Answer:

Step-by-step explanation:

this is a simultaneous equation question

f(1)=8  so  a(1) + b = 8

f(4)=17 so a(4) + b = 17

can you figure this out from here ???

if you can't below is how to solve it

a + b = 8

4a+b=17

multiply the top equation by 4 and then subtract the bottom one from the top

4a+4b = 32

-(4a +b = 17)

3b = 15

b=5

now plug 5 into the first equation

a + 5 = 8

a=3

there you go :)

:)))) solve the following by factorizing: x^2-2x=120
stepladder [879]

Answer:

Step-by-step explanation:

x^2 - 2x = 120\\x^2 - 2x - 120 = 0

We have to find the factors of 120 that can either add up to or have a difference of 2.

The factors of 120 are:

\pm 1, 120, 2, 60, 3, 40, 4, 30, 5, 44, 6, 20, 8, 15, 10, 12...

The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:

(x+10)(x-12)
