Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
Answer:
x= 3.57
Step-by-step explanation:
32 ( x + 2.5) = 114.24
32* x + 32* 2.5= 114.24
32x + 80= 114.24
-80 -80
32x= 114.24
/ 32 /32
x= 3.57
for the part that says convince me, we can use the eqution
/= divide
The answer is false I hope this helps
Answer:
Q1. The estimated sum of the two people are between 40 and 55 years old.
Q2. The first person is between 10 and 15 years older.
Step-by-step explanation:
We are given Age Range's for 2 people. The first question is asking for the sum of the two people's ages. In this case we can just <u><em>add</em></u> the two minimum ages together and then the two maximum ages like so,
<u>min:</u> 25 + 15 = 40
<u>max:</u> 35 + 20 = 55
So the estimated sum of the two people are between 40 and 55 years old.
The second question asks how much older the First person is from the Second person. We can calculate this by <u><em>subtracting</em></u> both age ranges like so,
<u>min:</u> 25 - 15 = 10
<u>max:</u> 35 - 20 = 15
So the first person is between 10 and 15 years older.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
Part A - D:8
Part B - C:140°
<h3>Solving/Reasoning:</h3>
Part A: Vertical angles are always congruent.
Part B: If angles are supplementary, they need to equal 180 when added together. Since we know angle A is 40, we can subtract it from 180 and figure out what is left over that should be angle B.
40+B=180
B=180-40
B=140
