A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?
Gwar [14]

Answer:

The slope of line for given points is   \frac{12}{17}

Step-by-step explanation:

Given points of line as :

A  = ( - 7 , 15 ) i, e x_1 = - 7 ,  x_1 = 15

B = ( 10 , 27 )  i.e  x_2 =  10 , y_2 = 27

Let The slope of line be m

So , The slope with two points is given as equation

m = \frac{y_2 - y_1}{x_2 - x_1}

Or, m =  \frac{27 - 15}{10 + 7}

Or, m =  \frac{12}{17}

Hence The slope of line for given points is   \frac{12}{17} .  Answer

What is the value of t?<br> 3.5(t+6)=7<br><br> A. -4<br> B. -0.25<br> C. 0.25<br> D. 4
Gelneren [198K]
A because when you distribute you get 3.5t + 21 = 7. Then subtract 21 from both sides to get 3.5t = -14. Then divide both sides by 3.5t to get -4.

The length of a copper wire is 1.6 centimeters (cm). what is the length of this wire in meters (m)? 1.6 times. 10–3 m 1.6 times.
LUCKY_DIMON [66]

The length of the copper in meters is 1.6 times 10^-2 meters.

According to the given question.

The length of a copper is 1.6 centimeters.

As we all know that

1 meter = 100 centimeter

⇒ 1 centimeter = 1/100 meters or 10^-2 meters

So, to find the length of the copper wire in meters. We have to convert 1.6 centimeters to meters.

Therefore,

The length of the copper wire in meters

= 1.6/100 meters

= 1.6 × 10^-2

= 1.6 times 10^-2 meters

Hence, the length of the copper in meters is 1.6 times 10^-2 meters.
