Answer:
![x = + - 7\sqrt{2 + 7}](https://tex.z-dn.net/?f=x%20%3D%20%20%2B%20%20-%20%20%207%5Csqrt%7B2%20%2B%207%7D%20)
or in decimal form:
x = 16.89 , -2.89
You get this by completing the square.
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
1 = b
Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
