Answer:

one solution: x=10

Step-by-step explanation:

The coefficients of x on each side of the equal sign are different, so the equation is not a tautology. It must have exactly one solution.

F(x) = x2 – 2x - 8

maw [93]

Answer:

The y-intercept is the point (0,-8)

see the attached figure

Step-by-step explanation:

we have

$f(x)=x^{2}-2x-8$

we know that

The y-intercept is the value of the function f(x) when the value of x is equal to zero

For x=0

$f(x)=0^{2}-2(0)-8\\f(x)=-8$

therefore

The y-intercept is the point (0,-8)

Answer:

Estimate the value of pi =3.14

Step-by-step explanation:

The diameter of the circle base of a storage container 18.8m

The diameter of the circle 'd' = 2r

Given data 'd' = 2r = 18.8m

The circumference of the circle = 2πr

Given data of circumference of the circle = 59 m

given 2πr = 59

2r(π) = 59

18.8 π = 59 ( by using 2r =18.8)

π = 59/18.8

π = 3.13829

π = 3.14

Conclusion:-

Estimate the value of pi =3.14

Answer:

$(x + 5) \times (x + 2)$

Step-by-step explanation:

${x}^{2} + 7x + 10$

${x}^{2} + 5x + 2x + 10$

$x \times (x + 5) + 2(x + 5)$

$(x + 5) \times (x + 2)$
