To solve this equation, the first thing to do would be to simplify. Look at the steps shown below.

-\frac{1}{2}x + 1 = 7x - 14

(To make things easier, I will be writing 1/2x as 0.5x)

First isolate x my moving the variables to one side of the equation and the numbers to the other. Please note that when you move them this way, the number or variable must become the opposite of what it currently is for the equation to remain true. The equation will now look like;

-0.5x - 7x = -1 - 14

--> -7.5x = -15

We know that 2 * 7 is 14. Since we have two hales, this creates a whole.

--->x = \frac{15}{7.5}

---->x = 2

The answer is A.

Alvin throws the football to a receiver who jumps up to catch the ball. The height of the ball over time can be represented by t
Mandarinka [93]

Answer:

The standard form of the equation is 49t² - 75t + 3 = 0

The solution of the equations are 1.49 and 0.041

Step-by-step explanation:

* Lets explain how to solve the problem

- The standard form of the quadratic equation is ax² + bx + c  = 0,

  where a , b , c are constant and a can not be 0

∵ The quadratic equation is -4.9t² + 7.5t + 1.8 = 2.1

- Lets make the left hand side equal to 0

∵ -4.9t² + 7.5t + 1.8 = 2.1 ⇒ subtract 2.1 from both sides

∴ -4.9t² + 7.5t - 0.3 = 0 ⇒ multiply each term by -10

∴ 49t² - 75t + 3 = 0

* The standard form of the equation is 49t² - 75t + 3 = 0

∵ ax² + bx + c = 0

∴ a = 49 , b = -75 , c = 3

- Lets use the formula x=\frac{-b+-\sqrt{b^{2}-4ac}}{2a} to solve

 the equation

∴ x=\frac{-(-75)+\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=1.49

∴ x=\frac{-(-75)-\sqrt{(-75)^{2}-4(49)(3)}}{2(49)}=0.041

* The solution of the equations are 1.49 and 0.041
