What is the value of the second one in 15.186

answer:

step-by-step explanation:

let travis' age be a.

so,

substitute a= 2b-62 in a + b=70. so, a in a+b becomes 2b-62

2b-62+ b can be rewritten as 2b+b-62   which is also 3b-62

so, this equation (2b-62+ b=70) becomes 3b-62=70

3b-62=70 ⇒ 3b=70+62 ⇒ 3b=132

b=132/3

b=44

but remember

now you know b, you can find a

a= 70-b

a=70-44

a=26

big boi's 44 years old, travis is 26

you can also check by plugging the values in the second equation

2(44) - 62 is 26

answer:

f(x) = 3(x+2)(x-2)

step-by-step explanation:

we are given a quadratic function and we have to write it in factored form

f(x) = 3x² - 12

we can take 3 common above

f(x) = 3 ( x² - 4 )

f(x) = 3( x² - 2²)

using formula (a²-b²) = (a+b)(a-b)

f(x) = 3(x+2)(x-2)

it would be y=3 because if you flip the line of y=-3 over thex-axis, you would get this
