Answer:

solution,

given,

x=9 and y=-2

now,

2xy

= 2*9 * -2

= 18 * -2

= -36#

The value 2xy is -36.

Evaluation is the structured interpretation and giving of meaning to predicted or actual impacts of proposals or results.

Given that, x = 9 and y = -2

2xy = 2*2*-9 = -36

Hence, The value 2xy is -36.

Answer:

B.  f(x) = -x^3 - x^2 + 7x - 4

Step-by-step explanation:

For this problem, we want to find the fastest-growing term in our given expressions and equate them when x is - infinite and when x is infinite to see the given trends.

For each of these equations, we will simply take the terms with the highest power and consider those.  The two cases we need to consider is + infinite for x and - infinite for x.  Let's check each of these equations.

Note, any value raised to an even power will be positive.  Any negative value raised to an odd power will be negative.

[A] - x^4

When x is +∞ --> - (∞)^4 -->  f(x) is -∞

When x is -∞ --> - (-∞)^4 --> f(x) is -∞

[B] - x^3

When x is +∞ --> - (∞)^3 --> f(x) is -∞

When x is -∞ --> - (-∞)^3 --> f(x) is ∞

[C] 2x^5

When x is +∞ --> 2(∞)^5 --> f(x) is ∞

When x is -∞ --> 2(-∞)^5 --> f(x) is -∞

[D] x^4

When x is +∞ --> (∞)^4 --> f(x) is ∞

When x is -∞ --> (-∞)^4 --> f(x) is ∞

Notice how only option B, when looking at asymptotic (fastest-growing) values, satisfies the originally given conditions for the relation of x to f(x).

Cheers.

Answer:

Inequaliy: 2x-3(12)>60

X>48

Step-by-step explanation:

Since area of a rectangle is W(L)=A

The inequality given right here including length And width and area Plugged in would be

2x-3(12)>60.  (It’s >60 because the area stated in the problem said to be greater then 60 so we put a Greater then sign)

Combine like terms and solve

2x-36>60

Add 36 on both sides

2x>96

Divide 2 on both sides to isolate variable

x>48

Check:

2(50)-36>60 ( I used 50 because it’s greater then 48 and it’s a easy number to work with for just a check)

solve:

100-36>60

64>60✔️

Answer:

3 ; $11.97

Step-by-step explanation:

Given that:

Balloon options : 15 and 12

Every bouquet has same number of each color :

Greatest possible number of bouquet possible using all the balloons :

Greatest common factor of both 15 and 12:

15 : 1, 3, 5, 15

12 : 1, 2, 3, 4, 6, 12

Hence the greatest common factor of both 15 and 12 is 3

Hence,

Greatest possible number of bouquet possible using all the balloons = 3

If each bouquet is sold for $3.99 :

Earning will be :

Number of bouquet * price per bouquet

3 × $3.99

= $11.97

Answer:

[tex]\huge\boxed{500}[/tex]

Step-by-step explanation:

In order to solve this, we have to note that consecutive numbers are numbers that are one more than the last.

If our first number is represented as [tex]n[/tex], then we know that the next number will be [tex]n+1[/tex], the next will be [tex]n+2[/tex], and so on.

Since we want 4 numbers, we can create the equation:[tex]n + (n+1) + (n+2) + (n+3) = 1998[/tex]

Now we want to solve for [tex]n[/tex]. It's important to note that [tex]n[/tex] is our first number.

Combine like terms:

[tex]4n+6=1998[/tex]

Subtract 6 from both sides:

[tex]4n=1992[/tex]

Divide both sides by 4:

[tex]n = 498[/tex]

We want the third number in the set of these four numbers. Looking back to our equation ([tex]n + (n+1) + (n+2) + (n+3) = 1998[/tex]) we can see that the third term here is [tex]n+2[/tex]

[tex]498+2=500[/tex]

Answer: 13 weeks

Step-by-step explanation:

152.75÷11.75=13

13×11.75= 152.75

Answer: False.

Step-by-step explanation:

Initially, the ratio is 2:7

This means that if we have 2 red marbles, we must have 7 yellow ones.

The quotient here is 7/2 = 3.5

Now, if you add 3 marbles of each colour, then we have:

2 + 3 = 5 red marbles

7 + 3 = 10 yellow marbles.

Now the ratio is 5:10

This means that for every 5 red marbles, we have 10 yellow ones.

But now we can divide both numbers by the same positive integer, because they have a common factor equal to 5.

5/5 = 1

10/5 = 2

Then we have:

5:10 = 1:2

So the new ratio is 1:2

Then the ratio changed when we added the new marbles, which means that Maria was wrong.

Answer:

Step-by-step explanation:

Let x represent the fuel efficiency of one of the cars. Then 45-x is the fuel efficiency of the other. The total miles driven is then ...

  miles = (gallons)×(miles/gallon)

  20x +30(45-x) = 1050

  -10x +1350 = 1050 . . . simplify

  300 = 10x . . . . . . . . . . add 10x-1050

  x = 30 . . . . . . . . . . . . . divide by 10

  45-x = 45-30 = 15

The car using 20 gallons got 30 miles per gallon; the car using 30 gallons got 15 miles per gallon.

Answer:

AB is parallel to AC

Step-by-step explanation:

the product of the gradients of perpendicular line should be -1

AB=2/3

AC=-3/2

2/3*-3/2=-1

=-1

The correct statement is,

⇒ AB is perpendicular to AC.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

We have to given that;

Points are,

A(0, 0), B(3, 2), and C(−2, 3),

Now, We can find slopes as;

AB = (2 - 0) / (3 - 0)

AB = 2/3

AC = (3 - 0)) / (- 2 - 0)

AC = - 3/2

Hence, AB is perpendicular to AC.

Thus, The correct statement is,

⇒ AB is perpendicular to AC.
