this equation -r + 6 + 8r - 14
Answer:
7r-8
Step-by-step explanation:
yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14
Firstly we will solve -1r +8r
+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r
Now we move on to +6-14
this is just simple addition and subtraction
what is 14-6 it is -8
-14 overpower 6 so we use its sign
Lastly we put it all together and get
7r - 6

4 < x < 9 x is an interger, write down all the possible values of x
Answer:
The possibel values of x is 5, 6, 7, 8.
Step-by-step explanation:
Integer is a positive or negative whole number.
In this case, x must be positive and it have to be greater than 4 but smaller than 9 so the possible values will be 5, 6, 7 and 8.
It says [tex]x[/tex] is greater than [tex]4[/tex] and it is less than [tex]9[/tex]
The first value which is greater than [tex]4[/tex] is [tex]5[/tex] and the value which is less than [tex]9[/tex] is [tex]8[/tex]. So the answer would be all integers from [tex]5[/tex] to [tex]8[/tex] (inclusive)
[tex]5, 6, 7, 8[/tex] would be the answer! :D

Two similar figures have a scale factor of 4/3.
If one side of the smaller figure is 12. determine size of the side of the
corresponding side in the larger figure.
9
16
40/3
32/3
Answer:
This is the concept of scale factors; The length of the larger figure will be calculated as follows;
linear scale factor=[length of larger figure]/[length of smaller figure]
plugging the values in the above formula we get:
let the length of the larger figure be x;
thus;
x/12=4/3
multiplying both sides by 12 to solve for x we get:
12*x/12=4/3x12
x=16
thus the length of the larger figure is x=16
Answer:16
Step-by-step explanation:
12 times 4/3 is 4^2 or 16

a common multiple of 6 and 8,
What number is a common multiple of 6 and 8?
Answer:
6, 12, 18, 24, 30, 36, etc.
Answer:
24
Step-by-step explanation:
Really any number that has a factor with both 6 and 8 would work, but I'm assuming you need the lowest common multiple, which would be 24.
book is 6 inches wide and 9 inches tall. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. A publisher wants to use a scale factor of 1.5 to enlarge a book. What will the area of the front of the book be after the book is enlarged? 54 in2 81 in2 121.5 in2 78.75 in2
Answer:
6x1.5=9
9x1.5=13.5
9x13.5=121.5
Step-by-step explanation:
Answer: 121.5 in²
Step-by-step explanation: If you multiply the width (6 in.) by 1.5 to scale is up you get 9 in. and if you do the same with the length (9 in.) you get 13.5 in. ... You can then calculate the area.

12:4, 8:4
12/3, 8/2, so divide by three and divide by 2, so 3*2 and 3*3 gives us 9 marshmallows and 6 graham crackers
which point is located at (-5,5)
Answer: Point D is at (-5,2) as the first coordinate is on the "X" axis, and the second coordinate is on the "Y" axis. You would move down the x axis first going 5 to the left, as that would be negative. Then two up as that is positive on the y axis! Hope this Helps!
Step-by-step explanation:
PLEASEEE HELP ! I WOULD APPRECIATE IT VERY MUCH :)
hi!
so the original equation is (x^2 -121) / x+ 11.
Those two equations look similar...
well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).
So if we factor that out, we get:
( (x + 11) * (x-11) )/ (x + 11)
we can cancel the x+11 on the top and the x+11 on the bottom out.
that leaves us with x-11.
Hope this helped!

Which of the following values of x will result in an imaginary number for
√2x+7
x ≤ -4 will result in an imaginary number. (From the graph it's actually 3.5, so if you want to view in REAL number then it's x ≤ -3.5 which will result in imaginary numbers.)
But if you want an integer then It's x ≤ -4
Real Number as it's x ≤ -3.5

If the ratio of the length of a rectangle to its width is
9/4 and it’s length is 18 cm, what is the width of the rectangle?
9514 1404 393
Answer:
8 cm
Step-by-step explanation:
It is convenient to write the proportion with the unknown (width) on top:
width/length = 4/9 = w/(18 cm)
Multiplying by 18 cm gives ...
w = (18 cm)(4/9) = 8 cm
The width of the rectangle is 8 cm.
Answer:
The answer is 8.
Step-by-step explanation:
I did a test with this question on it.

Round 4,287,965 to the nearest thousand
Answer:
It is 4,288,000.
Step-by-step explanation:
To round to the nearest thousand, you need to find the thousands place. In the thousands place there is a "7". Okay, we've found it, so the next step is rounding.
To round, there is a handing phrase that we can use to know whether we should round the place up or down. It is "4 or less, let it rest. 5 or more, add 1 more." We need to apply this phrase to the number behind the place we need to round (so apply it to the place behind the thousands place).
When we look behind the thousands place, we see there is a 9. Apply the rule to that. Since 9 is above 5 and not less than 4, we need to add one more to the thousands place.
That means after we round, the 7 turns into a 8. That's how you get 4,288,000.
Hope this makes sense <3

and are independent Gaussian (Normal) random Variables. has mean 13.9 and variance 5.2; has mean 6.9 and variance 3.8. . (a) Calculate
This question is incomplete, the complete question is;
X and Y are independent Gaussian (Normal) random Variables. X has mean 13.9 and variance 5.2; Y has mean 6.9 and variance 3.8. . (a) Calculate P( W> 10)
Answer:
P( W> 10) is 0.1587
Step-by-step explanation:
Given that;
X ⇒ N( 13.9, 5.2 )
Y ⇒ N( 6.9, 3.8 )
W = X - Y
Therefore
E(W) = E(X) - E(Y)
= 13.9 - 6.9 = 7
Var(W) = Var(X) + Var(Y) -2COV(X.Y)
[ COV(X,Y) = 0 because they are independent]
Var(W) = 5.2 + 3.8 + 0
= 9
Therefore
W ⇒ N( 7, 9 )
so
P( W > 10 )
= 1 - P( W ≤ 10 )
= 1 - P( W-7 /3 ≤ 10-7 /3 )
= 1 - P( Z ≤ 1 ) [ Z = W-7 / 3 ⇒ N(0, 1) ]
from Standard normal distribution table, P( Z ≤ 1 ) = 0.8413
so
1 - P( Z ≤ 1 ) = 1 - 0.8413 = 0.1587
Therefore P( W> 10) is 0.1587
