Hi there!
To find f(1), plug in x=1 into the equation
f(1) = -4(1) + 7
= -4 + 7
= 3
That's your answer.
Have an awesome day! :)

Answer:
x-12=24, x=36
Step-by-step explanation:
letter X subtract 12 is 24. Add 12 to both sides, and x=36.

<span> 2.1 </span> Subtracting a fraction from a whole
Rewrite the whole as a fraction using <span> <span>x2</span> </span> as the denominator :
<span> x2 + x (x2 + x) • x2
x2 + x = —————— = —————————————
1 x2

<span>Equivalent fraction : </span>The fraction thus generated looks different but has the same value as the whole
<span>Common denominator : </span>The equivalent fraction and the other fraction involved in the calculation share the same denominator
<span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> x2 + x</span> = x • (x + 1)
Adding fractions that have a common denominator :
<span> 3.2 </span> Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
<span> x • (x+1) • x2 - (6) x4 + x3 - 6
———————————————————— = ———————————

<span> 4.1 </span> Adding a whole to a fraction
Rewrite the whole as a fraction using <span> <span>x2</span> </span> as the denominator :
<span> 6x 6x • x2
6x = —— = ———————
