A straight line passes through 0 and (2, 6)
Circle the equation of the line
[1 mark]
Answer:
y = 3x
Step-by-step explanation:
To find out what the equation is here, divide the y coordinate by the x coordinate of the point given (2, 6). Here divide 6 by 2. That would equal 3. That means that the y coordinate is 3 times as much as the x coordinate. As a result we can make the equation y = 3x out of what we now know.

solve 15-(7x+20)=0.5(6x-14)
Answer:
x= 1/5
Step-by-step explanation:
Remove parentheses.
15−7x−20=0.5(6x−14)
Simplify 15-7x-2015−7x−20 to -7x-5−7x−5.
-7x-5=0.5(6x-14)
−7x−5=0.5(6x−14)
3 Expand.
-7x-5=3x-7
−7x−5=3x−7
4 Add 7x7x to both sides.
-5=3x-7+7x
−5=3x−7+7x
5 Simplify 3x-7+7x3x−7+7x to 10x-710x−7.
-5=10x-7
−5=10x−7
6 Add 77 to both sides.
-5+7=10x
−5+7=10x
7 Simplify -5+7−5+7 to 22.
2=10x
2=10x
Divide both sides by 1010.

Liz buys packets of coloured buttons.
There are 8 red buttons in each packet of red buttons.
There are 6 silver buttons in each packet of silver buttons.
There are 5 gold buttons in each packet of gold buttons.
Liz buys equal numbers of red buttons, silver buttons and gold buttons.
How many packets of each colour of buttons did Liz buy?
Answer:
She buys 120 buttons, if you divide 8 by 120 you get 15, so she buys 15 red bags,20 silver bags,and 24 gold bags.

In ΔMNO, n = 85 inches, o = 10 inches and ∠M=56°. Find the length of m, to the nearest inch.
Answer:
80
Step-by-step explanation:
Delta math math
The length of m in triangle MNO is approximately 80 inches.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.
In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:
⇒ m² = n² + o² - 2 × n × o × cos(∠M)
We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:
⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)
We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:
⇒ m = 79.8397 ≈ 80 inches
Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.

If 420 = 120%, what would 100% equal?
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.

4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)
The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.
How to plot a graph?
A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given that a line y=-2x+7
Now in order to satisfy any point of this function then the value or
coordinate should satisfy the function or line.
So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.
So all options except (C) are satisfying.
Option (C) ⇒
-2(-3) + 7 ≠ 1
Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

Question
Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of
the coins is $1.30. How many nickels and how many dimes are in the jar?
The jar contains
nickels and
dimes.
9514 1404 393
Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.
