Answer:
g(x) = 2x + 13
Step-by-step explanation:
To shift a function f(x) to the left, we add the unit h inside the function argument.
That is g(x) = f(x + h)
To shift a function f(x) to the right, we subtract the unit h inside the function argument.
That is g(x) = f(x - h)
Now, to shift f(x) = 2x - 1 to the left, we add the unit 7 inside the function f(x + 7) to have
g(x) = 2(x + 7) - 1
= 2x + 14 - 1
= 2x + 13
15.25 divided by 100= 0.1525 times 15 = 2.2875 then round to $2.29 (2.29 is the tip) 2.29 + 15.25 = $17.54 would be the total cost!
First I chose two points on the line that fall on 2 intervals or 2 lines. Then if found the slope of the two points. Using the slope and one of the points I pugged the numbers into an equation to solve for b. Once I found b I wrote an equation using b and the slope.
y=-2/3+300
steps:
(250,200)(300,100)
100-200/300-150
-100/150 or -2/3
100=-2/3(300)+b
100=-200+b
300=b
y=-2/3b+300
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
Answer:
M = 108
a = 72
e = 108
Step-by-step explanation:
72 and m are a linear pair so they add to 180. 180-72 = 108
72 and are vertical angles which means they are equal. a=72
e and 72 are linear pair and and M are vertical so e =108
