theres another unanswered question on my profile also those also give 14 points
PLEASEE i will give brainliest

For this case, the first thing we must do is define variables.

We have then:

t: cost of the torch

b: cost of the battery

The cost of both items in £ is given by:

Therefore, we have the following equation:

Then, we know that:

The torch costs eleven times as much as the battery.

Substituting equation two in the equation we have:

Clearing the value of b we have:

The cost of the battery is 0.43 £

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
