Answer:
so x=3
Step-by-step explanation:
f(x) = 2
We want to find the x value when y =2
Going across where y = 2
Then go down to find the x value x=3 when y = 2
f(3) =2
so x=3
The numbers get smaller in division and larger in multiplying
Answer:
Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph
is below
![y = - \frac {5}{2} x + 2](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B5%7D%7B2%7D%20x%20%2B%202)
Step-by-step explanation:
Slope of the equation
is ![m_1 = \frac{2}{5}](https://tex.z-dn.net/?f=m_1%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as
![m_2 = - \frac {1}{m_1} = - \frac {5}{2}](https://tex.z-dn.net/?f=m_2%20%3D%20-%20%5Cfrac%20%7B1%7D%7Bm_1%7D%20%20%3D%20-%20%5Cfrac%20%7B5%7D%7B2%7D)
Equation of line in point slope form is given as
![y-y_1=m_2(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm_2%28x-x_1%29)
Here (x1, y1) = (4, -8)
![y+8 = - \frac{5}{2} (x-4)](https://tex.z-dn.net/?f=y%2B8%20%3D%20-%20%5Cfrac%7B5%7D%7B2%7D%20%28x-4%29)
Simplifying it further
![y = - \frac {5}{2} x + \frac {5}{2} 4 - 8](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B5%7D%7B2%7D%20x%20%2B%20%5Cfrac%20%7B5%7D%7B2%7D%204%20-%208)
![y = - \frac {5}{2} x + 2](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%20%7B5%7D%7B2%7D%20x%20%2B%202)
Answer:
7
Step-by-step explanation:
each cup is 1/3 so divide 2 1/3 by 1/3 to get 7 cups
hope this helps
