Step-by-step explanation:
Wich set of ordered pairs does not represent a function.
Please help.
Answer:
D.
Step-by-step explanation:
A function has to have only one y-value for every x-value. This means that D is not a function because it contains (6,2) and (6, 4), which means that there are 2 different y-values for the x-value of 6.

A woman is q years old while her son is p years old. the sum of their ages is equal to twice the difference of their ages. the product of their ages is 675.
write down the equations connecting their ages and solve the equations in order to find the ages of the woman and her son. WAEC
Step-by-step explanation:
Given
[tex]q + p = 2(q - p)[/tex]
as equation 1.
I used q-p as the difference as logically the woman will be older than her son.
Also given,
[tex]qp = 675[/tex]
as equation 2.
Using equation 2,
[tex]q = \frac{675}{p} [/tex]
substitute this equation into equation 1.
[tex] \frac{675}{p} + p = 2( \frac{675}{p} - p) \\ \frac{675}{p} + p = \frac{1350}{p} - 2p \\ \frac{675}{p} - \frac{1350}{p} = - 2p - p \\ - 3p = - \frac{675}{p} \\ - 3p \times p = - 675 \\ - 3 {p}^{2} = - 675 \\ {p}^{2} = - 675 \div - 3 \\ {p}^{2} = 225 \\ p = \sqrt{225} \\ = 15[/tex]
Substitute P into equation 2.
[tex]15q = 675 \\ q = 675 \div 15 \\ = 45[/tex]
Therefore the woman is 45 years old while her son is 15 years old.

10,20,40,80... find the common ratio for the geometric sequence
Answer:
2
Step-by-step explanation:
So the common ratio is simply what a number can be multiplyied by. To find this, all we have to do is see how many times one number goes into the one after it.
So lets take the 20(2nd number), lets divide it by 10(1st number). What do we get when we divide the numbers? We get 2. since 10 goes into 20, 2 times.
Lets see if the common ratio 2 checks out for the other numbers. What is 80(4th number) divided by 40(3rd number)? Well again, thats 2. Since 40 goes into 80, 2 times.
So, we can conclude that the answer is 2.
Answer:
I think the common ratio is 20
Step-by-step explanation:
Each number is 20 times the previous number, so the Common Ratio would have to be 10

Answer:
Ruffly 6.5
Step-by-step explanation:
a^2+b^2=C^2
In this case we need to find a so we do c^2-b^2.
9.8^2-7.3^2=42.75
Square root of 42.75 is ruffly 6.5
Answer:
6.5 km
Step-by-step explanation:
hypotenuse (h)=9.8km
base(b)=7.3km
perpendicular (p)=?
we know,
p^2 =h^2-b^2
p^2=(9.8)^2-(7.8)^2
p^2= 96.04-53.29
p^2=42.75
(p)^2=(6.5)^2
p=6.5km
The sales tax on clothing in Louisiana is 4% . Calculate how much tax you need to pay on a dress if it costs $19.50 before before tax. Round your answer to the nearest cent.
Answer:
.78 cents
Step-by-step explanation:
To find the tax amount on any number, divide that number by 100 and then multiple it by the tax percentage.
In this case that would look like: $19.50/100 times 4 =.78
Max has sticks of lengths 6, 7, 8, and 10 inches. He wants to make a right triangle for an art project. Which 3 sticks should he use? 6 in., 7 in., and 8 in. 6 in., 7 in., and 10 in. 6 in., 8 in., and 10 in. 7 in., 8 in., and 10 in.
Answer:
6in, 8in and 10in
Step-by-step explanation:
For a right angled triangle :
The hypotenus, thee longest side in The triangle should be :
Hypotenus = sqrt((opposite² + adjacent²))
The most appropriate from the option would be :
6in, 8in and 10in
Hypotenus = sqrt((6² + 8²))
Hypotenus = sqrt(36 + 64)
Hypotenus = sqrt(100)
Hypotenus = 10
Answer:
C. 6 in., 8 in., and 10 in.

