Answer:
y = -5/3x+8
Step-by-step explanation:
Equation: y=mx+b
You find the slope (m) by calculating the distance between the two points. For the y axis, 3 is -5 away from 8. For the x axis, 3 is 3 away from 0. You then devide y by x, which gives you -5/3.
To get the y intercept (b), you just look at the graph, where it's at 8.
God luck!
Answer:
y = -5/3x + 8
Step-by-step explanation:
Points on the graph: (0, 8) and (3, 3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3-8)/(3-0)
m= (-5)/3
m= -5/3
Slope-intercept:
y - y1 = m(x - x1)
y - 8 = -5/3(x - 0)
y - 8 = -5/3x
y = -5/3x + 8

Nadia has £5 to buy pencils and rulers. Pencils are 8p each. Rulers are 30p each. She says “I will buy 15 pencils. Then I will buy as many rulers as possible. With my change, I will buy more pencils.” How many pencils and how many rulers does she buy?
Answers
Answer:
Total pencils: 17
Total rulers: 15
Step-by-step explanation:
"I will buy 15 pencils."
15 * 8p = £1.20
15 pencils
"Then I will buy as many rulers as possible."
£5 - £1.20 = £3.80
£3.80/30p = 12 remainder 20p
12 rulers
"With my change, I will buy more pencils.”
20p/8p = 2 remainder 4 p
2 pencils
Total pencils: 17

If a letter is randomly chosen, what is the probability of choosing the letter A?
Answers
Answer:
it depends on how many letters there are to choose from.
Answer:
if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%
Step-by-step explanation:
There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!
Or if you want to be really specific, 1/26 as a percent is 3.8462%.

How to solve for shaded area
Answers
Answer:
(a) 12.96 ft²
(b) 21.5 in²
Step-by-step explanation:
(a) For the first diagram
Area of the shaded region (A) = Area of Tripezium- area of circle
A = [1/2(a+b)h]-[πr²]............... Equation 1
Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.
From the diagram,
Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.
Constant: π = 3.14
Substitute these values into equation 1
A = [12(15+6)/2]-(3.14×6²)
A = 126-113.04
A = 12.96 ft²
(b) For the second diagram,
Area of the shaded region (A') = Area of square- area of circle
A' = (L²)-(πr²)............. Equation 2
Where L = lenght of one side of the square, r = radius of the circle
From the diagram,
Given: L = 2r = (2×5) = 10 in, r = 5 in
Substitute these values into equation 2
A' = (10²)-(3.14×5²)
A' = 100-78.5
A = 21.5 in²

help me pleasee !
Answers
Answer:
y = (x + 1)(x - 0.586) ( x - 3.414)
Step-by-step explanation:
I sure wouldn't recommend doing this by trial and error.
I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.
y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2
are the listed roots.
The square root is
y = (x + 1)(x - 0.586) ( x - 3.414)
Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2
you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Calculate the length of side x.
Answers
Answer:
30cm
Step-by-step explanation:
Because of the polygon similarity postulate (PSP) 8/12=20/x
8/12=20/x
20/(8/12)=x
20*12/8=x
x=30 cm
The length of side x is 30 cm when the shapes below are mathematically similar.
To calculate the length of side x, we can use the concept of similarity between the shapes. When two shapes are mathematically similar, their corresponding sides are proportional.
8 cm corresponds to 20 cm
12 cm corresponds to x (unknown)
Using the concept of proportionality, we can set up the following equation:
(8 cm) / (20 cm) = (12 cm) / (x)
To find x, we can solve this equation:
Cross-multiplying:
8 cm * x = 20 cm * 12 cm
Simplifying:
8x = 240 cm²
Dividing both sides by 8 to isolate x:
x = 240 cm²/ 8
x = 30 cm
Therefore, the length of side x is 30 cm.
