Answer:

There are three terms on the expression(3x, -5y, 3)

Step-by-step explanation:

The first step to solve this question is adding or subtracting all the common factors.

After that, each value that is added or subtracted is a term. So

2x - 5y + 3 + x = 3x - 5y + 3

There are three terms on the expression(3x, -5y, 3)

Hi there, it's really not 4 terms it actually 3 terms, I will explain why. If you combine the 2x with the x that would give you 3 terms, not 4 terms. So, there are 3 terms in it, you have to make sure to simplify it.

lex is saving money because she would like to purchase the new video gaming system that everyone has been talking about. After t

spin [16.1K]

Well one week she'd have 23.50$. So per week you multiply that number by the number of weeks.

I hope this is what you were looking for, the question was a bit confusing.

How many solutions does the system have? y=-2x -4 y=3x + 3

baherus [9]

Answer:

x=−7/5and y=−6/5

Step-by-step explanation:

Step: Substitute−2x−4foryiny=3x+3:

y=3x+3

−2x−4=3x+3

−2x−4+−3x=3x+3+−3x(Add -3x to both sides)

−5x−4=3

−5x−4+4=3+4(Add 4 to both sides)

−5x=7

−5x

−5

(Divide both sides by -5)

x=−7/5

Answer:

$\sf x=1+i\sqrt{\dfrac{2}{3}} \ \quad and \quad \:x=1-i\sqrt{\dfrac{2}{3}}$

Explanation:

Given Expression:

3x² - 6x + 5 = 0

Use the Quadratic Formula:

$\sf x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \ \ when \ \ ax^2 + bx + c = 0$

insert coefficients

$\Longrightarrow \sf x = \dfrac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:3\cdot \:5}}{2\cdot \:3}$

$\Longrightarrow \sf x = \dfrac{\left6\right\pm \sqrt{-24} }{6}$

$\Longrightarrow \sf x = \dfrac{\left6\right\pm 2\sqrt{6}i}{6}$

$\Longrightarrow \sf x =1 \pm i\dfrac{\sqrt{6} }{3}$

$\Longrightarrow \sf x=1+i\sqrt{\dfrac{2}{3}}, \quad 1-i\sqrt{\dfrac{2}{3}}$
