Answer: 2 and 7/12
Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.
Notice however that we can't subtract 0/12 - 5/12.
So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.
Now we have 3 and 12/12 - 1 and 5/12.
Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.
So 5 - 1 and 5/12 is 2 and 7/12.
Answer:x>1
Step-by-step explanation:
Subract 11 from both sides
Answer:
Let's solve for x.
−2(x+3y)=18
Step 1: Add 6y to both sides.
−2x−6y+6y=18+6y
−2x=6y+18
Step 2: Divide both sides by -2.
−2x/−2
=
6y+18
−2
x=−3y−9
Answer:
−3y−9
For f(x)=ax²+bx+c
if a is positive, then it is concave up and the verx is minimum
if a is ngative then it is concave down and vertex is maximum
hack: in form f(x)=ax²+bx+c, the x value of vertex is -b/2a
to find y value, just subsitutte that value for x in f(x)
so
y=-1x²+4x-4
negative, so vertx is max
x value of vertex is -4/(2*-1)=-4/-2=2
find f(2) or subsitute 2 for x
y=-1(2)²+4(2)-4
y=-1(4)+8-4
y=-4+4
y=0
maximum is 0
