Answer:
[tex]y=\frac{3}{5} x-3[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx+ b
m = slope
b = y-intercept
Rearrange the equation:
[tex]-20y=-12x+60[/tex]
Divide each side by -20:
[tex]\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}[/tex]
[tex]y=\frac{3}{5} x-3[/tex]
[tex]y=\frac{3}{5} x-3[/tex] is your simplified, slope-intercept form equation.

Answer:
♧ = 7♢ = 6♡ = 5♤ = 2Step-by-step explanation:
The second equation tells you ...
♧ = 21/3 = 7
The third equation tells you ...
♢ = 20 -2(7) = 6
Then the first equation tells you ...
♤ = 15 -7 -6 = 2
Finally, the last equation tells you ...
♡ = 13 -6 -2 = 5
Answer
Club = 7
Diamond = 6
Spade = 2
Heart = 5
Step-by-step explanation
Here it shows that 1 club + 1 diamond + 1 spade is equal to 15. Ok, let's get back to that one later.
In the next hint it shows that 3 clubs equals 21. So, in order to get the value of the club, divide 21 by 3, and you'll get 7. This means that 7 is the value of the club.
Now on to the third hint. Here it shows that 1 diamond plus 2 clubs are equal to 20. We already got the value of the club, which is 7, so add 7+7 and you'll get 14. Then, subtract 14 from 20 and you'll get the value of the diamond, which is 6.
Finally, the fourth hint. Here it shows that 1 diamond + 1 heart + 1 spade = 13. So, inorder to get the value of the heart, add the value of the diamond and the spade, which sums up to 8. Then subtract 8 from 13 and you'll get the value of the heart, which is 5.

Answer:
£59.25
Step-by-step explanation:
It appears you can measure the height of the trapezoid [trapezium :-) ??]. If you can't, you can use the Pythagorean Theorem (image attached). Draw a line from the upper right-hand corner down to the baseline--the 20m side. You'll form a right triangle with one leg h , hypotenuse 17m and the other leg 8m (the difference between 20m and 12m).
(leg)^2 + (leg)^2 = (hypotenuse)^2
h^2 + 8^2 = 17^2
h^2 + 64 = 289
h^2 = 225
h = 15m
The area of the trapezium is [tex]A=\frac{1}{2}h\left(b_1+b_2\right)[/tex] where the b's are the lengths of the two bases (upper and lower sides).
[tex]A=\frac{1}{2}(15)(12+20)=\frac{1}{2}(480) = 240[/tex] m^2
One can of weedkiller covers 100 m^2 of area. You'll need 3 cans (2 cans isn't enough, and you can't buy a fraction of a can). Tricky question!
Three cans will cost 3 x 19.75 pounds = £59.25

The length of a
rectangle is represented by
4a + 3b, and its width is
represented by 7a – 2b. Write
a polynomial for the perimeter
of the rectangle.
Solution:
Given:
Length of rectangle = 4a + 3bWidth of rectangle = 7a - 2bPerimeter of rectangle = 2W + 2LLet's simplify the perimeter of the rectangle by using the expression for the perimeter.
=> 2W + 2L=> 2(7a - 2b) + 2(4a + 3b)=> 14a - 4b + 8a + 6b=> 22a + 2bHence, the polynomial that represents the perimeter of the rectangle is 22a + 2b.
What fraction is equal to 75% of 1/3
Answer:
1/4
Step-by-step explanation:
1.) Take 75% and convert it to a decimal, which is 0.75
2.) Then multiply 1/3 by 0.75
3.) Your answer is 0.25, and when 0.25 is converted to a fraction it is 1/4.
75% of 1/3 can be expressed as the fraction 1/4 by convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction
To find the fraction that is equal to a given percentage of another fraction, follow these steps:
Step 1: Convert the percentage to a decimal by dividing it by 100. In this case, 75% is equivalent to 0.75.
Step 2: Multiply the decimal by the original fraction. In this case, 0.75 * 1/3 = 0.25/1.
Step 3: Simplify the resulting fraction, if possible. In this case, the fraction 0.25/1 can be simplified to 1/4.
Therefore, 75% of 1/3 is equal to the fraction 1/4.
To find the fraction that represents a given percentage of another fraction, convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction if necessary. In this case, 75% of 1/3 is equal to the fraction 1/4.

Which formula should be used to calculate the variance?.
Answer:
C is the formula you should use and the rest of the answers are below
Step-by-step explanation:
Hence, the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.
We have Variance.
We have to specify the formula of variance.
What is Variance?Variance is a measure of dispersion that takes into account the spread of all data points in a data set.
According to the question, the following formulae for variance are used according to the need.
For a Complete Population divide by the size n -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex]
For a Sample Population divide by the sample size minus 1
[tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex]
Hence, the the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.

Given:
Two pairs of parallel lines j and k, and r and s traverse each other.
d° = f° {opposite angles}
a° + d° = 180°
This is an incorrect statement.
a° = c° {Corresponding angles}
b° + e° = 180° (Sum of linear pair)
