Answer:
1/2
Step-by-step explanation:
The slope of the points (4,-3) and (3,-1) is -2
The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2
heres how you'd find the initial slope of the points
(4, -3)
-1 +2
(3, -1)
Slope= rise/run= 2/-1= -2
I'm not sure if this is correct,
but, I got:
130cm x 100cm ?
13,000cm ?
ANSWER
The first three expressions will simplify to a rational answer.
EXPLANATION
Let us simplify the expressions then we can see which of them are rational.
A.

We multiply out the roots to get

This simplifies to


This is a rational number hence the answer is rational.
B.


This is also a rational solution.
C.


This one too is a rational solution.
D.


This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.
Answer:
20
Step-by-step explanation:
4(2x - 31)=36
4×2x-4×31=36
8x-124=36
8x=36+124
8x=160
x=160/8
x=20
Answer: 20
<u>Step-by-step explanation:</u>
12 is 60% of what number
12 = 0.60 * n
20 = n
