(-64=)-8+6=-2+(-16=)-4-3=5
Answer:
50Step-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
2. Sketch the graph: 4y – 3x = 12.
Answers
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.
An object is translated by (x-2, y-6). If one point in the pre-image has the coordinates (-3, 7,) what would be the coordinates of this image
Answers
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 )

Solve: - (g+ 12) = 5(9 - 12)
Answers
Answer:
-27
Step-by-step explanation:
(g+ 12) = 5(9 - 12)
g = 45 - 60 - 12
g = - 27
Answer:
g = 3
Step-by-step explanation:
- (g+ 12) = 5(9 - 12) (remove parentheses by distributive property. See attached for reference)
g(-1) + 12(-1) = 9(5) -12(5)
-g - 12 = 45 - 60
-g - 12 = -15 (add 12 to both sides)
-g = -15 + 12
-g = -3 (multiply both sides by -1)
g = 3

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:

Divide both sides by 4:

Represent this statement as an equation: The difference of twice a number and 3 is 11.
Answers
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.

the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)
Answers
Answer:
HJ = 15Step-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
