Answer:

<u>Options 3, 4 and 5</u>

Step-by-step explanation:

Given:

F(x) = x³ + 3x² - 25x - 75

Factor the given function:

F(x) = x³ + 3x² - 25x - 75

⇒ take x² a common from (x³ + 3x²) and (-25) a common from (- 25x - 75)

F(x) = x²(x+3) - 25 (x+3)

⇒ take (x+3) as a common

F(x) = (x+3) (x² - 25)

(x² - 25) = (x-5) (x+5)

∴ F(x) = (x+3) (x-5) (x+5)

<u>The answer are options 3, 4 and 5</u>

During a sale $.20 candy bars were sold at three for $.50 how much is saved on nine bars

laila [671]

Answer:

30 cents

Step-by-step explanation:

Before the sale 9 candy bars would be .2 x 9 = $1.80. 9 candy bars on the sale would be 9 divided by 3 times .5 which is $1.50. So the savings is 1.80 - 1.50 = .30 or 30 cents.

What is the solution set of negative X equals -8

inessss [21]

Answer:

Step-by-step explanation:

the unknown can NEVER be negative

so you wont see an answer like

-b= 7, -a=98; -k= -9

so,

-x= -8 (change their positions so that the unknown, x, is positive)

x=8

PROBLEM SOLVING You are participating in an orienteering competition. The diagram shows the position of a river that cuts throug

Wewaii [24]

Answer:

The shortest distance is 2.2 miles

Step-by-step explanation:

we know that

The shortest distance you must travel to reach the river is the perpendicular distance to the river

step 1

Find the slope of the line perpendicular to the river

we have

$y=3x+2$

The slope of the river is m=3

Remember that if two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

therefore

The slope of the line perpendicular to the river is

$m=-1/3$

step 2

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

we have

$m=-1/3$

$point(2,1)$

substitute

$y-1=-(1/3)(x-2)$

step 3

Find the intersection point of the river and the line perpendicular to the river

we have

$y=3x+2$ ------> equation A

$y-1=-(1/3)(x-2)$ -----> equation B

Solve the system by graphing

The intersection point is (-0.1,1,7)

see the attached figure

step 3

Find the distance between the points (2,1) and (-0,1,1.7)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute

$d=\sqrt{(1.7-1)^{2}+(-0.1-2)^{2}}$

$d=\sqrt{(0.7)^{2}+(-2.1)^{2}}$

$d=2.2\ miles$

Answer:

Jada should have multiplied both sides of the equation by 108.

Step-by-step explanation:

-4/9=x/108

you must multiply both sides

108*-4/9 = x*108

=-9/4
