Answer:

x =6 and y=4

(6, 4)

Step-by-step explanation:

We can solve this equation by either using elimination method, substitution method or both method.

In this case we will use substitution method

x + 2y = 14  ------------------------(1)

у= 3х - 14 -------------------------(2)

substitute equation (2) into equation (1)

x + 2(3x-14) = 14

x + 6x -28 = 14

7x -28 =14

Add 28 to both-side of the equation

7x - 28 + 28 = 14 + 28

7x = 42

Divide both-side of the equation by 7 to get the value of x

7x/7 = 42/7

(on the right-hand side of the equation 7 at the numerator will cancel-out 7 at the denominator leaving us with just x while on the right-hand side of the equation 42 will be divided by 7)

x = 42/7

x =6

substitute x=6 into equation (2)

y = 3x -14

y = 3(6) - 14

y = 18 -14

y =4

Therefore x =6 and y =4

(6, 4)

Answer:

y=28/5

x=14/5

Step-by-step explanation:

use substitution

x=14-2y

y=42-6y-14

0=42-5y-14

0=28-5y

y=28/5

x+56/5=14

x=14-56/5=14/5

Maureen tracks the range of outdoor temperatures over three days. She records the following information.
Shkiper50 [21]
<h2>Hello!</h2>

The answer is:

The correct option is the third option;

-23\leq t\leq 50

<h2>Why?</h2>

To find which of the options expresses the intersection of the three days as an inequality in terms of temperature "t" we need to find an inequality which starts at the lowest temperature (greater or equal) and finish at the highest temperature (less or equal).

So, we have that the lowest temperature is -23°F and the highest temperature is 50°F, there are two options for that range, but we need to consider that the temperature will range from -23° to 50°, so, the correct option is the third option;

-23\leq t\leq 50

We can see that the inequality express that the temperature will range from -23°F being greater or equal than that, to 50°F being less or equal than that.

Have a nice day!

finlep [7]

Answer:

y= -4/3x - 1/2 is the perpendicular line to y= 3/4x -1/2

Step-by-step explanation:

The slope would be the negative reciprocal of your current slope :)

+3/4 would turn into -4/3 and you wouldnt change the y intercept

hope this helps
