The domain 2 would be plugged in as f (2)=2x+1 which equals 5
Given:
The measures of the angles in a triangle are in the ratio of 2:2:4.
To find:
The exterior angle that is adjacent to the largest angle.
Solution:
Let the interior angles of the triangle are 2x, 2x and 4x respectively.
According to the angle sum property, the sum of interior angles of a triangle is 180 degrees.
Clearly, x=22.5>1, so 4x is the largest angle between 2x, 2x and 4x.
Now,
Let the required exterior angle that is adjacent to the largest angle be y.
Interior angle and adjacent exterior angles are supplementary, so their sum is 180 degrees.
Therefore, the exterior angle that is adjacent to the largest angle is 90°.
Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
Step-by-step explanation:
The answer for the first box is independent variable because the independent variable is a constant value and is usually of x-coordinate.
The cost is the dependent variable because the y-value depends on the change in x-value. It is given that the cost varies as the time increases. Hence, cost is a dependent variable.
Also, the costing of renting depends on the number of hours rented, since cost is a dependent variable and the the cost raises if the time rented increases.
Thus, Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
-6 + 6 = 0
0 + -2x = 12 + 6 -2x = 12 + 6<span>4x+2(x-3)=8x+12 is our main problem right? so...
</span><span>4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12
</span><span>So next we do:
</span><span>-6 + 4x + 2x = 8x + 12
Reorder the terms :) </span><span>-6 + 6x = 12 + 8x
</span>Now were going to solve for x
<span>-6 + -2x = 12 + 8x + -8x
</span><span>8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12
</span>-6 + 6 = 0
0 + -2x = 12 + 6
-2x = 12 + 6=
<span>-2x = 18
so now were just going to divide each side by -2
and so thats going to be like this
-2x = 18</span>
/ -2 /-2
0 -9
so whats left over is x = -9
So your answer is A.
