which system of linear inequalities is represented by the graph?
a) y ≥ 1/3x + 3 and 3x - y > 2
b) y ≥ 1/3x + 3 and 3x - y > 2
c) y ≥ 1/3x + 3 and 3x + y > 2
d) y ≥ 1/3x + 3 and 2x - y > 2
Answer:
A and B look identical, so perhaps there was a typo?
The equations are:
[tex]y\geq1/3x+3[/tex]
[tex]3x-y>2[/tex]
Step-by-step explanation:
To find the system of linear inequalities represented by the graph, we need to find the equation of each line.
Red Line:
To find the equation of the red line, we need to first find the slope and the y-intercept.
Let's pick two points from the red line. We can use (0, 3) and (3, 4).
The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 3) be (x₁, y₁) and let's let (3, 4) be (x₂, y₂). So, our slope is:
[tex]m=\frac{4-3}{3-0}[/tex]
Subtract:
[tex]m=1/3[/tex]
So, our slope is 1/3.
Note that (0,3) is also our y-intercept. So, our y-intercept is y=3.
Now, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
Substitute 1/3 for m and 3 for b. This yields:
[tex]y=1/3x+3[/tex]
Now, we need to determine which sign to use.
Note that the red line is not dotted, meaning we need "or equal to."
Also, note that the shaded region is above our line. In other words, y must be greater than our equation.
So, our sign is "greater than or equal to."
This, the red inequality is represented by the equation:
[tex]y\geq1/3x+3[/tex]
Blue Line:
Again, let's first find the slope and the y-intercept.
We can use the points (0, -2) and (1,1). Let (0,-2) be (x₁, y₁) and let's let (1, 1) be (x₂, y₂). Substitute them into the slope formula:
[tex]m=\frac{1-(-2)}{1-0}[/tex]
Evaluate:
[tex]m=3/1=3[/tex]
So, our slope is 3.
(0, -2) is also our y-intercept. So, our y-intercept is y=-2.
Again, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Substitute 3 for m and -2 for b:
[tex]y=3x-2[/tex]
Now, we need to find our inequality sign.
Notice that the line is dotted. So, we won't have any "or equal to."
Also, notice that our shaded region is below our line. Thus, y is less than our equation. Therefore:
[tex]y<3x-2[/tex]
However, all of our choices are in standard form. So, we need to convert this to standard form.
To do so, subtract 3x from both sides:
[tex]-3x+y<-2[/tex]
The first term is traditionally positive. So, multiply both sides by -1. Since we're multiplying by a negative, flip the inequality sign:
[tex]3x-y>2[/tex]
We can see that the answer choice that matches this is A (or B?)
And we're done!
Answer: A and B are identical so pick one of them
Step-by-step explanation:
-2 (-x + 4) + 4x - 3 = 31
Answer:
The value of x is 7.
Step-by-step explanation:
First, you have to expand the brackets and then, solve it :
[tex] - 2( - x + 4) + 4x = 31[/tex]
[tex]2x - 8 + 4x - 3 = 31[/tex]
[tex]6x - 11 = 31[/tex]
[tex]6x = 31 + 11[/tex]
[tex]6x = 42[/tex]
[tex]x = 42 \div 6[/tex]
[tex]x = 7[/tex]
in a standard deck of t2 playing cards, there are 4 aces, 4 kings, 4 queens, and 4 Jacks. All other cards have number values. the kings, queens, and Jack's are called face cards. You are dealt 2 cards in sequence. Calculate the probability of being dealt 2 face cards. write your answer as a decimal to the nearest hundredth
=======================================================
Explanation:
There are 12 face cards (4 kings+4 queens + 4 jacks) out of 52 total.
The probability of getting one face card is 12/52 = 3/13
After a face card is dealt, we have 12-1 = 11 face cards left out of 52-1 = 51 total. The probability of getting another face card is 11/51.
Multiply the fractions found. Use a calculator.
(3/13)*(11/51) = 0.04977
This rounds to 0.05 when rounding to two decimal places (nearest hundredth)
Note: this assumes you do not put the first card back or replace the first card with an equivalent card.

5 The cost of an adult's ticket into a theme park is $a.
The cost of a child's ticket into the same theme park is $c.
Write an expression for the total cost for each groun.
Answer:
Total Cost (in dollars) = a + c
Step-by-step explanation:
Algebra
When mathematics quantities are generalized into letters or variables, then we are dealing with algebra.
We are said the cost of an adult's ticket into a theme park is $a and a child's ticket costs $c. Since both quantities are unknown, we must treat them as variables and use the same logic procedure to solve the problem as if they were numbers.
The total cost for an adult and a child is the sum of both individual costs, thus
Total Cost (in dollars) = a + c
If a ⊥ y and x ∥ y, then _____
x ⊥ a.
x ∥ z.
a ∥ b.
a ⊥ z.
Answer:
A⊥X
Since
A is perpendicular to Y
A⊥YAnd, X is parallel to Y
X || Y
That implies that A must be also perpendicular to X
A⊥X
Which means that they have the same slope (same inclination)

Amanda buys 4 tickets to a baseball game for $24. Which equation shows the closest estimate of the total amount Amanda spent?
Amanda spent 6 dollars for each ticket for a baseball game.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Total money spent = $24
Number of the tickets = 4
SO cost of each ticket will be:-
Cost = 24 / 4 =6
Therefore Amanda spent 6 dollars for each ticket for a baseball game.

Today, Petland sold 5 times as
many cats as dogs. If a total of
48 cats and dogs were sold, how
many dogs were sold?
Answer:
8 dogs
Step-by-step explanation:
Petland sold 5 times as many cats as dogs
A total of 48 cats and dogs were sold
Let c represent the number of cats sold
Let d represent the number of dogs sold
c + d= 48..........equation 1
Since 5 times as many cats as dogs were sold
c= 5d
Substitute 5d for c in equation 1
5d + d= 48
6d= 48
Divide both sides by the coefficient of d which is 6
6d/6 = 48/6
d= 8
Hence 8 dogs were sold
