Answers
A)2x^2 + 3x - 12
2(2^2) + 3(2) - 12
2(4) + 6 - 12
8 + 6 - 12
14 - 12 = 2
2
3x(x-2) + 2
3(2) * (3-2) + 2
6 * 1 + 2
6 + 2 = 8
Nope, these are not equivalent.
Next one, x = 7
2x^2 + 3x - 12
2(7^2) + 3(7) - 12
2(49) + 21 - 12
98 + 21 - 12
119 - 12 = 107
3x(x-2) + 2
3(7) (7-2) + 2
21(5) + 2
105 + 2 = 107
Yes! When x = 7, these expressions are equal.
B) 2x^2 + 3x - 12
Apply the value for x.
2(5^2) + 3(5) - 12
2 (25) + 15 - 12
50 + 15 - 12
55 - 12 = 43
3x(x-2) + 2
3(5) * (5-2) + 2
15 * 3 + 2
45 + 2

When x = 5, these expressions are not equivalent.

2. | 3x - 2 | = 8 | x + 1 | = 1
3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2
ur answer is : x = -2
3. 3y - 4x + 5 = 0

3. You are 13 years old, and your cousin is 19 years old. As you grow older, is your age proportional to your cousin's age? Explain your reasoning
Answers
Answer:
1. The relation is proportional.
2. The ratio of quarters and to dimes will not remain 5 : 3.
3. y = 6 + x, Hence, not proportional.
Step-by-step explanation:
1. I can do 90 sit-ups in 2 minutes and my friend can do 135 sit-ups in 3 minutes.
If we consider t as the time in minutes and n as the number of sit-ups, then we can write (2,90) and (3,135) as two ordered pairs.
So, the relation between t and n will be
⇒ n = 45t
Therefore, the relation is proportional.
2. The initial ratio of quarters to dimes was 5:3. If I add the same number of quarters and dimes to it then,
a) The ratio of quarters and dimes will not still be 5 : 3.
b) Let, the number of quarters was 5 then the number of dimes was 3. {As the ratio was 5 : 3}
Now, we add 3 new quarters and 3 new dimes in the collection. then, finally, the number of quarters will be (5 + 3) = 8 and the number of dimes will become (3 + 3) = 6.
Therefore, the new ratio will become 8 : 6 = 4 : 3 which is not equal to 5 : 3.
3. I am 13 years old, and my cousin is 19 years old.
So, if my age is given by x and that of my cousin is y, then
y - x = 19 - 13
⇒ y - x = 6
⇒ y = 6 + x
This relation will continue as the year passes. So, the relation is not proportional as the relation is not like y = kx. (Answer)
