Solve the equation. Write the smaller value of x. x^2-4x-5=0

1 answer:

3 0

X^2 - 4x - 5 = 0
(x-5)(x+1) = 0
x = 5
x = -1

x = 5 OR x = -1

since it says write the smaller value, then i think the answer is -1.

Y = mx + c
y = 2x + c
When x = 5 and y = 0,
0 = 2(5) + c
c = -10

y = 2x - 10

Answer:

Step-by-step explanation:

-4(2z+6)-12 = 4

=> -8z - 24 - 12 = 4

=> -8z = 4 + 12 + 24

=> -8z = 40

$= > z = \frac{40}{ - 8}$

=> z = - 5 (Ans)

Answer:

x= 0

Step-by-step explanation:

Here in this question, we are given a linear equation of single variable x, and we have to solve the equation for x.

The given equation is 9x -7= -7 ....... (1)

Now, taking all the constant terms to the right side of the equation and all the x terms to the left side of the equation.

Hence, the equation becomes

9x = -7 +7

⇒ 9x =0 {Since, -7 and 7 cancels each other}

⇒ x= 0/9= 0 (Answer) {Since zero divided by any number is equal to zero}
