If f(x) = х2 – 2x and g(x) = 6х +4, for which vаluе оf x does (f+g)(x) = 0?
x²+4x+4=0
(x+2)(x+2)=0
x= -2
f(g(x))=0
f(6x+4)=0
f(0)=0
x=-4/6
i did it in to step because i didnt understand what you mean we you write (f+g)(x)
but probably the first answer is the correct one
Answer:
x = - 2
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= x² - 2x + 6x + 4
= x² + 4x + 4
Then
x² + 4x + 4 = 0 ← in standard form
(x + 2)² = 0 ← in factored form
x + 2 = 0
x = - 2

point j'?
Answer:
J’ (-3,0)
Step-by-step explanation:
Right = x + 1 = -4 + 1 = -3

Answer:
Step-by-step explanation:
10). m(arc AB) = m(arc BC) = m(arc CA) [given in the picture]
m(arc AB) = [tex]\frac{360^0}{3}[/tex]
= 120°
Therefore, m(arc ACB) = m(arc AC) + m(arc BC)
= 120° + 120°
= 240°
11). m(arc CD) = 127° [Given]
m(arc AB) = 51° [Given]
m(arc AC) = m(arc BD) [Given]
m(arc CD) + m(arc BD) + m(arc AB) + m(arc AC) = 360°
127° + 2[m(arc BD)] + 51° = 360°
178° + 2[m(arc BD)] = 360°
2[m(arc BD)] = 360° - 178°
m(arc BD) = 91°
Since, m(arc CDB) = m(arc CD) + m(arc BD)
Therefore, m(arc CDB) = 127°+ 91°
= 218°
12). m(arc EH) + m(arc ED) + m(arc DH) = 360°
180° + 53° + m(arc DH) =360°
m(arc DH) = 360° - 233°
m(arc DH) = 127°

find the area of ABCD
trapezoid ABCD ~ trapezoid EFGH
trapezoid ABCD: 20cm
trapezoid EFGH: 5cm
area of EFGH = 40 sq cm
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²

The perimeter of a right -angled triangle is 72 cm . Its side are in the ratio 3 : 4: 5.Work out the longest length of the triangle.
Answer:
The longest length is 30 cm
Step-by-step explanation:
Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides
So, what we have to do here is divide the perimeter in the given ratio to get the side lengths
since 5 is the biggest of the numbers in the ratio, it represents the largest length value
so we have this as;
(3 + 4 + 5) = 12
So that would be;
5/12 * 72
= 5 * 6 = 30

A cash box contains a certain number of coins, of which 63 are dimes, 33 are nickels, and the rest are quarters. If the probability of selecting a quarter from this bank is 1 5, how many quarters does the bank contain
Answer:
There are 24 quarters in the cash box.
Step-by-step explanation:
Since a cash box contains a certain number of coins, of which 63 are dimes, 33 are nickels, and the rest are quarters, if the probability of selecting a quarter from this bank is 1/5, to determine how many quarters does the bank contain the following calculation must be performed:
1/5 = Quarters
4/5 = Nickels and Dimes
4/5 = 63 + 33 = 96
96/4 x 5 = X
24 x 5 = X
120 = X
120 - 96 = 24
Therefore, there are 24 quarters in the cash box.
A bag contains 10 blue marbles, 3 yellow marbles, and 12 orange marbles. If a blue marble is drawn you win $10. If a yellow marble is drawn you win $15. if an orange marble is drawn you lose $10. it cost $1 to play. Should you play the game?
Answer:
The correct option is -
Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.
Step-by-step explanation:
Given - A bag contains 10 blue marbles, 3 yellow marbles, and 12 orange marbles. If a blue marble is drawn you win $10. If a yellow marble is drawn you win $15. if an orange marble is drawn you lose $10. it cost $1 to play.
To find - Should you play the game?
Formula used -
Expected value , E[x] = ∑x p(x)
where p(x) is the probability.
Proof -
Given that,
Total blue marbles in a bag = 10
Total yellow marbles in a bag = 3
Total orange marbles in a bag = 12
So,
Total number of marbles in a bag = 10 + 3 + 12 = 25
Now,
Probability of getting blue marble = [tex]\frac{10}{25}[/tex]
Probability of getting yellow marble = [tex]\frac{3}{25}[/tex]
Probability of getting orange marble = [tex]\frac{12}{25}[/tex]
So,
Expected value , E[x] = ∑x p(x)
= (10)( [tex]\frac{10}{25}[/tex]) + (15)([tex]\frac{3}{25}[/tex]) + (-10)([tex]\frac{12}{25}[/tex])
= [tex]\frac{100}{25} + \frac{45}{25} - \frac{120}{25}[/tex]
= [tex]\frac{100 + 45 - 120}{25}[/tex]
= [tex]\frac{25}{25}[/tex]
= 1
So,
Expected value = 1
So,
The correct option is -
Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.

PLEASE HELP!!!
Answer:
The correct selections are A and B.
Step-by-step explanation:
The picture depicted above can be represented as [tex]5w+4=99[/tex], since 5 times something plus 4 is the same as 99. In choice a, Andre babysat 5 times and earned the same amount of money each time, so you could represent that by [tex]5w[/tex]. Since he received an extra $4 and earned a total of 99 dollars, the first choice is correct. In choice B, the family of 5 paid the same amount for each ticket, which can be represented by [tex]5w[/tex]. Since they paid $4 for parking and paid a total of $99, choice B can also be represented by the picture, which means it's correct.
