Use f and m for "female" and "male." Then f = m + 16, and f + m = d (total)
So now we have the system of linear equations
f = m + 16
f + m = d
We can eliminate f by subst. m + 16 for f in the second equation:
d-16
m + 16 + m = d, or 2m + 16 = d. Find m. 2m = d - 16, so that m = --------

Assuming that the male horses are either brown or black, and that 25% of these are brown, then the rest must be black. This number is
d-16
0.75 [ --------- ] .

The slope-point form: y - y₁ = m(x - x₁).
The slope-intercept form: y = mx + b.
We have:
and the point (-5, 7)
therefore
Answer:
<em>Use the tangent formula to find x:</em>
tan x° =
<u>x≈36.8699°</u>
cos y° =
The ratios of sin x and cos y are equal to each other:
sin x° =
cos y° =
Answer:
|6x+12|= 12 has <u>2</u> solutions --> <u>x = -4 or x = 0</u>
|6x+12|= -1 has <u>No</u> solutions
∣6x+12∣=0 has <u>1</u> solution --> <u>x = -2</u>
<u>Explanation:</u>
<u>|6x+12|= 12</u>
<em>- Break |6x+12| = 12 down into two equations -</em>
↓
6x + 12 = 12
6x + 12 = −12
<em> - Solve both equations to x -</em>
6x + 12 = 12
6x + 12 = −12
↓
6x = 0
6x = −24
↓
<u>x = 0</u>
<u>x = −4</u>
<u></u>
<u>|6x+12|= -1</u>
The absolute value function is always positive or 0 so false.
<u></u>
<u>∣6x+12∣=0</u>
<em>- Because its 0, we simply just solve the equation -</em>
<em> </em> 6x + 12 = 0
↓
6x = -12
↓
<u>x = -2</u>
<u></u>

Hello there!
The median is
<h2>52</h2>
Step-by-step explanation:
Here's a quick way to find the median.
Just remember "median" and "middle"
the median is always the middle number. :)
Hope this helps! :)
