3x+6y=12
-3x -3x
6y=-3x+12
*divide by 6 on both sides*
y= -1/2x+2
Slope: -1/2
Y-intercept: 2
Answer is: Radius = 8.6 cm
Answer:
Step-by-step explanation:
<u>This is going to be an arithmetic progression:</u>
- 48500, 48500 + 1200, 48500 + 1200*2, ...
<u>So the first term is </u>
<u>and the common difference is </u>
<u>Sum of AP is:</u>
- S = (a₁ + aₙ)*n/2 = (2a₁ + (n - 1)d)*n/2
<u>Substitute and solve for n:</u>
- (2*48500 + (n - 1)*1200)*n/2 = 321000
- (97000 + 1200n - 1200)n = 642000
- 1200n² + 95800n - 642000 = 0
- 6n² + 479n - 3210 = 0
<u>Solving we get a positive root of:</u>
- n ≈ 6.21 and it rounds up to 7 years
Answer: x = 7/3
Step-by-step explanation:
You join the X’s first which will give you
6x-14 = 0
Then you move the 14 to the right
6x = 14
Then you dived them and it give you 7/3
Hope this helped
B. 17+5x=23+4x-6+x
17+5x=5x+17
0=0
There would be no solution
