Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Express your answer as a fraction in simplest form.
The solution is
Note: The expression you have written sounds a little unclear, but I am assuming your expression is (27)-2-2/3.
So, I am solving the question based on assuming the expression as (27)-2-2/3, which would still clear your concept.
Answer:
The expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
simplifying the expression in the simplest form
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
[tex]=25-\frac{2}{3}[/tex]
[tex]=\frac{25\cdot \:3-2}{3}[/tex]
[tex]=\frac{73}{3}[/tex]
Thus, the expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]

Question 4 of 10
Which of the following is equal to divide 9•4
Answer:
36 ÷ 9= 4
Step-by-step explanation:
9 x 4= 36
The division equation for this is 36 ÷ 9= 4
The product of the expression 9 and 4 is 36.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Give that we have to multiply 9 with 4.
This means that 9 has to be added repeatedly up to 4 times or 4 has to be added repeatedly up to 9 times.
In both cases, the product must be the same.
9 multiplied by 4 = 9 + 9 + 9 + 9
Which is also equal to,
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4
= 36
Hence the product is 36.

Answer:
see the attachment
Step-by-step explanation:
1. Lay out points A and B so they are 5.5 cm apart.
2. Set the compass to 5 cm and draw arcs that intersect above and below segment AB. Label the intersection points Y and Z.
3. Draw segment YZ as a perpendicular bisector of AB.
4. Label the intersection of YZ and AB point E.
5. Using E as the center and AE as the radius, draw an arc that intersects segment YZ at F.
6. Draw segment AD through F. D will lie on the circle of radius 5 cm centered at A. This segment makes 45° angle DAB.
7. Draw an arc of radius 4 cm centered at D through the vicinity of point C.
8. Draw an arc of radius 3.5 cm centered at B through the vicinity of C. The intersection point with the arc of step 7 is point C.
9. Draw quadrilateral ABCD meeting the given requirements.

Answer:
radius: 4.2 cm
circumference: 26.376 cm^2
area: 55.3896 cm^2
Step-by-step explanation:
radius is half the diameter so 8.4/2 = 4.2
circumference: C = (2)(pi)(r) ---> (2)(3.14)(4.2) --> 26.376
area: (pi)(r ^2) --> (3.14)(4.2^2) --> 55.3896

HELP ME PLEASE DON’T STEEL MY POINT
Lin’s uncle is opening a bakery. On the bakery’s grand opening day, he plans to give away prizes to the first 50 customers that enter the shop. Every fifth customer will get a free bagel. Every ninth customer will get a free blueberry muffin. Every 12th customer will get a free slice of carrot cake.
Diego is waiting in line and is the 23rd customer. He thinks that he should get farther back in line in order to get a prize. Is he right? If so, how far back should he go to get at least one prize? Explain your reasoning.
Answer:
Diego is correct, he should move back one space.
Step-by-step explanation:
If every 5th customer gets a free bagel then you should be able to count up by 5s to figure out which people get the bagel. (5, 10, 15, etc.)
It would be the same for 9 and 12 (9, 18, 27, etc.) (12, 24, 36, etc.).
However, 23 is not divisible by 5, 9, or 12 (I moved on to division because it's the fast way to check)
But if you look at the multiples of 12 then you'll see that the 24th person would get a prize.
So, Diego should go back one space in order to get a prize because 23 is not a multiple of 5, 9, or 12. However, 24 is a multiple of 12.
Hope this helps and makes sense.

Find the slope-intercept equation of the line.
Need the equation
Plz help not jus the answer
Answer:
y=-3x+5
Step-by-step explanation:
Answer is Y=-3x+5
Answer:
y = -1/2x + 5
Step-by-step explanation:
First, we need to find the slope. Slope is nothing but the height of the triangle over the length of the triangle. Since the height is 5 is the length is 10, the slope should be 5/10. But, since the line is slanting downwards, the slope is negative. So it is -5/10, or -1/2 when simplified. Next, we need to find the y intercept. Y intercept is nothing but where the line crosses the y axis, so the y intercept should be 5. The slope intercept is y = mx+b, where m is the slope and y intercept is b, so our equation should be y = -1/2x + 5.
The reason that we are not counting the individual squares is because they already labeled the graph. So, we have to count accordingly.

Given: AC = 40. Fill in the reason that justifies each step.
(4x+4)+(5x)=(40)
9x + 4 = 40
9x = 36
x = 4
Will give brainliest
Answer:
True, every step that was done is correct.
Step-by-step explanation:
Since that whole line of AC equals 40, and that (4x+4)+(5x) also equals the whole line, you can just do it this way: (4x+4)+(5x)=40 Solve for x and x will equal 4. I even used an algebra calculator to solve for x and the calculator indeed said that x=4 (the image is shown below on the calculator I used to solve for x).
Hope this helped! :)
