Solve the system using substitution . y =2x +4 , 2x - y = 6
babymother [125]

no solution

substitute y = 2x + 4 into the other equation

2x - (2x + 4) = 6 ( distribute and simplify )

2x - 2x - 4 = 6 ( add 4 to both sides )

0 = 10 ← not possible

Hence the system has no solution

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
oksian1 [2.3K]

Answer:

-3 is the value of k in g(x)=kf(x)

Step-by-step explanation:

Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:

g(x)=kf(x)

g(-3)=kf(-3)

To solve this for k we will need to find the values for both g(-3) and f(-3).

g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.

g(-3)=-3

f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.

f(-3)=1

So our equation becomes:

g(-3)=kf(-3)

-3=k(1)

-3=k

So k=-3.
