Please help me with these asap, will give brainliest.

brainliest???

Step-by-step explanation:

we have that

y = 2−x

and

y = 4x + 3

we know that

Part a)

the graph of both lines, if it is a system of consistent equations, is going to intersect in a single point that will belong to both lines, so the values ​​of that point will satisfy both equations

part b) see the attached table  

observing the table it is deduced that the solution value of x must be in the interval [-1, 0]

part c)

using a graph tool

see the attached figure

the system is solved graphically, by identifying the point of intersection of both lines

the solution is the point (-0.2, 2.2)
