Well you will divide 27 by 12 because there are 12 months in a year to get 2.25 lbs per month, you go gurl, way to work out and loose weight:):) gope I helped
The answer would be A since in that case its a percentage and there can be multiple answers. In the other questions, there is a definitive answer for it.
Hope this helps :)
What you want to do for each of those is follow the formula, y-y[1]=m(x-x[1]). When I say y[1] and x[1], I mean the x and y values given. So the first one would be y-4=-3(x-(-1)). Then you solve for y by distributing the -3 to x and +1 (+1 because two negatives make a positive), making the equation
y-4=-3x-3. Then you subtract the 4. Answer #1. y=-3x-7.
#2.
y-1=1(x-4)
y-1=x-4
y=x-5
#3.
y-2=2(x-(-1))
y-2=2x+2
y=2x+4
Hope this helped you!
Given:
The function is:
![h(x)=x^2-3x+5](https://tex.z-dn.net/?f=h%28x%29%3Dx%5E2-3x%2B5)
To find:
The value of
.
Solution:
We have,
![h(x)=x^2-3x+5](https://tex.z-dn.net/?f=h%28x%29%3Dx%5E2-3x%2B5)
Putting
, we get
![h(2x+1)=(2x+1)^2-3(2x+1)+5](https://tex.z-dn.net/?f=h%282x%2B1%29%3D%282x%2B1%29%5E2-3%282x%2B1%29%2B5)
![h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5](https://tex.z-dn.net/?f=h%282x%2B1%29%3D%282x%29%5E2%2B2%282x%29%281%29%2B%281%29%5E2-3%282x%29-3%281%29%2B5)
![h(2x+1)=4x^2+4x+1-6x-3+5](https://tex.z-dn.net/?f=h%282x%2B1%29%3D4x%5E2%2B4x%2B1-6x-3%2B5)
On combining like terms, we get
![h(2x+1)=4x^2+(4x-6x)+(1-3+5)](https://tex.z-dn.net/?f=h%282x%2B1%29%3D4x%5E2%2B%284x-6x%29%2B%281-3%2B5%29)
![h(2x+1)=4x^2-2x+3](https://tex.z-dn.net/?f=h%282x%2B1%29%3D4x%5E2-2x%2B3)
Therefore, the required function is
.

<u>Point-slope form</u>:-
![\sf{y-y_1=m(x-x_1)}](https://tex.z-dn.net/?f=%5Csf%7By-y_1%3Dm%28x-x_1%29%7D)
Substitute 1 for y₁, 2 for m, and 0 for x₁:-
So we conclude that Option B is correct.
<h3>Good luck.</h3>
