X - - 3 = 10 <br><br> What is the value of x?
Pepsi [2]

Answer:

x = 7

Step-by-step explanation:

Rule: an even number of - signs written one after another produces a plus number.

So - - 3 = 3

The rule also lets you do something strange like

- - - - 4 = 4 but you hardly ever see this.

Rule: an odd number of minus signs produces a minus number.

x + 3 = 10                 Subtract 3 from both sides.

x + 3 - 3 = 10 - 3      

x = 7

Write the quadratic equation whose roots are 1 and −5, and whose leading coefficient is 4.
jarptica [38.1K]

Answer:

Standard Form: y = 4(x-1)(x+5)

Step-by-step explanation:

4 is the leading coefficient, so it should go in front. When making a standard quadratic equation, you must do the opposite for each of the roots (negative to positive, positive to negative.)

if you’re asking for a general form quadratic equation, then sorry, I am unable to help you with that :(

What is the value of b2 - 4ac for the following equation? 2x 2 - 2x - 1 = 0
Orlov [11]
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides. 

<span>2x^2 + 3x + 0=0 </span>

<span>a=2, b=3, c=0 </span>

<span>b^2-4ac (In the next step just plug in your variables) </span>

<span>3^2 - 4(2)(0) </span>

<span>9 - 8(0) </span>

<span>9 - 0 </span>

A soldier started patrolling around his camp at 22 30 . His patrol lasted 3 hours and 20 minutes .What time did his patrol end
baherus [9]

Answer:01 50 Hrs

Step-by-step explanation:

If the soldier started patrol at 2230 hrs and his petrol lasted for 3 hours and 20 minutes, that means he was on patrol for that time.

The time he finished was therefore:

= 2230 + 320

= 2550

At 24 you begin at 0:00am so:

= 2550 - 2400

= 150

Patrol ended at 0150 hrs
