Answer 1

Answer:

Hi there! :)

Answer:

Choice D. (y - 4) = 3(x + 2)

Step-by-step explanation:

An equation in point-slope form is:

(y - y1) = m(x - x1)

Where:

y1 = y-coordinate of a point

m = slope

x1 = x-coordinate of a point

In this instance, the point given is (-2, 4) with a slope of 3. Therefore, the equation in point-slope form would be Choice D. (y - 4) = 3(x + 2)

Answer 2

Answer:

Step-by-step explanation:

answer is C

Because formula of equation of slop is

Y-y1=m(x-x1)

Answer: B. -3a^2 + 11a + 5

1.) Remove parentheses.

3a−3a^2 +5+8a

2.) Collect Like Terms.

(3a+8a) - 3a^2+5

3.) Simplify.

11a - 3a^2+5

-3a^2 + 11a + 5

Verify
tanx + cotx = 1/ sinxcosx

What value of x makes the equation true? PLZ HELP RIGHT THANK YOU

–7.12 = –4.8 + x

A.

–11.92

B.

–11.2

C.

–2.32

D.

2.32

Answers

so just remember tha tyou can do anything to an equation as long as you do it to both sides (except divide by 0) so
-7.12=-4.8+x
add 4.8 to both sides since -4.8+4.8=0 so it cancels
4.8-7.12=x
simplify
4.80-7.12=-2.32
-2.32=x
the naswer is C

-7.12 = -4.8 + x

-7.12 = x - 4.8

Add 4.8 on both sides

x = -7.12 + 4.8

x = -2.32

Your final answer is C. -2.32.
