Step-by-step explanation:
[tex]5x+8+3x+4=-40+4[/tex]
⇒ Subtract 4 from both sides:

[tex]5x+8+3x=-40[/tex]
⇒ Combine like terms:

- 67 minus what gives me 0
Answers
Answer:
-67
Step-by-step explanation:
-67 minus -67 = -67+67 (since two negatives make a positive) =0
Answer:
Step-by-step explanation:
For the math problem, "67 minus what equals 0?", we can make it into an algebra equation as follows:
67 - X = 0
Then, we solve for X. To solve for X, we first subtract 67 from both sides:
67 - 67 - X = 0 - 67
-X = -67
Next, you multiply each side by -1 to remove the minus from the X:
-X(-1) = -67(-1)
X = 67
Therefore, the answer to "67 minus what equals 0?" is 67 as illustrated below:
67 - 67 = 0

The 3 is the ones digit.
The 7 to the left of the 3 is the 10s digit.
The 7 (in bold) to the left of the other 7 is the hundreds digit.
1. Make all digits to the right of the hundreds digit 0.
4700
2. We need to find out if we end up with 4700 or 4800.
Since the digit just to the right of the hundreds digit is greater than 4 (it is the tens digit which is a 7), then the hundreds digit 7 must go up 1 to 8.
Answer: 4800

A function is a relation in which no two ordered pairs have the same first component and different second components.
We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)?
In this case, the answer is no. The input value of 1 goes with two output values, -1 and -5. The same goes with the input value of 2, which also goes with two output values: -2 and -4.
It only takes one input value to associate with more than one output value to be invalid as a function.
I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

So...
1/2 of 50 is 25.
-kiniwih426
Answer:
$50
Step-by-step explanation:
Solution:
Let the unknown number be x
50% × x = $25
50/100 × x = 25
x = 25×100/50
x = $50
Varification:
50% of $50 is $25
50/100 × 50 = 25
25 = 25
what is the multiplicative inverse of -3 1/2
A) 7/2
B) -2/7
C) 9
Answers
Answer:
B or -2/7 should be correct
Step-by-step explanation:
First, I would find out the improper fraction of -3 1/2
The improper fraction of -3 1/2 is -7/2
To find the multiplicative inverse, we will flip the numerator and the denominator.
Multiplicative inverse of -7/2 = 2/-7
2/-7 is a weird way to write a fraction, so to convert into a reasonable fraction, we will multiply both the numerator and denominator by -1.
2/-7 x -1/-1 = -2/7
Therefore, B should be your answer
Kind requests:
Please give me brainliest :)
B) -2/7
Explanation:
this is because, you start out by simplifying -3 1/2 to get -7/2 next you find the multiplicative inverse of which is -2/7
In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answers
Answer:
169,000 people
Step-by-step explanation:
increase from 2010-2015:
168000/100 = 1680 = 1%
1680 x 7 = 11,760 people
population at 2015 = 168000+11760 = 179,760
decrease from 2015-2020:
179760/100 = 1797.6 = 1%
1797.6 x 6 = 10,785.6 people
population at 2020 = 179760-10787.6 = 168,974.4 people
rounded to the nearest 100 = 169,000 people

Answer:
y = -3/4(x -2)
Step-by-step explanation:
You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...
m = rise/run = -3/4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m = -3/4 and (h, k) = (2, 0), the equation is ...
y = -3/4(x -2)
_____
Additional comments
If you use the distributive property to eliminate parentheses, the equation becomes ...
y = -3/4x +3/2
The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...
m = rise/run = 4/3
The slope of the perpendicular (red) line is the opposite reciprocal of this:
-1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph
