The answer is £2.80. To find the cost of 1 pen, you divide £4 (all 10 pens) by 10 which gives you 40p. To find 7 pens, you multiply 40p (1 pen) by 7. £0.40 x 7 = £2.80

Well, the first thing we need to do is divide 10 by 4. These teo numbers are the number of pens, and cost of them. So,
================================
10 / 4 = 2.5
--------------------------------------------------------
Now we have to use the answer we got, 2.5 which is the cost of 1 pen, and multiply it by 7.
================================
2.5 x 7 = 17.5
--------------------------------------------------------
This means that 7 pens cost <span>£</span>17.5

Help me find the range of this function please
lara31 [8.8K]

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

f(x)=-2x-18

f(-8)=-2(-8)-18

f(-8)=16-18

f(-8)=-2

The first value of the range of the function is -2

- For x = -2

f(x)=-2x-18

f(-2)=-2(-2)-18

f(-2)=4-18

f(-2)=-14

The second value of the range is -14

- For x = 4

f(x)=-2x-18

f(4)=-2(4)-18

f(4)=-8-18

f(4)=-26

Th third values of the range is -26

- For x = 16

f(x)=-2x-18

f(16)=-2(16)-18

f(16)=-32-18

f(16)=-50

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}
