Answer:

x≤-3      2 ≤x<7  

Step-by-step explanation:

(x^2+x-6) /(x-7) ≤0

Factor the numerator

(x+3)(x-2) / (x-7)≤0

Critical points are

X =-3  X =2  X=7

We need to check the values when

x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

x≤-3

(negative)(negative) / (negative) =   negative

-3 ≤x≤2    

(positive)(negative) / (negative) = positive  this range does not work

      2 ≤x<7  

(positive)(positive) / (negative) = negative

x>7

(positive)(positive) / (positive)

Answer: Roses= 75, Sunflowers= 45

Step-by-step explanation:

Add the ratios- 5 + 3 = 8

Divide the total by the sum = 120 ÷ 8 = 15

Multiply the ratios- 5 x 15 = 75 and 5 x 3 = 45

∴ 5:3 = 75 , 45

The statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.

A parallelogram is a polygon with four sides, opposite sides of the parallelogram are parallel.

The parallelogram ABCD is shown in the figure.

A parallelogram is a type of quadrilateral,

The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.

The parallelogram has two diagonals, AC and BD.

From the property of Parallelogram,

The diagonals of a parallelogram bisect each other.

So, AC and BD bisect each other.

AE = ECBE = CE

The correct answer is BE ≅ DE.

Thus, the statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.

Answer:

A.400

Step-by-step explanation:

Well perimeter for a rectangle is l+l+w+w

100+100+l+l=600

200+2l=600

Subtract 200 from both sides

2l=400

Divide both sides by 2

l = 400 feet

The length of the rectangle is 400 feet long.

Answer:

The distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].

Step-by-step explanation:

Given that: AB = a

                  AP = 2PQ = 2QB

Thus,

PQ = QB = [tex]\frac{a}{4}[/tex]

PQ + QB = [tex]\frac{a}{4}[/tex]+ [tex]\frac{a}{4}[/tex]

              = [tex]\frac{a}{2}[/tex]

AP = [tex]\frac{1}{2}[/tex] a = [tex]\frac{a}{2}[/tex]

The distance between midpoint of AP and QB can be determined as;

[tex]\frac{AP}{2}[/tex] + PQ + [tex]\frac{QB}{2}[/tex]

= [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{8}[/tex]

= [tex]\frac{2a+2a+a}{8}[/tex]

 = [tex]\frac{5a}{8}[/tex]

Therefore, the distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].

Answer:

0.67 gallon of water

Answer:

1.548 gallons

Step-by-step explanation:

Length of the rectangular wall = 25.1 ft.

Width of the rectangular wall = 18.5 ft.

Area of the rectangular wall = length * width = 25.1 * 18.5

= 464.35 square feet

300 square feet wall can be painted using 1 gallon of paint.

=> 1 square feet wall can be painted using  gallon of paint.

=> 464.35 square feet wall can be painted using  gallon of paint.

= 1.548 gallons of paint

Answer:

4 gallons

Step-by-step explanation:

The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

The unit rate of change between variables is the quotient between the difference between y-values and the difference between x-values

The unit rate of change is y = 2.25x

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the values of x be set A = { 2 , 3 , 4 }

Let the values of y be set B = { 4 1/2 , 6 3/4 , 9 }

So , the unit rate of change can be calculated by slope and linear equation of line

So , Slope m is

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( 6 3/4 - 4 1/2 ) / ( 3 - 2 )

m =  2.25

So , the equation will be y = mx

y = 2.25x

Therefore , the unit rate of change is y = 2.25x

Hence ,

The unit rate of change is y = 2.25x and the graph is shown below

Answer:

A. True

Step-by-step explanation:

The Triangle Inequality Theorem says that the sum of any two sides must be greater than the third side. Let's see if this is true.

a + b

9 + 1 = 10>9

a + c

9 + 9 = 18>1

c + b

9 + 1 = 10>9

True, the segments shown below could form a triangle. Option A is correct.

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

According to the Triangle Inequality theorem, any two sides' total must be bigger than the third side. Verify one by one;

⇒a + b>c

⇒9 + 1 >9

⇒10>9

a + c>b

9 + 9 >1

18>1

c + b>a

9 + 1 >9

10>9

True, the segments shown below could form a triangle.

2 numbers  : 10 and -10

Answer:

(g + f)(x)

Step-by-step explanation:

the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).

The expression of function H (x) is (g + f) (x).

Option 2 is true.

Here,

The function f (x) = -x - 4 and g(x) = x + 3

The value of H (x) is in the table is -1.

We have to find the expression to represents H(x).

What is Linear function?

A linear function is a simple function usually composed of constants and simple variables without exponents.

Now,

The function f (x) = -x - 4 and g(x) = x + 3

⇒( f + g ) (x) = f (x) + g(x)

                  = -x - 4 + x + 3

                  = -1

Which is same as the value of H (x) is in the table.

Hence, The expression of function H (x) is (g + f) (x).

Option 2 is true.
