Answer: replace f(x) with y

.

y=x2+x−30

To find the roots of the equation, replace y

with 0

and solve.

0=x2+x−30

Rewrite the equation as x2+x−30=0

x2+x−30=0

Factor x2+x−30

using the AC method.

(x−5)(x+6)=0

Set x−5

equal to 0 and solve for x


x=5

Set x+6

equal to 0 and solve for x

x=−6

The solution is the result of x−5=0

and x+6=0


x=5,−6

Hope this helps!

Neporo4naja [7]

Answer:

y = 10

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{y}{20} = \frac{1}{2} ( cross- multiply )

2y = 20 ( divide both sides by 2 )

y = 10

Answer:

The full question is attached in the picture below.

The better price for the battery is given with the 6 pack.

(£ 0.47 per battery)

Step-by-step explanation:

If 8 batteries cost £ 3.99

This means that one battery is equal to

£3.99/8 = £ 0.49875 ≈ £ 0.50 per battery

The pack of 6 batteries costs £ 2.79
