Isaiah determined that 5a^2 is the GCF of the polynomial a^3 - 25a^2b^5 - 35b^4. Is he correct? Explain

Answers

Answer 1

Answer: The answer is no, he did not arrive with the correct answer. With Isaiah claiming that 5a^2 is the GCF of the polynomial a^3 - 25a^2b^5 - 35b^4, he is incorrect because the constant '5' does not apply to the first factor of the equation which is 'a^3'.

Answer 2

Answer:

Answer:

No, Isiah is not correct. The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial. 5b4 is a factor of -25a2b5 and -35b4, but not a3. Additionally, a2 is a factor of a3 and -25a2b5, but not -35b4.

What are the values of x in the equation x(x-6)=4(x+6)

Answers

x(x-6)=4(x+6)

Multiply out:

x² - 6x = 4x + 24

x² - 6x - 4x - 24 = 0

x² - 10x - 24 = 0

This is a quadratic equation

x² - 10x - 24 = 0 Divide through by 2

Multiply first and last coefficients: 1*-24 = -24

We look for two numbers that multiply to give -24, and add to give -10

Those two numbers are -12 and 2.

Check: -12*2 = -24 2 + -12 = -10

We replace the middle term of -10x in the quadratic expression with 2x -12x

x² - 10x - 24 = 0

x² + 2x - 12x - 24 = 0

x(x + 2) - 12(x + 2) = 0

(x + 2)(x - 12) = 0

x + 2 = 0 or x - 12 = 0

x = 0 -2 x = 0 + 12

x = -2 x = 12

The solutions are x = -2 or 12

Line JK passes through points J(–3, 11) and K(1, –3). What is the equation of line JK in standard form?

Answers

Answer:

7x+2y =1

Step-by-step explanation:

Hello

use the points to find the slope (A)

$A=(-3-11)/(1-(-3)) \nA= (-14)/(4) \n\n\nA=-(7)/(2) \n\n\n$

with the slope and a point , let´s take J(-3,11)

$y-y_(0) = A (x-x_(0) )\n\ny-11=-(7)/(2) (x+3)\ny-11=-(7x)/(2) -(21)/(2) \ny+(7x)/(2) =-(21)/(2) +11\n\ny+(7x)/(2) =0.5\n\n\n$

must be multiplied by two to eliminate the fractional and then order

$2*(y+(7x)/(2)) =2*0.5\n7x+2y =1$

y-11=-7/2(x+3) is one answer and y+3=-7/2(x-1) is the other
