Answer:

The simplified product has 2 terms.

The simplified product, in standard form, has exactly 2 negative terms.

Step-by-step explanation:

(b-2c)(-3b+c)

distribute and you will get

-3b^2+bc+6bc-2c^2

combine like terms

-3b^2+7bc-2c^2

Who runs the fastest ? (ONLY ANSWER IF YOU KNOW IT BECAUSE CORRECT ONE GETS BRAINLIEST)
Genrish500 [490]

Answer:

<u><em>Stephanie runs the fastest per second: 14 feet per second</em></u>

Step-by-step explanation:

To find the fastest speed, you need to see which person runs the most per second:

Stephanie runs <em>14 feet per second</em>

<em />

Brooke runs 589 feet in 44 seconds.

Find the amount of feet per second by dividing:

\frac{589}{44} =13.4

Brooke runs about <em>13.4 feet per second</em>

<em />

Will runs 1 mile in 454 seconds.

Convert the miles to feet:

There are 5,280 feet in a mile. If Will runs 5,280 feet in 454 seconds, divide to find how much he runs per second:

\frac{5280}{454}= 11.6

Will runs about <em>11.6 feet per second.</em>

<em />

Rob runs 548 feet in a minute.

Convert the minute into seconds. There are 60 seconds in a minute. Divide the feet by the seconds to find how fast he runs per second:

\frac{548}{60}= 9.1

Rob runs about <em>9.1 feet per second.</em>

Stephanie runs 14 feet per second, the fastest time:

| 14 |, 13.4, 11.6, 9.1

<em>Finito.</em>

Which graph shows the line joining the complex numbers -i and 2+!?
Artist 52 [7]

Answer:

D

Step-by-step explanation:

You are given two complex numbers -i and 2+i.

For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.

So, the numbers:

  • -i=0-1\cdot i is represented by the ordered pair (0,-1)
  • 2+i=2+1\cdot i is represented by the ordered pair (2,1).

Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.

The Prize Pretzel Company most popular pretzel sells for $4.80 per bag. The table below shows the cost of these pretzels in vari
Over [174]

Answer:

The price of pretzels in 1975 = $1.80

Step-by-step explanation:

To answer this question we are assuming the steady rate means linear.Let x be the year and y be the price.

We need to find the slope

m = (y2-y1)/(x2-x1)

  = (4.80-4.05)/(2015-2005)

  =.75/10

 = .075

The slope is .075

We can use the point slope form of the equation  

y-y1 = m(x-x1)

y-4.80 = .075(x-2015)

Distribute

y - 4.80 = .075x -151.125

Add 4.80 to each side

y - 4.80+4.80 = .075x -151.125+4.80

y =  .075 x - 146.325

We want to find out how much pretzels were in 1975.  Put in x=1975

y = .075(1975) -146.325

y = 148.125-146.325

y=1.80
