Applies distributive property
5x + 20 - 5 = 3x -18 + 1
combines like terms
5x + 15 = 3x - 17
subtraction properties of equality
2x + 15 = -17
subtraction properties of equality
2x = -32

coefficients: 2 and -32

answer
first one -32 and 2

A customer placed an order for muffins.The Baker has completed 37.5% of the order after baking 81 muffins. How many muffins did

IceJOKER [234]

81 divided by 37.5 equals 2.16, 2.16 would be equivalent to 1% so to find 100% we simbly multiply 2.16 by 100, 2.16 multiplied by 100 equates to 216, so the Baker is making 216 muffins.

If this is a word problem, put it into your own words in case of getting in trouble.

I hope this helped, have an awesome day!!

What to do if quadratic equation has a negative spuare root?

alex41 [277]

If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be $3+\sqrt{5}$

then $3-\sqrt{5}$ will also be a solution.

Divide 12x 4 y 4 by 3x 2 y. A. 4x 6y 5 B. 4x 2y 3 C. 9x 6 D. 9x 2y 3

andrew-mc [135]

Answer:

$\frac{12x^4y^4}{3x^2y}=4x^2y^3$

Step-by-step explanation:

Consider an element $a\neq 0$

We know that $\frac{a^m}{a^n}=a^{m-n}$

Here, m and n are exponents and a is a base. Exponent refers to the no. of times a term is multiplied by itself. Another word for exponents is powers.

Other Properties of exponents:

$a^m\times a^n=a^{m+n}\\a^0=1\\\left ( a^m \right )^n=a^{mn}$

Here, we are required to divide $12x^4y^4$ by $3x^2y$ .

Consider $\frac{12x^4y^4}{3x^2y}$

We will solve $\frac{12}{3}\,,\,\frac{x^4}{x^2}\,,\,\frac{y^4}{y}$ separately.

Here,

$\frac{12}{3}=4\\\frac{x^4}{x^2}=x^{4-2}=x^2\\\frac{y^4}{y}=y^3$

So, $\frac{12x^4y^4}{3x^2y}=4x^2y^3$

How do you Graph y=-3/5x+6

dangina [55]

Let's pick two points on the line, the y-intercept, and the x-intercept. These are the points at which x=0, and y=0.

When x=0:
$y=-3/5x+6
\\y=-3/5(0)+6
\\y=6$

So one point is (0,6)

When y=0:
$y=-3/5x+6
\\0=-3/5x+6
\\-6=-3/5x
\\-30=-3x
\\x=10$

So another point is (10,0)

So mark the points (0,6) and (10,0) on a pair of axes, and draw a straight line between them, and past them to infinity. This is a graphing of the line y=-3/5 x + 6
