Resistance = voltage/currant
Resistance= 80/40 = 2
Resistance = 2 (Ohms)
Answer:
Hey there!
a. 2x+5=30
b. 1/3x-8=x+1
c. 3=21/(x+5)
d. 3x-5=46
For the picture
a. y=7x+60
b. y=5x+120
c. 7x+60=5x+120
Let me know if this helps :)
Answer:
![y=30x+475](https://tex.z-dn.net/?f=y%3D30x%2B475)
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
b is the y-intercept or initial value
Let
y ----> total weekly pay
x ---> is the number of computers sold in a week
In this problem we have
![m=\$30\ per\ computer\ sold](https://tex.z-dn.net/?f=m%3D%5C%2430%5C%20per%5C%20computer%5C%20sold)
![b=\$475](https://tex.z-dn.net/?f=b%3D%5C%24475)
substitute
![y=30x+475](https://tex.z-dn.net/?f=y%3D30x%2B475)
Answer:
The y-intercept is ![b=0](https://tex.z-dn.net/?f=b%3D0)
The y-intercept represents the initial quantity of gas in the canister which is zero.
Step-by-step explanation:
The y-intercept is where the graph of the straight line touches the y-axis.
From the graph, the y-intercept is the origin (0,0).
Recall that the slope intercept form of a straight line is
, where
is the y-intercept in this case.
Since the graph represents the amount of gasoline in a canister after Joshua begins to fill it at the gas station pump, the y-intercept means the initial gallons of gas in the canister is zero.
The answer is 84 degrees you just subtract 180-90
