Slope: (y2-y1)/(x2-x1)
(7-5)/(12-4) = 2/8 = 1/4
The slope is 1/4
The answer is d. square root because the square root multiples by the number itself to get the number.
Given : x + y = 99 ------------ [1]
Given : x² - y² = 99
We know that : (x² - y²) = (x + y)(x - y)
⇒ (x + y)(x - y) = 99
⇒ 99(x - y) = 99
⇒ x - y = 1 ------------- [2]
Adding Equation [1] and [2], we get :
⇒ (x + y) + (x - y) = 99 + 1
⇒ 2x = 100
⇒ x = 50
Substituting x = 50 in Equation [1], we get :
⇒ 50 + y = 99
⇒ y = 99 - 50
⇒ y = 49
So, The Ordered pair (x , y) = (50 , 49)
1) 3n+1=16-2n
- add 2n to both sides
- you should now be left with 5n+1=16
(remember the 2n gets canceled out)
- subtract 1 from both sides
- you should now be left with 5n=15
- now you divide by 5 to get n by itself
- 15 divided by 5 is 3
- n=3
2) substitute n with 3 in to the original equation
- so 3n+1=16-2n now becomes 3(5)+1=16-2(3)
- you should get 10 for both so 10=10
3) according to the segment addition postualte , XR + YR = XY.
- add 10+10 which stands for the lengths of XR and YR
Answer - XY = 20
21p + 10g = 770 ...multiply by -2
7p + 20g = 840
-------------------
-42p - 2g = - 1540 (result of multiplying by -2)
7p + 20g = 840
------------------
-35p = - 700
p = -700/-35
p = 20 <=== pink sponsorships cost $ 20 a piece
