Answer:
4.5x - y = -1.5
Step-by-step explanation:
y - total
x - minutes
finding the slope intercept form is way easier
slope intercept form: y = 4.5x + 1.5
now, just put it into standard form:
Ax + By = C
4.5x - y = -1.5
remember that x in standard form can't be negative
Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1
the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2
minus 2
y=-x
answer is y=-x
Hello!
We are given the weight of Mia's dog and told to find the weight of Lettie's dog based on the known relationship. Using these given values, we can create the following equation (let "w" represent the total weight of Lettie's dog):
w = 32.6(3.8)
Simplify the right side of the equation:
w = 123.88
We have now proven that Lettie's dog weighs 123.88 lbs.
I hope this helps!

Answer: Option B.
![b=\frac{5}{4}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
![a = kb](https://tex.z-dn.net/?f=a%20%3D%20kb)
We know that when a = 28 then b = 7. So
![28 = k * 7](https://tex.z-dn.net/?f=28%20%3D%20k%20%2A%207)
![k=\frac{28}{7}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B28%7D%7B7%7D)
![k=4](https://tex.z-dn.net/?f=k%3D4)
Therefore the equation of proportionality is:
![a=4b](https://tex.z-dn.net/?f=a%3D4b)
So when
then:
![5=4b\\\\b=\frac{5}{4}](https://tex.z-dn.net/?f=5%3D4b%5C%5C%5C%5Cb%3D%5Cfrac%7B5%7D%7B4%7D)
