The point (5, -1) is solution of equation: y= 2x - 11

1 answer:

6 0

Let's input the x value (5) and see if the output is correct (-1).

y = 2(5) - 11
y = 10 - 11
y = -1

(5, -1) is a solution to y = 2x - 11.

The only ordered pairs that are a solution to y = 8x are (2, 16), (1, 8), and (-3, -24).

y = 8(2)
y = 16

y = 8(1)
y = 8

y = 8(-3)
y = -24

If x=2y=4z, express

Umnica [9.8K]

$x = 4z$

$2y = 4z$

Dividing both sides by two,

$y = 2z$

OK, part 1.

$x+4y+z = 4z + 4(2z) +z = 13z$

When $z=2$ then $x+4y+z =13(2)=26$

Part 2.

$2x+3y+2z= 2(4z) +3(2z) + 2z = 16z$

When $z=2$ then $2x+3y+2z=16(2)=32$

Shkiper50 [21]

The after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

<h3>What is distance?</h3>

A numerical representation of the distance between two items or locations called distance. A physical length or an approximation based on other considerations in physics or common usage can be referred to as distance.

Let's suppose the at time t they are 47 miles apart.

We know, distance = speed×time

(44+51)t = 47

t = 47/95

t = 0.494 hours

t = 29 minutes 38 seconds

Thus, the after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

Which of the following describes the “p/2” in the expression above?

julia-pushkina [17]

Option B. Quotient is the right answer

Step-by-step explanation:

Given expression is:

p/2 +4(7+p)

Let us look at the options one by one

<u>A. factor</u>

p/2 is not a factor as the factor is always multiplied with another factor

<u>B. quotient</u>

This is the right answer as p is being divided by 2. The quotient of both will be used for further calculations

Hence,

Option B. Quotient is the right answer
