how can you tell if an ordered pair (x,y) is a solution or a system of linear equations?
Answer:
you will know because it you do the system of whatever thingy and there are no two dots in the same row and the line is straight in either a negative or positive slope at a diagonal the equation is linear and its a function.
Step-by-step explanation:
The image is an example of a linear equation that is both a function and positive lenear
Answer:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Answer:
A) 4(7+x)=64
B) 4x+7=64
Step-by-step explanation:
A
4(7+x)=64
*Disturabute 4 to (7+x)*
28+4x=64
*Subtract 28 on both sides*
4x=36
*Divide by 4*
x=9
**If you do a Check it works*
B
4x+7=64
*Subtract 7*
4x=57
*Divide by 4*
x=14.25
**If you do a Check this also works**
Hope This Helps!!!

Solved the inequality incorrectly and graphed their solution incorrectly.
Solved the inequality correctly but graphed their solution incorrectly.
Solved the inequality incorrectly but graphed their solution correctly.
Solved the inequality correctly and graphed their solution correctly.
Answer:
solved the solution incorrectly and graphic their solution correctly.
Step-by-step explanation:
this is because if 4x + 1<= -4
the next step will be to subtract 1 from both sides.
BUT if their solution is x<= 2, they objectively graphed it correctly
Step-by-step explanation:
4x+1 < -4
-1 -1

Rectangle A′B′C′D′ is the image of rectangle ABCD after a dilation.
What is the scale factor of the dilation?
Enter your answer in the box.
Answer:
The dilation's scale factor is 1/2.
Step-by-step explanation:
What we know:
Square ABCD's side lengths are all 3.
-2 - (-5)
-2 + 5 = 3
-5 - (-8)
-5 + 8 = 3
Square A'B'C'D''s side lengths are all 1.5.
-2.5 - (-4)
-2.5 + 4 = 1.5
-1 - (-2.5)
-1 + 2.5 = 1.5
Divide the scale (A'B'C'D') by the original (ABCD) to get the scale factor
1.5/3 = 1/2 as the scale factor of the dilation

This graph shows a proportional relationship between the amount of money in Jack’s savings account and the number of weeks Jack has been saving money.
Which statement identifies the correct slope, and the correct interpretation of the slope for this situation?
A
The slope of the line is 61 , so Jack is saving $6 per week.
B
The slope of the line is 61 , so Jack' is saving $1 for every 6 weeks.
C
The slope of the line is 16 , so Jack is saving $6 for every 1 week that passes.
D
The slope of the line is 16 , so Jack is savings $1 for every 6 weeks that passes.
The slope of the line is 6, which can be interpreted as Jack saving $6 per week. (Option A).
Recall:
Proportional relationship between two quantities can be given as: y = mx, where m = slope.
Slope (m) = y/x (of a graph that is proportional)
Given the proportional graph, using a point on the line, (5, 30):
Slope (m) = [tex]\frac{30}{5} = 6[/tex]
Therefore, the slope of the line is 6, which can be interpreted as Jack saving $6 per week. (Option A).
