Answer:
a = 10/3.
Step-by-step explanation:
We write the linear function as follows:
f(x) = mx + b where m is the slope and b is the y-intercept.
f(6) = 6m + b = 8
f(2) = 2m + b = 20 Subtracting these 2 equations:
4m = -12
m = -3.
and -3 * 2 + b = 20 so:
b = 20 + 6 = 26.
So we have the linear function:
f(x) = -3 x + 26
f(a) = 16 = -3 a + 26
-3 a = 16-26
a = -10 * -3 = 10/3.
To solve this we need to use Pythagorean theorem

Answer: x≈6.4
Answer:
Use multiplication and dividing.
Step-by-step explanation:
If you want to convert to a smaller unit, you must multiply.
For example...
4 Feet to Inches:
<em>inches</em>
2 Yards to Inches:
<em>feet</em>
<em>inches</em>
If you want to convert to a larger unit, you must divide.
336 Inches to Feet:
<em>feet</em>
756 Inches to Yards:
<em>feet</em>
<em>yards</em>
I would do linear combinations
if we simplify all of them by dividing the 2nd equation by -2 and the 3rd by 3, we get
x+y+2z=5
x+y+2z=5
x+y+2z=5
which is all the same plane, so there are infnitely many solutions
