Step-by-step explanation:

(-64=)-8+6=-2+(-16=)-4-3=5

Answer:

Step-by-step explanation:

(6 + √-64) (3 - √-16)

= (6 + 8i) (3 - √-16)

= (6 + 8i) (3 - 4i)

= (6 * 3 - 8 (-4)) + (6(-4) + 8 * 3)i

= 6 * 3 - 8(-4) = 50

= 6(-4) + 8*3 = 0

= 50 + 0i

= 50

Answer:

2x - 3 = 11

Step-by-step explanation:

"difference" means subtraction, so it is subtraction.

"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.

"Is 11" just means equals 11.

so, 2x - 3 = 11.

hope this helps!

Answer:

(-7,-3)

Step-by-step explanation:

From A to M, the x value went down 2.  If it goes down another 2, it will be at -7.

From A to M, the y value went down 3.  If it goes down another 3, it will be at -3.

(-7,-3)

Answer:

17) 40°

18) 3x+22

19) (1,-4.5)

20) (-1,-2.5)

Step-by-step explanation:

17) 99=59=40°

18) 2x+7+x+15=3x+22

19) 6-(-8)=14

14/2=7

-8+7=1

-2-(-7)=5

5/2=2.5

-2-2.5=-4.5

midpoint = (1,-4.5)

20) 6-(-8)=14

14/2=7

-8+7=-1

5-(-10)=15

15/2=7.5

-10+7.5=-2.5

Midpoint = (-1,-2.5)

Answer:

  see below

Step-by-step explanation:

A graphing calculator is useful for this.

__

To find the x-intercept, set y=0 and solve for x:

  0 -3x = 12

  x = -4 . . . . . . divide by -3

To find the y-intercept, set x=0 and solve for y:

  4y - 0 = 12

  y = 3 . . . . . . divide by 4

Plot the x- and y-intercepts on their respective axes and draw a line through them.

Answer:

Step-by-step explanation:

To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)​, we will use the formula for calculating the distance between two points as shown;

D = √(x₂-x₁)²+(y₂-y₁)²

From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5

HJ = √(8-(-1))²+(-5-7)²

HJ = √(8+1)²+(-12)²

HJ = √81+144

HJ = √225

HJ = 15

Hence the length of segment HJ is 15 units

Answer: x = -8

Step-by-step explanation:

1. Miltiply x-10 on both sides: 396 = -22(x - 10)

2. Distribute -22 to (x - 10): 396 = -22x + 220

3. Subtract 220 from 396: 176 = -22x

4. Divide both sides by -22 to get x by itself: x = -8

I hope this is helpful :)

Answer:

(- 5, 1 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 2, y - 6 )

This means subtract 2 from the original x- coordinate and subtract 6 from the original y- coordinate, that is

(- 3, 7 ) → (- 3 - 2, 7 - 6 ) → (- 5, 1 )

Answer:

Answer:

x-10 = 3(x+6)

Step-by-step explanation:

The difference between x and 10

(x-10)

Is the same thing as 3*(x+6)

=3(x+6)

Answer:

[tex]9.25[/tex]

Step-by-step explanation:

So we have the equation:

[tex]15-2(3-2x)=46[/tex]

First, distribute the -2:

[tex]15-2(3)-2(-2x)=46[/tex]

Multiply:

[tex]15-6+4x=46[/tex]

Subtract:

[tex]9+4x=46[/tex]

Subtract 9 from both sides:

[tex]4x=37[/tex]

Divide both sides by 4:

[tex]x=37/4=9.25[/tex]

And we're done!

Answer:

All of the above

Step-by-step explanation:

A whole number and integers are numbers that don't have decimals.

A rational number is a number that can be written as a fraction

A real number is any number that is not complex, which means that it has an imaginary solution or imaginary number part of it.
