Okay, it's the equation to how find area any other way. A=L×W

This means *picture above*

So then you count over each line meaning 1.
This means L=9 and a 1/2. Since its in between the 2 an 3 on the x-axis.
Now for W or width. It equals 3 since you can count 2 lines and one either ends of the polygon is 1/2 each this creates one when added together.

All you do from there is multiply 9 and 3. This should give you A=area.

Solve for the value of X in 9^x+4(3^x+1)+27=0​
worty [1.4K]

Answer:

No solutions

Step-by-step explanation:

9^x + 4(3^x + 1) + 27 = 0\\3^{2x} + 4 \cdot 3^x + 31 = 0

Substitute 3^x with t and we get.

t^2 + 4t + 31 = 0\\\triangle = 16 - 4 \cdot 31 = -108 < 0 => t_{12} \notin R => x \notin R

What is the approximate solution of the linear system represented by the graph below
VashaNatasha [74]
ANSWER

The approximate solution is

(4, - 1)

EXPLANATION

The point of intersection of the two lines is the solution of the linear systems represented by the graph.


From the graph we can determine that each box is 2 units.


From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be
(4, - 1)


Note that since each box is two units, half way between the boxes gives one unit.
