(-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).
Final answer:
The value of the expression is 31.
Step-by-step explanation:
Substitution is a process of putting the values of variable in the expression.
Given: p=17 and q=3
To find: value of 2p-q
We will substitute the values and simplify.
Putting the values of variables in the expression as
2p-q = 2x17-3 =34-3 = 31

Answer:
75 general
105 student ID
Step-by-step explanation:
(it's a system)
4x+3y=615
x+y=180
(system as well)
4x+3y=615
x=180-y
4(180-y)+3y=615
720-4y+3y=615
-y=-105
y=105
x+105=180
x=180-105
x=75
{-3. -2. -1 , 0, 1, 2}
