Answer:
The two numbers are -4 and -10.
Step-by-step explanation:
x+y=-14
x-y=6
----------
2x=-8
x=-8/2
x=-4
-4+y=-14
y=-14-(-4)=-14+4=-10
x=-4, y=-10.
Given:
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair is in the function , then .
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
Therefore, the value of f(2) is 3 and the value of f(5) is 6.
Answer:
Choice D
Step-by-step explanation:
(9.1 x 10^5) - (9.3 x 10^4)
910000 - 93000 = 817,000 = 8.17 x 10^5
usually, you would want <u>a whole number</u> in standard notation
A. 0.817 x 10^6 = 817,000
B. 817 x 10^3 = 817,000
C. 8.17 x 10^4 = 81,700
D. 8.17 x 10^5 = 817,000
ensure all fractions have the same denominator
we require - = -
thus - - -
take out a common factor
= (- 7 - 4 - 5 )
= × - 16 = - 1
This is the concept of business mathematics, given an inflation rate of 3%, that has modeled the price of items using the function c(x)=1.03x, the cost of the refrigerator in 3 years will be as follows;
cost after 1 year:
c(1)=1.03*1500
=1545
cost after 2 years
c(2)=1.03*1545
=1591.35
the cost after 3 years will be:
c(3)=1.03*1591.35
=$1,639.09
