Answer:
Second step: 2/2 does not give you 2.
It would be 2x + 1 - 4 = 3x - 3
Since he mess up on the second step, the following steps are also messed up
Answer:
According to the passage, whales weight 300,000 pounds on average. Narwhales weigh 2,000 pounds on average.
Step-by-step explanation:
Since the question is extremely vague, I'll just answer what's the weight of whales and the weight of narwhals.
According to the paragraph, blue whales weigh 3×
pounds.
This is what we call scientific notation. You could solve it normally, or you could use a faster method.
Scientific notation states that the first number that you see, the three, is the first part of the answer. The exponent on the number of zero's that there is.
That means that the answer to 3×
you get 300,000.
Let's do the same thing to Narwhales.
2×
is 2,000.
The median or middle would be 1.5, since in the middle are 2 numbers 1, and 2. You would add them together and divide them by 2 and get 1.5
Answer: y= 2x +4
Step-by-step explanation:
1. To be able to write the equation of the line, you want to be able to find the slope first. To do so, rearrange the given equation x+2y=2 into slope-intercept form, which is y=mx+b
First subtract x from both side, which will give us 2y=2-x. Rearrange this to get 2y= -x+2. Then, divide both sides by 2. This will give us y= -1/2x+1
2. Now that you have the equation, look for the slope in the new equation; this will be the m value. In this case, the slope is -1/2. Since we are looking for a line that is perpendicular, we have to change the slope so that it is the opposite reciprocal. The opposite reciprocal of -1/2 is 2, so the slope of the equation we want to find is 2.
3. Next, all we have to do is plug the given ordered pair (-5, -6) and the slope that we found (m=2) into the point-slope equation, which is 
That will give us:
y+6 = 2(x+5)
4. Now, solve this equation.
y+6 = 2(x+5) --> distribute the 2 inside the parentheses
y+6 = 2x + 10 --> subtract 6 from both sides
y= 2x +4
