Answer:

x = -3

Step-by-step explanation:

the lines in the form:

y = a , where a is a constant is a horizontal line

and

x = b, where b is a constant is a vertical line

To find lines that are parallel to the horizontal and vertical lines with point given (n,p), we follow the rule below:

1. If we have a line y = a and goes through point (n,p), the parallel line will have equation y = p

2. If we have a line x = b and goes through the point (n,p), the parallel line will have equation x = n

Now, this question gives a vertical line x = -11 and we need to find line parallel to this that goes through (-3,9). So, from RULE #2 above, we can say the parallel line's equation would be:

x = -3

Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G (1,3) H (4,3) J (5,1) and K (2,1

Basile [38]

Answer: (3,2)

Step-by-step explanation: Diagonal is a line connecting two opposite points of a form. In parallelograms, there two diagonals and they bisect each other, i.e., the point where the diagonals meet divide them into two segments with the same measure. In short, diagonals meet at their midpoint.

The way to determine midpoint is given by

(x,y) = ${\frac{x_{1}+x_{2}}{2} },\frac{y_{1}+y_{2}}{2}$

(x,y) = ${\frac{1+5}{2} },\frac{3+1}{2}$

(x,y) = (3,2)

The coordinates where diagonals of parallelogram GHJK intersect are (3,2).

Add using the number line. 7+(−10) Drag and drop the word SUM to the correct value on the number line.

Amiraneli [1.4K]

Steps of adding 7+(-10) using number line are as following:

1) Draw a number line by ranging from -10 to +10.

2) Point out 7 on the number line.

3) Because -10 is added to 7 on the number line, please move 10 numbers left to 7 on the number line. We always go left in addition of a negative number on the number line.

4) The number we reach -3 on left side would be our final sum.

5) From the number we can clearly see that moving 10 number on left to 7, we get -3.

Note: We are moving left because of negative sign in front of 10.

Write each polynomial in standard form. Then give the leading coefficient. You may need to combine like terms before writing the

Bond [772]

Step-by-step explanation:

To write a polynomial in standard form, put the degree that are the greatest first

So here it would be

${x}^{5} + 4 {x}^{3} - 3 {x}^{2} + 10$

Remember constant are numbers that you learned back in elementary,

Numbers like 10,90,4,1,0,-3 etc.

Remember that constant are basically represented like this

$k \times {x}^{0}$

For example, 10 is represented like

$10 \times {x}^{0}$

Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form

motorcycle cover 210 kilometre distance with 5 l of petrol how many kilometre does it cover with 8 litre of petrol? how much pet

Likurg_2 [28]

Answer:

A: 336 km

B: 14 L

Step-by-step explanation:

Use a proportion

210 km / 5 L = x / 8L Cross multiply

8*210 = 5 x

1680 = 5x

x = 1680 / 5

x = 336 km

===============

210 /5 = 588/x Cross multiply

210x = 588 * 5

210x = 2940 Divide by 210

x = 2940/210

x = 14 L
