Answer:

One solution which is x = 2

Step-by-step explanation:

Equations like these most often won't have more than one solution unless they are the exact same equation.

If the equation was x + 1 = x + 1, it would have infinitely many solutions because both sides are the same.

Equations with absolute value and quadratic equations most often have 2 solutions have there is a negative answer and a positive answer.

Answer:

the conversion factor

Step-by-step explanation:

The value of the longest of the four side lengths is 26 feet.

Let the integers be x, x + 2, x + 4 and x + 6.

Since the perimeter is given as 92 feet. This will be:

x + x + 2 + x + 4 + x + 6 = 92

4x + 12 = 92

Collect like terms

4x = 92 - 12

4x = 80

Divide

x = 80 / 4

x = 20

The longest side will be:

= x + 6.

= 20 + 6.

= 26 feet.

They have to drive 200 miles before Lena and Peter pay the same price for the rental .

In the question ,

it is given that ,

let x be the number of miles they drive together and pay the same amount.

the charge for Lena's car rental company is $50 per day and then $0.40 per miles which is represented by the equation

Cost = 50 + 0.40x

the charge for Peter's car rental company is $70 per day and then $0.30 per miles which is represented by the equation

Cost = 70 + 0.30x

Equating the cost for Lena and Peter car rental company

70 + 0.30x = 50 + 0.40x

0.40x - 0.30x = 70 - 50

0.10x = 20

x = 20/0.10

x = 200

None of the two graphs in this problem represents proportional relationships, as pairs of (input,output) have different ratios in each case.

A proportional relationship is modeled as follows:

y = kx.

Then the constant is given by:

k = y/x.

A relationship will be proportional only if for all points of the relationship, the constant k assumes the same value.

Two points of the relation between height and days are:

(30,10) and (50,20).

The constants are:

Different constants, hence not proportional.

For the second graph, the different constants are 2/2 and 2/3, as the two points of the second graph on the image at the end of the answer are:

What is the parabola equation?

A parabola is a graph of a quadratic function. An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively.

Given points are (-4,0), (3,0), and (2,-18).

The equation of a parabola is [tex]y = \frac{1}{4 \left(f - k\right)} \left(x - h\right)^{2}[/tex]

Since the point (−4,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(-4 - h\right)^{2} + k[/tex]

Since point (3,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(3 - h\right)^{2} + k[/tex]

Since point (2,−18) lies on the parabola, then [tex]-18 = \frac{1}{4 \left(f - k\right)} \left(2 - h\right)^{2} + k[/tex]

Solving the above all three systems, we get that [tex]h= -\frac{1}{2} , k = - \frac{147}{4}, f = -\frac{110}{3}[/tex]

Step-by-step explanation:

Answer:

x = -13 ± (√ 565) / 22 is the solution to the operation

(8x² + 8x - 9) + (3x² + 5x) = 0.

 ∴ (8x² + 8x - 9) + (3x² + 5x) = 0

=> 8x² + 8x - 9 + 3x² + 5x = 0

=> 11x² + 13x -9 = 0

After obtaining the standard form a, b and c are identified from the original equation and are placed into the quadratic formula.

∴ x = (-b±√(b²-4ac))/(2a)

11x² + 13x -9 = 0

where,

a = 11, b = 13, c = -9

=> x = (-13 ± √(13² - 4×11(-9)) )/ (2×11)

=> x =( -13 ± (√ 565) )/ (22).

So, the solution to (8x² + 8x - 9) + (3x² + 5x) = 0 is x = -13 ± (√ 565) / 22.

The graph of f(x) = 3x + 4 and h(x) = f(x + 3) are attached.

An equation is an expression that shows the relationship between two or more numbers and variables.

A linear function is represented as:

y = mx + b

Where m is the slope (rate of change) and b is the initial value of y.

f(x) = 3x + 4

h(x) = f(x + 3) = 3(x + 3) + 4 = 3x + 9 + 4

h(x) = 3x + 13

If the car's speed is 65 kilometers per hour, if it possible that the bus speed 75 kilometers per hour it is not possible.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

if the car's speed is 65 kilometers per hour, if it possible that the bus speed 75 kilometers per hour

Time = 2 hours

Distance = speed x time

Distance(for car ) = (65)(2) = 130 km

Distance(for bus ) = (75)(2) = 150 km

Total distance = 130 + 150 = 280 km

The area of the square is increasing at a rate of 36 cm/s2.

What is the rate of expansion of a solid?

For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for the thermal expansion of solids in daily life.

A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.

Calculation

L = length of a side

A = L2

dA/dt = 2L dL/dt

dL/dt = 2 cm/s

A = 81 sqcm ⇒ L = √A = √81 cm = 9 cm

dA/dt = 2(9cm)(2 cm/s) = 36 sqcm

Hence the rate is the area of the square increasing is 36sqcm

Using the rate of change of area ,

If the area of a square is 81 cm² the area of the square increases at a rate of 36 cm²/s.

Suppose that initially there were no squares, but suddenly squares began to form at a constant rate. At the end of the first second, the sides were 2 cm long each, and at the end of the second second they were 4 cm each. Therefore, we can say that the rate of change of increasing sides is 2 cm/s. If a square has a side of S cm, this is expressed mathematically.

dS/dt = 2 cm/s ---(1)

Since we know the area of the square is given by

A=S² cm²

the derivative of the area function shows the variation of area with respect to side S

dA/dS=2S

So , when area of square is 81 cm² , its side length is 9 cm. Since we need rate of change of area w.r.t. time, we need to multiply both the sides by dS/dt .

dA/dS×dS/dt=2S×dS/dt

=> dA/dt=2S×dS/dt

=> dA/dt = 2×9 ×2 = 36 cm²/s

Hence, the required area increasing rate is 36 cm²/s.
