Answer:
110°
Step-by-step explanation:
the supplement of an angle is 30 degrees less than twice the measure of the angle itself. find the angle and its supplement.
Let the angle be A, then its supplement = (180 - A)
Now, since the supplement is 30 degrees less than twice the measure of the angle itself, then we'll have:
180 - A = 2A - 30
-3A = - 210
A, or the angle = 
= 70 °
Its supplement, (180 - A) = 180 - 70 = 110°
Answer:
1. x² – 11x + 24
2. a² + 5a + 6
Step-by-step explanation:
1. (x – 3)(x – 8) =?
Use the entities in the first bracket to multiply the second bracket. This is illustrated below:
(x – 3)(x – 8)
x (x – 8) – 3(x – 8)
x² – 8x – 3x + 24
x² – 11x + 24
Thus, the product of (x – 3)(x – 8) is
x² – 11x + 24
2. (a + 3)(a + 2) =?
Use the entities in the first bracket to multiply the second bracket. This is illustrated below:
a(a + 2) + 3(a + 2)
a² + 2a + 3a + 6
a² + 5a + 6
Thus, the product of (a + 3)(a + 2) is:
a² + 5a + 6
A function should produce one output for one given input.
Therefore a function should pass the vertical line test.
From the figure,
a,b,c pass the vertical line test;
d fails the vertical line test.
Answer: Case d does not represent a function.

<span><u><em>Answer:</em></u>
36.156<span>
<u><em>Explanation:</em></u>
Multiply as 7.86 and 4.6 ignoring the decimals for now. You get a solution of 36156.
You count how many decimal points are in the problem (2 from 7.86 and 1 from 4.6) and you put it in the answer by moving the decimal to the left the amount of decimals in the problem this leave the answer as 36.156</span></span>
