Answer:

It is C and D :)

Step-by-step explanation:

Each input is multiplied by 2 to get the output which is why it is C. The coordinates are just the input as the X value and the output as the Y value, which is why it is also D.

Hope this helps can I have brainliest pls

A car is traveling on a highway at a constant speed, described by the equation d = 70t, where d represents the distance, in mile

Answer:

84miles

Step-by-step explanation:

Step one:

given data

we are told that the equation that describes the car's speed is

d = 70t-----------1

From the equation, we can see that the speed with which the car is traveling is 70miles per hour, while we are expected to find the distance d when the time is 1.2 hours.

Required

The distance d at 1.2 hours

Step two:

substituting in the expression we have

d= 70*1.2

d=84miles

Answer:

19.41 units

Step-by-step explanation:

Given coordinates of points;

(-10, 9)
(-6, -10)

To determine the distance between the two points, the distance formula is required. The distance formula is used where it is not possible to calculate the distance through a straight line. The distance formula is expressed as,

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

The distance between the two points can be determined by plugging the coordinates into the formula;

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$
⇒ $\sqrt{[-6 - (-10)]^{2} + [-10 - 9]^{2} }$

Then, we can simplify the root as needed to determine the distance;

⇒ $\sqrt{[-6 + 10]^{2} + [-19]^{2} }$
⇒ $\sqrt{[4]^{2} +361 }$
⇒ $\sqrt{16 +361 }$
⇒ $\sqrt{377}$

Finally, we need to convert the root into decimals (stated in question). It is impossible to determine the root in decimal form. Therefore, I used a calculator to determine the distance in decimal form.
