What is the equation of the line, in slope-intercept form, that passes through (3, -1) and (-1, 5)? y = -3/2x+7/2 2y = -3x + 7 2

SOVA2 [1]

Answer:

The equation of the line would be y = -3/2x + 7/2

Step-by-step explanation:

In order to find this, we must first use the slope formula with the two point to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - -1)/(-1 - 3)

m = 6/-4

m = -3/2

Now that we have the slope, we can use that and either point in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y + 1 = -3/2(x - 3)

y + 1 = -3/2x + 9/2

y = -3/2x + 7/2

the sum of the measures of the interior angels of a convex polygon is 3240 classify the polygon by the number of sides

Ipatiy [6.2K]

Answer:

20-gon

Step-by-step explanation:

First we start with the formula to find what the sum of angles will be if we know the number of sides.

S=(n-2)*180 where S is the sum of angles and n is the number of sides.

Normally you'd plug in n to find S, but you can do the opposite too.

3240=(n-2)*180

Let me know if you need help working it from here.

Which of the following is the rational exponent expression of third root of 4 n? A) (4n)3

zhuklara [117]

You have to check which of the following expressions is the rational exponent expression of third root of 4n, or mathematically, $\sqrt[3]{4n} .$ Consider all cases:

A. $(4n)^3=4^3\cdot n^3=64n^3\neq\sqrt[3]{4n} .$

B. $3n^4\neq \sqrt[3]{4n} .$

C. quantity of 4n to the one third power is $(4n)^{\frac{1}{3} }=\sqrt[3]{4n}$ (by the definition of rational power).

D. 4 times n to the one third power is $4\cdot n^{\frac{1}{3} }=4\sqrt[3]{n}\neq \sqrt[3]{4n} .$

Answer: correct choice is C.
