You can use the substitution method. Using the first equation in terms of y,
y = 5 - x
Substitute this to the second equation to get the value of x.
x - 2(5 - x) = 2
x - 10 + 2x = 2
3x = 2 + 10
3x = 12
x = 4
For y, just substitute the value of x that we have used in the first equation.
y = 5 - 4 = 1
Therefore, in coordinate form, that is (4,1)
Answer:
C, D and E
Step-by-step explanation:
Assuming
f(x) = √(9−8x)
and the options are:
A. p(x) = √(-8x) and q(x)=9+x
B. p(x) = √(9+x) and q(x)=8x
C. p(x) = √(-x) and q(x)=8x−9
D. p(x)=√(9−x) and q(x)=8x
E. p(x)=√x and q(x)=9−8x
F. p(x)=9−8x and q(x)=√x
G. All of the above
H. None of the above
Substituting in f(x)=p(q(x)) we get:
A. √(-8(9+x)) = √(-72 - 8x)
B. √(9+(8x)) = √(9+8x)
C. √(-(8x−9
)) = √(-8x + 9)
D. √(9−(8x)) = √(9−8x)
E. √(9−8x
)
F. 9−8(√x
) = 9 - 8√x
Answer:
YES!!!!
Step-by-step explanation:
if the numerator is odd then and not able to be divided evenly into 2 whole numbers then your fraction is in its simplist form!
Answer:
no
22.25 minutes
Step-by-step explanation:
First determine how long it will take her to read the entire book
20 pages 47 pages
-------------- = ----------------
35 minutes x minutes
Using cross products
20x = 35*47
20x=1645
Divide by 20
20x/20 = 1645/20
x =82.25 minutes
This is more than 1 hour ( 1 hour = 60 minutes)
82.25 minutes - 60 minutes = 22.25 minutes
She will need 22.25 more minutes
Answer:
The Correct answer would be option D, $16,000.
Step-by-step explanation:
Look at the bottom section of the graph, that is labled
"Age (in years)" at the number 4 line (representing the 4 year old car), and find the nearest dot on that line of the graph, it goes directly to 16,000.
