Answer 1

Answer:

Look below

Step-by-step explanation:

To figure whether a line is perpendicular or parallel check the slopes

When a line is parallel the slopes are the same

When a line is perpendicular the slopes are negative reciprocals

40. Neither (They aren't the same nor a negative reciprocal)

41. Neither (When you put y on the left it isn't a reciprocal)

42. Parallel (The slopes are both -3/2)

To do 43-44 make sure that the slopes are the same then plug in the points to to find the y-intercept (make sure you solve for b)

43. y = -4x - 1

44. y = 2x + 1

For 45-46 do the same thing, but make sure you change the slope to a negative reciprocal since its perpendicular

45. y = -3/2x-11

46. y = 1/4x+4

if the fraction 396/x-10 is equivalent to -22, find the value of x.

Answers

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

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

Answer:

50

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

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.
