Answer:
-151
Step-by-step explanation:
first find the value of g(6)
g(6) = -3 × 6 - 8 ➡-24
then put this value fir f(g(6))
f(-24) = 6 × -24 -7 ➡ -151
Answer: -2x + 9
First, Use the distributive property: 3(x+3)-5x (3 multiplied by x is 3x and 3 multiplied by 3 is 9
Next, subtract the variable x: 3x+9-5x (3x-5x=-2x
The answer is -2x+9

Answer:
<h3> The equation has one valid solution and no extraneous of solutions.</h3>
Step-by-step explanation:
Given the expression;
4x/3x+1 = x/2x+10
We are to get the nature of the value of x
Cross multiply;
x(3x+1) = 4x(2x+10)
3x²+x = 8x²+40x
Collect like terms;
3x²-8x² + x - 40x = 0
-5x²+x -40x = 0
-5x²-39x = 0
-5x² = 39x
-5x = 39
x = -39/5
<em>Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.</em>

Answer:
Step-by-step explanation:
8/v=6/v-3
8*(v-3)=6v
8v-8*3=6v
8v-24=6v
+24 +24
8v=6v+24
-6v -6v
2v=24
v=24/2
v=12 miles /hour
v2=12-3=9 miles /hour ( your friend)
