Tell of the solution to the following equation. Explain your answer. 4(x + 3) - 4 = 8x + 10 - 4x
Solve the equation:
5 + 4x - 7 = 4x - 3-X
Answer:
1 = -x
Step-by-step explanation:
group like terms together so
this 5 + 4x - 7 = 4x -3 - x
becomes this 5 - 7 + 3 = 4x -4x -x
then simplify 1 = - x

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

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.
The sum of 48 and itself,it's half and half of the half is added to 18

Answer:
(-2, 3)
Step-by-step explanation:
For x-4 you go left four places and y+6 go up 6 places
Answer:
(-2, 3)
Step-by-step explanation:
Point P has coordinates (2, -3).
The translation is (x - 4, y + 6) which means subtract 4 from the x-coordinate and add 6 to the y-coordinate.
The x-coordinate of point P is 2. Subtract 4 from it, you get -2.
The y-coordinate of point P is -3. Add 6 to it to get 3.
The coordinates of the translated point are (-2, 3).

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]

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

This ratio would be 12:1
Step-by-step explanation:
There's 12 gallons of water to 1 cup of cleaner.
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.

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.

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 :)
