The simplified expression is 8x - 3

7 - 1x - 1(-5x) - 10 + 4x
7 + (-1x) + (5x) + (-10) + 4x
7 + (-10) + (-1x) + 5x + 4x
-3 + 8x
8x - 3

p is inversely proportional to 3q-1. The difference in the values of p when q = 1 and q=2 respectively is 3. Find the value of p
Vsevolod [243]

Step-by-step explanation:

3q - 1 = 3(1) - 1 = 2

3q -1 = 3(2)- 1= 5

10/p = 2 10/p = 5

p= 5 p= 2 (5-2=3, so 10/p is correct)

q=5, 3(5) -1 = 14

10/p = 14

p = 0.71??

3. What is f(2) if f(x) = 2x³ - 19x² +28x + 47?<br> O 45<br> O 40<br> O 43<br> O 37
Lesechka [4]

Answer: C: 43

Step-by-step explanation:

As we are calling the function with 2 for x, we can substitute 2 for every x we see in the function and solve.

f(2)=2(2)^3-19(2)^2+28(2)+47\\=2(8)-19(4)+28(2)+47\\=16-76+56+47\\=43

Hence, f(2) is 43.

2x - 2y

Step-by-step explanation:

P = 7x + 2y

P =a + b + c

7x + 2y = 2x + y +3x - 5y + c

7x + 2y - 5x - 4y

= 2x - 2y
