2. Is the point (-3,-4) the solution to the system of
equations: SHOW ALL YOUR WORK.
Answers
Answer:
y = 2x + 2
-4 = 2(-3) + 2
-4 = -6 + 2
-4 = -4
y = x - 1
-4 = -3 - 1
-4 = -4
It is the solution
Step-by-step explanation:
Answer: Yes, it is the solution to the system.
=========================================================
Explanation:
The point (-3,-4) means that x = -3 and y = -4 pair up together.
Let's plug those values into the first equation and simplify
y = 2x+2
-4 = 2(-3)+2 .... replace x with -3; replace y with -4
-4 = -6+2
-4 = -4 ... we get a true equation
Let's repeat for the other equation as well
y = x-1
-4 = -3-1
-4 = -4 .... this is also true
Since both equations are true, this means (-3,-4) is the solution to the system. The two lines intersect at (-3,-4).
How to know when a parallelogram is a rectangle

Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to know when a parallelogram is a rectangle
There are some properties to be satisfied by the parallelogram to know it is a rectangle
If the parallelogram in question has diagonals that are equal in length, meaning that the by are congruent, then we can say is it a rectangle
Also, the parallelogram must contain four right angles for use to say it is a rectangle
Find the value of x in each case. Give reasons to justify your solutions! XW ∥ YZ
Answers
Answer:
The answer is "19".
Step-by-step explanation:
In this question, the graph file is missing which is defined in the attached file please find it.
When YZ and XW were identical,
[tex]\angle XWY =\angle WYZ \ \ \text{(Alternate Angles)}[/tex]
[tex]\angle XWY = 2x[/tex]
Because the angles are all 180 degrees in either a triangle:
[tex]\to (3x - 5) + 90 + 2x = 180\\\\\to 3x - 5 + 90 + 2x = 180\\\\ \to 5 x + 85= 180 \\\\ \to 5 x = 180-85 \\\\ \to 5x = 95 \\\\ \to x= \frac{95}{5} \\\\ \to x = 19[/tex]
The answer above is accually correct, but always remember when submitting your answer to always put the degrees sign.

P = x + 6y
subject to the following constraints:
(2x + 4y < 10
X + 9y < 12
x > 0
y0
P = [?]
Answers
Answer:
(3, 1)
Step-by-step explanation:
Given the following constraints:
2x + 4y ≤ 10
x + 9y ≤ 12
x ≥ 0
y ≥ 0
We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.
From the graph, the following points satisfy the constraints:
(0,0) , (3,1) , (0,4/3) , (5,0)
Given that:
P = x + 6y
For (0, 0): P = x + 6y = 0 + 6(0) = 0
For (3, 1): P = x + 6y = 3 + 6(1) = 9
For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8
For (5, 0) P = x + 6y = 5 + 6(0) = 5

The graph shows the cost of buying tickets to a concert.
a. What does the point (4,122) represent?
b.What is the unit rate?
c.What is the cost of buying 10 tickets?
Answers
Answer:
a) The point (4, 122) represents that the cost of 4 tickets is $122
b) The unit rate is 30.5 dollars per ticket
c) The cost of buying 10 tickets is $305
Step-by-step explanation:
Let us solve the question
From the given graph
∵ The x-axis represents the number of tickets
∵ The y-axis represents the cost of tickets in dollars
∴ The line represents the relationship between the number of tickets
and their cost
a)
∵ The point (4, 122) lies on the line
∴ x = the number of tickets
∴ y = their cost
∵ x = 4 and y = 122
∴ The cost of the 4 tickets is 122 dollars
∴ The point (4, 122) represents that the cost of 4 tickets is $122
b)
∵ The unit rate is the slope of the line
∵ The slope of the line = Δy/Δx, where
Δy = y2 - y1 Δx = x2 - x1∵ The line passes through points (0, 0) and (2, 61)
∴ x1 = 0 and x2 = 2
∴ y1 = 0 and y2 = 61
→ Substitute them in the rule of the slope above
∴ The slope of the line = [tex]\frac{61-0}{2-0}[/tex] = [tex]\frac{61}{2}[/tex] = 30.5
∴ The unit rate is 30.5 dollars per ticket
c)
∵ The linear equation is y = m x + b, where
m is the slope of the line b is the y-intercept (value y at x = 0)∵ m = 30.5 ⇒ the slope of the lone
∵ b = 0 ⇒ The line passes through the origin point (0, 0)
∴ The equation of the line is y = 30.5x
∵ x = 10 ⇒ number of tickets
→ Substitute x by 10 in the equation to find the cost of 10 tickets
∴ y = 30.5(10)
∴ y = 305
∴ The cost of buying 10 tickets is $305

plz explain your answer
Answers
Answer:
Juan
Step-by-step explanation:
The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:
For Ana
Ana read 15% of her 46-page book.
= 15% × 46 pages
= 6.9 pages
For Hillary
Hillary read 11% of her 72-page book.
= 11% × 72 pages
= 7.92 pages
For Roger
Roger read 12% of his 68-page book.
= 12% × 68 pages
= 8.16 pages
For Juan
Juan read 14% of his 69-page book.
= 14% × 69 pages
= 9.66 pages
The person who can read greatest number of pages in a day also means the person who read the highest number of pages in a day.
From the calculation above, that person in JUAN because she can read 9.66 pages of her book in one day.

If
f(x) = x?+ 2x- 4
and
g(x) - 3x+ 1
Find
g(f(3) = [? }+x +
Answers
Step-by-step explanation:
(g o f)(x)
= g(x² + 2x - 4)
= 3(x² + 2x - 4) + 1
= 3x² + 6x - 11.
G(x) = 3x + 1
Find g(f(x))
- when it says g(f(x)), this means that you plug in the equation or value you were given for f(x) into EVERY x-value seen in the g(x) equation.
-in the g(x) equation (3x + 1) you were given ONE x-value.
So...
-you replace the x with the f(x) equation which is, x^2 + 2x - 4 (as shown below)
g(f(x)) = 3(x^2 + 2x - 4) + 1
• then distribute the 3 on the outside of the brackets with each number inside the bracket
= 3x^2 + 6x - 12 + 1
• add all the like terms up and you should get your final equation
= 3x^2 + 6x - 11 OR 3x^2 + 6x + (-11)
