Answer:

Option 2 is correct that is It is a line joining the points whose x and y-coordinates add up to 5.

Step-by-step explanation:

We have been given the expression:

$x+y=5$

So, we can see that the sum of x-coordinate and y-coordinate is 5.

it is a straight line here, x-intercept is (5,0) and y-intercept is (0,5)

You can see the graph of the line in the attachment.

Therefore, option 2 is correct that is It is a line joining the points whose x and y-coordinates add up to 5.

It's defined by x+y=5 hence the sum of the x-coords and the y-coords is 5. Any point such that his x-coord and y-coord add up to 5 is on the line.

1 is hence False and 2 is True.

(5,5) is on none of the axus, so it can't be 3 or 4.

The answer is 2

Solve the equation using the distributive property and properties of equality. One-half (x + 6) = 18 What is the value of x? 6 7

butalik [34]

Answer:

The value of x is 30.

We have to find the value of x in the given equation.

Using distributive property

We have,

$1/2(x+6)=18\\a.(b+c)=a.b+a.c\\1/2(x+3)=18\\1/2x=15\\x=3$

other are also solve by this methode;)

Graph the linear equation find three points that solves the equation 2y=5x+11

Julli [10]

Answer:

<h3>Attachment</h3>

Step-by-step explanation:

Convert to the slope-intercept form (<em>y = mx + b</em>):

$2y=5x+11$ <em>divide both sides by 2</em>

$\dfrac{2y}{2}=\dfrac{5x}{2}+\dfrac{11}{2}\\\\y=\dfrac{5}{2}x+\dfrac{11}{2}$

We choose any three x values and calculate the y value:

for x = -1

$y=\dfrac{5}{2}(-1)+\dfrac{11}{2}=-\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{6}{2}=3\to A(-1,\ 3)$

for x = 1

$y=\dfrac{5}{2}(1)+\dfrac{11}{2}=\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{16}{2}=8\to B(1,\ 8)$

for x = -3

$y=\dfrac{5}{2}(-3)+\dfrac{11}{2}=-\dfrac{15}{2}+\dfrac{11}{2}=-\dfrac{4}{2}=-2\to C(-3,\ -2)$

Mark the points on the coordinate plane and draw a line through the given points.

Can someone help its math :)

Answer:

m<F = 53

Step-by-step explanation:

Exterior angles thm:

5x - 10 + 3x + 14 = 100

8x + 4 = 100

8x = 104

x = 13

m<F:

3x + 14

3(13) + 14

39 + 14

5 ( n - 7 ) = 2 ( n + 14 )

wariber [46]

Answer:

n=21

Step-by-step explanation:

We must find n.

Remember PEMDAS. First we must do the Parentheses. Lets do distributive property by multiplying a number that is immediately outside the parentheses with each number inside the parentheses. Lets do this one side at a time.

First lets do 5(n - 7). We get 5n - 35

Now 2(n + 14) is 2n + 28

Okay...... now we have $5n-35=2n+28$
