Answer:
y = 2/3x+2
Step-by-step explanation:
The children had 2 puzzles with 226 pieces and 4 puzzles with 558 pieces. How many pieces were in the puzzles altogether?
Answer:
2884 pieces
Step-by-step explanation:
First you have to multiply 2 and 226:
2 x 266 = 532
Then you have to multiply 4 and 558:
4 x 558 = 2352
After that you have add those two to make your answer:
532 + 2352 = 2884
There is your answer.

Step-by-step explanation:
Use the diagram and the given information to find the given length
Answer:
Let x = BC
then by given condition
[tex]\frac{x}{12} = \frac{24}{18}\\x = \frac{12*24}{18}\\x = \frac{48}{3} = 16[/tex]

If:
BC= 4x + 2,
AB = 8x + 8, and
AC = 22,
Find BC.
Answer:
BC = 6.8
Step-by-step explanation:
The distance from A to B, then from B to C, is the same distance as from A to C.
Thus,
AB + BC = AC
AB = 8x + 8
BC = 4x + 2
AC = 22
AB + BC = AC
(8x + 8) + (4x + 2) = 22
Expanding the parenthesis:
8x + 8 + 4x + 2 = 22
8x + 4x + 8 + 2 = 22
12x + 12 = 22
Subtracting 12 from both sides:
12x = 10
Dividing both sides by 12:
x = 10/12 = 1.2
x = 1.2
We're looking for BC. As we know,
BC = 4x + 2
Let's now put in x = 1.2 into this equation:
BC = 4x + 2
BC = 4 * 1.2 + 2
Since 4 * 1.2 is 4.8:
BC = 4.8 + 2
BC = 6.8
Answer: BC = 6.8
(-4f + 9) - (8f + 9) =
Math pls help
Answer:
[tex]-12f[/tex]
Step-by-step explanation:
First, expand the equations with the distributive property. [tex](-4f+9)[/tex] becomes [tex]-4f+9[/tex]. [tex]-(8f+9)[/tex] becomes [tex]-8f-9[/tex]. Now create the expanded version of the equation, [tex]-4f+9-8f-9[/tex]. This becomes [tex]-12f[/tex].

cot^2(x) - csc^2(x) = -1
show steps
Answer:
See proof below
Step-by-step explanation
cot^2(x) - csc^2(x) = -1
In trigonometry identity
cot^2x = cos²x/sin²x
Csc²x = 1/sin²x
Substitute into the original expression
cos²x/sin²x - 1/sin²x
Find the LCM
(Cos²x-1)/sin²x .... *
Recall that sin²x+cos²x = 1
Sin²x = 1-cos²x
-sin²x = -1+cos²x
-sin²x = cos²x-1 .... **
Substitute ** into *
(Cos²x-1)/sin²x
-sin²x/sin²x
= -1 (RHS)
Therefore cot^2(x) - csc^2(x) = -1 (Proved!)

Find two numbers the quotient between. Then estimate the quotient. 41÷3
Answer:
The quotient is between 10 and 15, and the exact answer is 13 with the remainder of 2: 13R2.
Step-by-step explanation:
41 ÷ 3 is a very long answer so do 39 ÷ 3 which equals 13 and since you can't divide 2 by three without negatives, just do it as a remainder of 2, or R2, which means the answer is 13 with the remainder of 2, or just 13R2.

Cos G =
5/12
12/13
5/13
12/5
Answer:
[tex]\boxed {\boxed {\sf cos(G)=\frac{5}{13} }}[/tex]
Step-by-step explanation:
First, recall the trigonometric ratios.
sin(θ)=opposite/hypotenuse cos(θ)= adajcent/hypotenusetan(θ)=opposite/adjacentThe question asks us to find the cosine of G. Therefore, we need the adjacent side and the hypotenuse.
Adjacent: 5 is the side next to angle G (12 is opposite, but we don't need that for cosine).Hypotenuse: 13 is the hypotenuse because it is the largest side and opposite the right angle.Substitute the values into the ratio.
[tex]cos(G)= \frac{adjacent}{hypotenuse}[/tex]
[tex]cos(G)=\frac{5}{13}[/tex]
This fraction cannot be reduced further, so it is the answer.
The cosine of G is 5/13

Answer the question above
Answer:
[tex]tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)[/tex]
Option A is correct.
Step-by-step explanation:
We need to find equivalent of [tex]tan\:\left(\frac{5\pi }{6}\right)[/tex]
First we solve [tex]tan\:\left(\frac{5\pi }{6}\right)[/tex]
We get [tex]-\frac{1}{\sqrt{3} }[/tex]
Now checking all the options.
Option A: [tex]tan\:(-\frac{\pi}{6} )[/tex]
Solving [tex]tan\left(-\frac{\pi }{6}\right)\: we\: get\: \mathbf{ -\frac{1}{\sqrt{3} }}[/tex]
Option B: [tex]tan\left(\frac{7\pi }{6}\right)[/tex]
Solving [tex]tan\left(\frac{7\pi }{6}\right)\: we\: get\: \mathbf{\frac{1}{\sqrt{3} }}[/tex]
Option C: [tex]cot\left(\frac{5\pi }{6}\right)[/tex]
Solving [tex]cot\left(\frac{5\pi }{6}\right)\:we\:get\:\mathbf{-\sqrt{3} }[/tex]
Option D : [tex]tan\left(-\frac{5\pi }{6}\right)[/tex]
Solving [tex]tan\left(-\frac{5\pi }{6}\right) \:we\:get:\mathbf{\frac{1}{\sqrt{3} } }[/tex]
So, looking at the options, only Option A has the same result as given question
So, [tex]tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)[/tex]
Option A is correct.
