Answer:

Yes but there is only one way to check they are an ordered pair.

This is done by using simultaneous equations

ascending line is  y = 2x + 9

descending line is  y = -2x + 7

The ordered coordinates can be checked ( -4, 1)

2 (-4) + 9(1) = 1

and

-2 (4) +7 (1) =  -1

Joanna plans on hanging 3 pictures of different sizes on the wall of her staircase. She thinks it will look best if all 3 rectan
Natasha2012 [34]
In similar figures, the ratio between corresponding sides are the same.

\frac{25}{35}=\frac{35}{49}

Simplify the two to see that they are equal.
The top and bottom of the left fraction are divisible by 5.
The top and bottom of the right fraction are divisible by 7.

\frac{5}7=\frac{5}7

Of course, the dimensions of that third picture would have to be this fraction.
Let's test these answers.

\frac{5}6\neq\frac{5}7 ⇒ A is not a solution

\frac{30}{42}=\frac{5}7 ⇒ B is the solution
(divide the top and bottom by 6)

Fill in the table using this function rule. y=-3x-3 ​
pashok25 [27]

Answer:

When x = -2, y = 3

When x = -1, y = 0

When x = 0, y = -3

When x = 1, y = -6

Step-by-step explanation:

Given:

y = -3x - 3

Fill in the table using the following value for x

When x = -2

y = -3x - 3

y = -3(-2) - 3

y = 6 - 3

y = 3

When x = -2, y = 3

When x = -1

y = -3x - 3

y = -3(-1) - 3

y = 3 - 3

y = 0

When x = -1, y = 0

When x = 0

y = -3x - 3

y = -3(0) - 3

y = 0 - 3

y = -3

When x = 0, y = -3

When x = 1

y = -3x - 3

y = -3(1) - 3

y = -3 - 3

y = -6

When x = 1, y = -6

What is the answer X/7-3>8
mamaluj [8]

Answer:

x > 77

Step-by-step explanation:

According to order of operations rules, we must carry out division before addition or subtraction.  In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:

X/7-3>8

     +3 +3

--------------

x/7 > 11

The easiest way in which to solve for x is to multiply both sides of this inequality by 7:

7(x/7) > 7(11), or

x > 77

All numbers greater than 77 are part of the solution set.
