Answer:

Given equation: mx =5           ......[1]

To find for which values of m does the given equation have a single solution.

Divide equation [1] both sides by x,

\frac{mx}{x} = \frac{5}{x}

Simplify:

m = \frac{5}{x}

The value of m have a single solution for all real values of x except x≠0.

No solution states that there is no answer to the equation

Infinite solutions  states that any value for the variable would make the equation true.

we can write equation [1] as;

x= \frac{5}{m}

For the value of m = 0 , the given equation does not have solutions.

For any constant parameter m ,

x=\frac{5}{m}, the given equation does not have any infinite number of solutions.

<u>Corrected Question</u>

The blueprint for the Moreno Moreno​'s living room has a scale of 2 inches equals 7 feet.The family wants to use a scale of 1 inch equals = 6 feet. What is the width of the living room on the new​ blueprint? A rectangle is labeled width = 12 inches.

Answer:

7 Inch

Step-by-step explanation:

The width of the room on the old blueprint = 12 Inches

<u>Scale on the old blueprint: </u>

2 inches = 7 feet.

Therefore: 1 Inch =7/2 feet

12 Inches =12 X 7/2 feet =42 feet

The actual width of the room is 42 feet.

<u>Scale on the new blueprint</u>

1 inch equals = 6 feet; which we can reorder as:

6 feet=1 inch

1 feet =1/6 Inch

Therefore:

42 feet = 42 x 1/6 Inch =7 Inch

Thus, the width of the living room on the new​ blueprint is 7 Inch.

A pile of earth removed from an excavation is a cone measuring 6ft high and 30ft across its base. How many trips will it take to
nignag [31]

Answer: 14

Step-by-step explanation:

Given

Excavation cone measures

height h=6\ ft

Diameter d=30\ ft

Truck can dump 125\ ft^3 at a time

The volume of a cone is

V=\dfrac{1}{3}\pi r^2h

Putting values

\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3

No of trips(N) required to accumulate this much volume is given by

\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14

Therefore, 14 trips are necessary to accumulate a cone of volume 1414\ ft^3

Write a recursive rule for the sequence. Assume it starts with the 1st term. 10, 14, 18, 21...
Papessa [141]

Option D is correct. The correct option for the recursive formula is f(0) =6;f(n)=f(n - 1)+4

Given the sequence 10, 14, 18...

The first term is 10, hence

a1 = 10

The previous terms will be a_{n-1}

From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

a_n = a_{n-1} + 4

Get the term before the first term a_0

If n = 1

a_1 = a_{1-1} + 4\\a_1 = a_{0} + 4\\a_0=a_1-4\\a_0=10-4\\a_0=6

Hence the correct option for the recursive formula is f(0) =6;f(n)=f(n - 1)+4
