Answer:
open circle on negative 10 with the arrow going to the right. one trick is when the variable is on the left the inequality sign points to where the arrow will go and > is open circle > with a line under is closed circle
Answer:
That's the exponential function.
Step-by-step explanation:
Simply just use a graphing calculator (there's plenty of apps and websites that are graphing calculators) and follow these steps.
1) Clear out calculator RAM
2) Press STAT button
3) Press ENTER on EDIT
4) Type the X's in L1 and type the Y's L2.
5) Press STAT again
6) Press the RIGHT ARROW once
7) Press 0
8) Press ENTER
9) There's your exponential function!
3x-7=14
Hoped this helped!
Answer:
14
Step-by-step explanation:
To find x, you will need to use sine. If you want to find y, use cosine:
sin 45 = x / 14 sqrt(2)
x = 14
(Since this is a 45 45 90 special triangle, x and y have the same length)
Since I talk about special triangles, 45 45 90 triangles are very simple:
To find the other two side lengths, just divide the hypotenuse by sqrt 2
14 sqrt(2) / sqrt(2) = 14
So both ways will still lead to 14
6x - 42 + x = 15 +9x + 5 ;
7x - 42 = 20 + 9x;
7x - 9x = 20 + 42;
-2x = 62;
x = -31;
