The two lines y=4x+5 and y= 4x-2 are parallel because their slopes are equal (both equal to 4).What happens when you try to algebraically solve for their intersection point?

Answer:

-4b^3 + 7b - 7

Step-by-step explanation:

We have to look at terms which look like each other, for example 1b and 6b.

We can add and subtract terms which have the same degree of b.

In this question, we can safely add -1 and -6, and also b and 6b,

which gives us (-4b^3 + b - 1 ) + 6b - 6) = -4b^3 + (1+6)b +( -1 - 6) = -4b^3 + 7b - 7

The three remaining terms all have different degrees of b's (respectively 3, 1, 0), so we can't add those up any further, which tells us that this is the right answer.

A easy way to operate fractions is convert the integer in a fraction, to operate fractions with the same denominator:

Answer:

-0.5,-1/5,0.7,3/4 its correct

Answer:

-0.5, -1/5, 0.7, 3/4

Step-by-step explanation:

We can convert the fractions into decimals.

-1/5 = -0.2

3/4 = 0.75

-0.5 is the least, then -1/5, then 0.7, and lastly 3/4.

Hope this helps!

P.S, Can I get a brainliest if this is right? Thanks!

In order to find the value of x, consider that triangles PQR and PST are similar. Then, you have the following equivalence:

PQ/PS = PR/PT

Where:

PQ = x

PS = 45m

PR = 16m

PT = 36m

replace the previous values of the length of the segments and solve for x, just as follow:

x/45 = 16/36 multiply by 45 both sides

x = (16/36)45

x = 20

Hence, the value of x is x = 20

The area of a square inscribed in a circle of a radius square root 70 is 140 units².

A square is inscribed in a circle if its four vertices are on the circle's circumference. When a square is inscribed in a circle, the diameter of the circle must be equivalent to the diagonal of the square

Given:

The radius of the circle = √70 units

Let the side of the square inscribed in the circle be x units.

Diagonal of the square = [tex]\sqrt{x^{2} + x^{2} }[/tex] = [tex]\sqrt{2} x[/tex]

Diameter of the circle = 2 × √70 ≅ 16.7 units

Now,

Diagonal of the square = Diameter of the circle

[tex]\sqrt{2} x = 16.7[/tex]

[tex]x = \frac{16.7}{\sqrt{2} }[/tex]

x ≅ 11.83 units

So, the Area of the square = (side)² = x²

                                     = (11.83)²

                                    ≅ 140 units²

The monthly deposit that is required to achieve the desired monthly yield at retirement is $1,056.71.

An annuity is a series of payment that is made over a period of time. The annuity in this question would last for 25 years. When an investment is compounded monthly, it means that the investment would grow at an exponential rate once in a month.

The formula that would be used to determine the monthly payment is:

Monthly payment = future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

By using the points (2, 30) and (4, 60) that we can see on the graph, we can see that the linear equation that models the data is:

y = 15*x

A general linear equation is of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), the slope is given by:

a = (y₂ - y₁)/(x₂ - x₁)

In this case we can use two points that appear on the graph, I will use the first two ones:

(2, 30) and (4, 60)

Then the slope is:

a = (60 - 30)/(4 - 2) = 30/2 = 15

Thus, the line is of the form:

y = 15*x + b

To find the value of b we use the point (2, 30), replacing these values we get:

30 = 15*2 + b

30 = 30 + b

30 - 30 = b

0 = b

We conclude that the linear equation that models the data is y = 15*x

The domain of the graph is [0,14] and the range of the graph is [0, 7]

In this question, we have been given a graph of height of a falling object.

In this graph, x-axis represents the time in seconds and y-axis represents the height in meters.

We know that, the domain of a graph consists of all the input values which are on the x-axis and the range is the set of possible output values, which are shown on the y-axis.

In this graph we can see that the input (time) takes the values between [0, 14] and the output (height) has values in the interval [0, 7]

Therefore, the domain of the graph is [0,14] and the range of the graph is [0, 7]

Congruent figures in geometry are identical in shape and size.

This means that two figures are congruent with each other even if they are rotated, flipped or trasnlated as long as they have the identical shape and size.

For example, look at the following picture

We notice that the triangle has the same size and shaped, hence they are congruent. Furthermore we can say that the side BC is congruent to the side ZY and so on.

Answer:

68

Step-by-step explanation:

1 foot = 12 inches

Multiply 5 by 12 inches

5 feet = 60 inches

Add the extra 8 inches

60 + 8 = 68 inches

George is 68 inches tall.

Answer:

Step-by-step explanation:

George is 5 feet and 1 foot equals 12 inches, so do 12x5 + the actual 8 inches

12x5=60

60+8=68 inches total

Notice that if a = 11 and b = 13 are two sides of the triangle, then:

since the larger side measures 25 units, then we cannot write a triangle with the given measures, since a + b cannot be less than the larger side. Therefore, it is not a triangle

Answer:

50 dress sandals

Step-by-step explanation:

Let D = number of dress sandals and C = number of casual sandals

Customers bought twice as many casual sandals as dress sandals. In algebraic form this would be

S = 2D  (number of casual sandals = 2 times number of dress sandals)

Since casual sandals sell for $12 each and dress sandals for $22 each, the total sales for S casual and D dress sandals

= 12S + 22D = 2300 (given)

Substitute S = 2D into the above equation to get
12 (2D) + 22D = 2300

24D + 22D = 2300

46D = 2300
D = 2300/46 = 0

Answer: Customers bought 50 dress sandals

The area of 1 1/2 meters wide and 2 meters long carpet is 3 meters².

As per the known fact, the area of rectangular object is calculated by performing multiplication of value of two sides. These two sides are length and width. Firstly converting width from mixed fraction to fraction -

Width = (2×1 + 1)/2

Width = 3/2 meters

Area = length × width

Keep the values in formula to find the value of area of rectangular flying carpet

Area = 3/2×2

Cancelling 2 as it is common in both numerator and denominator

Area = 3 meters²

Thus, the area of rectangular flying carpet is 3 meters².
