<u>Part 1)</u> we have
------> equation A
------> equation B
Substitute the equation B in equation A
Find the value of x
the best approximation is the point
therefore
<u>the answer Part 1) is the option C</u>
<u>Part 2) </u>we have
------> equation A
------> equation B
equate equation A and equation B
Find the value of y
the solution is the point
therefore
<u>the answer Part 2) is </u>
Answer:
Step-by-step explanation:
To find (c.g)(x) we basically use the function d(x) as your variable, x, and plug it into c(x). So we replace every x in c(x) with the function d(x),
c(g(x))=4(x^{2} +5x)-2
c(g(x))4+20x-2
Answer:
9,700,000.
Explain:
9 goes in the 1,000,000th place, and 700 would be placed right behind the 9's comma. Therefore, 9,700,000
4(x + 9) + 5x = 9x - 36
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true.
So there is no solution for this equation.
Answer is C. no real solutions
Answer:
$20.15
Step-by-step explanation:
Given data
Original cost = $9.57
Markup= 95%
Let us find the new cost of the basket
=95/100*9.57
=0.95*9.57
=$9.0915
Hence the cost of the basket is
= 9.57+9.0915
=18.66
Also, the sales tax is 8%
=8/100*18.66
=0.08*18.66
=1.4928
Therefore, the total amount to be paid is
=18.66+1.4928
=$20.15
