Below are the steps for solving an inequality. What is the final step required to solve the inequality?
5x+7>3x−9
2x+7>−9
2x>−16
Multiply by 2 and reverse the inequality symbol.
Divide by 2 and reverse the inequality symbol.
Multiply by 2 and do not reverse the inequality symbol.
Divide by 2 and do not reverse the inequality symbol.
Answer:
Divide by 2 and do not reverse the inequality symbol.
Step-by-step explanation:
2x>−16
dividing by 2 from both sides
x>-8
(you only have to reverse the inequality symbol when you multiply or divide by a negative number but 2 isn't a negative number)
the first and the third choices are also excluded because multiplying by 2 won't solve the inequality
it would be either
4x<−32
or
4x>−32
and the first one is wrong because as we know that multiplying by a positive number doesn't reverse the inequality symbol

Answer: 226.19467 = final answer of 226.2
Step-by-step explanation:
16 = s/2 *
Solve the equation (1 point). Show the inverse operation and the appropriate property of equality (2 points). Check your answer by substituting it for the variable, into the equation, to prove the solution makes the equation true (2 points). 5 total possible points.

Write the equation of the given graph.
Answer:
y = 2x -3
Step-by-step explanation:
Answer:
y = 2x - 3
Step-by-step explanation:
In order to get the slope, you do rise/run. So, to get from one point to another, you would need to move 2 units up, and 1 to the right, which is the same as 2x.
Now to find the y-intercept, all you need to do is check which point of the line intersects in the y-axis. That would be -3.

How could you use repeated addition to show ratios equivalent to 1:3 on a graph?
Answer:
Step-by-step explanation:
Use a table with x and y, every time x increases, it increases by 3, and every time y increases, it increases by 1
Repeated addition:
x y
0 + 3 0 + 1
3 + 3 1 +1
6 + 3 2 + 1
9 + 3 3 + 1
12 + 3 4 + 1
15 +3 5 + 1
Before they graduate from Great Lakes High School, all 12th grade students fill out a survey about their future college plans. Are you attending an in-state college after high school graduation? Will you begin college during the summer semester? The same group of students are asked to answer yes or no to both questions. The students’ responses were recorded on the table below. Attending an In-State College Not Attending an In-State College Begin Summer Semester 178 21 Won't Begin Summer Semester 301 162 Determine the probability that a student will begin college during the summer semester and attend an in-state college. Determine the probability that a student will begin college during the summer semester given that he is attending an in-state college.
Answer:
479
Step-by-step explanation:
The requried probability that a student will begin college during the summer semester given that he is attending an in-state college is 0.894.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
To determine the probability that a student will begin college during the summer semester and attend an in-state college, we need to find the number of students who satisfy both conditions and divide it by the total number of students. From the table, we see that 178 students are attending an in-state college and beginning during the summer semester, so the probability is:
P(Attending in-state and beginning summer) = 178/662 ≈ 0.269
To determine the probability that a student will begin college during the summer semester given that he is attending an in-state college, we need to find the number of students who are attending in-state colleges and beginning during the summer semester and divide it by the number of students who are attending in-state college. From the table, we see that 178 students are attending in-state college beginning during the summer semester, and 178 + 21 = 199 students are attending in-state college. So the probability is:
P(Beginning summer | Attending in-state) = 178/199 ≈ 0.894

What is the slope-intercept equation for this line
(y= mx + b)?
Answer:
y = -6x + 2
Step-by-step explanation:
To find the slope, you do rise/run. To get to one point from another, you move one unit to the right, and six units down.
Now to find the y-intercept, you need to identify the point that meets in the y-axis. That would be 2.
Hope this helps!
Answer: y = -6x +2
Step-by-step explanation:
rise/run is 6/1 so slope = 6
y intercept of 2

solve the equation
0.2(d-6)=0.3d+5-3+0.1d for d
Answer:
d= -16
Step-by-step explanation:
To answer this question you'll have to first simplify the equation to
0.2d+-1.2=0.3d+5-3+0.1d
then combining like terms you get
0.2d-1.2=(0.3d+0.1d)+(5+-3)
0.2d-1.2=0.4d+2
then subtract 0.4d from both sides leaving you with
-0.2d-1.2=2
then add 1.2 to both sides
-0.2d=3.2
after you divide both sides by -0.2
leaving you with the answer
D= -16
Answer:
D = -16
