Answer:

(-10,-7)

Step-by-step explanation:

Lets start with the equation y>-3x+7

Which of these are solutions?

(5,-5) - yes

(10,-8) - yes

(5,-6) - yes

(-10,-7) - no

Now lets do the equation y<4/5x-2

Which of these are solutions?

(5,-5) - yes

(10,-8) - yes

(5,-6) - yes

(-10,-7) - no

So, the point (-10,-7) is not a solution to the system of equations.

Answer:

41º

Step-by-step explanation:

An angle bisector splits an angle in half. So angle LKM+angle MKJ=angle LKJ. We know angle LKJ=82º, so angle LKM=angle MKJ=82º/2=41º.

Answer:

I disagree. Open book tests, you can see the answers, and the test usually goes by pretty quick and smoothly because of this. Traditional tests, sometimes you don't even get notes, and so you can struggle more with that then with open book tests.

Step-by-step explanation:

I got 100% on Edge!

Answer:

I believe that open book test are easier simply because the answers are right in front of you all you have to do is search for them and not copy directly from the book. One way you can prepare for it is to memorize what information is on each page so you don't constantly flip back and forth from the pages

Step-by-step explanation:

Answer:

Step-by-step explanation:

a). [tex]\text{cos}^4(\frac{\theta}{6})-\text{sin}^4(\frac{\theta}{6})=\text{cos}\frac{\theta}{3}[/tex]

   By solving left hand side of the equation,

   = [tex][\text{cos}^2(\frac{\theta}{6})-\text{sin}^2(\frac{\theta}{6})][\text{cos}^2(\frac{\theta}{6})+\text{sin}^2(\frac{\theta}{6})][/tex]

   = [tex][\text{cos}^2(\frac{\theta}{6})-\text{sin}^2(\frac{\theta}{6})](1)[/tex] [Since, cos²a + sin²a = 1]

   = [tex]\text{cos}\frac{\theta}{3}[/tex] [Identity used → cos²a - sin²a = cos(2a)]

Hence, left hand side of the given equation = Left hand side of the equation.

Answer:

Step-by-step explanation:

Answer:

These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.

Step-by-step explanation:

We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.

[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]

Now we can plug that into our first equation to find x

[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]

So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

Answer:

6

Step-by-step explanation:

4.5 dived by 3/4 equals 6

Answer:

x = 31

Step-by-step explanation:

The 2 sides are congruent, meaning the 2 angles are equal so:

47 = x + 16

subtract 16 from both sides

31 = x

Answer:

Use the associative property of multiplication to rewrite (5 x 4) x 3 In order to rewrite the expression, take the parenthesis off of the first two factors and put them around the last two factors. Answer: 5 x (4 x 3) Example: Use the associative property of multiplication to rewrite (6 x 2) x 7

Answer:

B

Step-by-step explanation:

3x^2+7/3x-8

Answer:

I'm assuming your problem looks like this: 4+5*6-3 =? To solve this problem you need to use the order of operations. PEMDAS which stands for Parentheses, exponents, multiply and divide, and lastly add and subtract. You must multiply and divide before you add and subtract so you must do 5*6 first. You now get 4+30-3. Now all you have left is addition and subtraction so you now just go from right to left and do one at a time. So 4+30 = 34 , 34-3=31. Therefore your answer should be 31. Hope that helped!
