What does |-100| equal?

2 answers:

7 0

The two straight lines around the number indicate absolute value. Absolute value is the distance from the number to zero (essentially how many marks away on a number line).

$0 - (-100)$
$0 + 100$
$100$

It is equal to 100.

It would equal 100 because you are taking -100 and basically doing the opposite so it would be 100

Complete the equation of the line through (-9 -9) and (-6 0)

Katena32 [7]

Answer:

y = 3x + 18

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, - 9) and (x₂, y₂ ) = (- 6, 0)

m = $\frac{0+9}{-6+9}$ = $\frac{9}{3}$ = 3, thus

y = 3x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (- 6, 0), then

0 = - 18 + c ⇒ c = 0 + 18 = 18

y = 3x + 18 ← equation of line

Can someone explain to me the steps how they got 2 √4^2+2x-3-2 from this question…

Naddik [55]

Step-by-step explanation:

with your square root symbol I never know what is inside the square root and what is possibly outside.

so, I can only guess and see what comes close.

f(x) = 2x² + x - 1

g(x) = sqrt(2x - 1) ??? is that so ?

h(x) = -2

2g(f(x)) + h(x)

g(f(x)) means that the whole f(x) expression is used as x in g(x).

the whole combined function is then

2×sqrt(2(2x² + x - 1) - 1) - 2

2×sqrt(4x² + 2x - 2 - 1) - 2

2×sqrt(4x² + 2x - 3) - 2

and if I am not mistaken, then this is the solution you mentioned at the beginning (if I try to read between the typos and missing info).

this is how people get to this.

do you understand it now ? or is there still something unclear ?

consider this quadratic equation x2+2x+7=21 the nuber of positive solutions to this equation are blank. the approximate value of

S_A_V [24]

Answer:

x²+2x+7-21=0

 x²+2x-14. =0

 x²+2x. =14

 x²+2x+1. =14+1

 (X+1)². =15

 X+1. =+/-√15

 X=-1+/-√15

X=-1+3.872983346207

 =2.872983346207(greatest solution) round it as possible

X=-1-3.872983346207

 =-4.872983346207
