Answer:

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

the correct answer is 12k-8

Step-by-step explanation:

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

Correcting the error:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8

So, the correct answer is 12k-8

xxMikexx [17]

Answer:

$1850

Step-by-step explanation:

The annual cost of Martinez's family membership for medical insurance is $3,900.

The company pays 50% of the cost.

So, the cost paid by the company= 50% of $3,900.

=\frac {50}{100}\times 3900=\$1850

The remaining cost for the family medical insurance must be paid by Gail Martinez.

So, the annual payment by her =$3900-$1850=$1850

Hence, she pays $1850  annually for medical insurance.

I'm assuming you have the octagonal base flat on the ground/floor. If so, then the horizontal cut through the center would basically cut the prism into two smaller equal pieces. Each piece will have the same octagonal base, but now the height is half as much. The cross section is the same as the base.

One way to picture it is to imagine you had a single room house with a very tall ceiling. Now place a floor between the top and bottom, midway through, so that you divide this house into too stories (each story being the same height). This new floor is a cross section, which is identical to the original floor of the house. Instead of a rectangular floor, picture the floor shape being an octagon.

<h3>Answer: Octagon</h3>

Answer:

y - 10 = 5(x - 15)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (15, 10) and (x₂, y₂ ) = (16, 15)

m = \frac{15-10}{16-15} = \frac{5}{1} = 5

Using (a, b) = (15, 10), then

y - 10 = 5(x - 15)
