Answer:
f(4) = 1
Step-by-step explanation:
f(4) = what?
So if we know that x, aka 4, is technicially f is greater then 2, so you can plug in x as 4. So that means 5(4) - 19 = 20 - 19 = 1, so f(4) = 1
Answer:
x=10
Step-by-step explanation:
5/8x - 11/2 = 3/4
Multiply each side by 8 to clear the fractions
8(5/8x - 11/2 = 3/4)
5x - 44 = 6
Add 44 to each side
5x-44+4= 6+4
5x= 50
Divide by 5
5x/5 = 50/5
x =10
Answer:
6
Step-by-step explanation:
Straight line is 180
square = right angle=90
180-90=90
5x+(x+54)=90
6x+54=90
6x=36
x=6
Hope this helps :D
Multiply the two brackets together
(2x-1)(x-2)
2x(x)(2x*-2)(-1*x)(-1*-2)
2x^2-4x-x+2
2x^2-5x+2
Answer is 2x^2-5x+2 - J
