Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=-\sqrt{x+1}$

Find the intercepts

The y-intercept is the value of y when the value of x is equal to zero

For x=0 -----> $y=-\sqrt{0+1}=-1$

The y-intercept is the point (0,-1)

The x-intercept is the value of x when the value of y is equal to zero

For y=0 -----> $0=-\sqrt{x+1}$ -----> $x=-1$

The x-intercept is the point (-1,0)

Find the domain

we know that

The radicand must be positive

$x+1\geq0$

$x\geq-1$

All real numbers greater than or equal to -1

The range is all real numbers less than or equal to -1

using a graphing tool

see the attached figure

What is the answer for this 8k−5(−5k+3)

Helen [10]

Answer:

33k-15

Step-by-step explanation:

8k−5(−5k+3)

8k+25k-15 because -5(-5) equals=25. Two negatives equal a positive.

-5(3)= -15

So the equation changes to 8k+25k-15.

Combine like terms, and you get:

33k-15

Which points lie on the line that passes through point P and is parallel to the given line? Select three options.

gulaghasi [49]

Answer:

So we have (-1,3), (-2,2) and (-5,-1).

Step-by-step explanation:

So we need to find the equation of the line that is parallel to the blue line going through point P.

The slope of the blue line (count the rise/run) is 1/1=1.

Parallel lines have the same slope.

So y=mx+b is the slope-intercept form where m is the slope and b is the y-intercept.

So since the blue line has slope 1 and parallel lines have the same slope then the line going through point P will have slope 1 too.

Point P is actually the y-intercept of the line going through P.

So the equation that is parallel to the blue line going through point P is y=1x+4. b was 4 because it was the y-intercept.

You can also just write y=1x+4 as y=x+4.

Testing the points:

(-4,2)?

Does y=x+4 for this point? 2=-4+4 which gives us 2=0 so no for this point.

(-1,3)?

Does y=x+4 for this point? 3=-1+4 which gives us 3=3 so yes for this point.

(-2,2)?

Does y=x+4 for this point? 2=-2+4 which gives us 2=2 so yes for this point.

(4,2)?

Does y=x+4 for this point? 2=4+4 which gives us 2=8 so no for this point.

(-5,-1)?

Does y=x+4 for this point? -1=-5+4 which gives -1=-1 so yes for this point.

So we have (-1,3), (-2,2) and (-5,-1).

Algebra 2, I need help!!! Solve x^2 + 6x + 7 = 0. If you are going to comment in here please know the answer, this is so serious

docker41 [41]

Answer:

Third option

Step-by-step explanation:

We can't factor this so we need to use the quadratic formula which states that when ax² + bx + c = 0, x = (-b ± √(b² - 4ac)) / 2a. However, we notice that b (which is 6) is even, so we can use the special quadratic formula which states that when ax² + bx + c = 0 and b is even, x = (-b' ± √(b'² - ac)) / a where b' = b / 2. In this case, a = 1, b' = 3 and c = 7 so:

x = (-3 ± √(3² - 1 * 7)) / 1 = -3 ± √2
