Line l passes through the point (4 1) and (7 3) while line n passes through the points -3,5 and -9,1

Molodets [167]

Line M :
(4,1),(7,3)
slope = (3 - 1) / (7 - 3) = 2/3

Line N :
(-3,5),(-9,1)
slope = (1 - 5) / (-9 - (-3) = -4 / (-9 + 3) = -4 / -6 = 2/3

Line M and line N have the same slope...so they are parallel

What's the correct answer I'm so confused

Ksju [112]

Like before, we will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the TK = 65 corresponds to the MV = 30. Therefore, TU = 39 corresponds to the LM = x .

65 : 30 = 39 : x

x = (30*39)/65

x = 1170/65

x = 18.

The correct answer is C. 18.

Solve the following multiplication and division problems.

algol13

Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. $(4.2)(10^{-5})$ km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

$\frac{5hm}{10}=0.5km$

$(3km)(0.5km)(15)=22.5km$

b. You can convert from centimeters to meters, and then you can make the multiplication:

$\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m$

c. You only need to divide 1,140 meters by 12:

$\frac{1,140m}{12})=95m$

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

$\frac{6hm}{10}=0.6km$

$\frac{7dam}{100}=0.07km$

$\frac{5m}{1000}=0.005km$

$\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5})$ km
