y=sin(x+60)
y=sin(x)
Answer:
Step-by-step explanation: -4.5=a-8
1. add 8 to both sides -4.5+8= 3.5
2. since you added 8 to negative 8 you get zero so it just goes away
3. ANSWER= 3.5=a
Sorry i don’t understand how to do C but this is what i have and my work hope it helps :)
Answer:
Step-by-step explanation:
first we put them in y = mx + b form...then we compare the slopes and the y int's. In y = mx + b form, the slope is in the m position and the y int is in the b position.
2x + 2y = 8
2y = -2x + 8
y = -x + 4......slope here is -1 and y int is 4
3x + y = 8
y = -3x + 8.....slope here is -3 and y int is 8
This system has 1 solution <===
================================
learn this...it helps
* if there are different slopes and different y int, then there is 1 solution
* if there are the same slopes and different y int, then there is no solutions because u have parallel lines
* if there are same slopes and same y int, there is infinite solutions because u have the same line
