Answer:
- The statement is <em>false</em>
- There is<em> no solution</em>
Step-by-step explanation:
Step 1: <em>Collect the like terms</em>
2x+7 = -8x-9+10x
2x+7 = 2x-9
Step 2: <em>Cancel</em><em> </em><em>equal</em><em> </em><em>terms</em><em> </em><em>of</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em>
2x+7 = 2x-9
7 = -9
Result: The statement is <em>false</em> and there is <em>no solution</em> as 7 is <em>not equal</em> to -9.
I hope this helped ! ;)
Answer:
Graphing
Step-by-step explanation:
1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.
M=3
X=x
B=-1
On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.
This would only give you one line which wouldn't give you an intersection.
The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
Because the triangles are congruent we know that NM = ST = 50.
answer: 50
