-28=-2x
Divide by negative 2
Your answer: x=14
The subtraction of the given expression will be (x²-9x +1).
<h3>What is subtraction?</h3>
The method of removing or deleting anything from the given set will be defined as subtraction. It is represented by the negative sign '-'.
The subtraction will be calculated as:-
E = (–3x² + 7 – 2x) – (6 + 7x – 4x²)
Arrange the terms in the above expression.
E = ( -3x²+4x²-2x-7x-6+7)
E = ( x² - 9x + 1 )
Therefore the subtraction of the given expression will be (x²-9x +1).

1.25mm x 50 = 62.5 mm Now lets change mm to meters. There are 1000 millimeters in a meter and we are only talking about 62.5 so we are not even at a single meter. Answers B and C can be eliminated.
meter decimeter centimeter millimeter (each one is ten times more or less than the previous one depending on where you start.
Since we are changing mm to m, we will get fewer. Why - try grouping any small things like 14 days - you get 2 weeks. 72 hours - you get 3 days. Notice that the number gets lower. 14---->2 and 72------->3
So we can expect our number to get smaller. The beauty of the metric system it that is based on 10 so it involves moving decimals and adding or subtracting zeros if needed.
meter dm cm mm
62.5
notice that it would take 3 "jumps" to the left to get it under the word meter. That means our decimal has to move 3 jumps to the left too. In order to do that we need to add a zero in front of the 6 in 62.5
<u>Correct answer is 0.0625 </u> which is none of the answers above - Notice that the decimal is 3 places left from where it was before (62.5).
Answer:
y=2/3x+4
Step-by-step explanation:
Looking at the line, we can see that from point (-3,2) to point (0,4) that the line moves 2 spaces upwards and 3 spaces to the right. Because of this, we know that the slope is 2/3 because we can simply put the rise (2) over the run (3).
Then, to find the y-intercept, we look to see where the line crosses the vertical axis, and in this case, that point is (0,4). So we now know the y-intercept is 4.
Finally, we put everything into slope-intercept form, and get y=2/3x+4
