Answer:
x=3y
Step-by-step explanation:
ATQ
(x+y):(x-y)=2
or, x+y=2x-2y (crossmultiply)
or, 0= 2x-x-2y-y
or, x- 3y=0
or, x=3y is required equation
Answer:
-5
Step-by-step explanation:
-5x-12= 13 add 12 to both sides
-5x-12 + 12= 13 + 12 ➡ -5x = 25 divide both sides by 5
-5x ÷ 5 = 25 ÷ 5 ➡ -x = 5 and x = -5
Answer:
20.7%
Step-by-step explanation:
Amount of stock increased in Company A = 20% of 1790
= 0.20 * 1790 = $ 358
Investor's stock in company A this year = 1790 + 358 = $ 2148
Amount of stock increased in Company B = 22% of 1000
= 0.22 * 1000= $ 220
Investor's stock in company B this year = 1000 + 220 = $ 1220
Total amount in investor's stock account = 2148 + 1220 = $ 3368
Increased amount = 3368 - 2790 = $ 578
Increase percentage = 
= 20.71
= 20.7%
From secant theorem, 16^2 = 8(12 + y); where y is the missing length of the secant.
256 = 8(12 + y)
12 + y = 32
y = 32 - 12 = 20
From chord theorem, 4x = 4(20)
x = 20
Answer:
1) 1
2) -2/5
3) 2
4) 5/3
5) 0
Step-by-step explanation:
So basically you take the y's (x,y) and you subtract them. If you were to subtract them from left to right, you subtract the x's (x,y) left to right as well.
If you decide to subtract from right to left for y's you do the same for x's.
Then after you have a fraction you will either divide if able to or you keep it as a fraction.
For example number 1 is (0,3) and (1,4)... You will take the y's which is 3 and 4. You will then subtract left to right or right to left. Doing so will get you to 1 for the y. For the x's you do the same. The x's are 1 and 0. Which will be subtracted the same direction as the y's. the ending fraction will be 1/1 ... The top will always be the y subtraction answer and the bottom will always be the x subtraction answer.
