☄ Question : Subtract the following using horizontal method :
i. 2x from -5x-5a from -18a✎ Step - by - step Explanation :
2x from -5xIn horizontal method , terms are arranged in same row and put sign for subtraction and remove the brackets and then simplify.
[tex] \longrightarrow{ \sf{ - 5x - (2x)}}[/tex]
[tex] \longrightarrow{ \sf{ - 5x - 2x}}[/tex]
Like terms can be added or subtracted. Only coefficients of like terms can be added or subtracted.
[tex] \longrightarrow{ \boxed{\sf{ - 7x}}}[/tex]
Likewise , Let's do next too:
-5a from 18 a[tex] \dashrightarrow{ \sf{ 18a - ( - 5a)}}[/tex]
Remember : [tex] \sf{( - ) \times ( - ) = ( + )}[/tex]
[tex] \dashrightarrow{ \sf{ 18a + 5a}}[/tex]
[tex] \dashrightarrow{ \boxed{ \sf{ 23a}}}[/tex]
And we're done!
Hope I helped!
Have a wonderful time ツ

Find the slope and the y-intercept of the graph of the linear equation.
y+7=5/4x
The slope is
and the y-intercept is
Answer:
your slope would be 5/4
Step-by-step explanation:
your x will always be your slope. when you rewrite the equation it would be
y=5/4x-7
so from -7 you would go up 5 and over 4.
Again your x value will always be your slope.

70 / 12
Answer:
6.3
Step-by-step explanation:
You want to add 1, 5, and 70 up. Then you would get 76. Next you want to divide 76 into 12. And there you go, 6.3 is the answer

Prove that
sec A cosec A - cotA= tan A.
Can someone’s please help me with this one.. I’ll give brainliest
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
secx = [tex]\frac{1}{cosx}[/tex] , cosecx = [tex]\frac{1}{sinx}[/tex]
cotx = [tex]\frac{cosx}{sinx}[/tex] , tanx = [tex]\frac{sinx}{cosx}[/tex]
Consider the left side
secA cosecA - cotA
= [tex]\frac{1}{cosA}[/tex] × [tex]\frac{1}{sinA}[/tex] - [tex]\frac{cosA}{sinA}[/tex]
= [tex]\frac{1}{cosAsinA}[/tex] - [tex]\frac{cosA}{sinA}[/tex]
= [tex]\frac{1-cos^2A}{cosAsinA}[/tex]
= [tex]\frac{sin^2A}{cosAsinA}[/tex] ( cancel sinA on numerator/ denominator )
= [tex]\frac{sinA}{cosA}[/tex]
= tanA = right side ⇒ proven

A water slide starts at (0,144) and ends at (12,0) what is the slope of the slide
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{144-0}{0-12} = \frac{144}{-12} = -12[/tex]

The difference between the C.I. and S.I. calculated annually on ₹ 625 at 10 % per
annum for 1 year is:
Answer:
R0
Step-by-step explanation:
Given the following data;
Principal, P = R625
Time, t = 1 year
Rate, r = 10% = 10/100 = 0.1
To find compound interest;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Substituting into the equation, we have;
[tex] A = 625(1 + \frac{10}{100})^{1}[/tex]
[tex] A = 625(1 + 0.1)[/tex]
[tex] A = 625(1.1)[/tex]
A = 687.5
Therefore, C.I = A - P
C.I = 687.5 - 625
C.I = 62.5
To find the simple interest;
[tex] S.I = \frac {PRT}{100} [/tex]
[tex] S.I = \frac {625 *10*1}{100} [/tex]
[tex] S.I = \frac {6250}{100} [/tex]
S.I = 62.5
Now to find the difference;
Difference = C.I - S.I
Difference = 62.5 - 62.5
Difference = R0

A canteen spends money on food and drink in the ratio of 29:3
In total, they spend £6496.
Find how much money they spend on drink.
Answer:
Money spend on drink = £ 609
Step-by-step explanation:
Food : drink = 29 : 3
Money spend on food = 29x
Money spend on drink = 3x
Total money spend = 29x + 3x = 32x
32x = £6496
x = 6496/32
x = £ 203
Money spend on drink = 3x = 3 * 203 = £ 609

Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence.
d = 12 - 8 = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 4 , then
[tex]a_{n}[/tex] = 8 + 4(n - 1) = 8 + 4n - 4 = 4n + 4
