Answer:
B. y=-0.5x + 1
Step-by-step explanation:
first look at the slope: slop = rise over run. for every 2 units right, the point goes 1 unit down. so the slope if -1/2 or -0.5
next look at the y-intercept. the y-intercept of this graph is 1
plug these into the equation y= mx + b to get y = -0.5x + 1
Answer:
23
Step-by-step explanation:
So what we want to do first is expand the left side
5(x+4)
Use Foil
5x + 20
Now lets put everything together
5x + 20 = 7x - 26
Bring the x's to one side
5x + 20 (-5x) = 7x - 26 (-5x)
20 = 2x - 26
Move the constants to one side
20 (+26) = 2x - 26 (+26)
46 = 2x
Now divide by 2
x = 23
Answer:
Step-by-step explanation:
The rules of exponents say ...
![\displaystyle\sqrt[a]{b^c}=b^{\frac{c}{a}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5Ba%5D%7Bb%5Ec%7D%3Db%5E%7B%5Cfrac%7Bc%7D%7Ba%7D%7D)
Here, you have a=3, b=8, c=x, so the alternate form is ...
