On a coordinate plane, a solid straight line has a positive slope and goes through (negative 3, negative 5) and (0, negative 4). Everything to the right of the line is shaded.
Which linear inequality is represented by the graph?
y ≥ One-thirdx – 4
y ≤ One-thirdx – 4
y ≤ One-thirdx + 4
y ≥ One-thirdx + 4
Since everything to the right of the line is shaded, the linear inequality which represents the graph is equal to: A. y ≥ 1/3x - 4.
How to determine the linear inequality?In order to determine the linear inequality which represents the graph, we would find the slope of the given points.
Mathematically, the slope of a straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope = \frac{-4\;-\;(-5)}{0\;-\;(-3)}\\\\Slope = \frac{1}{3}[/tex]
Slope = 1/3.
From the standard equation, we have:
y - y₁ = m(x - x₁)
y - (-5) = 1/3(x - (-3))
y + 5 = 1/3x + 1
y = 1/3x + 1 - 5
y = 1/3x - 4
y ≥ 1/3x - 4.

Determine the domain of (g ∘ f)(x) if f (x) = x2 + x − 3 and g of x is equal to 1 over the quantity x plus 1 end quantity period {x ∈ ℝ| x ≠ −1} {x ∈ ℝ| x ≠ −2, 1} {x ∈ ℝ| x ≠ −2, −1, 1} {x ∈ ℝ}
The domain of gof(x) is {x ∈ ℝ| x ≠ −2, 1} .
What is domain?The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
given function:
f(x) = x² + x -3
g(x) = 1/x+1
Now, solving the equation
gof = g(f(x))
=g( x² + x -3)
=1/(x² + x -3)+1
=1/ x² + x -2
= 1/ x² +2x - x -2
= 1/ x( x+ 2) - (x +2)
=1/ (x+2)(x-1)
Hence, the domain of gof(x) is {x ∈ ℝ| x ≠ −2, 1} .

Step-by-step explanation:
The best way to solve this problem is to simplify each factorial one by one!
Starting at the numerator, the factorial for 2! is just 2, while the factorial for 5 is 120.
At the denominator, the factorial of 6! is 720, while the factorial for 3 is 6.
To write this out, we're given: [tex]\frac{(2) (120)}{(720) (6)}[/tex]
Just simply multiply and then divide, and we are given 1/18
The radius of a circle is 5 cm (to the nearest cm). What is the smallest value
that the circumference could have?
Answer: 31 cm.
explanation:
Given, Radius = 5 cm (near to)
this means the radius is near 5 cm. It can be 4.9, 4.99, 4.999.....or 5.01,5.001,5.001...... and so on.
So, the circumference of the circle is given by:-
Circumference = 2× [tex]\pi[/tex] × r
⇒ 2 × 22/7 × 5 (for the smallest value, we'll consider r as 5 and then round off the circumference to the smallest value)
⇒ 220/7 ≈ 31.43 cm
rounding off to the smallest integer, we have
Circumference = 31 cm.
The smallest value that the circumference could have is 10 [tex]\pi[/tex]cm
Using Formula,
Circumference = 2 [tex]\pi \\[/tex] r
Radius = 5 cm
So, C = 2 [tex]\pi[/tex] 5
C = 10 [tex]\pi[/tex]cm
Therefore circumference is 10 [tex]\pi[/tex]cm.

Solve the compound inequality.
0 < 5-2x/3 <5
Answer: The answer is x < 5/2 and x > -5.
Step-by-step explanation:
First you need to separate the inequality and keep x on one side to maintain consistency. For instance the problem-
[tex]\frac{5-2x}{3} > 0\\\frac{5-2x}{3} < 5\\[/tex]
Now solve as normal.
*Note: When dividing a side or multiplying a side by a negative number, the sign of the inequality switches (this will be shown when I do the equation if it doesn't make since how I word it).
[tex]5-2x > 0*3\\5-2x < 5*3[/tex]
[tex]-2x > 0-5\\-2x < 15-5[/tex]
[tex]x < \frac{-5}{-2} =x < \frac{5}{2} \\x > \frac{10}{-2} =x > -5[/tex]
So, x < 5/2 and x > -5.

Find the equation of the line that is perpendicular to y=-2x-9 and contains the points (8,-4)
The slope of the given line is -2, and since perpendicular lines have negative reciprocal slopes, the slope of the line we want to find is 1/2.
Substituting into point-slope form,
[tex]y+4=\frac{1}{2}(x-8)\\\\y+4=\frac{1}{2}x-4\\\\\boxed{y=\frac{1}{2}x-8}[/tex]
Answer:
Equation of line perpendicular to y= -2x-9 is y=x/2-8 .
Step-by-step explanation:
The slope of a line gives the measure of its steepness and direction. The slope of a curve at a point is equal to the slope of the straight line that is tangent to the curve at that point.
The general equation of a line is y = mx + c, where m is the slope of the line and c is the y-intercept. It is the most common form of the equation of a straight line that is used in geometry.
The product of slopes of two perpendicular lines gives (-1).
m1m2=(-1)
(-2)m2=(-1)
m2=1/2
y=m2x+c

Given the function h(x) = 3(5)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average rate of change of each section. (4 points) Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points) (10 points)
Answer:
For section A, the average rate of change is 12. For section B, the average rate of change is 300. The average rate of change in Section B is greater than Section A by 25. The rate of change keeps on increasing because the slope of the function is increasing.
Step-by-step explanation:
Concept: For a function f(x), the rate of change is given by [tex]\frac{f(x_{2})-f(x_{1}) }{x_{2}-x_{1} }[/tex]. Given function is h(x) = 3(5∧x).
For x = 0 to x = 1, the value of function would be f(0) = 3 to f(1) = 15.
The rate of change would be (15-3) / (1-0) = 12.
For x = 2 to x = 3, the value of function would be f(2) = 75 to f(3) = 375.
The rate of change would be (375-75) / (3-2) = 300.
The average rate of change in Section B is greater than Section A by
300 / 12 = 25.
Looking at the function, that is h(x) = 3(5∧x), we see that this function is an increasing function. The slope of an increasing function keeps on increasing with the value of x. The rate of increase is also a slope. That is why the rate keeps on increasing.
