First Step: We are simplifying the left-hand side by multiplying the coefficient to the (2x + 9)
Second Step: We subtract 30x from both sides to get all the x's on one side
Third Step: We add (or subtract in this case) like terms, which in this case you're taking 30x <u>from</u> 150x
Fourth Step: You subtract the remaining constant (675) from both sides to isolate your variable (x) on one side
Fifth and Final Step: You divide both sides by x's coefficient, 120, to get the value of x by its self
Answer:
(x*2)+3 = y
Step-by-step explanation:
It multiplies x by 2, then adds 3.
Domain is f(x) > 0
range is x is any real number
First, you know that the slope will be the same (3/2).
Plug in the points 0 for x and 7 for y in order to find b.
7=3/2*0+b
b=7
Then put the new slope and y-intercept into the equation:
y=3/2x+7
Answer:
57% of 11 is 6.27
Step-by-step explanation:
All we have to do is convert the percent to a decimal, then multiply the decimal by 11.
0.57 × 11 = 6.27
