The table and the graph show information about students enrolled in spanish and french classes at a high school. use the graph to determine after how many years there will be equal enrollment in spanish and french classes
Answer:
after 6 years
Step-by-step explanation:
thats when the lines intersect, (6,300)
There will be equal enrollment in Spanish and French classes after 6 years from now.
The red line shows the number of students enrolled in French class each year from now and blue line shows the number of students enrolled in Spanish class each year from now.
The point of intersection of the lines is the point which lies in both the line.
So, it represents the point or time when there are same number of students enrolled in both French and Spanish classes.
From the graph, we can see that the two lines at a point [tex](6,300)[/tex]. The value on the [tex]x[/tex]-coordinate shows the years from now. So, we can say that there will be equal number of students enrolled in two classes after 6 years.

Factorise 3x²+5x-12
Show working out
hi <3
i'm not sure of which method you will have been taught but i'll try to explain the method i was shown.
so, you need to multiply the coefficient of x^2 by the last value
3 x -12 = -36
now, you need to find two values that multiply to make -36 but add to make 5.
9 and 4 would work. it would have to be positive 9 and negative 4, as these would subtract to give the 5 that you need
now we have:
(x - 4)(x + 9)
however, we need to achieve the 3 from somewhere so it needs to be divided somewhere
9 is divisible by 3 so you can divide it there. as 4 cannot divide by 3, you would move the 3 up to be the coefficient.
thus, your final answer would be:
(3x - 4)(x + 3)
hope this helps :)

Question 1
Find(f+g)(x)
f(x)=4x−4 and g(x)=2x^2−3x
Question 2
Find(f−g)(x)
f(x)=2x^2−2 and g(x)=4x+1
Question 3
Find(h⋅g)(x)
h(x)=3x−3 and g(x)=x^2+3
Question 4
Find(f/g)(x)and state the domain restriction.
f(x)=x+4 and g(x)=x+6
Step-by-step explanation:
Q1 . (f+g)(x) = f(x) + g(x)
=4x-4 +2x^2 -3x
= 2x^2 + x -4
Q2. (f-g)(x) = f(x) - g(x)
= 2x^2−2 - (4x+1)
= 2x^2 -2 -4x -1
= 2x^2 - 4x -3
Q3. h(x)=3x−3 and g(x)=x^2+3
(h.g)(x) = h(x) × g(x)
= (3x-3) × (x^2 + 3)
=3x^3 -3x^2 + 9x -9
Q4.f(x)=x+4 and g(x)=x+6
(f/g)(x) = f(x) ÷ g(x)
= x+4 / x+6
the domain restriction is x>-6
x<-6
x doesn't equal (-6)
If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,
(f + g)(x) = f(x) + g(x)
(f - g)(x) = f(x) - g(x)
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
(f . g)(x) = f(x) × g(x)
Question 1
f(x) = 4x - 4 and g(x) = 2x² - 3x
[tex](f+g)(x)=f(x)+g(x)[/tex]
Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]
[tex]=2x^2+x-4[/tex]
Question 2
f(x) = 2x² - 2 and g(x) = 4x + 1
Since, (f - g)(x) = f(x) - g(x)
Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)
= 2x² - 2 - 4x - 1
= 2x² - 4x - 3
Question 3
h(x) = 3x - 3 and g(x) = x² + 3
Since, (h - g)(x) = h(x) - g(x)
Therefore, (h - g)(x) = (3x - 3) - (x² + 3)
= 3x - 3 - x² - 3
= -x² + 3x - 6
Question 4
F(x) = x + 4 and g(x) = x + 6
Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]

Hitler purchased a watch for Rs. 3500 and sold it to Alex at 5% loss. Find her loss amount and the price at which she sold the watch
Answer:
Loss Amount: 175; Price: 3325
Step-by-step explanation:
You can multiply 3500 by 0.05 (which is 5% in decimal) to find how much is the loss. Then, you subtract the loss from the base price to find the new price.
Answer:
Loss =175, sold = 3325
Step-by-step explanation:
He bough at 3500
So 100 percent is 3500
And they said he had a 5% loss
So in other words, he sold it to Alex at 95% of the price he bought
So
3500 x 95%
3500 x 95/100
=3325
This is the price when Hitler sold it to alex
Now how much did Hitler lose?
3500 - 3325
=175

Answer:
you would need 12 gallons of water.
Step-by-step explanation:
The ratio is 4 : 1/3. This means that for every 1/3 cups of cleaner, there is 4 gallons of water.
This in mind, 3 1/3 cups of cleaner would be 1/3 x 3.
Whatever you do to one side, you have to do to the other.
4 gallons x 3 = 12.

Step-by-step explanation:
The canidate won, so that means that they were the 7 instead of the 5.
Then you divide 20734 by 7, to see how many votes were for each "1". That's 2962.
Now you know that every "1" is worth 2962. Since the other candidate got 5, you multiply 5 by 2962 which is 14810.
The other candidate got 14810 votes.

I really need help with this math problem and please explain (-1) + (-2 2/5) =
Answer: -3 2/5
Step-by-step explanation:
When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.
1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.
solve the equation simultaneously:
y = 2-2x
y = -16 + 2(x-3)^2
Answer:
y = -26
Step-by-step explanation:
[y = 2 - 2x] + [y = -16 + 2(x - 3)^2]
y = -16 + 2x - 6^2
y = -16 + 2x - 6^2 + 2 - 2x
y = (+2x - 2x) - 16 - 6^2 + 2
y = -16 - 6^2 + 2
y = -16 - 12 + 2
y = - 28 + 2
y = -26

A and Z are both between points M and N such that MZ=AN and A is between M and Z. Given: MA=5x AZ=3x-2 AN=6(2x-1) find MN
Answer:
MN = 11
Step-by-step explanation:
M___A___Z___N
MZ =MA+AZ
MZ = 5x + 3x -2 = 8x - 2
MZ = AN
8x - 2 = 6(2x-1)
8x - 2 = 12x - 6
12x - 8x = 6 -2
4x = 4
x =4/4
x =1
MA= 5x = 5(1) = 5
AZ = 3x-2 = 3(1) - 2 = 3 -2= 1
MZ = 8x -2 = 8(1)-2= 8-2=6
AN = 12x - 6 = 12(1)-6 = 12 - 6 = 6
MN = MA + AN = 5 + 6 = 11

A store has a sale with 30% off every item. When you enter the store, you receive a coupon that states that you receive an additional 30% off. Is this equal to a
60% discount? Explain your answer.
Answer:
No, It is not equal to a 60% discount.
Step-by-step explanation:
Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.
