3 1/2 * 6 1/2
3 1/2 to improper fraction = (3*2 + 1) / 2 = 7/2
6 1/2 to improper fraction = (6*2 + 1) / 2 = 13/2
3 1/2 * 6 1/2 = 7/2 * 13 /2 = 91 / 4
91 / 4
= 22 3 /4 square unit
Answer:
number o students bought pennants = 18
number of student bought fancy ones=12
Step-by-step explanation:
Let x be the number o students bought pennants
and y be the number of student bought fancy ones
total 30 students
Plain pennants cost $4 each and fancy ones cost $8 each.
Substitute 30-x for y in second equation
Subtract 240 from both sides
divide both sides by -4
x=18
number o students bought pennants = 18
number of student bought fancy ones=12
Answer:
(9,9)
Step-by-step explanation:
All you have to do is look down and across to the numbers. If you need help with the x and y here it is (x,y)
here is a trick to remember it "run x before you fly to y "
Answer:
Step-by-step explanation:
The one-to-one functions g and h are defined as follows.
g={(-7,-6), (-5,4), (4,-7)(7,6)}
h(x)= 3x-14
Find the following.
g-1(4)=
"g-1(4)" just says "Find the pair of coordinates that has 4 for its
y-coordinate, and the answer is its x-coordinate". So we look through those
and find (-5,4) is the only one of those up there that has a 4 for it's y-
coordinate, and so its x-coordinate is -5 and we write:
g-1(4)=-5
Answer:
(6x^4-7)(6x^4+7)
Step-by-step explanation:
36x^8-49
1. look for a gcf. since there isn't one, you move on to the next step.
2. what multiplies to what you need. you can do box method or diamond method.
3. (6x^4-7)(6x^4+7)
