Step-by-step explanation:
If you look at the large triangle, you will see that the side is opposite of 30° angle and the side 15 is opposite of 90° angle (<em>side opposite of 90° angle is called the hypotenuse</em>).
We have the angle, we have the side opposite and the hypotenuse. Which trigonometric ratio relates opposite side and hypotenuse? SINE!
<em>So we use the sin ratio and cross multiply and solve for :</em>
Hence,
Answer:
You got your negatives messed up. The answer was -5y-4x
Step-by-step explanation:
Expression: -8y + 5x + 3y -9x
Your objective: Simplify the expression
The First step, Combine like terms meaning -8y+3y and -9x+5x
Solve, -8y+3y
That would equal -5y
Next solve -9x + 5x
That would equal -4x
Write your expression in simplest form:
-5y-4x
What you did:
You combined like terms but didn't follow the negative rules
Remember: Positive and Negative = Negative
Negative and Negative = Positive
For example -8y + 3y
You chose to add -8 and 3 which you got -11
What you were supposed to do was to subtract.
A helpful trick: Since they are like terms you could rearrange the questions like this 3y-8y+5x-9x, You can see that you have to do subtraction left to right
3y-8y= -5y
5x-9x= -4x
Solution: -5x-4x
<span>If you put the 9cm and 2cm rods together end-on-end, the new length is 11cm. Now if you repeat this with the 7cm and 5cm rods that new length is 12cm, so the difference between the two is now 1 cm. It does not seem very practical to walk around measuring items using the rods like this, so you could then make a small rod or use a strip of paper equal to the difference (1cm) as a standard measuring tool.</span>
Slope is calculate using the following equation:
slope = (y2-y1) / (x2-x1)
since the slope is undefined, therefore, the denominator is equal to zero, which means that x2 = x1.
Based on this, the only curves with undefined slopes are the curves with equation: x = constant
Therefore, <span>equation of a line passing through a point (5,-3) with and undefined slope is x = 5</span>
