Answer:
11. x = 5
12. x = 24
Step-by-step explanation:
11.
8x° + 140° = 180°
(Linear pair angles)
8x° = 180° - 140°
8x° = 40°
x ° = 40°/8
x° = 5°
x = 5
12.
2x° + 42° = 90°
(complementary angles)
2x° = 90° - 42°
2x° = 48°
x ° = 48°/2
x° = 24°
x = 24
The answer is C
2.5 + 3.4 = 5.9
So:
5.9 x 10^4
The answer is 66.67% because 2/3 equals .6667. Hope this helps mate :)
The best and most correct answer among the choices provided by your question is the first choice or letter A "y = 3x - 2."
First of all, let's talk about vertical shifts, or shifts along the y-axis. These are transformations that move a function up or down the y-axis, without changing anything else about it.
When you shift a function vertically, you get a new function with the same slope but a different y-intercept. In the equation
y = mx + b
which is the equation for a linear function, this is represented by a change in b.
Just for example, take two functions:
Function 1: y = 2x + 1
Function 2: y = 2x + 3
Function 2 will look exactly like Function 1, except it will be shifted 2 units up on the y-axis, so the y-intercept of Function 2 will be at y = 3 instead of y = 1.
For every 1 that you add to b, the function will move up 1 unit on the y axis. For every 1 that you subtract from b, the function will move down 1 unit.
