Answer:

C ) y = -2x

Step-by-step explanation:

(2, -4)

y = -2x

subsitute x for the value of x

y = -2(2)

-2 × 2 = -4

y = -4

so

the equation for the point (2, -4) is

y = -2x

A train is going on a journey. First it travels east for 50 kilometers. Then it turns north and travels for 22 kilometers. Next it goes west for 50 kilometers. Finally, it travels south for a certain number of kilometers. At the end of its journey it is back at its original location. How many kilometers did it travel in the southward direction?

Answer:

This equation is false.

Step-by-step explanation:

27x15=405

You're doing the distributive property here so you're supposed to add but they subtract. Since you're doing 20x15 you have to add because 27-20=7.

The equation 27 × 15 = (20 × 15) – (7 × 15) is false.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The distributive property is the distributed law of multiplication over operations in fundamental algebra, such as adding and subtracting.

The expression is given below.

⇒ 27 × 15

The expression can be written as,

⇒ 27 × 15

⇒ (20 + 7) × 15

⇒ 20 × 15 + 7 × 15

The equation 27 × 15 = (20 × 15) – (7 × 15) is false.

48/4= 12

Hope this helped. ;)

Answer:

12 students are in a group

Step-by-step explanation:

There are 87 first graders, but 39 students are picked up. So, we have to calculate how many students are left.

87 - 39 = 48

There are 48 students left.

The teacher divided these 48 students intro 4 groups.

48 / 4 = 12

So, there are 12 students in a group.

Answer:

Square root 100

Step-by-step explanation:

A rational number is a number that can be completely expressed by a fraction. In this case, 100 is the only square number so only the square root of 100 will result in a rational number (10) or (10/1). The others are not square numbers so square rooting them will result in a long line of decimal points which cannot be expressed by a fraction.

Hope this helped!

Answer:

The square root of 100 is a rational number.

Step-by-step explanation:

The square root of 100 is 10. A rational number is a number that can be made by dividing two integers (whole numbers). 10 ÷ 1 = 10. None of the other options are integers, so they are out.

Step-by-step explanation:

First add the sum of the Javi's total page count from Monday to Friday. You get 125 pages. Next find MeriAnne using the same process. You get 120 pages. Find the difference by subtracting one from the other. 125-120=5 page difference.

Javi wins from MeriAnne by 5 pages

Data is information that has been translated into a form that is efficient for movement or processing. Relative to today's computers and transmission media, data is information converted into binary digital form. It is acceptable for data to be used as a singular subject or a plural subject.

Total number of pages read by Javi

=10+20+60+20+15

=125

Total number of pages read by MeriAnne

=20+30+40+20+10

=120

So, Javi wins from MeriAnne by= 125-120= 5 pages

Answer:

The answer is C

Step-by-step explanation:

Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?

(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.

The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.

Answer:

Step-by-step explanation:

Given the complex notations a = 5i + j, b = i − 2j, we are to evaluate the following:

1) a + b

= 5i+j + (i-2j)

= 5i+j+i-2j

collect like terms

= 5i+i+j-2j

= 6i-j

Hence a+b = 6i-j

2) 2a+3b

= 2(5i+j) + 3(i-2j)

open the parenthesis

= 10i+2j+3i-6j

collect like terms

= 10i+3i+2j-6j

= 13i-4j

Hence 2a+3b = 13i-4j

3) |a| = √x²+y²

Given a = 5i+j; x = 5, y = 1

|a| = √5²+1²

|a| = √25+1

|a| = √26

4) |a-b|

First we need to calculate a-b

=  a - b

= 5i+j - (i-2j)

open the parenthesis

= 5i+j-i+2j

collect like terms

= 5i-i+j+2j

= 4i-3j

|a-b| = √4²+(-3)²

|a-b| = √16+9

|a-b| = √25

|a-b| = 5

Answer:

Step-by-step explanation:

Given the order of operations A set of three scores to consists of the values 6, 3, and 2, we are to evaluate the following

1) Σ2X – 2

= 2(6)+2(3)+2(2) – 2

= 12+6+4–2

= 22–2

= 20

2) Σ(2X)² = (2×6)²+(2×3)²+(2×2)²

Σ(2X)² = 12²+6²+4²

Σ(2X)² = 144+36+16

Σ(2X)² = 144+52

Σ(2X)² = 196

The results of the order of operations are: [tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]

The scores are given as:

x = 6, 3 and 2

This is represented as:

[tex]\sum 2x -2[/tex]

So, we have:

[tex]\sum 2x -2 = 2 \times 6 - 2 + 2 \times 3 - 2 + 2 \times 2 - 2[/tex]

Evaluate the products

[tex]\sum 2x -2 = 12 - 2 + 6 - 2 + 4- 2[/tex]

[tex]\sum 2x -2 = 16[/tex]

This is represented as:

[tex]\sum (2x)^2[/tex]

So, we have:

[tex]\sum (2x)^2 =(2 \times 6)^2 + (2 \times 3)^2 + (2 \times 2)^2[/tex]

Evaluate the products

[tex]\sum (2x)^2 =12^2 + 6^2 + 4^2[/tex]

Evaluate the squares

[tex]\sum (2x)^2 =144 + 36 + 16[/tex]

[tex]\sum (2x)^2 =196[/tex]

Hence, the results of the order of operations are:

[tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]

Answer:

i. Minimum is 343 square feet

ii. Maximum is 360 square feet

Step-by-step explanation:

The dimension of the rectangular garden plot is 12 feet by 28.6 feet.

1. The minimum possible area can be determined by;

area of a rectangle = length x width

                               = 28.6 x 12

                               = 343.2

The minimum possible area is about 343 square feet.

2. The maximum value can be determined by;

             28.6 ≅ 30.0 (1 sf)

area of a rectangle = length x width

                                = 30 x 12

                                = 360

The maximum possible area is about 360 square feet.

264 cm³

The volume of the figure 264 cubic centimeters.

"It is a three-dimensional solid shape which has six faces that are rectangles."

V = l w h, where l is the length, w s the width and h is the height of the  rectangular prism.

Given figure consists of two rectangular prisms.

For the smaller rectangular prism,

length(a) = 8 [tex]V_2= 8\times 5\times 5[/tex]cm, width(b) = 8 cm and height(h) = 1 cm

For the larger rectangular prism,

length(p) = 8 cm, width(q) = 5 cm and height(r) = 5 cm

Let [tex]V_1,V_2[/tex] represents the volume of the smaller and larger rectangular prisms respectively.

The volume of the smaller rectangular prism would be,

⇒ [tex]V_1=a\times b\times c[/tex]

⇒ [tex]V_1=8\times 8\times 1[/tex]

⇒ [tex]V_1=64[/tex] cu.cm.

The volume of the larger rectangular prism would be,

⇒ [tex]V_2=p\times q\times r[/tex]

⇒ [tex]V_2=8\times 5\times 5[/tex]

⇒ [tex]V_2 = 200[/tex] cu.cm.

The volume of the figure is:

= [tex]V_1+V_2[/tex]

= 64 + 200

= 264 cubic centimeters

The volume of the figure 264 cubic centimeters.
