Two lines, M and N, are represented by the following equations:


Line M: y = x + 3

Line N: y = −2x + 6


Which of the following options shows the solution to the system of equations and explains why?


(1, 4), because the point does not lie on any axis

(1, 4), because one of the lines passes through this point

(1, 4), because both lines pass through this point

(1, 4), because the point lies between the two axes

Answers

Answer 1

Answer:

Third answer shown

Step-by-step explanation:

Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.

                                                    x + 3 = -2x + 6

Add 2x to both sides.                2x          2x

                                                   3x + 3 =  0 + 6

                                                   3x + 3 = 6

Subtract 3 on both sides.                -3     -3

                                                      3x    =    3

Divide both sides by 3.                   x = 1

Now, let's see what y must be if x equals 1.

Line M:  y = x + 3 -->  y = 1 + 3 --> y = 4

Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed

So the ordered pair (x, y) that satisfies both equations is (1, 4)

*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.

That is the third answer shown.

Simplify: 14ba2+21ab2−ab2.

Answers

14ba^2+20ab^2 because you subtract one from 21ab^2

The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².

What is simplification?

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

The expression is given in the question, as follows:

14ba²+21ab²−ab²

When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².

Thus, the given expression can be simplified to 14ba²+20ab².

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?

Answers

Answer:

7 & 8

Step-by-step explanation:

29÷4=7.25

7<7•25<8

The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet

Given data ,

A 4-story building is 29 feet tall

So , the height of the each story is given by the equation ,

To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).

A = 29/4

On simplifying the equation , we get

29 feet ÷ 4 stories = 7.25 feet per story

Now , the inequality representing the height of the building between the whole numbers is given by

7.25 lies between 7 and 8

So , the inequality is 7 < A < 8

Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y​

Answers

Answer:

The value of x is 2.

The value of y is [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

x:

We have that:

[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]

Multiplying everything by 3

[tex]x + 3 = 5[/tex]

[tex]x = 2[/tex]

The value of x is 2.

y:

We have that:

[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]

Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.

[tex]6y - 4 = 3[/tex]

[tex]6y = 7[/tex]

[tex]y = \frac{7}{6}[/tex]

The value of y is [tex]\frac{7}{6}[/tex]
