Answer:
Step-by-step explanation:
sin(x)=cos(x) × tan(x)
=(-2√23)×(√24)
=(-2√23)×(2√6)
=(-4√138)
=(-4(2√(3×23)))
=(-8√69)
f(x)=-2x+4
what is x when f(x)=-8
Answer:
20
Step-by-step explanation:
f(x) = -2 (x) + 4 (substitute x for the given value)
f(x) = -2 (-8) + 4 (multiply -2 and -8)
f(x) = 16 +4 (add 16 and 4)
f = 20
If LN = 6x - 5, LM = x + 7, and MN = 3x + 20, find MN
Answer:
68
Step-by-step explanation:
LM + MN = LN
x + 7 + 3x + 20 = 6x - 5
4x + 27 = 6x - 5
-4x -4x
27 = 2x - 5
+5 +5
32 = 2x
÷2 ÷2
16 = x
MN: 3x + 20
3(16) + 20
48 + 20

What are the values of x and y in the following system of equations?
[tex]x+y=15[/tex]
[tex]y-x=5[/tex]
Step-by-step explanation:
By elimination method,
x+y=15
-x+y=5
------------
2y=20
i.e y=10
Now,
x+y=15
or, x+10=15
or, x=5
Find f (x )if f apostrophe apostrophe (x )equals x to the power of negative 2 end exponent comma space x greater than 0 comma space f (1 )equals 0 and f (2 )equals 0.
Step-by-step explanation:
Given [tex]g'(x) = g^{-2}, x> 0\ g(1) = 0 \ and \ g(2) = 0[/tex]
To get g(x), we will have to integrate g'(x)
[tex]g(x) = \int\limits {x^{-2}} \, dx\\ g(x) = \frac{x^{-2+1}}{-2+1} + C\\ g(x) = -x^{-1} + C\\g(x) = -x^{-1} + C\\[/tex]
If g(1) = 0, this means at x = 1, g(x) = 0
0 = -1⁻¹ + C
C= 1
Substitute C = 1 into the function
g(x) = -x⁻¹ + 1
If g(2) = 0, this means at x = 2, g(x) = 0
0 = -2⁻¹ + C
C= 2⁻¹
C = 1/2
Substitute C = 2 into the function
g(x) = -x⁻¹ + 1/2
x = -11 + 7y
5x + 2y = -18
Answer:
x = -4
y = 1
(-4,1)
Step-by-step explanation:
x = -11 +7y
5x + 2y = -18
This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18
5(-11 +7y)+2y = -18
5(-11) = -55
5(+7y) = 35y
-55+35y+2y = -18
Now you add 35y and 2y which gives you 37y
-55+37y = -18
Now you add +55 from -55 and -18
37y = 37
You divide each side by 37 so that y = 1
Now you plug y(1) into the equation x = -11+7y
x = -11+7(1)
-11+7 = -4
x = -4

Find x if a = 13 and C = 47.
Answer:45.167
Step-by-step explanation:
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)
Solve for x by answering the number below/
Answer:
The value of x is 5.
Step-by-step explanation:
In a square, all sides are equal so you can compare the expressions to solve x :
[tex]4x - 2 = 2x + 8[/tex]
[tex]4x - 2x = 8 + 2[/tex]
[tex]2x = 10[/tex]
[tex]x = 5[/tex]
Help! Got it wrong after trying first time and need helppp !
We are given the equation:
DA - 2qA = B³
Taking 'A' common on the LHS
A(D - 2q) = B³
Dividing both sides by (D - 2q)
A = B³ / (D - 2q)

Answer:
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
Answer:
Step-by-step explanation:
c = 0.5t + 2
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20
c = 0.5(30) + 2 ⇒ c = 17
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36
