The y-intercept of the exponential function is - 2 less than - the y-intercept of the linear function.
Each time in the table the output has 4 more than the previous output, so just subtract 8 from the from the 20 output to find out that the y-intercept is 12.
The y-intercept is represented on the graph at the point where y=0 which is 10 by the way.
10 is 2 less than 12.
Step-by-step explanation:
ln(x) + ln(x + 25) = 0
ln(x(x + 25)) = 0
ln(x² + 25x) = 0
ln(x² + 25x) = ln(1) , x ≥ 0
x² + 25x = 1
x² + 25x + 625/4 = 1 + 625/4
(x + 25/2)² = 629/4
x + 25/2 = ±√(629/4)
x = ( -25 ±√629)/2
x = (-25 - √629)/2 atau ( -25 + √629)/2
(-25 - √629)/2 ≥ 0 NOT PROVED
(-25 + √629)/2 ≥ 0 PROVED
Solution → x = (-25 + √629)/2
Answer:
27a³ -8
Step-by-step explanation:
A binomial has two terms. If one of the terms is the constant -8, the other must be a cubic term, something with a variable to the third power.
27a³ -8 . . . . . a cubic binomial with a constant of -8
Answer:
-7 increased by 7 (-7+7=0)
7 decreased by 7 (7-7=0)
Step-by-step explanation:
The others were wrong, I showed what they added up to.
7+0=7
7-0=7
-7-7=-14
Answer:
x=-6
Step-by-step explanation:
substitute f(x)=0
0=1/3x+2
solve for x
x=-6
