Answer: 1)c. -6
2)B.4
Step-by-step explanation:
1)It would be: -4(3r - 2) - 2(r+1)
= -12r + 8 - 2r - 2
= -14r + 6
2)When we have an equation like 1x, and x = 2, then that means that we are multiplying by x or 1 * x. So, a = 2 and b = 3, we have to multiply 3 & 2 by 2, and 2 by b. (3 * a(2) ==> 6) ~~ (2 * 2 ==> 4) ~~ (2 * 3 ==> 6) Now, we have 6 - 6 + 4. Evalutate. (6 - 6 ==> 0) ~~ (0 + 4 ==> 4) 4 is the final
Answer:
It is reflection
Step-by-step explanation:
We know these three rules:
-a rotation followed by a rotation is a rotation
-a reflection followed by a reflection is also a rotation
-a rotation folowed by a reflection is a reflection
So we have: f3r3 is f (reflection)
f2 f is r (reflection)
r3 r is r
f2 r is f
r2 f is f
r1 f is f
So, r1r2f1r3f2f3r3 is reflection.
Answer:
See attachment showing the rise and run
Slope = 1
Step-by-step explanation:
In the diagram attached below, the rise is represented by the blue line, while the run is represented by the red line.
Rise = 4 units
Run = 4 units
It's a positive slope because the line slopes upwards from left to right
Slope = rise/run = 4/4
Slope = 1
Answer:
The solution is (0, 3)
Step-by-step explanation:
First, reduce 2x + 4y = 12 to x + 2y = 6, for easier calculations.
Next, substitute y - 3 for x in the other equation:
y - 3 + 2y = 6, or
3y = 9
Then y = 3. Since x = y - 3 in general, x = 3 - 3 = 0 when y = 3.
The solution is (0, 3)
Angle B would be equal to angle E
