Answer:

Monday

Tuesday

Step-by-step explanation:

Given the temperature data:

Mon _____ Tue _____ Wed _____ Thur ___ Fri

-2.5°F ___ - 1.9°F _____ 0°F _____ - 1.5°F _0.5°F

Days colder than - 1.75°F

Days colder than - 1.75°F are days whereby the temperature value is less than - 1.75

Hence,

-2.5°F < - 1.75°F = (Monday)

-1.9°F < - 1.75°F = (Tuesday)

Hence, temperature on Monday and Tuesday is colder than - 1.75°F

Answer:

Monday

Tuesday

Step-by-step explanation:

The volume of box at x = 4 is, 100 cubic units

A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.

We have to given that;

The volume of the box is modeled by the function,

⇒ V (x) = 5x² + 5x

Now, At x = 4;

The volume of the box is,

⇒ V (x) = 5x² + 5x

⇒ V (4) = 5 × 4² + 5 × 4

⇒ V (4) = 5 × 16 + 20

⇒ V (4) = 80 + 20

⇒ V (4) = 100 cubic units

Answer:

Option (D) is correct

Step-by-step explanation:

If y is a multiple of x and versa, it will have a constant of proportionality.

Option (A)

y = (81/3)xy

y will cancel out

1=27x

It is not correct

Option (B)

y=9xy

y will cancel out

1=9x

Option (C)

y=3xy

y will cancel out

1=3x

Option (D)

y = (1/9) x

y will cancel out

x=9y

In option (D), we see that x is 9 times of x. It means it has constant of proportionality equal to 9.

The equation y = 9x represents the constant of proportionality which is equal to 9.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation can also be used to represent direct proportionality as -

y = mx

m = y/x

[m] is called constant of proportionality

We have the constant of proportionality equal to 9

The equation y = 9x represents the constant of proportionality which is equal to 9 as when compared with y = mx, we get m = 9.

Therefore, the equation y = 9x represents the constant of proportionality which is equal to 9.

Answer:

Step-by-step explanation:

Given parameters:

    Number that rode in columns = [tex]3\frac{2}{3}[/tex] times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = [tex]\frac{11}{3}[/tex]R

Number of people that rode in rows  = 2200;

            2200 =  [tex]\frac{11}{3}[/tex]R

             11R  = 2200 x 3

                R  = [tex]\frac{2200 x 3}{11}[/tex]

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

Answer:

pretty sure the answer is "add to eliminate y"

Step-by-step explanation:

since each side is a -2y you do the opposite which is adding :)

hope this helped! Good luck!

The value of x after eliminating the variable y is -9.

The elimination method involves taking one variable out of the system of linear equations by using addition or subtraction along with multiplication or division of the variable coefficients.

Given that the two equations are 9x – 2y = – 75  and 2x – 2y = -12. The equations will be solved as,

9x – 2y = – 75  

2x – 2y = -12

The value of x will be calculated by elimination of the variable y,

9x – 2y = – 75  

-2x + 2y =+12

_____________

7x + 0 = -63

x = -9

Therefore, the value of x after eliminating the variable y is -9.

Answer:

27/3=9 the answer is nine

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The question states that the sum of two numbers is x, and they give us one number which is 12. We know that 12 + 12x cannot equal x. We also know that 12 + 12 + x = x will cancel out the variable. Then, we can eliminate B, as the questions stated that the sum of two numbers is x, and they gave us one number of x. We know that the other number will be the unknown value minus 12, because 12 + x - 12 = x will simplify into x = x, which is true.

An odd number is (2x) + 1

An even number is (2x)

These are the definitions.

Using the binomial (2x + 1)(2x + 1), we can see the properties of all products made from odd numbers.

Foiling will give 4x^2 + 4x + 1.

4x^2 is even because 4x^2 can be expressed as 2(2x) x 2(2x).

4x is even because 4x can be expressed as 2(2x)

This means that 4x^2 + 4x is even so the expression 4x^2 + 4x + 1 is odd because an even number + 1 is odd as shown by (2x) + 1.

This shows that every outcome of the product of 2 odd numbers will result being odd.

This means there is no answer to this problem, because any number that is a multiple of 2 is even. (Basically the definition of even)

Using even and odd numbers concepts, it is found that the product is an even number.

Answer:

Divide both sides by V

Step-by-step explanation:

The equation is not well written.

Mariko needs to solve the equation below for D. Here is the equation:

M = DV

For Mariko to get D, he needs to make D the subject of the formula by dividing both sides of the equation by the coefficient of D i.e V as shown;

Divide both sides by V

M/V = DV/V

V at the denominator will cancel out the V at the numerator to have:

M/V = D

Rearrange

D = M/V

Therefore, the statement which correctly describes the step he should take is:

Divide both sides by V. Option B is correct.
