.
Michael and Bill are 238 miles apart, how long until they meet?
Each hour, they will be 34 miles closer. How many hours for 238 miles?
1h - 34 miles
x h - 238 miles
By rule of three
[tex]34x = 238[/tex]
[tex]x = \frac{238}{34} = 7[/tex]
They will meet in 7 hours.

Step-by-step explanation:
Jennifer is 40 miles north of her house, and she is driving north on the highway at a rate of 35 miles per
hour.
The slope is ?
The y-intercept is ?
Answer:
The slope is 55.
Step-by-step explanation:
Slope determines the direction and the rate of increase or decrease between the two points on a surface or line.
In the question, it is given initially she is 20 miles north of her house
⇒ When x = 0 the y-coordinate is 20
So, the y-intercept is 20
Now, it is given that the rate of change is 55 miles per hour
Hence, the slope is same as 55 because it is the actual rate of change between the positions of Jennifer with time.
The table shows the average bill totals for given numbers of diners at Simone's restaurant. If the rate is constant and you graph this relationship with the number of people along the x-axis and bill amounts along the y-axis, which points will lie on the line you get?
a. (12, 470)
b. (20, 800)
c. (24, 1,020)
d. (27, 1,080)
e. (28, 1,110)
Answer: B and D
Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080
The point (20 , 800) and ( 27 , 1080 )lies on the line.
Option (b) and (d) is correct.
It is given that average bill totals for given numbers of diners at Simone's restaurant.
To find which points will lie on the line you get.
What is co-ordinate?Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
The rate is constant.
Graph this relationship with the number of people along the x-axis and bill amounts along the y axis.
y = mx + c
=> 40 =m+ c
80 = 2m + c
=> m = 40
40 = 40 + c
=> c = 0
Hence
y = 40x
x = 12 => y = 480
x = 20 => y = 800
x =24 => y = 960
x = 27 => y = 1080
x = 28 => y = 1120
Hence (20 , 800) and ( 27 , 1080 ) point lies on the line
