The correct option is (B)

Step-by-step explanation: We are given to match the graph with its correct equation.

From the graph, we note that

there is a straight line where the points (7, 0) and (0, -7) lie on it.

So, the slope of the line is given by

Since the line passes through the point (7, 0), so its equation will be

Thus, the required equation of the graphed line is

Option (B) is CORRECT.

Match the graph with its equation.

7x + 7y = 0

7x – 7y = –49

7x + 7y = 49

–7x +7y = –49

A sports club has 38 members. They all play either squash or tennis.

Brut [27]

Step-by-step explanation:

Since we have given that

Total number of members in a sports club = 38

Number of women in the club = 14

Number of women play tennis =10

Number of men play tennis = 8

Since they all play either squash or tennis.

Total number of men in the club is given by

$38-14\\\\=24$

So, number of men playing squash is given by

$24-8\\\\=16$

Number of women playing squash is given by

$20-16\\\\=4$

so, the table is shown below :

Men Women Total

Tennis 16 4 20

Squash 8 10 18

Total 24 14 38

Distance between points (7,6) (-3,-1)

GaryK [48]

Answer:

Step-by-step explanation:

(7,6) (-3,-1)

(x1,y1) (x2,y2)

$Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\=\sqrt{(-3-7)^{2}+(-1-6)^{2}}\\\\=\sqrt{(-10)^{2}+(-7)^{2}}\\\\=\sqrt{100+49}=\sqrt{149}\\\\=12.21$

Brass is made up of copper and zinc. 100 grams of brass contains 20 grams of zinc.

Nana76 [90]

Answer:

A. 12 grams Zn

B. 280 g of copper.

Step-by-step explanation:

100 grams of brass

20 grams of zinc

100 grams of brass has 20 grams of Zn.

20/100 = 0.200 Zn <u>20% Zn and 80% copper</u>.

A. (60 g brass)*(0.2) = 12 grams Zn

B. (350 g brass)*(0.80) = 280 g of copper.

What is 0.3636363636 to the nearest thousandth?

Bad White [126]

Answer: 0.364

The reason that it would be 0.364 is because the thousandths place is the third decimal place, which would leave you with a 3 but since there is a 6 after the 3, the 3 would be rounded up to a 4.
