Lets begin with our y=mx+b, our constant(b) is 800 that she earns as a salary, our x represents the amount she sells, m then represents the commission which is 8.25% so converting that to a decimal and replacing it as m gets us y = 0.0825x+800. Replace $4500 for x and we have y=0.0825(4500)+800 solve and we get $1171.25

There are four nickels, three dimes, and three quarters in your pocket. You randomly pick three coins and place them on a counte
kupik [55]

Total coins = 10 ( 4 + 3 + 3 = 10).

The probability of picking a nickel first = 4/10 = 2/5 ( 4 nickels out of 10 total).

The probability of picking a dime second = 3/9 = 1/3 ( 3 dimes out of 9 coins left).

The probability of picking the third coin as a quarter = 3/8 ( 3 quarters out of 8 coins left).

The probability of picking all three in that order = 2/5 x 1/3 x 3/8 = 1/20

If the battery was used for 11 hours, then the value of x we use is 11
Subtitute x with 11 in the equation
y = 100 - 8.9x
y = 100 - 8.9(11)
y = 100 - 97.9
y = 2.1
The remaining power is 2.1%
the answer is option b

Which statement is true about the line represented on the equation y + 7 = -3 (x - 2/9) ?
Zarrin [17]

<u>ANSWER</u>

The point (\frac{2}{9},-7) lies on the straight line y+7=-3(x-\frac{2}{9})

<u>EXPLANATION</u>

The given line is y+7=-3(x-\frac{2}{9}). It can be observed that the given straight line is in the point-slope form.

We can rewrite the equation in the point-slope form to obtain,


y--7=-3(x-\frac{2}{9}).


When we compare this to the general point-slope form, which given by the formula;

y-y_1=m(x-x_1),

We can observe that,

x_1=\frac{2}{9} and y_1=-7.


Hence the point, (x_1,y_1)=(\frac{2}{9},-7) lies on y+7=-3(x-\frac{2}{9})
