Answer:
y=-3x+6
Step-by-step explanation:
In the equation for a line y=mx+b, m is the slope, so you can get y=-3x+b.
You are given (1,3), so you can plug in 1 for x and 3 for y. You should get 3=-3(1)+b, so b=6. Plugging in b to y=-3x+b, you should get y=-3x+6.

The area of a square garden is 49 yd2. How long is each side of the garden? in yd.
please this is important
Answer:
Yo, check this out, S=a×a=a², the formula to find the area of a square.
Step-by-step explanation:
S=49 yd²
S=a×a=a²
a²=49===> √a²=√49 yd²===> |a|=7 yd===> a=7, –7
but be aware that we ain't got no squares with a negative length, so the answer is
7 yd

Find the area of this figure. Round your
answer to the nearest hundredth.
Use 3.14 to approximate a.
A = [?] m2
Notice that only half of the circle is included in the figure!
Answer:
51.63m^3
Step-by-step explanation:
The figure is made up of a rectangle, triangle and a semi circle
Area of the figure = Area of triangle + rectangle + semicircle
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 3 * 5
Area of the triangle = 15/2
Area of the triangle = 7.5m^3
Area of the rectangle = Length * Width
Area of the rectangle = 6 * 5
Area of the rectangle = 30m^2
Area of the semicircle = πr²/2
Area of the semicircle = π(3)²/2
Area of the semicircle = 3.14(9)/2
Area of the semicircle = 3.14 * 4.5
Area of the semicircle = 14.13m^2
The area = 30 + 14.13+7.5
Area of the figure = 51.63m^3

51.63m²

Christopher is 20 years younger than Ishaan. Ishaan and Christopher first met two years ago. Fourteen years ago, Ishaan was 3 times as old as Christopher.
How old is Christopher now?
Answer: Yw :^
Step-by-step explanation: Present: Ishaan = Christopher + 20 - Equation 1
1 years back: Ishaan-14 = 3(Christopher-14) - Equation 2
Solve above equations:
I = 3c-42+14
I = 3c-24
I = c+20
2c-44 = 0
Christopher = 22 then from Equation 1
Ishaan = 22 + 20 = 42

3x+2y=10 y=3x-4
x= y=
Answer:
x=2; y=2
Step-by-step explanation:
3x+2y=10
y=3x-4
We can substitute y from the first equation with the second equation:
3x+2(3x-4)=10
3x+6x-8=10
9x=18
x=2
Now plug this in to any of the equations (i used second equation):
y=3(2)-4
y=6-4
y=2
Check your answers:
y=3x-4
2=3(2)-4
2=6-4
2=2

Step-by-step explanation:
solve for the area of the triangle and the rectangle separately, then add the values together.
Jamal has some counters in a bag.
36% of the counters are red
the rest of the counters are yellow
Jamal puts 50 blue counters into the bag.
Now 25% of the counters in the bag are blue.
Work out the number of yellow counters in the bag.
(3 marks)
The number of yellow counters in the bag Jamal has got for this case is obtained being 96
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given that:
The bag initially had 36% of red counters and rest of the counters being yellow in color.Later was added 50 blue counters.The number of blue counter in the bag is 25% of all the counters in the bag.Let the initial number of counters in the bag be 'x'
Then, 36% of x is:
[tex]\text{Number of red counters} = \dfrac{x}{100} \times 36 = 0.36 \times x[/tex]
Rest of them are yellow, so we get:
[tex]\text{Number of yellow counters} = x - \dfrac{x}{100} \times 36 = x(1-0.36) = 0.64 \times x[/tex]
Now, adding 50 blue counters make:
Total count of counters in bag = [tex]x + 50[/tex]
25% of this count is blue, and we know its 50. Thus, we get:
25% of (x+50) = 50
or
[tex]\dfrac{x+50}{100} \times 25 =50\\\\x+50 = 4 \times 50\\\\x = 200-50 = 150[/tex]
Thus, there were 150 coutners in the bag, initially.
The number of yellow counters is:
[tex]\text{Number of yellow counters} = 0.64 \times x = 0.64 \times 150 = 96[/tex]
Thus, the number of yellow counters in the bag Jamal has got for this case is obtained being 96
