x^{2}  - 7x +10 = 0

The middle term should be factored in such a way that the sum of two numbers is -7x and their product is 10x2. These two factors are -5x and -2x. So re-writing the equation, we get:

x^{2}  - 5x - 2x +10 = 0

Taking common, we get:

x( x - 5) -2 (x-5)=0 \\  \\ &#10;(x-5)(x-2)=0

This means:
x - 5 = 0
⇒ x = 5

or

x - 2 = 0
⇒ x = 2

Therefore, the solution to the given equation are x = 2 and x = 5

What is negative one eighth of a number is -3/4 as an equation?<br> will name the brainliest!
topjm [15]

Answer:

The equation is  -\frac{1}{8} x = -\frac{3}{4}

Step-by-step explanation:

The Equation is formed from two sides equal to each other

  • In the algebraic statement "is" means equal
  • In the algebraic statement "of" means times (×)

∵ One eighth means \frac{1}{8}

∴ Negative one eighth means  -\frac{1}{8}

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = -\frac{1}{8} × (x)

∴ Negative one eighth of a number = -\frac{1}{8} x

∵ Negative one eighth of a number is -\frac{3}{4}

→ "is" means equal, so the left side is -\frac{1}{8} x and the right side is -\frac{3}{4}

∴  -\frac{1}{8} x = -\frac{3}{4} ⇒ Equation

∴ The equation is  -\frac{1}{8} x = -\frac{3}{4}

PLEASE HELPO 25 POINTS
Grace [21]

Answer:

an = 1/2 (n) (n+1)

Step-by-step explanation:

1,3,6,10,.........

3-1=2

6-3=3

Each term is different so there is no common difference.  It is not an arithmetic sequence

3/1=3

6/3 =2

Each term is different so there is no common ratio.  It is not a geometric sequence

1       3            6        10

  +2          +3          +4


a1 = 1

a2  = 3

a3 = 6 = 2*3

a4 =  10 = 2*5

What would be the first step to this system of equations?
blagie [28]

The first step to apply using the elimination method is by multiplying the whole value of equation 1 by 3/2.

\begin{gathered} (2x+3y=5\text{ )}\times\frac{3}{2} \\ -3x+2y=-14 \\ 3x+\frac{9}{2}y=\frac{15}{2} \\ -3x+2y=-14 \\ \frac{9}{2}y+2y=\frac{15}{2}-14 \\ \frac{9y+4y}{2}=\frac{15-28}{2} \\ \frac{13y}{2}=\frac{-13}{2} \\ 26y=-26 \\ y=-1 \\ -3x+2(-1)=-14 \\ -3x-2=-14 \\ -3x=-14+2 \\ -3x=-12 \\ x=\frac{-12}{-3} \\ x=4 \end{gathered}
