Set up a ratio:

12/5x-2 = 16/6x

Cross multiply:

12(6x) = 16(5x-2)

Use distributive property:

72x = 80x - 32

Subtract 80x from both sides:

-8x = - 32

Divide both sides by -8:

X = 4

PLEASE HELP ASAP
il63 [147K]

Step-by-step explanation:

The problem asks to find the values "b" and "c" in a way that

the solutions of the equation |x - b| = c are x= 1/2 and x= -1/3.

It means that "b" is the center of the segment [-\frac{1}{3} ,\frac{1}{2}].

This segment has the length \frac{1}{2} - ( - \frac{1}{3} = \frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}  Hence, the half of this length is \frac{5}{12}.

Therefore, the center of the segment is \frac{1}{2} - \frac{5}{12} = \frac{6}{12} - \frac{5}{12}  = \frac{1}{12}

Thus the value of "b" is found: it is b = \frac{1}{12}.

Then the value of "c" is  c =\frac{1}{2} - \frac{1}{12} = \frac{5}{12}.

The value of a plot of land is S18 000.00.
Brums [2.3K]

Answer:

$126

Step-by-step explanation:

The plot of land is worth $18,000 and the tax on the land is $0.70 per $100. You would divide 18000 by 100 which is 180. Then you would multiply 180*0.70 which is $126.

Can someone please help me
Assoli18 [71]
To move it 1 to the left, we make x into (x+1), so we have (x+1)². Conversely, if we wanted to move it to the right, we'd subtract 1 from x. Next, we have to vertically stretch by a factor of 3, meaning that we have to multiply the whole thing (at the current point) by 3, turning our equation into 3(x+1)². Lastly, we must reflect over the x axis, which is the line g(x)=0. If we want to reflect over g(x), we essentially multiply g(x) by -1, making -g(x)=3(x+1)². However, we want to solve for g(x), not -g(x), so we multiply both sides by -1 to end up with -3(x+1)²