A line passes through the point (-2,7) and has a slope of -5
Answer:
y - 7 = -5(x + 2) a = -1Step-by-step explanation:
The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = -5
(-2, 7) ⇒ x₁ = -2, y₁ = 7
y - 7 = -5(x - (-2))
y - 7 = -5(x + 2)
(a, 2) ⇒ 2 - 7 = -5(a + 2)
-5 = -5a - 10
5a = 5 - 10
5a = -5
a = -1
The average petrol consumption of a vehicle is 1 gallon per 35 km. The cost of 1 litre of petrol is $49. Fund the cost of petrol for a journey of 280 km.
(take 1 gallon=4.5 litres)
Step-by-step explanation:
Total petrol consumption of the journey=
Total distance travelled ÷ Average petrol consumption
[tex] = 280 \div 35 \\ = 8 \: gallons[/tex]
Given 1 gallon = 4.5 litres,
[tex]8 \: gallons \: = 8 \times 4.5 \\ = 36 \: litres[/tex]
Total cost of petrol for this particular journey = Petrol consumed x cost of 1 litre of petrol
[tex] = 4.5 \times 49 \\ = 220.50 \: dollars[/tex]
9. Find the value of x
Answer:
13 = x
Step-by-step explanation:
Remark
The six exterior angles add up to 360. In fact the exterior angles of any closed convex figure adds up to 360.
You can try this with simple figures. An equalateral triangle has 3 equal exteror angles. They are all 120 degrees 3*120 = 360
A square has 4 exterior angles. All 4 of them are 90 degrees. The sum of them is 90 * 4 = 360
Givens
Angles
3x+ 6,7x - 11, 62, 4x + 7 , 6x-5, 41The Total is 360 degrees
Solution
3x + 6 + 7x - 11 + 62 + 4x + 7 + 6x - 5 + 41 = 360 Combine like terms
20x + 100 = 360 Subtract 100 from both sides
20x = 360 - 100
20x = 260
x = 13
Check
3x + 6 = 457x - 11 = 80 624x + 7 = 596x - 5 = 73 41 Total 360Find the length of the hypotenuse?

Answer: x=22.0 (nearest tenth)
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos, Tan.
To which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin and then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos, then the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A' is for Opposite over Adjacent.
Because we have the Adjacent (angle next to 60°) and the Hypotenuse we would be using Cos.
So first you would write:
Cos 60=11/x
Then we would have to do the inverse to 'undo' the equation to get x on it's own. This would then look like:
x Cos 60=11
Then we do the inverse again:
x=11/Cos 60
so, x=22.0 (to the nearest tenth)
Hope this helps :)
I answered the question 3x-y=5 but is there a different way to answer this?
My answer:
I switched the y with the 3x
3x=y+5
Then I subtracted by 5
y=3x-5
Step-by-step explanation:
Hi,
I agree with what you did. You could also add y on both sides and get 3x = y + 5 and then divided by three to get...
x = 5 + y /3
(the 5 and y are being divided by 3)
But that's just complicated, it works, but it's complicated. What you did is correct and what I gave you is the value of x, but I'm 100 percent sure yours is correct.
Hope this helps
Answer and Step-by-step explanation:
Yes (technically), there is a different way to answer the equation 3x - y = 5. But, the first part of how you described it is a bit off.
Here is how you would explain it:
What you would do is Add y to both sides, then subtract 5 from both sides.
3x = y + 5
3x - 5 = y (aka y = 3x - 5)
The other way to solve:
3x - y = 5
Subtract 3x from both sides.
-y = -3x + 5
Now divide both sides by -1.
-1(-y) = -1(-3x + 5)
y = 3x - 5
If you want to solve for x, you would:
Add y to both sides of the equation.
3x = 5 + y
Then divide each side by 3.
x = [tex]\frac{1}{3}y[/tex] + [tex]\frac{5}{3}[/tex]

Hello! its 1
Step-by-step explanation:
A bag contains 3 red marbles and 4 blue marbles. A marble is taken at random from the bag and replaced. Another marble is taken from the bag.
Work out the probability that the two marbles taken from the bag are the same colour.
Give your answer as a fraction.
Answer:
25/49
Step-by-step explanation:
probability of red and red is (3/7)(3/7) = 9/49
Probability of blue and blue is (4/7)(4/7) = 16/49
Probability of same color = prob. of red and red or prob. of blue and blue
= 9/49 + 16/49
= 25/49
