The answer to question 5 is -3.
The answer to question 9 is -5.<span>
</span>The answer to question 7 is 28x^3y^4.
Answer:
No, because using the distributive property, you would get 5b+15 and 3b+15. The number of b you have is different.
Answer:
sin(x) = 5/13
cos(y) = 5/12
Therefore, sin(x) = cos(y)
Step-by-step explanation:
Trig ratios:
![sin(\theta)=\dfrac{O}{H}\\\\\\cos(\theta)=\dfrac{A}{H}\\\\\\tan(\theta)=\dfrac{O}{A}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cdfrac%7BO%7D%7BH%7D%5C%5C%5C%5C%5C%5Ccos%28%5Ctheta%29%3D%5Cdfrac%7BA%7D%7BH%7D%5C%5C%5C%5C%5C%5Ctan%28%5Ctheta%29%3D%5Cdfrac%7BO%7D%7BA%7D)
where
is the angle, O is the measure of the side opposite the angle, A is the measure of the side adjacent to the angle and H is the hypotenuse, of a right triangle
We have been given the measures of the two legs, so we can find the measure of the hypotenuse by using Pythagoras' Theorem ![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
(where a and b are the legs and c is the hypotenuse of a right triangle)
![\implies 5^2+12^2=c"\\\\\implies 169=c^2\\\\\implies c=\sqrt{169}\\\\ \implies c=13](https://tex.z-dn.net/?f=%5Cimplies%205%5E2%2B12%5E2%3Dc%22%5C%5C%5C%5C%5Cimplies%20169%3Dc%5E2%5C%5C%5C%5C%5Cimplies%20c%3D%5Csqrt%7B169%7D%5C%5C%5C%5C%20%5Cimplies%20c%3D13)
Now we can use the trig ratios:
![\implies sin(x)=\dfrac{5}{13}](https://tex.z-dn.net/?f=%5Cimplies%20sin%28x%29%3D%5Cdfrac%7B5%7D%7B13%7D)
![\implies cos(y)=\dfrac{5}{13}](https://tex.z-dn.net/?f=%5Cimplies%20cos%28y%29%3D%5Cdfrac%7B5%7D%7B13%7D)
Therefore, sin(x) = cos(y)
Answer:
To calculate 25 percent of a number, simply divide it by 4. For example, 25 percent of 12 is 12 divided by 4, or 3. 10 percent means one tenth. To calculate 10 percent of a number, simply divide it by 10 or move the decimal point one place to the left.
Step-by-step explanation:
Answer:
adjust the equation so the line passes through the points
