which of the following part of triangle can be proven congruent by AAS
Answer:
A
Step-by-step explanation:
The other triangles use other congruency theorems, so if you look at the lines that indicate the angles and sides are congruent, A is the only option with two angles which are congruent with a congruent side after it.

Is EFG - HJK? If so, name the postulate that applies.
Given
EF-HJ
EG - HK
FG JK
G
O A. Congruent - SSS
B. Congruent - SAS
O C. Congruent - ASA
D. Might not be congruent
Answer:
Step-by-step explanation:
It’s A
The triangles EFG and HJK are congruent as all three sides of triangle EFG are given equal to the three sides of triangle HJK.
The postulate applied here is Side-Side-Side (SSS) postulate.
Thus, we can select option A. Congruent - SSS.
When are two triangles congruent?Two triangles are congruent when their shape is identical and their size is equal, that is, the three sides are equal and the three angles are also equal.
Congruency in triangles can be proven by the following postulates:
Side-Side-Side (SSS) postulate: When all three sides are equal.Side-Angle-Side (SAS) postulate: When two sides are equal and the angle containing them is also equal.Angle-Side-Angle (ASA) postulate: When two angles and the side common to them are equal.Angle-Angle-Side (AAS) postulate: When two angles and a non-included side are equal to the corresponding part.Right-Hypotenuse-Side (RHS) postulate: In a right triangle, the hypotenuse and a side are equal.How to solve the question?In the question, we are asked if EFG - HJK (EFG is congruent to HJK), when we are given that:
EF = HJ
EG = HK
FG = JK.
And if they are congruent, by which postulate it is so.
The triangles EFG and HJK are congruent as all three sides of triangle EFG are given equal to the three sides of triangle HJK.
The postulate applied here is Side-Side-Side (SSS) postulate.
Thus, we can select option A. Congruent - SSS.

Is the following a linear function? y= 3 + x2
Answer:
Yes I belive so
Step-by-step explanation:
Answer:
Yes, this is a linear function.
Step-by-step explanation:
A linear function is represented as y = mx + b. This is because slope intercept form represents a constant rate. This function above(y = 3 + x2) is represent as y = b + xm, which is a mixed up version of y = mx + b, but it leads to the same approximate rate.

Susan and John are buying cold drinks for a neighborhood picnic. Each person is
expected to drink one can of soda. Susan says that if you multiply the unit
price for a can of soda by the number of people attending the picnic, you will
be able to determine the total cost of the soda. John says that if you divide
the cost of a 12-pack of soda by the number of sodas, you will determine the
total cost of the sodas.
Answer:
Susan has suggested a correct method to calculate the amount of money
Step-by-step explanation:
Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.
Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.
John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.
Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.

The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost. What equation will you use to find the number of weeks x you will need to save?
Answer:
a) The equation will you use to find the number of weeks x you will need to save is:
270 = 95.50 + 20x
b) The number of weeks x = 8.725 weeks
Step-by-step explanation:
Let:
The cost to join the Ski club = y
The number of weeks you will need to save = x
From the question, we have the following information:
The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.
The equation will you use to find the number of weeks x you will need to save is:
y = $95.50 + $20 × x
y = $270
Hence:
270 = 95.50 + 20x
Solving for x
270 = 95.50 + 20x
270 - 95.50 = 20x
174.5 = 20x
x = 174.5/20
x = 8.725 weeks
Hence, the number of weeks needed to save is 8.725 weeks
Answer:Answer:
a) The equation will you use to find the number of weeks x you will need to save is:
270 = 95.50 + 20x
b) The number of weeks x = 8.725 weeks
Step-by-step explanation:
Let:
The cost to join the Ski club = y
The number of weeks you will need to save = x
From the question, we have the following information:
The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.
The equation will you use to find the number of weeks x you will need to save is:
y = $95.50 + $20 × x
y = $270
Hence:
270 = 95.50 + 20x
Solving for x
270 = 95.50 + 20x
270 - 95.50 = 20x
174.5 = 20x
x = 174.5/20
x = 8.725 weeks
Hence, the number of weeks needed to save is 8.725 weeks
Step-by-step explanation:
write the equation of the line if fully simplified slope in intercept form
Answer:
As we have seen before, you can write the equation of any line in the form of y = mx + b . This is the so-called slope intercept form, because it gives you two important pieces of information: the slope m and the y-intercept b of the line. You can use these values for linear interpolation later.
