What is the slope of the line through the points (2, 8) and (4, 6)?a) slope = 73
b) slope = -1
c) slope = 1
d) slope = 1/3

Answers

Answer 1
Answer: slope=(y2-y1)/(x2-x1)

(x,y)

we have
(2,8)
(4,6)
x1=2
y1=8
x2=4
y2=6


slope=(6-8)/(4-2)=-2/2=-1


slope=-1
answer is C

Xx is 25% of 104, 7 is 10% of yy, and nn is 80% of yy. yy is what percent of (n+y−x)(n+y−x)?

Answers

x = 0.25×104 =26
y = 7 × 10 = 70
n = 70 × 0.8 = 56

(56+70-26)(56+70-26)
⇒(100)(100) = 100

(70)/(1000) × 100 = 7%

What is three fifths plus two fourths equal

Answers

3/5 +2/4
commonfactor
4,8,12,16,20
5,10,15,20,25

x the first fractiob by 4 and the 2nd by 5 =
12/20+10/20=22/20 =11/10 =1 1/10
3/5 + 2/4=?
first you have to do 3/5 times 4 and that equals 12/20.
next you do 2/4 times five and that equals 10/20.
then you add those and you get 22/20= 1 2/20 and when you simplify 2/20 you get 1/10.
your answer is 1 and 1/10

Solve for a.

5a - 2 = 23
a = ?

Answers

5a - 2 = 23.

First, take 5a - 2 = 23 and add 2 to each side

5a - 2 = 23
     +2    +2
5a = 25

now, divide each side by 5

5a = 25
/5      /5

a = 5

Answer:

a=5
