Answer:
3[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)
d = [tex]\sqrt{(-3-(-9))^2+(-1-8)^2}[/tex]
= [tex]\sqrt{(-3+9)^2+(-9)^2}[/tex]
= [tex]\sqrt{6^2+81}[/tex]
= [tex]\sqrt{36+81}[/tex]
= [tex]\sqrt{117}[/tex]
= [tex]\sqrt{9(13)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{13}[/tex]
= 3[tex]\sqrt{13}[/tex]
three times the sum of a number and six
3(x=6)
3(x-6)
3(x+6)
3x+6
Answer:
3(x+6)
Step-by-step explanation:
Parenthesis after a number typically means multiply, so 3 times the sum of an unspecified number (x), plus 6 would be 3 (x+6)

Prove this identify :
2 cos^2 (45°-A ) = 1 +sin 2 A
I am guessing that you mean 2cos2(45° - A) = 1 + sin2A
According to a double angle identity, 2cos2θ - 1 = cos(2θ)
So, 2cos2(45° - A) - 1
= cos (90° - 2A) =cos90°cos2A + sin90°sin2A = (0)cos2A + (1)sin2A = sin2
Thus, 2cos2(45° -A ) = 1 + sin2A

Answer:
6^11
Step-by-step explanation:
you have 6 and 6 so it stays 6 and then you add the exponents on this problem which gives u 11
Answer:
6^11
Step-by-step explanation:
In this case the base remains the same but you add exponents. Try it on your calculator
6^5 x 6^6 = 362797056

Perimeter of Triangle Please. Thank you ASAP
Step-by-step explanation:
The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.
The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For the longer side,
[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]
or the shorter side,
[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]
Therefore, the perimeter is given by,
[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]

Help needed please ASAP!
Answer:
B
Step-by-step explanation:
The steps in the original function of f of B are
1. multiply by 2
2. subtract 9
Then the steps of the inverse equation would be
1. add 9
2. divide by 2
And this is what we see here. G is actually the inverse of f. Therefore B is the correct answer. If you repeat the same process for the other answers you'll find that it doesn't actually make an inverse.
You can also graph these to see whether or not its an inverse.
Find the value of x and YZ if Y is between X and Z. You may need to draw a picture. XY = 2x + 1, YZ = 6x, and XZ = 81 X YZ =
Answer:
x= 10
YZ=60
Step-by-step explanation:
X____Y____Z
XZ= XY+YZ
81 = (2x+1) + 6x
81 = 8x +1
8x = 81 -1
8x =80
x = 80/8
x = 10
YZ = 6x = 6(10) = 60

Answer:
-(5/14)
Step-by-step explanation:
Make the denominators the same.
-9/14 (Stays)
2/7(Times by 2 to make denominator 14)
-9/14 + 4/14 = -5/14
Final asnwer is -(5/14)
Answer:
-5/14
Step-by-step explanation:
first make them the same denominator
we can multiply the 2/7 by 2/2 to get 4/14 so it becomes really easy to add :)
-9/14 + 4/14 = -5/14!
it's already in simplest form so there's nothing else you have to do :D

if 3x+ 5y +4z =0 , prove that 27x³ +125y³ +64z³=180xyz
Answer:
Use the following identity:
a³ + b³ + c³ = 3abc if a + b + c = 0Substitute:
a = 3x, b = 5y, c = 4zand get:
(3x)³ + (5y)³ + (4z)³ = 3(3x)(5y)(4z)27x³ + 125y³ + 64z³ = 180xyzWe know
If a+b+c=0

Answer:
[tex]42 = - 48 + 3r[/tex]
add 48 to either sides:
[tex]42 + 48 = ( - 48 + 3r) + 48 \\ 90 = 3r \\3r = 90[/tex]
divide all sides by 3:
[tex] \frac{3r}{3} = \frac{90}{3} \\ \\ { \boxed{ \boxed{r = 30}}}[/tex]
Answer:
r = 30
Step-by-step explanation:
42 = -48 + 3r
First, we will add 48 to both sides so that r can be isolated42 + 48 = -48 + 48 + 3r
Then, we will add90 = 3r
Then to isolate r, we have to get rid of the 3To get rid of the 3, we will divide by 3 on both sides[tex]\frac{90}{3} =\frac{3r}{3}[/tex]

Step-by-step explanation:
If we know that D is the midpoint, then 2x + 7 = 4(x-3). Doing the algebra on that gives us

19 = 2x so
x = 9.5
Please help! What is |x-3|=9
Answer:
x = 12 or x = -6
Step-by-step explanation:
Solve for x over the integers:
abs(x - 3) = 9
Split the equation into two possible cases:
x - 3 = 9 or x - 3 = -9
Add 3 to both sides:
x = 12 or x - 3 = -9
Add 3 to both sides:
Answer: x = 12 or x = -6
