What is the solution for 1/2+x=5/4

Mathematics
1 answer:
prohojiy [21]3 years ago
7 0
<span>1/2-(5/4) = x+1/4 // - x+1/4

1/2-x-(5/4)-(1/4) = 0

1/2-x-5/4-1/4 = 0

-x-1 = 0 // + 1

-x = 1 // * -1

x = -1

x = -1

Given that f(–2.4) = -1 and f(-1.9) = -8, approximate<br> f'(-2.4).<br> f'(-2.4)
lora16 [44]

Answer:

f'(-2.4) ≈ -14

General Formulas and Concepts:
<u>Algebra I</u>

Coordinate Planes

  • Coordinates (x, y)

Slope Formula: \displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}

Functions

  • Function Notation

<u>Calculus</u>

Differentiation

  • Derivatives
  • Derivative Notation

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the <em>tangent</em> <em>line</em>.

<u>Step 1: Define</u>

<em>Identify.</em>

f(-2.4) = -1

f(-1.9) = -8

<u>Step 2: Differentiate</u>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.

  1. [Derivative] Set up [Slope Formula]:                                                           \displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}
  2. Substitute in coordinates:                                                                           \displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}
  3. Evaluate:                                                                                                       \displaystyle f'(-2.4) \approx -14

I’ll 40 points for these answers, thank you
attashe74 [19]
1. 24%
2. 13%
3. 60%


1. Since 6/25 is .24, 24% of the class was absent
2. He spent 3 hours in total.. Divide is by 24 because there are 24 hours in a day. 3/24 is 0.125 for 13% of the day
3. He ran 3 of the 5 miles, so 3/5 = 0.6.. meaning 60%. The time doesn’t matter

What is the greatest common factor of 40 and 36
Kazeer [188]

Nobody goes around with lists of greatest common factors in their head. 
When we need to know one, we grab the nearest pencil and work it out.

The factors of  40  are  1,  2,  4,  5,  8,  10,  20, and  40 .

The factors of  36  are  1,  2,  3,  4,  6,  9,  12,  18, and  36 .

The common factors of  35  and  40  are  1,  2, and  4 .

The biggest one is  4 .
