Consider the figure shown. Classify each of the following statements as always true, sometimes true, or never true.m<1+m<4=180
m<1+m<2+m<3=180
m<2+ m<4=180
<2=<3
<2=<4
m<3=m<4

Answers

Answer:

Step-by-step explanation:

Let's analyze each statement and classify them as always true, sometimes true, or never true based on the figure provided:

1. m<1+m<4=180:

This statement is always true. In the figure, angles 1 and 4 are vertical angles, which means they are congruent. Therefore, m<1 = m<4, and their sum is always equal to 180 degrees.

2. m<1+m<2+m<3=180:

This statement is never true. In the figure, angles 1, 2, and 3 do not form a straight line. Therefore, the sum of m<1, m<2, and m<3 cannot be equal to 180 degrees.

3. m<2+ m<4=180:

This statement is sometimes true. In the figure, angles 2 and 4 are adjacent angles, and their sum can be equal to 180 degrees if they form a straight line. However, if angles 2 and 4 do not form a straight line, their sum will be less than 180 degrees.

4. <2=<3:

This statement is never true. In the figure, angles 2 and 3 are not congruent. Therefore, <2 is not equal to <3.

5. <2=<4:

This statement is sometimes true. In the figure, angles 2 and 4 can be congruent if they are vertical angles. However, if they are not vertical angles, they will not be congruent.

6. m<3=m<4:

This statement is always true. In the figure, angles 3 and 4 are vertical angles, which means they are congruent. Therefore, m<3 = m<4.

To summarize:

- Statement 1 is always true.

- Statement 2 is never true.

- Statement 3 is sometimes true.

- Statement 4 is never true.

- Statement 5 is sometimes true.

- Statement 6 is always true.

WILL MEDAL AND FANThe formula Q = MCT where Q = heat flow, M = mass, C = specific heat, and T = change of temperature is used to calculate heat flow. Solve this formula for T.

T = Q – MC
T = Q + MC
T = QMC
T = Q divided by the quantity M times C

Answers

The answer is T= Q divided by the quantity M times C. To solve for T, the goal is to isolate T from the rest of the factors which are M and C. To do this, divide M and C from both sides of the equation. This will cancel M and C from the right-hand side, leaving only T. So, there you have it, T is now equal to Q divided by the quantity M times C.
To solve this formula for T it is the last one.
T = Q divided by the quantity M times C.

Answers

Answer:

x=5\ny=5

Step-by-step explanation:

I solved using substitution

−1.6x−3.2y=−24

−1.6x=−24+3.2y

−1.6x=3.2y−24

x=-(3.2y-24)/(1.6\n)

2.6x+2.6y=26

−2.6y+39=26

−2.6y+39=26

−2.6y=26−39

−2.6y=−13

y =5
