Answer:
-5/9
Step-by-step explanation:
[tex]\frac{5}{9}[/tex] + ____ = 0
subtract [tex]\frac{5}{9}[/tex] from both sides of the equation
-[tex]\frac{5}{9}[/tex] -[tex]\frac{5}{9}[/tex]

I would like help on this math problem please!
Answer:
4^11
Step-by-step explanation:
[(4^3)(4^4)]÷(4^1+4^-4)
using laws of indices
(4^3)(4^4)=4^(3+4)
=4^7
(4^1 +4^-4)=4^(1-4)
=4^-3
4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal
4^7/4^-3=4^(7-(-3)
=4^(7+3)
=4^11
A 26 foot ladder is set against the side of a house so that it reaches up 24 feet. If Mila
grabs the ladder at its base and pulls it 12 feet farther from the house, how far up the side of the house will the ladder reach now?
Answer:
13.9
Step-by-step explanation:
13.85 feet far up the side of the house will the ladder reach now.
Given that, a 26 feet ladder is set against the side of a house so that it reaches up 24 feet.
What is heights and distances in trigonometry?In mathematics, you can calculate the height of an object using the distance and angles. Here distance is the horizontal distance between the object and the angle is the angle above the horizontal of the top of the object, which gives the height of the object.
Let the distance between base of house to foot of the ladder be x.
Using Pythagoras theorem 26²=24²+x²
⇒ 676 = 576 + x²
⇒ x² = 100
⇒ x =10 feet
Mila grabs the ladder at its base and pulls it 12 feet farther from the house.
Now, the distance between base of house to foot of the ladder = x+12
= 10+12 = 22 feet.
So, up the side of the house the ladder reach = 24-h
Then, 26² = (24-h)²+22²
⇒ 676 = (24-h)²+484
⇒ (24-h)² = 192
⇒ (24-h) = √192
⇒ (24-h) = 13.85
⇒ h = 24-13.85
⇒ h = 10.15 feet
Therefore, 13.85 feet far up the side of the house will the ladder reach now.

One card is drawn from a standard 52-card deck and then replaced, and then a second
card is drawn. What is the probability that the first card is a red 8 and the second is a
black 10?
Answer:
1/676
Step-by-step explanation:
In a deck of cards there are 2 red 8's ( 8 of diamonds and 8 of hearts)
P( red 8) = number of red 8's/ total
= 2/52 = 1/26
Then we put the card back so there are still 52 cards
In a deck of cards there are 2 black 10's ( 10 of spades and 10 of clubs)
P( black) = number of black 10's/ total
= 2/52 = 1/26
Multiply the probabilities together
P( red 8, black 10) = 1/26 * 1/26 = 1 /676
X - 2y = -3
2x + y = -1
Answer:
y = 1
x = -1
Step-by-step explanation:
x - 2y = -3, then x = 2y - 3
2x + y = -1
substitute for x:
2(2y - 3) + y = -1
4y - 6 + y = -1
5y = 5
y = 1
x = 2 - 3 = -1
Answer:
it can only be simp[lified
so it will be

If using the method of completing the square to solve the quadratic equation
x² + 2x + 16 = 0, which number would have to be added to "complete the
square"?
Answer:
x=-1+\sqrt{15}i,\:x=-1-\sqrt{15}i
Step-by-step explanation:
For the given quadratic equation,x² + 2x + 16 = 0 the value of x will be x=-1+√15i, and x-=-1-√15i you must add 1 in order to complete the square.
What is a quadratic equation?Any equation with the formula [tex]\rm ax2 + bx + c = 0[/tex] where x is a variable and a, b, and c are any real values; a quadratic equation is one where a ≠ 0.
It is given that the equation is, x² + 2x + 16 = 0,
The value of x obtained after solving the given equation is x=-1+√15i and x-=-1-√15i.
In order to complete the square you have to take out the following operations,
x² + 2x + 16 = 0
Add and subtract by 1 as
x²+2x+16+1-1
x²+2x+1 +15
(x+1)²+(√15)²
Thus, you must add 1 in order to complete the square.

Annie earns $15 per hour babysitting. How many hours will it take her to earn $60?
Answer:
4 hours
Step-by-step explanation:
15 x 4 = 60
$60
Answer:
4 hours.
Step-by-step explanation:
We are looking for the amount of money Annie will need to earn 60.
Let the equation be 15+x=60.
The equation could be represented as 15+x=60, or 60-15=x.
The easier solution would be to subtract.
When we subtract 60-15 we get 45, therefore the value of x is 45 making the statements true.
15+45=60 and 60-15=45 as well.
We know she earns 15 an hour, so we have to see how many 15 we can add up to get to 60.
15+15+15+15=60, therefore she will need to work 4 hours.

To make a jug of plant fertilizer, Malaika uses 6 cups of water and 3 scoops of fertilizer. Bart uses 8 cups of water and 5 scoops of fertilizer. Will Malaika's and Bart's plant fertilizer have the same strength? Explain.
Answer:
No they will no have the same strength. So what I did was find a common number between them so between 8 and 6 they both can be multiplied to 24. So 6 goes into 24 4 times so I multiplied 3 times 6 and then 8 goes into 24 3 times so I multiplied 3 and 5 and so the final answer is that bart has more strong fertilizer
Step-by-step explanation:
6*4=24 4*3=12
8*3=24 5*3=15
