Answer:
(4 – 5) – (13 – 18 + 2)
= -1-(13+2-18)
= -1-(15-18)
= -1-(-3)
= -1+3

Find the measure of the angle indicated by 19x+5.
Answer:
100
Step-by-step explanation:
16x + 19x + 5 = 180 {co-interior angles are supplementary}
Combine like terms;
35x + 5 = 180
Subtract 5 from both sides
35x = 180 - 5
35x = 175
Divide both sides by 35
x = 175/35
x = 5
19x + 5 = 19*5 + 5
= 95 + 5
= 100
Answer:
100⁰
Step-by-step explanation:
co interior angles add up to 180⁰
so l9x+5+16x=180⁰
35x+5⁰=180⁰
35x=180⁰-5⁰
35x=175⁰
Divide both side by the co-efficient of x which is 35
35x/35=175⁰/35⁰
x=5
Now to find the value of 19x+5,we have to substitute any x in it by 5
so 19x+5
19(5)+5
95+5
100⁰

Answer: A.
Step-by-step explanation: There are a few outliers in A which would generally distort the shape of a dot plot where a majority would be clustered around the mean, and the points off to the side would fall far away from the mean making it skewed right in this situation.

Three teams, A, B and C, play in a competition.
games won by A: games won by B = 4:3
games won by B: games won by C = 5:2
Team B has won 30 games.
In total, how many games have the three teams won?
ANSWER:
43
Explanation:
A : B : C
4 : 3
5 : 2
A × B → 4 × 5 = 20
B × B → 3 × 5 = 15
B × C → 3 × 2 = 6
A : B : C
20 : 15 : 6
B = 15 = 30
what of teams A and C together?
If 15 = 30games, what about 26games?
Cross multiply.
15 × 26 =13
30
So, games won by Team B + games won by Teams A and C
30games + 13games
=43games.
Answer:
82
Step-by-step explanation:
find (x+55)°
find (3x-5)°
find x
Answer:
x = 30
Step-by-step explanation:
The two angles are congruent so they have the same value
3x-5 = x+55
Subtract x from each side
3x-5 -x = x+55-x
2x-5 = 55
Add 5 to each side
2x-5+5 = 55+5
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30
You would get
x=40

Simplify the expression -5+i/2i
Step by step
Answer:
For complex numbers,
a + bi and a - bi
they have the interesting property that if you add them you get the real number 2a
and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2
But since i^2 = -1, we end up with a real number as a product.
e.g. 6 - 5i and 6 + 5i are conjugates of each other
sum = 6-5i + 6+5i = 12
product = 36 - 25i^2
= 36 -(-25) = 61
Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i
Also I believe, according to the answer, that you have a typo, and you meant
(-5+i)/(2i)
= (-5+i)/(2i) *i/i
= (-5i + i^2)/2i^2)
= (-5i +i^2)/-2
= (-5i - 1)/-2
= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2

Step-by-step explanation:
The average rate of change of a continuous function,

Which is the required answer.
Additional Notes:
Note that this question is steered towards deriving the derivative
f
'

from first principles, as the definition of the derivative is:
f
'
(

=
lim
h
→
0
f
(
x
+
h
)
−
f
(

h
This is the function we had in [1], so as we take the limit as
h
→
0
we get the derivative
f

(

for any
x
, This:
f
