What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7

tia_tia [17]

The given equation is

$3x+5y=7$

Consider the slope-intercept form.

$y=mx+b$

Rewriting the given equation in the slope-intercept form.

$3x+5y=7$

Subtracting 3x from both sides, we get

$3x+5y-3x=7-3x$

Dividing both sides by 5, we get

$\frac{5y}{5}=\frac{7-3x}{5}$ $y=-\frac{3}{5}x+\frac{7}{5}$

$y=-0.6x+1.4$

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.

Combine the terms in the given polynomial then evaluate for x=3, and y=-1

Novay_Z [31]

Answer: $xy^2+3x^2y;\text{ -24}$

Explanation:

The given expression is:

$xy+3xy^2-2xy+3x^2y-2xy^2+xy$

Combine like terms

$xy+xy-2xy+3xy^2-2xy^2+3x^2y$

Simplify the resulting expression

$\begin{gathered} 2xy-2xy+3xy^2-2xy^2+3x^2y \\ \\ xy^2+3x^2y \end{gathered}$

Substitute x = 3 and y = -1 into the simplified expression

$\begin{gathered} xy^2+3x^2y \\ \\ 3(-1)^2+3(3)^2(-1) \\ \\ 3(1)+(-27) \\ \\ 3-27 \\ \\ =-24 \end{gathered}$

A fair six-sided die is rolled. Find the probability of getting a 4.

madam [21]

Answer:

A fair six-sized die is rolled. Find the probability of getting at least a 4.

There are 6 outcomes and three of them are 4, 5 or 6, so the probability of greater than or equal to 4 is 3/6=½.

What are the factors of 3x²+7x-20?

Leya [2.2K]

$3x^2+7x-20=0\\\\a=3;\ b=7;\ c=-20\\\\\Delta=b^2-4ac\\\\x_1=\frac{-b-\sqrt\Delta}{2a};\ x_2=\frac{-b+\sqrt\Delta}{2a}\\\\\Delta=7^2-4\cdot3\cdot(-20)=49+240=289;\ \sqrt\Delta=\sqrt{289}=17\\\\x_1=\frac{-7-17}{2\cdot3}=\frac{-24}{6}=-4;\ x_2=\frac{-7+17}{2\cdot3}=\frac{10}{6}=\frac{5}{3}\\\\\\3x^2+7x-20=3(x+4)(x-\frac{5}{3})\\\\\\3x^2+7x-20=0\iff x=-4\ \vee\ x=\frac{5}{3}$
