(5,4) (3,7) find the equation for A+b=C

sp2606 [1]

Answer:

Step-by-step explanation:

Slope of line through (5,4) and (3,7) = (7-4)/(3-5) = -1.5

Point-slope equation of line:

y-4 = -1.5(x-5)

Convert equation to standard form:

y-4 = -1.5x + 7.5

1.5x + y = 11.5

Solve the following inequality: |x – 4|> 6

Hoochie [10]

Answer:

x>10 or x< -2

Step-by-step explanation:

There are two solutions, one positive and one negative, remembering to flip the inequality for the negative

x-4 >6 or x-4 < -6

Add 4 to each side

x-4+4 > 6+4 or x-4+4 < -6+4

x>10 or x< -2

Are the fractions 3/9, 3/10, 3/11, and 3/12 in order from least to greatest

Cerrena [4.2K]

Answer:

The fractions $\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$ are not in order from least to greatest.

Step-by-step explanation:

Given order of fractions from least to greatest:

$\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$

To check if the fractions are in correct order.

Solution:

The fractions given have same numerators but different denominators.

For fractions the higher the denominator the lower is the value of that fraction.

Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is $\frac{3}{12}$ and the greatest value fraction will be the fraction with the least denominator which is $\frac{3}{9}$

So, the order of the fractions from least to greatest is not correct. Instead the order is from greatest to least.

The correct order from least to greatest should be:

$\frac{3}{12},\frac{3}{11},\frac{3}{10},\frac{3}{9}$ .

Karen bought 6 CDs that were each the same price. Including sales tax, she paid a total of $71.40. Each CD had a tax of $1.10. W

sleet_krkn [62]

Answer:

$10.80

Step-by-step explanation:

Given:

Total number of CDs = 6

Cost price (including tax) = $71.40

Each CD had a tax of $1.10

To find the price of each CD before tax Let's first find the price of each CD after tax.

Price after tax = $\frac{71.40}{6} = 11.90$

Price of each CD after tax = $11.90

Since each CD had a tax of $1.10, price of each CD before tax would be : $11.90 - $1.10 = $10.80

Therefore price of each CD before tax is $10.80
