These tables of ordered pairs represent some points on the graphs of lines s and t.
Which system of equations is represented by lines s and t?
5x−2y=−157x+4y=20
3x+5y=−185x−9y=25
x+4y=−89x−y=21
2x−y=−142x+y=6
Answers
Answer:
Step-by-step explanation:
Line s
slope m = Δy / Δx = (22 - 4) / (4 - (-5)) = 18/9 = 2
y = mx + b
22 = 2(4) + b
b = 14
y = 2x + 14
which can be rearranged to
2x - y = -14
Line t
slope = ( -4 - 14) / (5 - (-4)) = -18/9 = -2
-4 = (-2)(5) + b
b = 6
y = -2x + 6
2x + y = 6
2x − y = −14 2x + y = 6

Answer:
m∠O = 41°
Step-by-step explanation:
∠NOM=∠NMO=(4y-15)° (base angles of isos triangle)
7y+2(4y-15)=180 (angle sum of triangle)
7y+8y-30=180
15y-30=180
15y=180+30
=210
y=210÷15
=14
Hence, m∠O = (4y-15)°
= [4(14)-15]°
= (56-15)°
= 41°
Is this statement true or false? The expression 4x (x2 + 4x + 3) is a polynomial. O True O False
Answers
Answer:
Step-by-step explanation:
If you remove the brackets you get
4x^2*x^2 + 4x*4x + 3*4x
4x^4 + 16x^2 + 12x
That definitely is a polynomial
In its factored form, one of the factors is a polynomial so the answer is true.

amara needs to create a special tasting menu at her restaurant. She needs to select 4 dishes from 7 available dishes and put them in a tasty sequence. How many unique ways are there to arrange 4 of the 7 dishes?
Answers
By taking in mind the number of combinations of 4 out of the 7 dishes, and the possible orders of these 4 dishes, we will find that there are 840 unique ways to arrange 4 of the 7 dishes.
We know that if we have a set of N elements, the total number of different combinations of K elements (K ≤ N) out of the N elements is given by:
[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]
In this particular case, we have:
N = number of available dishes = 7K = number that we need to select = 4Then the number of different combinations is given by:
[tex]C(7, 4) = \frac{7!}{(7 - 4)!*4!} = \frac{7*6*5}{3*2} = 35[/tex]
Now we have 4 dishes selected, but we also need to order them.
For the first dish, there are 4 options.For the second, there are 3 options (as one was already selected).For the third, there are 2 options.For the last one there is only one option.The number of different arrangements of the dishes is given by the product between the numbers of options above, this gives:
4*3*2*1 = 24
Then the total number of unique ways of arranging 4 of the 7 dishes is:
C = 24*35 = 840
Where we take in mind the possible number of combinations of 4 out of the 7 dishes, and the possible orders of these 4 dishes.

Gina wants to duplicate this circle graph. Which of the following is closest to the measure of the central angle of the
"walking" sector?
Answers
Using proportions, it is found that the central angle of the walking sector is of 36º.
This question can be solved by proportions, using a rule of three.The angle corresponding to 100% = 1 is of 360º, while we want to find the angle corresponding to the walking sector, which is of 10% of the circle.Hence, the rule of three is:
1 - 360º
0.1 - x
Applying cross multiplication:
[tex]x = 360(0.1) = 36[/tex]
The central angle of the walking sector is of 36º.

(b) What output does the rule give when the input is (0, -5)? Show your work.
(c) Is the rule a function? Explain why it is or why it is not.
Answers
(6, -2)
(b) 0 + 8, -5 - 3
(8, -8)
(c) Yes, the rule is a function because x will never overlap with x and y will never overlap with y, when graphed it passes the vertical line test.
Answer:
I might be getting somthign comfised but here is what I derived from it.
Step-by-step explanation:
Marcus uses a rule of (x+8, y-3). What will be the output if the input is (-2,1) and (0,-5).
If it is going off of the math functions then the outputs would be simple math -
(6, -2) -2+8 and -3+1; (8, -8) 0+8 and -5-3 [if im doing the correct functions].
The X and Y is what gets me when trying to answer if it is a function or not, I would say it is because the x and y values are given and they are their values are substituted, the actual function is adding the 8 to the X and subtracting the 3 from the Y.

Answers
Answer: 13 3/4
Step-by-step explanation:
The gopher’s new elevation relative to the surface of the ground will be
[tex]13 \frac{1}{4}[/tex] inches.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
A gopher is in a hole that is [tex]6 \frac{1}{4}[/tex] in. below the surface of the ground.
And, Then digs [tex]7 \frac{1}{2}[/tex] in. deeper.
Now,
The gopher’s new elevation relative to the surface of the ground will be calculated as;
⇒ [tex]6 \frac{1}{4} + 7 \frac{1}{2}[/tex]
⇒ 25/4 + 15/2
Make denominators same as;
⇒ 25/4 + 30/4
⇒ (25 + 30) / 4
⇒ 55 / 4
⇒ [tex]13 \frac{1}{4}[/tex] inches.
Thus, The gopher’s new elevation relative to the surface of the ground will be [tex]13 \frac{1}{4}[/tex] inches.
