1. 3x - 3y = 9
to find the x or y intercept, multiply the other variable that you are not tryng to find by 0
3x - 3(0) = 9 3(0) - 3y = 9
3x = 9 -3y = 9
3x/3 = 9/3 -3y/-3 = 9/-3
x = 3 y = -3
2. I did the same thing for the rest
x = 6 y = -2
3. x = 2.5 y = -5
4. x = -4 y = -2/3
Answer:
<em>The answer to your question is Domain is 2. Then the range is 4..</em>
Have a wonderful day, and I hopes it helps! I wasn't exactly sure about my answer, but I'm sure that it is right! ^^'
Step-by-step explanation:
1. -9x - 3 - 3 + 2x
-7x - 6
3. 3 - 4x - 7x - 2
-11x - 1
4. 5x - 1 + 3 + 2x
7x + 2
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
The height is 22 inches? It says it in the question
