Hi! Your answer is 343.8
I hope this is helpful!
(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.
Option B
<u>Step-by-step explanation:</u>
Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:
First look at where we have intersection points, In first quadrant & in third quadrant.
<u>At first quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)
<u>At Third quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y= -2.0. So, other point is (-1.2,-2.0).
Answer: -.6
Step-by-step explanation: Isolate t
In order to keep the equation equal, what is done to one side must be done to the other
1. You would subtract 1.5 from each side so you end up -3t = 5
2. Divide -3 from both sides, you are left with t = -.6 which is your answer
<span>3x + y= 17 (a)
4x + 2 y = 20 (b)
Multiply (a) by 2:
6x + 2y = 34 (a)
4x + 2y = 20 (b)
make: (a) - (b)
2x = 14 -----> x =7
-------------------------------
Replace the value of x = 7 in one of anterior equation:
</span>3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
