Answer:
The answer to your question is below
Step-by-step explanation:
f(x) = 2x + 5
To solve letter a, just multiply each term of f(x) by 3 and subtract 2.
a) 3f(x) - 2 = 3(2x + 5) - 2
= 6x + 15 - 2
= 6x + 13
To f(x) subtract twice g(x)
b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)
= 2x + 5 - 2x² + 6x - 4
= -2x² + 8x + 1
Multiply 5 by each term of f(x) and divide it by g(x)
c) 
= 
Answer:
A ≈ 158.37km²
Step-by-step explanation:
<u>Using the formulas</u>
A=πr2
d=2r
<u>Solving forA</u>
A = 1
/4πd 2
= 1
/4·π·
14.22 ≈ 158.36769km²
Therefore, the are of the circle in nearest hundredth is A ≈ 158.37km²
Reciprocal is basically just swapping them around, so for 10/3 it's 3/10 and that's your answer!
Complete question :
Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars. write an expression that represents how much money gary will have left over after the purchase then simplify your expression
Answer:
$(16x - 1)
Step-by-step explanation:
Given that:
Amount Gary has = $(20x + 7)
Price per pair of jeans = $(2x - 3)
Number of pairs = 2
Cost of 2 Jean pairs = 2 * $(2x - 3) = $(4x - 6)
Amount left after purchase :
$(20x - 7) - $(4x - 6)
20x - 7 - 4x + 6
20x - 4x - 7 + 6
$(16x - 1)
