X= -1/2, -11/2 or in decimal form x=-0.5, -5.5
givi [52]2 years ago
3 0

Answer:

  • <u>x = -0.5 , x = -5.5</u>

Step-by-step explanation:

<u>Solving</u>

  • -4x² = 24x + 11
  • 4x² + 24x + 11 = 0
  • 4x² + 24x + 36 - 36 + 11 = 0
  • (2x + 6)² - 25 = 0
  • (2x + 6)² = 25
  • ⇒ 2x + 6 = ±5

<u>Case 1 : x = +5</u>

  • 2x + 6 = 5
  • 2x = -1
  • x = -1/2
  • <u>x = -0.5</u>

<u></u>

<u>Case 2 : x = -5</u>

  • 2x + 6 =  -5
  • 2x = -11
  • x = -11/2
  • <u>x = -5.5</u>

Make the ratios equal. 9:25 = 36:?
satela [25.4K]

The equivalent ratio of 9:25 is 36:100.

Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.  

In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.

25 x 4 = 100

I need the answers to these if you can’t read it it says “You drink 16 Fluid ounces of milk for breakfast every morning”.
Reika [66]

Answer: A. y = 16 x

B. 8 days

Step-by-step explanation:

A) Here, 16 Fluid ounces of milk is used for breakfast every morning.

In one day the consumption of milk = 16 fluid ounces

In x days the consumption of milk = 16 x fluid ounces

Thus, if y be the total milk in ounces that is used in x days,

The required function,

y = 16 x

B)  In 1 day,  consumption of milk = 16 ounces

⇒ 16\text{ ounces milk } = 1 \text{ day}

⇒ 8\times 16\text{ ounces milk } = 8\times 1 \text{ day}

⇒ 128\text{ ounces milk } = 8 \text{ day}

Since, 128 ounces = 1 gallon

⇒ 1\text{ gallon milk } = 8 \text{ day}

In 8 days, 1 gallon of milk will consumed.
