Answer:
9x+3
Step-by-step explanation:
First join the x terms, and you will find 9x (1x+8x), then join the numbers, and you get 3 (-7+10)
Hope it helps!
<h3>
Answer:</h3>
- x-intercept: 82.75
- y-intercept: -2.15
<h3>
Step-by-step explanation:</h3>
To find the x-intercept, set y=0 and solve.
... 0 = log(12x +7) -3
... 3 = log(12x +7) . . . . add 3
... 1000 = 12x +7 . . . . take the antilog. (10^3 = 1000)
... 993 = 12x . . . . . . . .subtract 7
... 82.75 = x . . . . . . . . divide by 12
To find the y-intercept, set x=0 and solve.
... y = log(12·0 +7) -3
... y = log(7) -3 . . . . . . simplify
... y ≈ 0.85 -3 = -2.15 . . . . use a calculator for the log function
<em>10 inches</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em><u>volume of a sphere formula</u></em>
<em>V = 4π·r³/3</em>
<em>3V = 4π·r³</em>
<em>r³ = 3V/4π</em>
<em>replace</em>
<em>r³ = (3·500π/3)/4π</em>
<em>= 500π/4π</em>
<em>= 125</em>
<em>r³ = 125</em>
<em>r³ = 5³</em>
<em>r = 5 inches</em>
<em>d = 2r = 2×5in = 10 inches</em>
<em>Good luck !</em>
12.9/ .6= is 21.5 hope this is what you need!!:)
