Answer:
7/3
Step-by-step explanation:
The slope is found by dividing the difference in the y-coordinates by the difference in the x-coordinates.
Here, the difference in the y-coordinates is: 4 - (-3) = 4 + 3 = 7. The difference in the x-coordinates is: 3 - 0 = 3.
Dividing 7 by 3, we get a slope of 7/3.
Answer:
3.14 inches
Step-by-step explanation:
area of circle = πr²
=> 3.14 x 1 x 1
=> 3.14 inches
Answer:
<em>Solution: x =5</em>
Step-by-step explanation:
<u>Solving Equations</u>
Solve the following equation:
( 10 + 4 ) ( 5x - 22 ) = 3( 4x - 6 )
Operating:
14( 5x - 22 ) = 3( 4x - 6 )
Removing parentheses:
70x - 308 = 12x - 18
Subtracting 12x and adding 308:
70x -12x = 308 - 18
Operating:
58x = 290
Dividing by 58:
x = 290/58
x = 5
Solution: x =5
Answer: x = - 2/3
Step-by-step explanation: coz I juss know
Answer:
x=-2 (the actual solution)
x=-5 (the extraneous solution)
Step-by-step explanation:
First step is to isolate the radical part (the part with the square root).
So we will add 4 on both sides first:
To get rid of square we are going to square both sides:
We are going to expand right hand side (you can use "F.O.I.L":
Subtract x on both sides and subtract 6 on both sides:
Combine like terms:
We will now factor:
(Since 2(5)=10 and 2+5=7)
Set both factors equal to 0:
x+2=0 or x+5=0
Solve first equation by subtracting 2 on both sides to obtain x=-2.
Solve second equation by subtracting 5 on both sides to obtain x=-5.
Now let's check to see if these are both actually indeed solutions to the equation we began with:
for :
is a true equation so is indeed a solution.
for :
is false so is what we call the extraneous solution.
