Answer:
x=1
Step-by-step explanation:
log_4(x + 3) + log_4x = 1
We know that loga(b) + loga(c) = loga(bc)
log_4(x + 3)x = 1
Raise each side to the base of 4
4^log_4(x + 3)x = 4^1
(x+3)x = 4
x^2 +3x = 4
Subtract 4 from each side
x^2 +3x -4 = 0
Factor
(x+4) (x-1) =0
Using the zero product property
x= -4 x=1
But x cannot be negative since logs cannot be negative
x=1
Answer:
<h2>y = 2x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
=======================================
We have the points (-2, 1) and (-4, -3). Substitute:
Put the coordinates of the point (-2, 1) to the equation:
<em>add 4 to both sides</em>
Finally:
Well, there are 13 places that each horse can place. That means the first place has 13 options, second place has 12 options, third place has 11 options, etc. Though, we only care up to fourth place. When doing probability, we're multiplying in this case. So, here's the process:
How many ways all the horses can place = 13! = 6227020800
How many ways the first four places can place = 13*12*11*10 = 17160
Divide the second by the first and multiply by 100 for the probability as a percent:
(17160/6227020800)*100% ≈ <span>0.00027557319%

(x+1)²+(y+1)²=9
the answer can be found with
(x-h)²+(y+k)²=r²
where the point (h,k) is the center.
Answer:
its 13 if i saw the numbers right
Step-by-step explanation:
evaluate then you get the below
1-(-4)x(-3)+12/(-6)
___________
-1
divide and get;
-(1-(4)x(-3)+12/(6))
remove parentheses and divide
-(1+4x(-3)-2)
multiply and get
-(1-12-2)
calculate
-(-13)
remove "()"
and you get 13
