Step-by-step explanation:
Answer:
11= EC
Step-by-step explanation:
EC = 10 + 2 x + 19
= x + 20
So 2 x + 29 - x - 20 = 0
so x + 9 = 0
x = -9.
EC = x + 20 = -9+20 = 11.
Answer:
Step-by-step explanation:
10 + 2x + 19 = x + 20
2x - x = 20 - 10 - 19
x = -9
--------------------------------
check
10 + 2(-9) + 19 = -9 + 20
10 - 18 + 19 = -9 + 20
11 = 11
same value the answer is good
EC = 10 + 2x + 19
EC = 10 + 2(-9) + 19 (remember PEMDAS)
EC = 10 - 18 + 19
EC = 11 units
Step-by-step explanation:
Speed is independent and distance is dependent
Distance depends on the speed
Speed influences the distance
From the information given, the original price per pound was increased by $ 0.75
Let the original price be x, so the new price is x + 0.75
Sam bought 3 pounds of apples at new price and it cost him 5.88
so we form an equation:
3 (x + 0.75) = 5.88
3x + 2.25 = 5.88
3x = 5.88 - 2.25
3x = 3.63
x = 3.63 / 3
x = 1.21
Therefore the original price per pound is 1.21 dollars
Answer:
1.21=x
Step-by-step explanation:
Do
3 (x + 0.75) = 5.88
then 3x + 2.25 = 5.88
then 3x = 5.88 - 2.25
to 3x = 3.63
and last of allx = 3.63 / 3

The compositefunction gof (x) is 4x^2 + 2.
The correct option is b.
Let the two functions f(x) and g(x) generate a new function h(x) using an operation.
The operation is a composition of functions and h(x) is a compositefunction.
Given:
Three functions f(x) = 2x, g(x) = x² + 2, and h(x) = -4x + 3.
To find the compositefunction gof (x), we need to substitute g(x) into f(x) wherever there is an x in f(x).
gof (x) = g(f(x))
= g(2x)
= (2x)²+ 2
= 4x² + 2
Therefore, gof (x) = 4x² + 2.
