please help me with this i don’t understand at all!

Answer:

Step-by-step explanation:

6x + 19 + x = 180

7x + 19 = 180

7x = 161

x = 23°

6(23) + 19= 138 + 19 = 157°

Answer:

[tex](-\infty,-4.6)[/tex]

Step-by-step explanation:

So we have the inequality:

[tex]-4(x+4)>x+7[/tex]

First, let's distribute the left:

[tex]-4x-16>x+7[/tex]

Now, let's add 16 to both sides:

[tex]-4x>x+23[/tex]

Subtract x from both sides:

[tex]-5x>23[/tex]

Divide both sides by -5. Since we're dividing by a negative, flip the sign:

[tex]x<-4.6[/tex]

This is saying all values less than -4.6.

In other words, in an interval, this would be from negative infinity all the way up to -4.6. Thus:

[tex](-\infty,-4.6)[/tex]

We do not use brackets because we do not include -4.6 into our set.

And we're done!

Answer:

x = 34

Step-by-step explanation:

(x - 9(16/8)) = 16

(x - 9(2)) = 16                        Divide 16 and 8

x - 18 = 16                             Multiply 9 and 2

x = 34                                   Add 18 to both sides

Answer: You switch the point in the x-axis to the negative/positive of the number.

Step-by-step explanation:

So for example if you have the point (3,7), you would switch the 3 to -3 and you would keep the y the same.

Hope this helps!

Hello! I can help you! I did not know what numbers you needed so I worked on problems 43- 46. For problems 43 and 44 you are going to be doing the same thing, but I can show you have to do both. So for number 43, y=-4x-2; (0,-1), you want to keep it parallel, so you are going to keep the slope ( -4) the same. You use point slope form which is y-y1=m(x-x1) and you plug it in. So I used the points that they gave at the top (0,-1) which means 0 is x and -1 is y so my new equation in point slope is y+1=-4(x-0). I did y+1 instead of y-1 because two negatives make a positive so the negative 1 makes the equation positive. After I wrote the equation, I solved it by distributing the -4 to the numbers in the parentheses (x-0). I got y+1=-4x and from there I just subtracted 1 on both sides so all that’s left is y=-4x-1 and that’s the answer for 43. You would do the same thing for number 44 but instead of getting the question in slope form you need to get there. You would just subtract 2x on both sides and get -y=-2x-4 and from there you divide a negative 1 on both sides so that y is positive ( y is always positive) and your equation will be y=2x+4 and then you do the same thing you did for question 43 with the point slope information. For the next to problems, 45 and 46, it going to be a little different but it’s not too difficult. Instead of just taking the slope and plugging it into the point slope equation you need to flip the reciprocal and make it negative. So for 45, 2/3 would turn into -3/2 and that is what you would plug into the equation. It would be y+2=-3/2(x+6) and you would solve and get y+2=-3/2x-9 from there you would subtract 2 on both sides and you would get y=-3/2-11. You would do the same for number 46, except in the beginning you need to subtract 4x from both sides to get y=4x-6 and the just flip the reciprocal and make it negative ( -1/4x). I hope that helped you understand! Good luck! :)

Answer:

x = 7

y = -7/2

Step-by-step explanation:

(x+6i)=(3-i)+(4-2yi)​

First look at the real parts

x = 3 +4

x = 7

Then look at the imaginary part

6i= -i -2yi

6 = -1-2y

Add 1 to each side

6+1 = -2y

7 = -2y

Divide by -2

7/-2 = y

Answer:

Infinite Solutions.

Step-by-step explanation:

3x+2y=8 for x:

3x+2y=8

3x+2y+−2y=8+−2y(Add -2y to both sides)

3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)

x= −2 3 y+ 8 3

Substitute −2/3y + 8/3 for x in 4.5x+3y=12:

4.5x+3y=12

4.5( −2/3y+ 8/3 )+3y=12

12=12(Simplify both sides of the equation)

12+−12=12+−12(Add -12 to both sides)

0=0

Infinitely many solutions.

Answer:

Infinite Solutions.

Step-by-step explanation:

3x+2y=8 for x:

3x+2y=8

3x+2y+−2y=8+−2y(Add -2y to both sides)

3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)

x= −2 3 y+ 8 3

Substitute −2/3y + 8/3 for x in 4.5x+3y=12:

4.5x+3y=12

4.5( −2/3y+ 8/3 )+3y=12

12=12(Simplify both sides of the equation)

12+−12=12+−12(Add -12 to both sides)

0=0

Infinitely many solutions.

We have given that,

Gemma, a scuba diver, begins a dive on the side of a boat 4 feet above sea level. She descends 28 feet.

An integer is colloquially defined as a number that can be written without a fractional component.

We have to determine which integer represents Gemma’s position with respect to sea level

Because if she rises up 4, it is +4.

Then subtract 28 from 4. That makes it -24.
