Graph: y +2=

olga_2 [115]

Answer:

see below

Step-by-step explanation:

The point-slope form of the equation of a line is ...

y -h = m(x -k)

for a line with slope m through point (h, k).

Comparing this to the given equation, you see that ...

h = -2, m = 1, k = -4

The line has a slope of 1 and goes through the point (-4, -2). This information is useful for graphing.

You can also rearrange the equation to slope-intercept form by subtracting 2 from both sides.

y = x +2

This has a slope of 1 and crosses the y-axis at y=2. It graphs the same as the above.

What angle has a tangent and sine that are both negative? 300 210 45 150

zimovet [89]

Answer:

$300^{\circ}$

Step-by-step explanation:

$\text{In quadrant IV, both ratios of tangent and sine are negative.}\\ \\300^{\circ}~ \text{lies in the fourth quadrant, so}~ \tan 300^{\circ} ~ \text{and}~ \sin 300^{\circ}~ \text{are negative.}$

Consider the radical equation √c+22 = c + 2.

dimulka [17.4K]

First square both sides to get:

c + 22 = (c + 2)^2

c + 22 = c^2 + 4c + 4

Move the terms on the left side to the right side:

c^2 + 3c - 18 = 0

Factor to get:

(c + 6) * (c - 3) = 0.

The solutions are c = -6 and c = 3.

Check to see if these answers work by plugging them into the original equation:

c = -6:

sqrt (-6 + 22) ?= -6 + 2

But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.

c = 3:

sqrt (3 + 22) ?= 3 + 2

5 = 5. So, 3 works.

The answer is: B
