Answer: no it isn’t
Step-by-step explanation:
Cuz 2(-1)+3(4)=14
-2+12=14
10 doesn’t equal 14

Answer:
Step-by-step explanation:
This question is about the benefits of estimation.
1300/13 is easy and results in 100.
1287/13 can be approximated by 1300/13: 1287/13 ≈ 100.
Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.
So: 1287/13 = 1300 - 13 = 1287. A nice bit of mental math!
The measure of its supplementary angle is 42 degrees
The sum of supplementary angle is qual to 180 degrees
Let the required angle be x
The sum of the supplements of 138 degrees will be expressed as:
x + 138 = 180
x= 180 - 138
x = 42 degrees
Hence the measure of its supplementary angle is 42 degrees

Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3
