\sf Hello!

\sf y = 2x^{2} + 4x - 3

\sf Discriminant :

= \sf b^{2} - 4ac

= \sf (4)^{2} - 4.(2).(-3)

= \sf 16 - (-24)

= \sf 16 + 24 = \sf 40

\sf Since,
\sf D \:is\:Greater\: than\: 0.

\sf Roots\: are\: Real\: and\: Distinct

\sf Hence,

\sf y = 2x^{2} + 4x - 3\: have\: A.\: Two\: real\: roots

Hey there!

Guide ⬇️

• Cup: is a cooking measurement for volume, it very much common in sizes & cooking things.

• Tablespoon: a abundant (huge) sized spoon that’s used for serving.

• Liter: is the limitation of volume that is held which is balanced (equal to) to ONE cubic decimeter.

• Fluid ounce: is basically unit space that is held at 1/16th of a US pint.

Based on that information the one that seems closer to the RIGHT answer is:

[Option A. Cup]

[Option B Tablespoon]

[Option D. Fluid Ounce]

Random fact:

• [1 (US) CUP] is approximately [8 (US) OUNCE]

• [1 (US) TABLESPOON] is approximately [1/2 (or 0.5)(US) US OUNCE)

• [1 FLUID OUNCE] is approximately [28.35 GRAM]

Good luck on your assignment and enjoy your day!

10. Write the slope-intercept form of the equation of the
Ghella [55]

Answer:

y = -3x + 18

Step-by-step explanation:

The slope intercept form of a line is expressed as y = mx+c

m is the slope

b is the intercept

Get the slope

Given the equation of a line 9x + 3y = 6

Rewrite

3y = -9x + 6

y = -9x/3 + 6/3

y = -3x + 2

Hence the slope of the line is -3

Get the y-intercept

Substitute m = -3 and (5,3) into y  = mx+b

3 = -3(5) + b

3 = -15 + b

3 + 15 = b

18 = b

b = 18

Get the required equation

y = mx+b

y = -3x + 18

This gives the required equation

Your softball team is selling candles to raise money for a trip. For each candle you sell, $5.50 goes towards your trip. You hop
andriy [413]

20 or more candles must be sold to reach the goal.

Step-by-step explanation:

Given,

Each candle contributes = $5.50

x be the number of candles.

Amount needs to be earned = $110 or more

Therefore,

According to given statement;

5.50x ≥ 110

\frac{5.50x}{5.50}\geq \frac{110}{5.50}\\x\geq 20

20 or more candles must be sold to reach the goal.
