What is the difference?

Len [333]

Answer:

Step-by-step explanation:

x/(x²+3x+2) - 1/[(x+2)(x+1)]

x² + 3x + 2 = x² + 2x + x + 2

= x(x + 2) + (x + 2)

= (x + 2)(x + 1)

= x/[(x+2)(x+1)] - 1/[(x+2)(x+1)]

= (x-1)/[(x+2)(x+1)]

= (x-1)/(x²+3x+2)

Solve for x in the equation x2-8x+41=0

Alinara [238K]

Answer:

d) 4 ± 5i

Step-by-step explanation:

Here we have to use the quadratic formula.

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41

Now plug in the given values in the above formula, we get

x = $\frac{-(-8) +/- \sqrt{(-8)^2 - 4*1*41} }{2*1}$

Simplifying the above, we get

x = $\frac{8 +/- \sqrt{64 - 164} }{2}$

x = $\frac{8 +/- \sqrt{-100} }{2}$

[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]

x = (8 ± 10i )/2

Now dividing by 2, we get

x = 4 ± 5i

The answer is d) 4 ± 5i

Hope you will understand the concept.

Thank you.

A rectangle is transformed according to the rule r0, 90º. the image of the rectangle has vertices located at r'(–4, 4), s'(–4, 1

Korvikt [17]

Answer:

Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

Counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Step-by-step explanation:

Given : rectangle has vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4)

To find : transformed according to the rule 90º , what is the location of q?

Solution : we have given that

vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4).

By the rule of 90º rotation clock wise rule : (x ,y ) →→ ( y , -x )

90º rotation counter clock wise rule : (x ,y ) →→ ( -y , x ).

Then Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Therefore, Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Whats the inequality in the graph?

Kazeer [188]

Answer:

y=2x-5

Step-by-step explanation:

Slope is rise over run, or y/x

The points given were (0,-5) and (-1,-3)

Using y2-y1/x2-x1 we can find the slope.

-3-(-5)/-1-0 = 2/-1 = -2 = slope

Next, we have to find the y-intercept. The y-intercept is where the point on the line meets the y-axis.

This point is shown at -5.

Now, putting our information into y=mx+b (slope-intercept form)

y=2x-5

2 is our slope

-5 is our y intercept
