Answer: no solution

Step-by-step explanation:

Correct, there is no solution as any values of x and y will make the equation false

a) The number of intersections between the railroad and the highway is of: One.

b) The number of intersections between the railroad and the turnpike is of: Two.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which the parameters are listed as follows:

The points for the railroad are given as follows:

(-8, 0) and (0,5).

When x = 0, y = 5, hence the intercept is of:

b = 5.

When x increases by 8, y increases by 5, hence the slope is of:

m = 5/8.

Thus the equation for the railroad is of:

y = 5/8x + 5.

Then the number of intersections with the highway is of one, as they are linear functions with different slopes.

With the turnpike, the intersection is given as follows:

5/8x + 5 = x²/3

x² -1.875x - 15 = 0.

The discriminant is of:

(-1.875)² - 4(1)(-15) = 63.5.

Which is positive, hence they have two intersections.

The 56th term of the following arithmetic sequence 7,10,13,16 is 172.

What is the arithmetic sequence?

A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms.

Here, we have

Given

Arithmetic sequence 7,10,13,16.

We have to find the 56th term.

The common difference between terms: 10 - 7 = 3

Using the arithmetic progression formula:

nth term = first term + (n-1)* common difference

56th term = 7 +(56-1) 3

56th term = 7 + 55×3

56th term = 7 + 165

56th term = 172

Answer: The Commutative Law of Addition states that the order in which numbers are added does not affect the result. This means that for any two numbers a and b, we have a + b = b + a.

We can use the Commutative Law of Addition to rewrite the equation 177 + 563 = 740 as follows:

177 + 563 = 740

563 + 177 = 740

Both of these equations are equivalent to the original equation, because they represent the same mathematical statement.

Note that in the first equation, we simply reordered the terms of the original equation. In the second equation, we added the numbers in a different order, but the result is still the same.

The other equations you provided are not equivalent to the original equation and do not use the Commutative Law of Addition.

The required expression for the term of the given sequence is aₙ = 625 × (1/5)ⁿ⁻¹.

In order to check a geometric sequence, find the ratios of the consecutive terms of the given sequence. If they are equal, the given sequence is geometric.

The given sequence is as follows,

625, 125, 25, 5, 1

The first term is given as a₁ = 625

And, the ratio of the consecutive terms are,

125/625 = 1/5

25/125 = 1/5

Since the ratio of two consecutive terms are equal, the given sequence is a geometric sequence.

The nth term of a geometric sequence is given as aₙ = a₁rⁿ⁻¹.

Thus, the expression for the given sequence is aₙ = 625 × (1/5)ⁿ⁻¹.

Hence, the term for the given sequence can be written in general form as  aₙ = 625 × (1/5)ⁿ⁻¹.

The value of x in the intersecting line is 54.

When lines intersect, angle relationships are formed such as vertically opposite angles, linear angles angles on a straight lines.

Therefore, angle 2x + 2 is vertically opposite to the angle 3x - 52 .

Vertically opposite angles are congruent to each other.

Vertical Angles are the angles opposite each other when two lines cross. in other words, vertical angles are formed when two lines meet each other at a point.

Hence,

2x + 2 = 3x - 52

2x - 3x = -52 - 2

X is the amount of the 20% saline solution

Y is the amount of the 40% saline solution

The interest rate would be 13%.

What is the simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest. For example, when a person takes a loan of Rs. 5000, at a rate of 10 p.a. for two years, the person's interest for two years will be S.I. on the borrowed money.

To find the interest rate, we can use the formula for simple interest:

I = Prt

where I is the amount of interest earned, P is the principal (the initial amount of money deposited), r is the interest rate, and t is the time in years.

In this case, we know that I = $3,900, P = $10,000, and t = 3 years. We can use this information to solve for r:

I = Prt

$3,900 = $10,000r3

r = $3,900/($10,000*3)

r = 0.13 or 13%

Horizontal compression of f(x) = -x + 4 by a factor of 0.5 will be -2x + 4.

A horizontal line that a function's graph looks to coincide with but does not really do so is said to be its horizontal asymptote. The final behavior of the function is determined using the horizontal asymptote.

Given, g(x) is a horizontal compression of function f(x) = - x + 4 by a factor of 0.5. Hence,

g(x) = -x / 0.5 + 4

g(x) = -2x + 4

To be a triangle of three side polygon the sum of any two sides must be greater than the third side.

If we take 32 feet,21 feet, and 8 feet.

21 + 8 = 29 < 32 so it will not form any triangle.

Thus, 8 cannot be taken. now let's take 32,21 and 12 here 21 + 12 = 33 > 32 so it will form a triangle this will be used for the project.

The measure of Angle JKL mJ = 159.4°, mK = 3.8°, and mL = 16.8°.

A ray is rotated about its endpoint, or vertex, to create an angle. The rotational difference between a ray's starting and ending positions is what is measured by an angle's degree.

If x = mJ, y = mK, and z = mL, then

Angle L exceeds Angle K by thirteen, hence z = y + 13 is the result (1)

Since angle J exceeds angle K by a factor of 7, x = 7(6y) = 42y (2)

X + Y + Z = 180 because the triangle's angles add up to 180°.

In place of (1) and (2) (3).

42y + y + (y + 13) = 180

44y + 13 = 180

44y = 167

y = 3.8°

x = 42y = 159.4°

z = y + 13 = 16.8°

If the slope is negative, the function is downward-sloping because y falls off as x rises. If the slope is zero, y remains constant—a horizontal line—and does not vary.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

The bare minimum required is $4500 to reserve 5 blocks totaling at least 34 rooms.

In mathematics, a relationship between two expressions or values that are not equal to each other is called "inequality".

Here,

The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:

n ≥ 50

Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:

B ≥ 34

Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:

a ≥ 5

Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:
