Determining Equivalent Expressions i'm confused on everything about it so if someone could clear it up for me. I will mark Brainliest
Answer:
Equivalent expressions
Step-by-step explanation:
Example
Lets start with numbers
1 + 2 = 3
The expression 1 + 2 is equivalent to 3
They have the same value
Now with algebras
2(x + 3) is equivalent i.e also equals to 2x + 6
3(x + 1) - 23 is equivalent to the following expressions:-
3x + 3 - 23
& 3x - 20
In conclusion equivalent expressions are different expressions that have the same values.
Use the numbers -2, -1/3,4, and -3/2. (Using only TWO of the numbers ,write a multiplication expression with a product greater than 2.) the symbols you can use is . ( ) -2 -1/3 4 -3/2. Please help :(
Answer:
-2 and -3/2
Step-by-step explanation:
-2 x -3/2 = 6/2 {negative x negative = positive}
6/2=3 which is >2
What is the minimum value of f(x) in the graph below?
Answer:
(2,-4)
Step-by-step explanation:
The minimum value is the lowest point on the graph.
Answer:
minimum value = - 4
Step-by-step explanation:
The minimum value is the value of y at the minimum vertex.
The vertex is at (2, - 4 ) with y = - 4
Thus minimum value is y = - 4

PLEASE HELP!!!!!
Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Answer:
Yes because of the Side-Angle Side postulate
Step-by-step explanation:
It is given that line BC is congruent to line BC
It is given that line AC is congruent to line EC
We now that angle DCE is congruent to angle ACB because they are vertical angles
I'm sorry if this is not the right explanation, but I do believe my answer is correct
Answer:
I believe that there would not be enough information because according to the SAS theorem (side, angle, side) you would need angle measure along with segment lengths to prove congruence, and the stated information does not contain an angle measure.
2x + 22 = 4(x + 3)
Please help me
Answer: x=5
Step-by-step explanation:
2x+22=4(x+3)
First distribute
2x+22=4x+12
Now intractable 2x from both sides
22=2x+12
Now subtract 12 from both sides
10=2x
Now divide by 2 to get x alone
5=x
So
x=5
Answer:
The answer is x = 5, see comments for explanation.

Find the value of angle “A” and angle “B”. WILL MARK BRAINLIEST
Answer:
157 for A and B
Step-by-step explanation:
180-23=157
Answer:
A) 157
B) 157
Step-by-step explanation:
A is 157 because A+23˚ makes a straight line or a 180˚ angle. If you subtract the 23˚ from 180˚ you should be able to find A.
B is the same because the angles A and B are vertical from each other, which means that they will have the same measurement. or you can use the same process as A.

Question 1
Solve for j:
Answer:
-300=j
Step-by-step explanation:
Lets set it up so we can cross multiply.
-60/1=j/-5
-300=j
Hope this helps :3
Answer:
j=300
Step-by-step explanation:
first you move the negative sign to the left so you will get
-60 = -
after multiply both sides 5 so you will get
-60 *5 =-j
after simplify to -60 * 5 to 300 so you will get
-300 = -j
then multiply both sides by -1
then switch the sides and that's how you get your answer .

If 3 cars have traveled a total of 180,000 miles and the distance traveled by each car differs by at least 1 mile from the distance traveled by either of the other 2 cars,what is the minimum possible number of miles traveled by the car with the most mileage
Answer:
60001 miles
Step-by-step explanation:
Given
[tex]Total\ Distance = 180000[/tex]
Let the cars be: [tex]Car\ A, Car\ B\ and\ Car\ C[/tex]
Assume that Car A has the minimum mileage of x.
[tex]Car\ A = x[/tex]
The other cars would be:
[tex]Car\ B = x + 1[/tex]
[tex]Car\ C = x + 2[/tex]
This implies that Car C has the highest mileage
Required
Determine the possible minimum number of miles
Since the total distance is 180000, then:
[tex]Car\ A + Car\ B + Car\ C = 180000[/tex]
Substitute values for Car A, B and C
[tex]x + x + 1 + x + 2 = 180000[/tex]
Collect Like Terms
[tex]x + x + x = 180000-1-2[/tex]
[tex]3x = 179997[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{179997}{3}[/tex]
[tex]x = \frac{179997}{3}[/tex]
[tex]x = 59999[/tex]
The car with the most mileage is Car C
So:
[tex]Car\ C = x + 2[/tex]
Substitute 59999 for x in [tex]Car\ C = x + 2[/tex]
[tex]Car\ C = 59999 + 2[/tex]
[tex]Car\ C = 60001[/tex]
The minimum distance travelled by Car C is 60001 miles
The graph below represents the distribution of scores on a placement test for students at Central High School. Select the statement that is true about the distribution of scores.
Placement Test Results
a.
The mode is the greater than the median.
c.
The mode is less than the median.
b.
There are two medians
d.
The median and mode are the same.
Please select the best answer from the choices provided
Answer: Choice A) The mode is greater than the median
Mode = 95, median = 90
========================================================
Explanation:
The mode is the most frequent value. In this case, the mode is 95. All we do is look for the highest bar, and then record the x value connected with it. The higher the bar, the more frequent the value.
------------------------
The median will take a bit more work, but it's not too bad.
First add up the heights of every bar shown:
2+3+4+6+7+10+5 = 37
So there are 37 scores. The median will be in the very exact middle. Divide 37 over 2 to get 37/2 = 18.5
Erase off the 0.5 and we can say that 18 values are below the median, and 18 values are above the median. So we have 18+1+18 = 37 values total.
The median will be in slot 18+1 = 19.
From here, we add up the bar heights (starting on the left and working toward the right). We're trying to see when we reach 19 or higher, since the median is in that 19th slot.
Add the first two bar heights: 2+3 = 5. That value is not 19 or larger. Add the first three bar heights: 2+3+4 = 9. Still not 19 or largerFirst four bar heights: 2+3+4+6 = 15. We're getting closer, but still no.First five bars: 2+3+4+6+7 = 22. We've crossed over 19. The median must be 90 because that x value is tied to the fifth bar.------------------------
To summarize:
mode = 95median = 90The mode is larger than the median.
This is why choice A is the answer.
Answer:
A- The mode is the greater than the median
