Which of the following is the inverse of F(x) = 2x + 3 ?
Explanation:
y=f(x)
y=2x+3
Switch the places of x and y:
x=2y+3
Solve for y:
2y=x−3
y=(x−3)/2
Thus inverse of f(x)= (x-3)/2

Solve for x.
Answer:
x = 9
Step-by-step explanation:
Theorem:
The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.
The angle measuring 12x + 14 is an exterior angle of the triangle.
The angles measuring 76 deg and 1 + 5x are its remote interior angles.
12x + 14 = 1 + 5x + 76
12x + 14 = 5x + 77
7x = 63
x = 9

А.For every $1 spent, you will receive 1.25 greeting cards.
B.For every $2 spent, you will receive 5 greeting cards.
С.For every $5 spent, you will receive 2 greeting cards.
D.For each additional greeting card you purchase, you will spend $0.40.
solve the inequality 3x+3>48
[tex]3x + 3 > 48[/tex]
Solving the Inequality is similar to solving the equation. We simply make x-term as the subject since we are solving for x.[tex]3x > 48 - 3 \\ 3x > 45 \\ x > \frac{45}{3} \Longrightarrow x > \frac{ \cancel{45}}{ \cancel{3}} \Longrightarrow x > \frac{15}{1} \\ x > 15[/tex]
Answer CheckBecause x must be greater than 15. We will substitute x = 16 in the Inequality.
[tex]3(16) + 3 > 48 \\ 48 + 3 > 48 \\ 51 > 48 \: \: \checkmark[/tex]
The Inequality is true when x > 15.

In a recent year, 33.8% of all registered doctors were female. If there were 54,300 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.
Answer:
160 650.88 ( rounds to 160 651)
Step-by-step explanation:
Let n be the total amount of registered doctors that year. Then:
0.338n=54300
n=54300/0.338= 160 650.88 ( rounds to 160 651)

if 0.4 < x > 45%, which of the following could be the value of x?
Answer:
0.41, 0.42, 0.43, 0.44
Step-by-step explanation:
Convert the percent to a decimal:
0.4 < x > 0.45
Now, the variable x has to be any number between 0.4 and 0.45, which include:
0.41, 0.42, 0.43, 0.44
Answer:
5/10
Step-by-step explanation:
So you can split this into two inequalities, x > 0.4 and x > 45%. First you can change the second one to decimal form, so x > 0.45. Because 0.45 is already greater than 0.4, you can just ignore the second inequality. (If x is greater than 0.45 it will automatically be greater than 0.4 so it doesn't matter).
From the 4 options you gave, 5/10, or 0.5, is the only one that is greater than 0.45.
Erin and her friends are taking a road trip. She has agreed to drive between hours 3 and 6 of the trip. If h represents the hours of the trip Erin will be driving, then h ≥ 3 and h≤ 6 represents her portion of the driving. While she is driving, her distance and time are modeled by the inequality d < 70h. What are the possible hours and distances Erin could be driving?
When graphing this scenario, let h be the horizontal variable and d be the vertical variable.
For the inequality h ≥ 3, the graph should be shaded
the boundary line.
For the inequality h ≤ 6, the graph should be shaded
the boundary line.
For the inequality d < 70h, the graph should be shaded
the boundary line.
One possible solution for Erin is .
Answer:
For the inequality h ≥ 3, the graph should be shaded
✔ to the right of
For the inequality h ≤ 6, the graph should be shaded
✔ to the left of
For the inequality d < 70h, the graph should be shaded
✔ below

[tex] - 2 \sqrt{7} [/tex]
Answer:
A. -2[tex]\sqrt{7}[/tex]
Step-by-step explanation:
3 - 5 = -2
The [tex]\sqrt{7}[/tex] is just like an x variable at this point because they are both the same. If it was [tex]\sqrt{7}[/tex] and [tex]\sqrt{14}[/tex] for example, then you wouldn't be able to subtract them so easily. Kinda like how you can't subtract 3x-5y because they're two different variables.

so if you put 14 in the boys bubble then do 30-14
Step-by-step explanation:
Answer: 0.5
a) boys: 14
girls : 16
b) the ways to randomly select a student is n(A) = 30C1 = 30
the ways to choose a girl is n(B) = 16C1 = 16
=> the probability to randomly select a student being a girl is
n(B)/n(A) = 16/30 ≈ 0.5
