Answer:
2
Step-by-step explanation:
if you get a pizza and cut it to 9 pieces you get 2 slices the fraction is 9/2
4 - (x+2) < -3(x+4)
4 -1(x) -1(2) < -3(x) -3(4)
4 - x - 2 < -3x -12
<u> +3x +3x </u>
<u />2 + 2x < -12
<u>-2 -2
</u> 2x < -14
<u /> <u> ÷2 ÷2 </u>
x < -7
assume that x = -8
4 - (-8 + 2) < -3(-8 + 4)
4 - (-6) < -3(-4)
4 + 6 < 12
10 < 12 the inequality is true.
Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y
10% left handed
90%(9/10) right handed

Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
