If a+b=50

When b=30

a=50-b

a= 50 - 30

a=20

Therefore 20(a)+30(b)=50

Evan graphed a cubic function, f(x) = ax3 + bx2 + cx + d, and determined the roots of f(x) to be +1 and 2. What is the value of

Lana71 [14]

The value of $b$ in the <em>cubic</em> polynomial is -4.

<h3>How to determine the coefficients of a cubic polynomial</h3>

After a quick analysis, we find that given <em>cubic</em> function is equivalent to the following equivalence:

$x^{3}+b\cdot x^{2}+c\cdot x + d = (x-1)^{2}\cdot (x-2)$

$x^{3}+b\cdot x^{2}+c\cdot x + d = (x^{2}-2\cdot x + 1)\cdot (x-2)$

$x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-2\cdot x^{2}+x-2\cdot x^{2}+4\cdot x-2$

$x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-4\cdot x^{2}+5\cdot x -2$

After a quick observation, we conclude that the value of $b$ in the <em>cubic</em> polynomial is -4. $\blacksquare$

Write the equation in standard form.<br><br> 8−5y=−2x

GarryVolchara [31]

8-5y= -2x
⇒ -5y= -2x-8
⇒ y= -2/(-5)x -8/(-5)
⇒ y= 2/5x+ 8/5

The final answer is y= 2/5x+ 8/5~
