Answer:
1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
Step-by-step explanation:
Ikr the bots are annoying.
Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]
Slope intercept form is written as: [tex]y=mx+b[/tex]
We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
1) Points given are (1,6) and (-2,8)
Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]
You can choose either of the two points to put into the formula. I just chose (1,6)
Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]
2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.
[tex]6=-\frac{2}{3} (1)+b[/tex]
[tex]6=-\frac{2}{3} +b[/tex]
[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]
[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]
Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
$39.98 selling price and tax rate 4.5%
Answer:
Step-by-step explanation:
The marked price is 39.98
The tax is 4.5%
That means that the tax is added on to the marked price to get the selling price.
One way to do is is to multiply by the tax factor.
The tax factor is 1 + 4.5/100 = 1.045
So the Selling price = 39.98 * 1.045
Selling price = 41.78 rounded to 2 decimal places.
The more standard way of doing this is to multiply the tax by the marked price and add that on to the marked price to get the selling price.
39.98 * 4.5/100 = 1.7991
39.98
1.7991 Add
41.7791
The difference comes in where you do the rounding. The second way to do this has no rounding. If you convert this to money, the answer will be 41.78, just as the first way's answer.
Multiply. Enter your answer in scientific notation.

30 fortyths into a decimal
Answer:
0.3
Step-by-step explanation:
Percent means 'per 100'. So, 30% means 30 per 100 or simply 30/100. If you divide 30 by 100, you get 0.3 (a decimal number). So, to convert from percent to decimal, simply divide by 100 and remove the '%' sign. There is a easy way to convert from percent to decimal: Just move the decimal point 2 places to the left.
Hope this helps :)

Step-by-step explanation:
9. ⅔×½=⅓ ( the 2 in the numerator cancel out with the 2 in the denominator).
12. ⅓×¼=¹/(3×4) = ¹/12. (multiply the denominators 3 & 4)
15. ⁴/10×⅖= 4/25. (divide 2 in the numerator with the 10 in the denominator which gives the quoetiont 5) .

The sum of 24 and x is - 20.
Answer:
x+24 = -20
this is the equation form
Answer:
24 + x = -20
Step-by-step explanation:
"The sum" is simple addition, so stating that the "sum of 24 and x" is the same as :
24 + x
Seeing as they equal -20:
24 + x = -20

Answer:
The inequality is x/5 < 20, and 100 is in the box.
Step-by-step explanation:
x = the amount she spends in June.
So, since she spends an equal amount five times, the amount she spends each time is x/5.
She wants this to be less than 20.
So, x/5 < 20.
Solving for x by multiplying both sides of the equation by yields
x < 5 * 20
x < 100, so that 100 goes into the box.

Step-by-step explanation:
Allison and Lindsey each measured their bedrooms for new carpeting. They found
that both rooms were square, with the length of Lindsey's room 3 feet longer than
Allison's. If Lindsey needed 225 square feet of carpeting, how many square feet of
carpeting did Allison need?
Answer:
Step-by-step explanation:
Let's assume that the length of a side of Allison's room as x
So, Lindsey's room = x + 3
If Lindsey's room needs 225 sq. feet of carpeting, then x + 3 = [tex]\sqrt{225}[/tex]
So, x + 3 = 15
Therefore, x = 15 - 3 = 12 ( So, Allison's room has a side of length 12)
Therefore, the carpeting needed = 12 × 12 = 12² = 144 sq. feet
