A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [

Answers

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3

Answers

Answer:

∠p= 15° , ∠q = 108° , ∠r = 57° Is the Answer

Step-by-step explanation:

, (x -12)° + (5x-27)° + (2x + 3)° = 180°

or, 8x° -36° = 180°

Or x =

So, x = 27°

∴ ∠P = 27° -12° = 15°

∠q = (5 × 27)° -27° = 108°

∠r = (2 × 27)° + 3° = 57°

please help me (see picture)

Answers

Answer:

107 degrees

Step-by-step explanation:

to find x = 180 - (180-73-34)

Simplify
(8x + 3)(2^2+ 8x +9)

Answers

Answer:

64x²+128x+39

Step-by-step explanation:

Answer:

First distribute (8x + 3) into (2^2+ 8x +9)

16x^3 + 64x^2 + 72x + 6x^2 + 24x +27

Then we'll order the pairs from highest to lowest degree

16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27

Then we'll add up the like terms

16x^3 + 70x^2 + 96x + 27

That should be your final answer simplified.

y = 2x – 1
x + y = 2

Answers

Answer:

x = 1, y = 1

Step-by-step explanation:

plug y = 2x - 1 into the equation x + y = 2:

[tex]x + (2x - 1) = 2\\3x - 1 = 2\\3x = 3\\x = 1[/tex]

plug that into the equation y = 2x - 1

[tex]y = 2*1-1\\y=2-1\\y=1[/tex]

The sum of 6.7 and a number is negative. What is a possible value for that number? Explain.

Answers

Answer:

The number must be greater than 6.7. Thus, the sum will be negative.

For example, the number could be 7.

6.7 - 7 = -0.3

The number can be in the range - x ∈ (- ∞ , - 6.7)

We have - the sum of 6.7 and a number is negative.

We have to determine the possible value of that number.

For what range of values of x, the given function is equals to a negative value -y = f(x) = 2x + 10

For f(x) to be negative -

f(x) < 0

2x + 10 < 0

2x < - 10

x < - 5

x ∈ (- ∞ , - 5)

According to the question, we have - the sum of 6.7 and a number is negative.

Now -

6.7 + x < 0

x < 6.7

x ∈ (- ∞ , - 6.7)

Hence, the number can be in the range - x ∈ (- ∞ , - 6.7).

solve 2x+6=34 i have no idea pls exsplain and help me :)

Answers

You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28

Then divide both side by 2 so you get x=14 which is your answer :)

ANSWER: x=14

Answer:

Step-by-step explanation:

okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this

so you’re gonna start off by separating the 2x from the 6=34.

now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)

now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.

2 x 14 + 6 = 34?

2 x 14 = 28 + 6 = 34.

34 = 34

so, x is 14. hope this helped!
