PLEASE HELP I NEED HELP ASAP

Mathematics
1 answer:
Slav-nsk [51]2 years ago
5 0

Answer:

y=-x+15

Step-by-step explanation:

Slope-intercept form is written as y=mx+b where m is the slope and b is the y-intercept.

Any line perpendicular to a given line with slope m has a slope of -\frac{1}{m}. Therefore, the slope of a line perpendicular to y=x+12 is -\frac{1}{1}=-1.

We can now plug the coordinate it passes through into our slope-intercept form equation to solve for the y-intercept:

3=-1(12)+b,\\b=15

Therefore, the equation of the line that is perpendicular to y=x+12 and passes through the coordinates (12,3) is \fbox{$y=-x+15$}.

Shane started FFA with a pig that weighed 120 pounds. After six weeks her pig gained 30% in weight. what is the new weight of sh
grigory [225]
First, we must figure out how much weight the pig gained and then add that number to the pig’s initial weight.

To figure out how much weight the pig gained, we must find 30% of 120.

Because 30% = 0.3, 30% of 120 = 0.3 * 120 ( the word of indicates multiplication in mathematics).

0.3 * 120 = 36

Therefore, the pig gained 36 pounds.

To find the pig’s new weight, we must add 36 pounds to the pig’s original 120 pound weight.

36 + 120 = 156

Therefore, the new weight of Shane’s pig is 156 pounds.

Hope this helps!

Part C: Of the following choices, which equation is the best fit line for the data
KatRina [158]

Step-by-step explanation:

Part C: Of the following choices, which equation is the best fit line for the data

As we can see from the data, the population size are decreased year by year, so the slope of the line of best fit must be a negative number.

So we have: C and D left.

Let x = 0, year 2005, the population size is 296 around 320, hence, we choose D.

D f(x) = -34x + 320

Part D: What is the predicted population size for the year 2010? How does that compare to the real data? Round to the nearest million.

year 2010, x =5 so let substitute x =5 into  f(x) = -34x + 320

<=> f(x) = -34*5 + 320

= 150 mil

The result is smaller than the real data, (201-150 = 51 mil)

Part E: In what year is the population predicted to go extinct

the population predicted to go extinct when f(x)= 0

<=> -34x + 320 = 0

<=> x  ≈ 9.4

So after 10 years, the the population predicted to go extinct
