Answer:

4m + 5

Step-by-step explanation:

product of 4 and m: 4m

5 more than the product of 4 and m: 4m + 5

Answer: 4m + 5

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:

Subtraction

Step-by-step explanation:

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

We can look at the line graph, and look at the "1" at the bottom, then go up to where the line is. It's at the point "15". The unit rate is 15 words per minute.

Answer:  Noah's mixture would be more flavorful and fizzy because his ratio of water and fizz powder aren't to off (not a large ratio gap). Andre's orange fizz would be a little more watered down making it less fizzy and less flavorful because 8 cups were added instead of 6 or 7 cups of water. Also Noah would have less drink made them Andre because he only used 6 cups of water.

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:

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:

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:

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

Answer:

$93.50

Step-by-step explanation:

Ok so divide $10.00 by 2 which is $5.00 and divide $5.50 by 2 which is $2.25 and divide $15 by 2 which is 7.50. Since there was 4 adults so it cost $20.00 because 5.00X4=20.00. Since there was 16 kids going it cost $36.00 because $2.25X16=36. Since they were there for 5 hours it cost $37.50 because $7.50x5=$37.50. Add all of those up and you will get $93.50.

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:

Step-by-step explanation:

If the unit cost is given by the function C(x)=0.5x^2-330x+65,738 where x is the amount of engines made while C(x) is the unit cost. In order to know the amount of engine needed to minimize the cost;

we will first find dC/dx and equate the resulting function to zero to get x.

dC/dx = 2(0.5)x - 330

dC/dx = x - 330

since dC/dx = 0

x - 330 = 0

x = 330 (critical point)

Then find the second derivative to check if it is greater than zero.

d²C/dx² = 1

Since d²C/dx² > 0, then the cost will be at the minimum when x = 330

Substitute x = 330 into the modeled function;

C(330)=0.5(330)^2-330(330)+65,738.

C(330)= 54,450-108,900+65,738.

C(330)= -54,450+65,738.

C(330)= 11,288

Hence the amount of engines that must be made to minimize the unit cost is 330 engines and the unit cost at the minimum price is 11,288

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

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.
