what’s the answer for
this
Answers
Answer:
4/3
Step-by-step explanation:
The slope equals the rise/run
Start at the first point on the graph. Then count how many times you went up till you are parallel with the second point. That will be the rise, which in this case is 4.
Then from your new point count how many times you went right, and that will be your run. In this case it is 3.
Put the rise an top, and the run on bottom, and you get the slope 4/3!

You have at most $75 to spend on books and music. You want to spend less than $20 on music and no more than $60 on books. Which system represents the situation?
Answers
Answer:
$20>$75>$60
Step-by-step explanation:
hope it helps
The system of inequalities that represent the situation are -
x < 20
y ≤ 60
x + y ≤ 75
We have $75 to spend on books and music and we want to spend less than $20 on music and no more than $60 on books.
We have to determine which system represents the situation.
You have $50 to spend on chocolates and toffees. You want to spend more than $20 on toffees and less than $15 on chocolates. How will you find the possible solutions under such constraints ?Assume the cost spend on toffees is $x and that on chocolates is $y. Then-
x > 20
y < 15
x + y ≤ 50
Solve them graphically and you will find the possible solution set.
According to the question, we have -
Amount available to spend = $75
For music → amount < $20
For books → amount ≤ 60
Assume the cost spend on music is $x and that on books is $y.
Then -
x < 20
y ≤ 60
x + y ≤ 75
Check the graph attached for solution region. The points inside the triangle formed (marked by red thick boundary) represents the points which satisfy the above conditions.

the sum of three number is 202, the second is three more than the first number, the third number is three times the second number. what are the three numbers ?
Answers
Answer:
x = 38
y = 41
z = 123
Step-by-step explanation:
x + y + z = =202
y = x + 3
z = 3y = 3(x + 3) = 3x + 9
x + y + z = x + x + 3 + 3x + 9 = 5x + 12 = 202
5x + 12 = 202
5x = 190
x = 38
y = x + 3 = 41
z = 3y = 123

(v) Are 2, 3, 5, 7 and 11 factors of 4620?
Answers
Answer:
(i) Yes. If you divide it, it gives 13.
(iii) 3 is a factor of 1647 but 5 isn't. If you divide it with 3 first, it gives 549. But if you divide it with 5, it gives 329.4
(v) 2, 3, 5, 7 and 11 are factors of 4620. If you divide it with 2, it gives 2310. If you divide it with 3, it gives 1540. If you divide it with 5, it gives 924. If you divide it with 7, it gives 660. If you divide it with 11, it gives 420.
Step-by-step explanation:
Extra explanation on what a factor is, I don't know how to explain it but here are some examples:

17 cm

15 cm-
Area - Triangles
Overview
Answers
Answer:
There are 3 possible answers because you didn't state which value was base or height.
Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*8)
A = 1/2(120)
A = 60
Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)
A = 1/2(b*h)
A = 1/2(17*8)
A = 1/2(136)
A = 68
Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*17)
A = 1/2(255)
A = 127.5

[tex]\boxed{\textsf{ The first negative term of the sequence is \textbf{-4} .}}[/tex]
Step-by-step explanation:
A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-
[tex]\sf\implies Sequence = 31 , 26 , 21 , 16 ..... [/tex]
Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .
Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .
And that term will be , 16 - 15 = 1 .
Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.
[tex]\sf \implies 1st \ negative \ term = 1 -5 =\pink{-4} . [/tex]
