Answer:
-1 < x < 2
Step-by-step explanation:
The graph indicates the variable may take on values between -1 and 2, not including those values. The compound inequality is written ...
-1 < x < 2
Answer:
y =24
Step-by-step explanation:
very simple and direct, just combine the like terms and subtract 3 from 27
and that is the value of your y.
solution
3 + y = 27
y = 27 -3
y =24
Answer:
An infinite number of solutions
Step-by-step explanation:
This is because of all the 0's the zeros represent none and none is infinite. When in the matrix you are solving and solving is a infinite. When times 0 is 0 and when divided by 0 is infinite so an infinite amount of answers.
Answer:
The rope is worth 13.
The shoe is worth 5.
The clock is worth 3.
Step-by-step explanation:
We know that the weights are 8 so we will use 8 for the weights.
Let s = show
Let r = rope
Let c = clock
We have three unknowns so we need three equations.
8 + s = r c + s = 8 s= c +2
There are a number of ways that we can approach this. Let's substitute
c + 2 for s in the first 2 equations.
8 + s = r
8 + c + 2 = r
10 + c = r
c + s = 8
c + c + 2 = 8
2c + 2 = 8
2c = 6
c = 3 we found the value of the clock.
Now, let's substitute 3 in for 3 in the bold equation above.
10 + c = r
10 + 3 = r
13 = r we found the value of the rope.
We can use any of the equations to find the shoe.
s= c + 2
s = 3 + 2
s = 5
This is tricky. It takes a lot of practice. Don't give up!
answer:use the given functions to set up and simplify f (7).
f (-5)= 17
f (7)=19
Hope this helps :)
