Answer:
x= -2
Step-by-step explanation:
7x−11+11=3x−19+11=
7x-3x=3x−8-3x=
x= -2
Converting decimals:
Write down the decimal divided by 1, like this: decimal 1.
Multiply both top and bottom by 10 for every number after the decimal point. ...
Simplify (or reduce) the fraction.
They both are similar because you can divide by one? not sure on this part.
Answer:
65000
Step-by-step explanation:
(rounding to nearest thousands)
2014- 13000 sold
2015- 13000 more than 2014, so 26000
2016- same as 2016, 26000
just add them up-
13000+26000+26000= 65000
Answer:
a) one solution, x=3
b) see below
Step-by-step explanation:
2x+3=4x-3
2x=6
x can only be=3
Answer:
sqrt(1/2x+6) = h^-1 (x)
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y = 2x^2 -12
Exchange x and y
x = 2y^2 -12
Solve of y
Add 12 to each side
x+12 = 2y^2
Divide by 2
(x+12) /2 = 2y^2/2
(x+12)/2 =y^2
1/2 x+6 = y^2
Take the square root of each side
sqrt(1/2x+6) = sqrt(y^2)
sqrt(1/2x+6) = y
This is the inverse
