Answer:
Value of x --> 15°
<u>Step-by-step explanation:</u>
(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.
---> (2x + 60°) + 6x = 180°
2x + 60° + 6x = 180°
8x + 60° = 180°
8x = 180°- 60°
8x = 120
x = 
<h3><u>x equals 15°</u></h3>
43 is a prime number, so
it has factors only 1 and 43, You can write only 43*1=43.
Answer:
y = -8x -3
Step-by-step explanation:
To find the y intercept of a basic y = mx + b equation you simply find the constant (In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number). To find the slope of a basic y = mx + b equation find the value of m. The value of m will be the slope.
Answer:
Option D doesn't make any sense.
Step-by-step explanation:
D) 7 hours of sleep correspond to an age of 19 years.
That is wrong.
If we use the expression provided
hours = 8 + 0.5*(18 -age)
hours = 8 + 0.5*(18 -19)
hours = 8 + 0.5*(-1)
hours = 7.5
