Answer:
2. (b) ∠ZYX
3. (b) noncollinear
Step-by-step explanation:
2. An angle is named by naming the two rays that make it up. The vertex (common end point of the two rays) is named in the middle.
Here, the rays making the angle are YX and YZ. The angle could be named either ∠XYZ or ∠ZYX.

3. Points not on the same line are <em>noncollinear</em>. Point E does not lie on line AB, so points A, B, and E are noncollinear.
Answer:
The line you're looking for is parallel to y = 3x – 9, so it also has a slope of 3. Thus, you can rule out ... Here's what your work should look like: y = mx + b 0 = 3(–3) + b 0 = –9 + b 9 = b Now that you know both the slope and the y-intercept for this line, you can write the equation in the slope-intercept form: y = mx + b y = 3x + 9 The correct answer is Choice (C). What is the equation of a line that passes through the point (0, 3) and is perpendicular to y = 8x + 5? (F) y = 8x (G) y = 8x + 3 (H) (J)
Step-by-step explanation:
-144= -1×2a×3b
144=2a×3b
144= 6ab
24= ab
a,b could b any two factors that have a product of 24
For example a,b could = 6,4 or 8,3 or 24,1
Answer:
This question is tricky because it could have multiple answers: for example is a,b= 6,4 then a+b= 10, but if a,b=24+1=25. So, the answer is that the sum of a+b varies depending on which 2 factors of 24 a and b are equal to. Does this make sense?
When they work together, it takes John 1/x hours and it takes Brian 1/(x+15) hours to complete 1/4 of the model.
1/x + 1/( x+15 ) = 1/4 / · x ( x+15 )
x+15 + x = x ( x+15 ) /4 / · 4
8 x + 60 = x² + 15 x
x² + 15 x - 8 x - 60 = 0
x² + 7 x - 60 = 0
x² + 12 x - 5 x - 60 = 0
x · ( x + 12 ) - 5 ·( x+ 12 ) = 0
( x + 12 ) · ( x - 5 ) =0
x = - 12 ( not accepted ) or x = 5
The time taken by Brian: 5 + 15 = 20 hours
ANSWER: 1.562
move the decimal point of 0.0034 to the right to make it a whole number which is 34. Then multiply 34 times 430 which is 15,620.
move the decimal point (which is at the end) 4 times to the left
the answer will be 1.562
