Answer:

1. 2(x - 5) = 2(x - 5) has infinitely many solutions

2. 5(x + 4) = 5(x-6) has no solution

3. 5(x + 4) = 3(x-6) has one solution

4. 4(x - 2) = 4(x + 2) has no solution

5. x + 2(x - 5) = 3(x - 2) - 4 has infinitely many solutions

Step-by-step explanation:

I did the assignment and I got it correct edge2020

1. 2(x-5)= 2(x-5) = Infinitely many solutions.

2. 5(x+4) = 5(x-6) =  No solution

3. 5(x+4) = 3(x-6) =  One solution

4. 4(x-2) = 4(x+2) = No solution

5. x+2(x-5) = 3(x-2) - 4 = Infinitely many solution

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

The given equations is;

1. 2(x-5) = 2(x-5)

2x-10 = 2x-10

0=0

Hence, This equation has infinitely many solution

2. 5(x+4) = 5(x-6)

5x+20 = 5x-30

20 ≠ (-30)

Thus, This equation has no solution

3. 5(x+4) = 3(x-6)

5x+20 = 3x -18

5x-3x = -20-18

2x = -38

x=-19

Thus ,this equation has one solution

4. 4(x-2) = 4(x+2)

4x-8 = 4x+8

-8 = 8

Thus, this equation has no solution

5- x+2(x-5) = 3(x-2) -4

x+2x-10 = 3x-6-4

3x-10 = 3x-10

0=0

Thus, this equation has infinitely many solution

Answer:

y[tex]\geq 2.2[/tex]

Step-by-step explanation:

John wants to complete at least 100 miles. he has completed 12 which means he only has 88 left. If you divide 88(miles left) by 40(time left) you get 2.2 miles. so he would need a minimum of 2.2 miles a day to bike 100 miles.

Step-by-step explanation:

The graph should start with an y-intercept of 100 because even if zero people attend, it costs $100 for the DJ. Then, the line should have a slope of 20 because for each additional person it costs another $20. when you reach the point (10,200) the line will plateau where every y value after that will be 200

Step-by-step explanation:

Answer:

y = -15x - 3.04

Step-by-step explanation:

1) First place down what you are given.

Y = a(x - p) (x - q)

2) Then Substitute.

a = -16

p = -0.12

q = 1.12

y = (-16)(x - (-0.12))(x - (1.12)

3) Do order of operations (PEMDAS)

y = (-16)(x + 0.12)(x - 1.12)

Now distribute

y = − 16 x  −  1.92 + (x - 1.12)

y = -16x - 1.92 + x - 1.12

y = -16x + x - 1.92 - 1.12

y = -15x - 3.04

4)

You answer is:

y = -15x - 3.04

Answer:

to find the rate of fencing, you should find the perimeter of the rectangle.

2(l+b)

2(155+125)

2*180

360m

cost of fencing = 360*10

= Rs 3600

now to find the cost of fielding, find the area

(l*b)

155*125

19375 square mtr

cost of fielding = 19375*15

= Rs 290625

Answer:

0.384615

Step-by-step explanation:

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation is

y = - 2x - 1

Comparing with the general equation above

Slope = - 2

Y - intercept = - 1

Answer:

x = -3970, g = 2015

Step-by-step explanation:

Solve this system of linear equations by substitution:  substitute 2g + 60 for x in the first equation.

Then we have:

3g - 2(2g + 60) = -2135

Performing the indicated multiplication, we get:

3g - 4g - 120 = -2135, or

     -g             =    -2015

Then g = 2015.  Then x = 2(-2015) + 60, or x = -3970

The solution is x = -3970, g = 2015

Option B is the correct answer, x+15=41

Answer:

x = 13

y = 20

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached.

In line geometry, the oppositely directed angles are equal. According to the diagram shown;

4x = 6x - 26 (oppositely directed angles)

We can get the value of x from the equation as shown;

4x = 6x - 26

Subtract 6x from both sides

4x-6x = 6x-6x-26

-2x = -26

x = -26/-2

x = 13

Similarly:

6y+8 = 7y-12 (oppositely directed angles)

collect like terms

6y-7y = -12-8

-y = -20

multiply both sides by -1

-(-y) = -(-20)

y = 20

Hence x = 13 and y = 20

Answer:

Subtraction

Step-by-step explanation:

This is because you would minus 3 from both sides, leaving:

2x=8

Then, you would divide both sides by 2 to isolate x.

x=4

Answer:

The third option, or (x, y) ---> (x + 4, y - 3)

Step-by-step explanation:

When moving right on the horizontal axis, you always add so since we are moving 4 units to the right, that would be x + 4, and when moving down on the vertical axis, we always subtract, so since we are moving 3 units down, that would be y - 3

Answer: D

Step-by-step explanation:

Ten thousandths is the fourth place

The expression one hundred seventy-five ten-thousandths in the standard form will be 175,000. The correct option is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.  

Given that the number is one hundred seventy-five ten-thousandths. The standard form of the number can be written as below,

Standard form = one hundred seventy-five ten-thousandths

Standard form = 175,000

Hence, the standard form is 175,000.
