The ordered pair(2,-3) is a solution to which of the following inequalities?
a. y-2x>-5
b. y ≥-2x+2
c. 4y+2x≤-1
d. y<3x-9

Answer:

x = {-5, 4}.

Step-by-step explanation:

2x^2 + 2x - 4 = 36

2(x^2 + x - 2 = 18)

x^2 + x - 2 - 18 = 0

x^2 + x - 20 = 0

(x + 5)(x - 4) = 0

x = -5, 4.

The line cannot be formed by the intersection with plane and a cylinder.

What is intersection of cylinder and a plane?

A cylindric section is the intersection of a plane with a right circular cylinder.

Why line cannot be formed by the intersection with plane and a cylinder?

The intersection will be parallel lines if the plane is parallel to the cylinder's axis, it is impossible.

Because there are no intersecting lines on a cylinder, the intersection of a plane and a cylinder cannot create intersecting lines.

Hence, the option [tex]G[/tex] is correct answer.

Step-by-step explanation:

use a calculator and check it

Answer:

 50 %

Step-by-step explanation:

From the diagram attached,

Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1

The number of students that like watching television and reading (WnR) = 70

The total number of students (μ) = 40+20+70+10

The total number of students (μ) = 140

Substitute these values into equation 1

Percentage of total students that like watching television = (70/140)×100

Percentage of total students that like watching television = 1/2(100)

Percentage of total students that like watching television = 50 %

Answer:

$0.25x + $0.05y = $5.45

Step-by-step explanation:

Recall that 1 nickel = $0.05

and 1 quarter = $0.25

Given that the jar contains x quarters and y nickels

The total amount of nickel in the jar

= $0.05y

The total amount of quarter in the jar

= $0.25x

Hence the total amount in the jar considering both nickels and quarters

= $0.25x + $0.05y

Since the jar contains $5.45

then

$0.25x + $0.05y = $5.45

This is the linear equation that represents the relationship between the number of quarters, the number of nickels, and the value of the coins in the jar

Answer:

x(x-2)

Step-by-step explanation:

the common multiple here is the x, notice how it appears in both both terms. thus, we can factor it out of the equation going from x²-2x to x(x-2)

x(x-2)

Im assuming you meant x² - 2x but correct me if i'm wrong!

so x is common in both terms so you can take it out and factorise it.

4)for question 1 there is only a constant terms 2

hence, our answer choice is

5)Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)

hence our answer choices are

6) degree of a expression means the exponent of the expression

since there's no number 3 as exponent

our answer choice is

7) The Standard Form for writing down a polynomial is to put the terms with the highest degree first 

hence our answer choice is

Answer:

1st girl- 2000

2nd girl- 3000

3rd girl- 7000

Step-by-step explanation:

1) add the ratio given: 2+3+7=12

2) the answer that you get is the whole and it is equal to the total: 12/12=12000

3) so now you'll simplify to get the share of each girl: 12/12=12000, what about 2/12(for the first girl)

12/12=12000, what about 3/12(for the 2nd girl)

12/12=12000, what about 7/12(for the 3rd girl)

4) after getting the answer for each, you can add their shares to see if they are equivalent to the total share

Step-by-step explanation:

The question would not give a valid answer, the question should be in the form:

A Florida citrus grower estimates that if 30 orange trees are planted, each tree will produce 500 oranges. For each additional tree planted on the same acreage, the number of oranges each tree produces will decrease by 10 oranges. Find the maximum number of oranges the citrus grower can produce. How many trees will the citrus grower need to plant?

Solution:

Let x represent the number of orange trees above 30 to be planted on the acreage and let y be the number of oranges. Since for every additional tree there is a decrease of 10 oranges, hence:

y = (30 + x)(500 - 10x)

y = 15000 - 300x + 500x - 10x²

y = 15000 + 200x - 10x²

The number of oranges is maximum at y' = 0. Hence:

y' = 200 - 20x

200 - 20x = 0

20x = 200

x = 10

Second derivative test = y" = -20 (so this is maximal)

Therefore the number of trees needed = 30 + 10 = 40 trees

Maximum number of oranges = (30 + 10)(500 - 10(10)) = 40(400) = 16000 oranges

Answer:

Step-by-step explanation:

Given function is,

f(x) = [tex]\sqrt{x}[/tex]

If the given function is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] Or 1.5,

Transformed function will be,

h(x) = [tex]\frac{3}{2}[f(x)][/tex]

h(x) = [tex]\frac{3}{2}(\sqrt{x})[/tex]

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = [tex]\frac{3}{2}(\sqrt{x} )+1[/tex]

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] then shifted 1 unit upward.
