How do I order 4,pi,and the square root of 8

nevsk [136]

2/3x - 1/2y = 3 |multiply both sides by 6

4x - 3y = 18

1/2x + y = 5 |multiply both sides by 2

x + 2y = 10

Answer: 4x - 3y and x + 2y = 10.

Write an equation of a line in slope intercept form (y = mx + b) going through the points

Alexeev081 [22]

Answer:

y = - $\frac{1}{2}$ x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (4, - 3)

m = $\frac{-3-0}{4+2}$ = $\frac{-3}{6}$ = - $\frac{1}{2}$ , thus

y = - $\frac{1}{2}$ x + b ← is the partial equation

To find b substitute either of the 2 points into the partial equation

Using (- 2, 0 ), then

0 = 1 + b ⇒ b = 0 - 1 = - 1

y = - $\frac{1}{2}$ x - 1 ← in slope- intercept form

Eva8 [605]

If you want to earn more points, you can answer question that are worth more points. Others ways are you can complete a challenge on Brainly and receive those extra points. Get on the leaderboard and receive extra points daily, weekly, and monthly for 1st, 2nd, and 3rd place Or become a site Moderator and earn 5 points for each moderation performed. Also by choosing a Brainliest answer for the question you ask and receive 25% of the total points you will assigned to the question.

Hope this helped you- have a good day bro cya)

Simplify the fraction and state the excluded value(s).

stira [4]

Answer:

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10} = \frac{7x - 10}{5}, x \neq -2$

Discontinuities

Removable (Holes)
Jump (Piece-wise functions)
Infinite (Asymptotes)

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10}$

Step 2: Simplify

[Frac - Numerator] Factor quadratic: $\displaystyle \frac{(7x - 10)(x + 2)}{5x + 10}$
[Frac - Denominator] Factor GCF: $\displaystyle \frac{(7x - 10)(x + 2)}{5(x + 2)}$
[Frac] Divide/Simplify: $\displaystyle \frac{(7x - 10)}{5}, x \neq -2$

When we divide (x + 2), we would have a removable discontinuity. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.

2x^2 + 9x +12+3x+2 8x^2 write an equivalent expression.

Alex73 [517]

Answer:

10x^2 + 12x + 14

Step-by-step explanation:

Combine like terms: 2x^2 + 8x^2 = 10x^2 , 9x + 3x = 12x , 12 + 2 = 14

In total: 10x^2 + 12x + 14
