Answer:
Like Terms: and .
Coefficients: and .
Constant:
Step-by-step explanation:
"Like terms" are terms whose variables (and their exponents such as the in ) are the same. In other words, terms that are "like" each other.Example: , , and are like terms because they all have .
Coefficients are a number used to multiply a variable. In the above example, the coefficients would be , , and . In your problem, they're and .
Constants are numbers not attached to variables. See the diagram attached.
Let me know if there are further questions.
Answer: 3m and 2n
Step-by-step explanation:
Answer: C, 3 to 2
Step-by-step explanation:
The highest common multiple of the 2 numbers is 9, 27 divided by 9 is 3, 18 divided by 9 is 2.
I guess you mean that the zeroes are 2 and -3/5.
In factor form the function could be
f(x) = (x - 2)(3x + 5)
expanding we get
f(x) = 3x^2 -x - 10
Answer: 4
<u>Step-by-step explanation:</u>
Let P represent Pete's age today. Let C represent Claire's age today.
2 years ago: P - 2 = 3(C - 2) ⇒ P - 2 = 3C - 6 ⇒ P = 3C - 4
4 years ago: P - 4 = 4(C - 4) ⇒ P - 4 = 4C - 16 ⇒ P = 4C - 12
Use substitution to solve the system above:
3C - 4 = 4C - 12
- 4 = C - 12
8 = C
Plug in the C-value above into one of the equations to solve for P:
P = 3C - 4
= 3(8) - 4
= 24 - 4
= 20
So, Pete is 20 yrs old today and Claire is 8 years old today
When will Pete be twice as old as Claire?
20 + x = 2(8 + x)
20 + x = 16 + 2x
20 = 16 + x
4 = x
Their ages will have a 2:1 ratio in 4 years.
