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:

x=8

Step-by-step explanation:

If the triangle is isosceles, it means that 2 of its sides are equal in length, therefore its perimeter is equal to

[tex](2x - 3) + (2x - 3) + (x)[/tex]

Adding similar terms, and recalling that the perimeter is equal to 34, we get

[tex]5x - 6 = 34 \\ 5x = 40 \\ x = 8[/tex]

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:

-1

Step-by-step explanation:

The coefficient is the number directly next to a given variable (typically 1 if there is no given number).

In this case, note the variable: -x

As stated above, the number is 1 if there is no number given. However, note that there is a negative sign, therefore, your coefficient is -1

-1 is your answer.

Answer:

7 cm by 6 cm by 18 cm

Step-by-step explanation:

Given :

Volume of candle = 270cm³

Height = 18cm

Triangular base = 5cm

Width of candle = 7cm

Volume = Area of base * height

270cm³ = Area of base * 18

Area of base = 270cm³ / 18cm

Area of base = 15 cm²

Using this to find the height of triangular prism :

Area = 1/2 * base * height

15cm² = 1/2 * 5 * height

15cm² = 2.5 *. Height

Height = 6 cm

Hence, the dimension of triangular prism is : 7cm by 6cm by 18cm

Answer:

12

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:

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:

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°

Answer:

C And D!

Step-by-step explanation:

Answer: I think it’s A (x + 4 = 14) I’m not sure though

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.
