Answer:
Step-by-step explanation:
We can combine the -7x and the -2x and the left side to get -9x and the 23 and 13 on the right side to get 36.
This gives us
-9x + 12 = 36
Subtacting 12 from both sides gives us
-9x = 24
dividing by -9 gives us
x = - 8/3
Answer:
2x-5=y
I'm not sure how your graphing tool works so I'll give you five or so coordinates
(-1,-7)
(1,-3)
(0,-5)
(2,-1)
(-2,-9)
Step-by-step explanation:
You first need to write an equation that you can graph
Knowing that the slope is two we can write the following equation
2x+b=y
We also know that when x=1 y=-3
This gives us 2*1+b=-3
which means that 2+b=-3
subtract 2 from both sides to figure out the b=-3
This means that the line you have to graph is 2x-5=y
Answer:
2.75
Step-by-step explanation:
let x be the number.
0.75 + 2 = x
2.75 = x
Answer: 5500cm.
Step-by-step explanation:
A revolution corresponds to circumference of the bicycle wheel.
The radius of the circle = 70/2 since two radii makes a diameter.
Therefore r = 35cm
Circumference of a circle = 2πr or πd where π = 3.142 or 22/7
We now have = 2 x 22/7 x 35
Therefore 0ne revolution = 220cm.
Therefore, the distance traveled by making 25 revolution
= 220 x 25
= 22000/4
= 5500cm.
Answer:
The domain is all real numbers except x=3
Step-by-step explanation:
Assuming you mean
f(x) = 1/(x-3)
The domain is all numbers that x can take
This function is define except when the denominator goes to zero
x-3 cannot be zero
x cannot be 3
The domain is all real numbers except x=3
