Step-by-step explanation:

Answer:

infinitely many solutions

Step-by-step explanation:

The two sides of this equation are identical.  Thus, this is an 'identity.'  The equation will be true no matter what value is substituted for x.  Thus, there are infinitely many solutions.

Answer:

The geometrical relationships between the straight lines AB and CD is that they have the same slope

Step-by-step explanation:

Given

[tex]OA = 2x + 9y[/tex]

[tex]OB = 4x + 8y[/tex]

[tex]CD = 4x - 2y[/tex]

Required

The relationship between AB, CD

Since AB is a straight line and O is the origin, then:

[tex]AB = (c - a)x + (d - b)y[/tex]

Where:

[tex]OA = ax + by[/tex] ====> [tex]OA = 2x + 9y[/tex]

[tex]OB = cx + dy[/tex] ====> [tex]OB = 4x + 8y[/tex]

This implies that:

[tex]a =2[/tex]      [tex]b = 9[/tex]     [tex]c = 4[/tex]   [tex]d = 8[/tex]  

So:

[tex]AB = (c - a)x + (d - b)y[/tex]

[tex]AB = (4 - 2)x + (8 - 9)y[/tex]

[tex]AB = 2x -y[/tex]

So, we have:

[tex]AB = 2x -y[/tex]

[tex]CD = 4x - 2y[/tex]

Calculate the slope (m) of [tex]AB\ and\ CD[/tex]

[tex]m = \frac{Coefficient\ of\ y}{Coefficient\ of\ y}[/tex]

For AB

[tex]m_1 = \frac{-1}{2}[/tex]

[tex]m_1 = -\frac{1}{2}[/tex]

For CD

[tex]m_2 = \frac{-2}{4}[/tex]

[tex]m_2 = \frac{-1}{2}[/tex]

[tex]m_2 = -\frac{1}{2}[/tex]

By comparison:

[tex]m_1 = m_2 = -\frac{1}{2}[/tex]

This implies that both lines have the same slope

Answer:

Step-by-step explanation:

if their similar then find the proportion with a cross multiplication equation

x/36 = 13/39

x*39 = 36*13

39x = 468

x = 468/39

x = 12

Answer:

x = 12

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{JL}{PQ}[/tex] = [tex]\frac{JK}{PR}[/tex] , substitute values

[tex]\frac{x}{36}[/tex] = [tex]\frac{15}{45}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

The use of the addition property of equality is sound, and the answer is correct

Step-by-step explanation:

Addition Property of Equality

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.

The function that best models the situation is f(x) = 23540(0.95)ˣ, where x is the number of years.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given that, Andy buys a new car for $23,540. He estimates that the new car will decrease in value by about 5% each year.

The depreciation rate =

A = P(1-r)ⁿ

Where, A = amount final

P = initial amount

r = rate and n = number of the years

Therefore,

The depreciation rate =

f(x) = 23540(1-0.05)ˣ

f(x) = 23540(0.95)ˣ

Hence, the function that best models the situation is f(x) = 23540(0.95)ˣ, where x is the number of years.

Answer:

6.5 hours

Step-by-step explanation:

James troubled 40 miles per hour and traveled a total distance of 260 miles

The formula to calculate the Total Amount of time it would take to reach the destination bis given as:

Time = Distance/Speed

Distance = 260 miles

Speed = 40 miles per hour

Hence,

Time = 260 miles/40 miles per hour

Time = 6.5 hours

Therefore, the total amount of time it took James to reach his destination is 6.5 hours

Answer:

x = 2.

Step-by-step explanation:

y = k/x

11 = k/1

so k = 11

y = 11/x

When y = 5.5:

5.5 = 11/ x

x = 11/5.5

= 2.

The values of x and y vary inversely, if the value of y is 5.5 then the value of x will be equal to 2.

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the information provided in the question,

y = k/x

11 = k/1

k = 11

y = 11/x

If y = 5.5,

5.5 = 11/ x

x = 11/5.5

x = 2.

Step-by-step explanation:

Answer:

B. ∆XYZ, in which m∠X = 10° and m∠Z = 25°

Step-by-step explanation:

∆ABC

m∠A = 10°

m∠B = 145°

m∠C = 180° - (m∠A + m∠B )

= 180° - (10° + 145°)

= 180° - 155°

m∠C = 25°

∆XYZ

m∠X = 10°

m∠Z = 25°

m∠Y = 180° - (m∠X + m∠Z)

= 180° - (10° + 25°)

= 180° - 35°

m∠Y = 145°

so,

m∠A = m∠X = 10°

m∠C = m∠Z = 25°

m∠B = m∠Y = 145°
