Diagram is attached. No, the relation is not a function.
In order for a relation to be a function, each input value must be mapped to no more than 1 output value. One of our input values, -2, is mapped to 2 output values (-1 and 0). Therefore this is not a function.
Answer:
a number that is substituted in an inequality that makes the inequality a true statement.
EXAMPLE :
x + 2 < 7 ; x= 4
1) substitute 4 into the inequality
4 + 2 < 7
2) solve ( add 4 and 2 together )
6 < 7
the number 4 is a solution to the inequality because 6 < 7 is true.
Answer:
(-4+3, -3) = (-1,-3)
Step-by-step explanation:
You need one equation of this problem to balance the amount of a boric acid.
The amount of boric acid in 50% solution is expressed as 0.50*x
Next, the amount of water is taken from 25 liters and x (based on 50% solution), that is 25 - x. However, there is NO amount of BORIC ACID in water, and that is 0.
For the output solution, the amount of boric acid will be 0.10*2.5 = 2.5
Then, the balance equation is
0.50*x + 0*(25 - x) = 2.5
Solving for x,
0.50*x + 0 = 2.5
x = 2.5/0.5 = 5
Therefore the amount of liters in 50% solution is
5*0.50 = 2.5 liters
The amount of water is 25 - 5 = 20 liters
Answer:
The pre-tax price of "smart fabric" warm-ups is $745 .
Step-by-step explanation:
Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .
As given
arold paid 5% in sales tax on his new "smart fabric" warm-ups.
if harnold paid 37.25 in sales tax on the warm ups .
5% is written in the decimal form .
= 0.05
Equations becomes
0.05 × x = 37.25
0.05x = 37.25
x = $745
Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
