Answer:
idk
Step-by-step explanation:
So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).
So.
g(1.5)=8-3(1.5)
=8-4.5
=3.5
Then.
H(3.5)=2x+5
=2(3.5)+5
=7+5=12
Your final answer is 12.
Answer:
a. Yes
b. No
Step-by-step explanation:
To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.
1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:

1 is greater than or equal to 1, so (3,1) is a solution.
2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:

However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.
Yes, the equation given above is proportional. The variables y and x are directly proportional to each other. <span>Two variables are proportional if a change in one is always accompanied by a change in the other, and if the changes are always related by use of a constant multiplier.</span>
