Answer:
<h3>Q1</h3>
Angles forming a linear pair are supplementary and sum to 180°
- x + 8x = 180°
- 9x = 180°
- x = 20°
The smaller angle is 20°
<h3>Q2</h3>
A(-2, 10) reflected over x-axis
<u>Rule for such a reflection is:</u>
<u>Point A will map to:</u>
Correct option is D
<h3>Q3</h3>
One point is at the origin and two other points are at the distance m horizontally and vertically from the origin
<u>The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:</u>
Answer:
2
Step-by-step explanation:
xy/z where x = 3 y = -4 and z = -6
Step 1. Substitute x for 3 y for -4 and z for -6
(3)(-4)/(-6)
Step 2. Multiply
-12/-6
Step 3. Remove the negative signs (only when the numerator and the denominator are both negative numbers)
12/6
Step 4. Simplify
2
Using the y=mx+b format,
m the slope = (5--9)/(8--12) = 14/20 = 7/10=0.7
y-y1 = m(x-x1)
y-5 = .7(x-8) = .7x-5.6
y = .7x +0.6
10y = 7x + 6
so 7x - 1y = -6 any your equation is almost correct.
Answer:
(x-3)(x-9)
Step-by-step explanation:
first thing you need to do is move the -6 over. so we're going to add 6 to both sides (we add because it's negative 6 and we need 0 on the right side)
so you have: x^2-12x+27
now we need to come up with two numbers that add to -12 and multiply to 27.
the factors of 27 are 9 & 3 and 27 & 1. only 9 & 3 add to 12 so we are going to use those.
since the 12 is negative however, 9 and 3 should both be negative.
therefore we get: (x-3)(x-9)
*it doesn't matter which order you put them in!
