Is the ordered pair (-2, 9) a solution of the equation y = x – 7?

2 answers:

No because if you plug in the ordered pair you would get 9=-2-7 which equals -9 making -9 and 9 unequal means (-2,9) is not a solution.

To find if (-2,9) is a solution of the equation y = x - 7, just plug the values back into the original equation. You can get these values by using the coordinate point.
$9 = -2 - 7
$
$9 ≠ -9$
Since the values are not equal, the coordinate point (-2,9) is not a solution of the equation y = x - 7. Hope this helps and have a fabulous day!

Solve the inequality and explain the stores for the two questions below:

Taya2010 [7]

Answer:

a < 3

n < 3

Step-by-step explanation:

We will solve each inequality one by one.

Solve first inequality :

3a - 4 < 5

add 4 both the side

3a < 9

divide 3 both the side

a < 3

Solve second inequality:

$\frac{n}{-3} + 5 > 4$

subtract 5 both the side

$\frac{n}{-3} > -1$

now multiply by -3 both the side and reverse the inequality sign

n < (-3)*(-1)

n < 3

That's the final answer. I hope it will help you.

victor has the map scale missing.he knows the distance from the lake to the youth center is 8 miles. on the map they are 2in. ap

kupik [55]

The correct scale is 1 in = 4 mi.

Explanation:

The scale tells us what a given measurement on the map equals in real-life distance.

The measurement on the map that we have is 2 inches, and it equals 8 miles:

2 in = 8 mi

This can also be written as 2/8. This fraction can be simplified, since both 2 and 8 are divisible by 2; it will simplify to 1/4. This is the same as
1 in = 4 mi.

PLEASE HELP!!!!

Answer:

3rd angle of a triangle = x = 75°

Step-by-step explanation:

1st angle of a triangle = 50°

2nd angle of a triangle = 55°

3rd angle of a triangle = x = ?

We know that sum of three angle of triangle = 180°

1st angle of a triangle + 2nd angle of a triangle + 3rd angle of a triangle = 180°

50° + 55° + x = 180°

105° + x = 180°

x = 180° - 105°

x = 75°

3rd angle of a triangle = x = 75°

What is the 74th term of this arithmetic sequence? -25, -21, -17, -13,-9, -5,...

xz_007 [3.2K]

Answer:

267

Step-by-step explanation:

let's say that

f(0)=-25

so in the sequence we are adding 4

so f(1)=-25+4=-21

and f(2)=f(1)+4=-25+4+4=-25 + 4(2)

so if you continue you will notice that

f(n)=-25+4(n)

so our question is

What is the 74th term of this arithmetic sequence?

so if f(0) is our first term, the 74th will be f(73)

so we can apply our formula

f(73)=-25+4(73)

=-25+292

=267
