I hope im right!!
Answer:
25 percent
Step-by-step explanation:
£40 is the old price and £50 is the new price. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old price.

f(x)= 2x +6 , vertical shrink by a factor of 1/2
Answer:
g(x) = x+3.
Step-by-step explanation:
i hope this helps :D
When a function is shrunk vertically, the function has undergone a form of transformation.
The resulting function when [tex]f(x) = 2x + 6[/tex] vertically shrink by 1/2 is [tex]f'(x) = x + 3[/tex]
Given that:
[tex]f(x) = 2x + 6[/tex]
[tex]k = \frac 12[/tex] --- shrink factor
When a function is shrunk vertically, the rule of transformation is:
[tex](x,y) \to (x,ky)[/tex]
So, we have:
[tex]f'(x) = k f(x)[/tex]
The new function becomes
[tex]f'(x) = \frac 12 \times (2x + 6)[/tex]
[tex]f'(x) = x + 3[/tex]
Hence, when [tex]f(x) = 2x + 6[/tex] is vertically shrunk by 1/2, the new function is [tex]f'(x) = x + 3[/tex]

D) F
The expression that will be an integer when it is evaluated is given by:
B) H.
Which expression is always an integer value?When two integers are multiplied, the result is always an integer.
In this problem, expression H has the multiplication of two integers, 9 and -3, hence option B is correct.
The other expressions have rationals involved in the multiplication, hence the result of the expression will be a rational.

find an expression for the nth term -3 , 2 , 7, 12
Answer:
5n-8
Step-by-step explanation:
Because this is an arithmetic progression, there is simply an addend that is being added to every number. Because that is 5, the expression, for now, would be 5n. However, the progression does not start at 0, so we will have to subtract 3, and then it would be 5n - 3. We're still not at the answer; this is because the first term starts at 1, not 0. We will have to account for that, so subtract the coefficient, or 5, from the whole expression. That would be 5n - 8, and that would be the answer.

0.2(3k+1)=-0.4-(-0.2-0.1K)
Answer:
k=−0.8
Step-by-step explanation:
Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)
Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)
(0.2)(3k) + (0.2)(1) = 0.6k + 0.2
(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k
New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k
Now we can combine like terms on the right side. (-0.4 and 0.2)
0.6k + 0.2 = 0.1k - 0.2
Now to get rid of k on one side, we can subtract 0.1k from the right side.
(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2
0.5k + 0.2 = -0.2
Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.
0.5k + (0.2 - 0.2) = (-0.2 - 0.2)
0.5k = -0.4
To get k by itself, we must divide both sides by 0.5.
(0.5k / 0.5) = (-0.4 / 0.5)
k = -0.8
Solve 2x + 20 = 6x – 12*
Answer:
x = 8
Step-by-step explanation:
Given
2x + 20 = 6x - 12 ( subtract 2x from both sides )
20 = 4x - 12 ( add 12 to both sides )
32 = 4x ( divide both sides by 4 )
8 = x
=> 2x + 20 = 6x - 12
=> 20 + 12 = 6x - 2x
=> 32 = 4x
=> x =32/4
=> x = 8What are rational numbers? Why is it important to study rational numbers?
Answer:
Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)
