Step-by-step explanation:
The reaction NaCL + AgNO3 → NaNO3 + AgCL is a replacement reaction.
The given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.
When elements swap positions in compounds, a replacement reaction takes place. Ions are involved in this kind of response. In most cases, more reactive elements take the place of less reactive ones. When one element replaces another in a compound, it is known as a single replacement reaction.
Here,
In the given chemical reaction, Na is replaced by Ag, As per the above definition of the replacement reaction.
NaCl + AgNO3 = Na- cl + Ag-NO3 → NaNO3 + AgCl
Thus, the given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.

Answer:
She listed a scale factor of 1/3.
She is wrong because the larger figure has the dashes around the letters meaning it is the result of the scaling. To find the answer without doing all the work again she should find the reciprocal of 1/3. The answer should be 3.

Answer:
x=5.9
Step-by-step explanation:
Answer:
x=5.9 or 5.9=x
Step-by-step explanation:
Equation: 14=31.7-3x
Subtract 31.7 on both sides:
14=31.7-3x
-31.7 -31.7
Solve:
-17.7=-3x
Divide -3 on both sides:
-17.7/-3=-3x/-3
Answer:
x=5.9 or 5.9=x

Describe the relationship between the corresponding ANGLES in an original figure and the new figure resulting from a dilation.
The difference between two same-side interior angles of two parallel lines is 35 degrees. Find the measures of these two angles.
WILL GIVE BRAINLIEST
Answer:
angle 1: 72.5°
angle 2: 107.5°
Step-by-step explanation:
x + y = 180
x - y = 35 ===> x = 35 + y
Substitution to find angle y:
x + y = 180
(35 + y) + y = 180
35 + 2y = 180
2y = 145
y = 72.5
Substitution to find angle x:
x = 35 + y
x = 35 + (72.5)
x = 107.5
Answer:
The measures of the angles would be 107.5 and 72.5.
Step-by-step explanation:
The angles should up to 180 degrees.
You can make two equations to solve it:
x+y=180
x-y=35
You add both of the equations.
2x = 215
X = 107.5
Y = 72.5

What is the equation of the line that passes through the point 4,4 and has a slope of 0?
Answer:
y = 0x + 4 or y = 4.
Step-by-step explanation:
The slope is zero, and in other words, m = 0.
The slope intercept form is y = mx + b.
Replace m with 0.
y = 0m + b.
The y intercept is the y point on the line. Since this slope is a straight horizontal line, the y point given is the y intercept. b is the y intercept.
y = 0m + 4
Since any number times 0 is 0 you can right it as
y = 4.
The equation of a line that passes through a point is an algebraic equation. It can also be referred to as the Slope-Intercept Equation.
The equation of the line that passes through the point (4, 4) and has a slope of 0 is written as: y = 4
The equation of the line through a point (x1, y1) can be represented by the algebraic equation:
y = mx + c
where:
m = slope
c = y - intercept
From the question,
(x1, y1) = (4, 4)
m = slope = 0
Substituting these values into the algebraic equation,
4 = (0 x 4) + c
Hence, y = 4
The equation of the line that passes through the point (4, 4) and has a slope of zero is y = 4

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Answer:
You would use miles when describing a long distance.
Step-by-step explanation:
For example, when describing how far away is a city from another city you would use miles. That is because you are describing a long-distance and inches would be a very larger number and hard to tell how far it really is.
