2/9 - 7/12

First, multiply to find a common denominator. Multiply both pieces of the left fraction by 12, and both pieces of the right fraction by 9.

24/108 - 63/108 = -39/108 = -13/36

a= -13
b= 36

Write the equations after translating the graph of y = | 1/2x−2|+3, one unit to the right
AveGali [126]

y=|\dfrac{1}{2}x-2|+3

Since we are translating this graph one unit to the right, replace x with (x-1)

Note: If you are translating a graph to the left by k units, replace x with (x+k), and if by the right, replace x with (x-k)

y=|\dfrac{1}{2}(x-1)-2|+3

After simplifying, we now have the following equation:

=|\dfrac{1}{2}x-\dfrac{5}{2}|+3

This is the new equation. Let me know if you need any clarifications, thanks!

the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an eq
Oksanka [162]
So, let's first focus on the first year:

the population then would be: 23000* (100+2)%

100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.

So it will be 23000*1.02

After two years it will be 23000*1.02*1.02, and so on

so after x years it will be:

y=23000*1.02^{z}

John used 1 3/4 kg of salt to melt on his sidewalk. He then used another 3 4/5 kg on the driveway. If he originally bought 10 kg
Natali [406]

Answer:

he have left 4.45 kg

Step-by-step explanation:

The computation of he have left is as follows:

= Total salt purchase - salt used on his sidewalk - sales used on the driveway

= 10 - 1 \frac{3}{4} - 3 \frac{4}{5}\\\\= 10 - \frac{7}{4} - \frac{19}{5}\\\\= \frac{200 - 35 -76 }{20}  \\\\= \frac{89}{20}

= 4.45 kg

Hence, he have left 4.45 kg
