A man borrowed $8000. He paid $10100 after 9 months for the debt. What was the interest rate per annum?

Anastaziya [24]

Answer:

3.5%

Step-by-step explanation:

Interest = 10100 - 8000 or 2100

I = Prt

2100 = 8000(9/12)r

2100 = 600r

2100/600 = r

3.5 = r

Factor 4x^4yz-16y^3z

Iteru [2.4K]

Answer:

<h2>4x⁴yz - 16y³z = 4yz(x² - 2y)(x² + 2y)</h2>

Step-by-step explanation:

$4x^4yz-16y^3z\\\\4x^4yz=4yz\cdot x^4\\\\16y^3z=4yz\cdot4y^2\\\\4x^4yz-16y^3z=4yz\cdot x^4-4yz\cdot4y^2=4yz(x^4-4y^2)\\\\x^4-4y^2=x^{2\cdot2}-2^2y^2=(x^2)^2-(2y)^2=(x^2-2y)(x^2+2y)\\\\Used:\\\\(a^n)^m=a^{nm}\\\\(ab)^n=a^nb^n\\\\a^2-b^2=(a-b)(a+b)\\\\4x^4yz-16y^3z=4yz(x^2-2y)(x^2+2y)$

Given the equation 8x=4Y +16 ,generate a plan to rewrite it in slope-intercept form WHICH VARIABLE DO YOU SOLVE FOR?

andriy [413]

Answer:

you switch 8x and 4y by subtracting 8x to 4y + 16 and substracting 4y to 8x.

This gives you the equation -4y = -8x+16

Then you divide each side by -4

To give you your slope-intercept form which is y = 2x-4.
