Answer:
f(3) = -11
Step-by-step explanation:
f(x) = -3x-2
let x=3 and replace it in the above equation
f(3) = -3(3) -2
f(3) = -9 -2
f(3) = -11
-16 = 8x/5......8x/5 is the same as 8/5(x)
-16 = (8/5)x...divide both sides by 8/5
-16 / (8/5) = x
-16 * 5/8 = x
-80/8 = x
-10 = x <===
The numbers that can be expressed in the form of a fraction are called rational numbers. While that numbers that cannot be expressed in the form of a fraction are called irrational numbers.
is an irrational number, it cannot be expressed in the form of a fraction.
Step-by-step explanation:
as just answered in the other question, the y-intercept is simply the y-value, when x=0.
it is -5 for function 1.
and function 2 clearly crosses the y-axis at y = -7, which is the y-intercept.
as -5 is greater than -7, function 1 had the greater y- intercept.
Ahhh I think that is cheating?
Soz I know the anaswer but I cant tell you have to do by your self to learn you can't always ask for answers :<
