Solve the system of equations algebraically

statuscvo [17]

Answer:

y = x^2 + 8x + 16

y = x + 6

x^2 + 8x + 16 = x + 6

x^2 + 7x + 10= 0

(x + 5)(x+2) = 0

x = -5

x = -2

y = (-5)^2 + 8(-5) + 16

y = 25 - 40 + 16

y = 41 - 40

y = 1

y = -5 + 6= 1

y= (-2)^2 + 8(-2) + 16

y = 4 - 16 + 16 = 4 + 0 = 4

y = -2 + 6 = 4

Point of intersection: (-2, 4)

Answer:

$2c - 3$

Step-by-step explanation:

$3c - \frac{1}{3} = \frac{c}{2} = 2c - \frac{1}{3} (2) = 2c - \frac{2}{6} = 2c - 3$

PLEASE HELP!

Answer:

7 percent

Step-by-step explanation:

We have the following information from the question:

The probability that a student chooses art as an elective is 15 percent: $P(A)=15\%$

The probability that a student chooses art or drama is 20 percent: $P(A\cup D)=20\%$

The probability that a student chooses both art and drama is 2 percent:

$P(A\cap D)=2\%$

Recall that:

$P(A\cup D)=P(A)+P(D)-P(A\cap D)$

We plug in the various probabilities to get:

$20\%=15\%+P(D)-2\%$

$20\%-15\%+2\%=P(D)$

$7\%=P(D)$

$\therefore P(D)=7\%$

Hence the probability that a student chooses drama as an elective is 7 percent

Answer:

Polynomial

$x^4 +3x^3 -5x^2 -7x +20\\\\x^3 -2x^2 +x -12\\\\x^2 + 3x^5 -6x +12x^3$

not a polynomial

$4\sqrt[3]{x} -\sqrt{x} -20\\\\x^{-3}-x}^{-2}-6x^{-1}+8\\\\\frac{5}{x^3} -\frac{1}{x^2} +\frac{8}{x} -40\\\\$
