Answer:
2 dollars?
Step-by-step explanation:
8 divided by 4
In general, any equation like
(assuming
) is solved by
![x= \dfrac{b}{a}](https://tex.z-dn.net/?f=%20x%3D%20%5Cdfrac%7Bb%7D%7Ba%7D%20)
So, in your case, the solution is
![x = \dfrac{\frac{1}{5}}{\frac{3}{4}}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cdfrac%7B%5Cfrac%7B1%7D%7B5%7D%7D%7B%5Cfrac%7B3%7D%7B4%7D%7D%20)
Dividing by a fraction means to multiply by the inverse of that fraction:
![\dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Cfrac%7B1%7D%7B5%7D%7D%7B%5Cfrac%7B3%7D%7B4%7D%7D%20%3D%20%5Cdfrac%7B1%7D%7B5%7D%20%5Ccdot%20%5Cdfrac%7B4%7D%7B3%7D%20%3D%20%5Cdfrac%7B4%7D%7B15%7D%20)
Answer:
y = 7/8x + 1
Step-by-step explanation:
According to y = mx + b, whereas b is the y-intercept
so if b is positive, b has to be larger than 0
A non-proportional graph is a straight line that does not go through the origin so
The #1 and #4 are wrong because they are proportional
The #2 and #4 are wrong because they have negative y-intercept
Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations
