Use the zero product property to find the solutions to the equation 2x2 + x - 1 = 2

Firdavs [7]

Answer:

Step-by-step explanation:

Given

2x² + x - 1 = 2 ( subtract 2 from both sides )

2x² + x - 3 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 3 = - 6 and sum = + 1

The factors are - 2 and + 3

Use these factors to split the x- term

2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )

2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(2x + 3) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - $\frac{3}{2}$

Find the percent of increase or decrease? 2.5y to 1.5y

horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value = Initial value - Final Value

= 2.5 y = 1.5 y = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

$\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y} \times 100 = 40$

or, Percentage Decrease = 40%

Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.

If the smallest angle of a triangle is 20° and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest

lawyer [7]

Answer:

$3.5$

Step-by-step explanation:

The smallest side of a triangle is formed by the smallest angle in the triangle.

To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, $c^2=a^2+b^2-ab\cos \gamma$ , where $a$ , $b$ , and $c$ are the three sides of the triangle and $\gamma$ is the angle opposite to $c$ .
