Slope = 1.75; (10, 16.5)

Answers

Do you want the equation of the line given the slope and a point it goes through?

y - y1 = m (x - x1)
y - 16.5 = 1.75 (x - 10)
y - 16.5 = 1.75x -17.5
y = 1.75x - 1

A system of equations is shown below.
y = 1.5x - 3
y = 1.5x + 4

Which statement is true about the system
A the system has no solution
B the solution has infinitely many soulutions
C the system has exactly one solution and it’s (0,-3)
D the system has exactly one solution and it’s (6,4)

Answers

Given:

The system of equations is

[tex]y=1.5x-3[/tex]

[tex]y=1.5x+4[/tex]

To find:

The true statement about the given system of equations.

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is the slope and b is the y-intercept.

We have,

[tex]y=1.5x-3[/tex]

[tex]y=1.5x+4[/tex]

On comparing these two lines with slope intercept form, we get

[tex]m_1=1.5,b_1=-3[/tex]

[tex]m_2=1.5,b_2=4[/tex]

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

Therefore, the correct option is A.

The area of the polynomial is 35 square unit.

Step-by-step explanation:

It is given that area of the polygon WXYZ with its vertices at W(–3, –2), X(–3, 5), Y(2, 5), and Z(2, –2)

From the below graph it is noticed that the given polynomial is a rectangle with length 5 and width 7

The distance formula

Using the above formula we get,

The length of opposing sides are equal

Using the Pythagoras theorem, the length of diagonal WY and XZ are

Since the length of the diagonal are same, therefore the given polygon is a rectangle.

The area of a rectangle is

Where l is length and w is width.

The area of given polynomial is

Therefore the area of the polynomial is 35 square unit.

find the common ratio of the geometric sequence

Answers

Step-by-step explanation:

the formula to find common ratio is

r= second term/first term

The common ratio of the given the geometric sequence is -0.3

What is a geometric sequence?

A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Given that, a geometric sequence, is -162,54,-18.6,... we need to find the common ratio,

In a standard geometric sequence, a₁, a₂, a₃, a₄, a₅..... the common ratio is given by :-

a₂ / a₁ = a₃ / a₂ .... = r

Here, r = -54/162 = -18.6/54 = -0.3

Hence, the common ratio of the given the geometric sequence is -0.3

Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = [tex]5\sqrt5[/tex], this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle [tex]\sqrt5[/tex] times larger than the corresponding side on the small triangle. That means AB is [tex]\sqrt5[/tex] times larger than BC as well. So multiply BC by [tex]\sqrt5[/tex] get us the answer.
