Answer:
$855.65
Step-by-step explanation:
Multiply 785 by 0.09 to get the sales tax amount which is 70.65.
Add the sales tax amount to the price of the dining set to get cost after tax.
<u>ANSWER:</u>
The solution set for the inequality 7x < 7(x - 2) is null set 
<u>SOLUTION:</u>
Given, inequality expression is 7x < 7 × (x – 2)
We have to give the solution set for above inequality expression in the interval notation form.
Now, let us solve the inequality expression for x.
Then, 7x < 7 × (x – 2)
7x < 7 × x – 2 × 7
7x < 7x – 14
7x – (7x – 14) < 0
7x – 7x + 14 < 0
0 + 14 < 0
14 < 0
Which is false, so there exists no solution for x which can satisfy the given equation.
So, the interval solution for given inequality will be null set
Hence, the solution set is 
I would don't really have the answer to this question maybe try rewording it
Answer:
g(x) = 
Step-by-step explanation:
f(x) = 3x + 5
f[g(x)] = 3[g(x)] + 5
⇒ 3[g(x)] + 5 = x + 4
⇒ 3[g(x)] = x + 4 - 5
⇒ 3[g(x)] = x - 1
⇒ g(x) = 
Answer:
B. (0,0)
Step-by-step explanation:
The y-intercept of the equation f(x) = 1/2x lies on the y-axis.
This means we need to set x = 0 and solve for y
1/2(0) = 0
Therefore, (0,0) is the y-intercept of this equation.
