Answer:

C ( x = 2 (multiplicity of 2), x = -2, x = -4)

A ( x = 5 (crosses), x = -3 (touches))

Step-by-step explanation:

Here are a couple of rules that helped me come to these answers.

1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.

2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.

3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.

Answer:

Not positive but im pretty sure it is the first one.

Step-by-step explanation:

Answer:  Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Step-by-step explanation: y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x-3y+15  = 0 and calculate its properties

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

 y-intercept = 15/3  =  5

When y = 0 the value of x is -15/1 Our line therefore "cuts" the x axis at x=-15.00000

 x-intercept = -15/1  = -15.00000

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 5.000 = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.667/2.000 =  0.333

 Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Answer:

  21 cm

Step-by-step explanation:

The two pieces have a length ratio of 1 : 4, so the shorter piece is 1/(1+4) = 1/5 of the total length.

 105 cm/5 = 21 cm

The shorter piece is 21 cm.

Triangles

An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.

The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:

8x+3=67

Reducing:

8x=67-3=64

Solving:

x=64/8

x=8

Answer:

The correct option is;

[tex]\dfrac{x + 40}{x + 160} = 0.333[/tex]

Which is of the form of option C with 2 replaced by x and the characters formatted

Step-by-step explanation:

The given parameters are;

Jose's present batting average = 0.250

The number of times he was at bat = 160

The number of times he made a hit = 40

The batting average he wants to improve to = 0.333

If he makes a hit the next x times he was at bat is represented as if he makes a hit each time, for the next x time he was at bat. We have;

The number in times he makes a hit the next x times he was at bat = x

Therefore, we get;

New total number of hits Jose makes = 40 + x = x + 40

New total number of time Jose was at bat = 160 + x = x + 160

Therefore, given that Jose intends to improve his batting average to 0.333, and that the batting average is given by the relation;

[tex]Batting \ average = \dfrac{The \ number \ of\ hits}{The \ number \ of\ at \ bat }[/tex]

To find x, we have;

[tex]0.333 = \dfrac{x + 40}{x + 160}[/tex]

Therefore, the correct option is most likely C. where the 2 is supposed to be x.

B JUST DID THE QUIZ

Step-by-step explanation:

FOR FUTURE PPL ON EDGE 2022!!

The relationship between angles A and B is B. They are complementary.

In a proper triangle, the hypotenuse is the longest aspect, an "opposite" aspect is the only across from a given attitude, and an "adjacent" side is subsequent to a given angle. We use special words to describe the perimeters of proper triangles.

All triangles have three aspects and three corners (angles). The point at which two sides of a triangle meet is known as a vertex. the base of a triangle may be any one of its 3 aspects, but it also includes the lowest one.

Have a nice day sunshine

Given:

The lake started with only  4 square feet infected.

The bacteria are growing by a factor of 3  every hour.

To find:

The domain for this situation.

Solution:

Initial value = 4 square feet

Growth factor = 3

Using exponential growth model, we get

[tex]y=ab^t[/tex]

where, a is initial value and b is growth factor.

So, square feet of bacteria after t hours is

[tex]y=4(3)^t[/tex]

Here, domain is set of values of time and range is square feet of bacteria.

Above equation is defined for all values of t but we know that, time cannot be negative.

As the relationship between hours and square feet of bacteria is  continuous, therefore the value of t can be any real number greater than or equal to 0.

[tex]Domain=\{t|t\in R\text{ and }t\geq 0\}[/tex].

Therefore, the domain is [tex]\{t|t\in R\text{ and }t\geq 0\}[/tex].

Step-by-step explanation:

Step-by-step explanation:

we can proceed to model the cost of Billy's Boat Rental Company

let y be the cost

let x be the number of rentals

y=105+9.5x----1

Also, the cost of Billy's Boat Rental Company

y=14.75------2

the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"

we have to equate the two cost and solve for x

105+9.5x=14.75

105-14.75+9.5x=0

90.25+9.5x=0

9.5x=-90.25

divide both sides by 9.5 we have

x=-90.25/9.5

x=9.5

Answer:

The equation of the line is 6y = 7x + 23

Step-by-step explanation:

We begin by calculating the slope of the line;

mathematically, the slope is given by;

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

That would be;

m= (5-(-2))/(1-(-5))

m = 7/6

So the equation becomes;

y = 7/6x + b

We below need to get the value of the y-intercept b

We get this by making a substitution for any of the two points

Let’s say we make the substitution for (-5,-2) in which case y = -2 and x = -5

Thus, we have

-2 = 7/6(-5) + b

-2 = -35/6 + b

b = -2 + 35/6

b = (-12+ 35)/6 = 23/6

So we have;

y = 7/6x + 23/6

let’s multiply through by 6

6y = 7x + 23

Answer:

0.08

Step-by-step explanation:

1.7 – 2.7 – 1.34 + 4.9 – 1.48

 2.7

- 1.7       (subtract 1.7 from 2.7)

--------

-1.0      [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore  1.0 is negative]

-1.0-1.34

we know that  (-) (-) is (+)

therefore add -1.34 with -1.0

   1.34

+  1.0

-----------

  -2.34 [since 1.34 is greater and it is negative]

-2.34+4.9

we know that (-)(+) is (-)

therefore subtract -2.34 from 4.9

  4.90  ← (we put zero so that we can subtract without getting confused)

-  2.34

------------

  1.56 [1.56 is positive because 4.9 is greater and it is positive]

1.56-1.48

here, digit before the decimal point is same but  after decimal point .56 is greater than .48  therefore subtract 1.48 from 1.56

  1.56

-  1.48

-----------

  0.08

therefore,  1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

hope it helps you!
