the answer is B,
first we have to multiply the -3 through the parenthesis, get in -3x+9, then distribute 5 through the parenthesis, get in 5-5x
then you have to collect like terms, get in -3x+5x<5-9, it gives 2x<-4
then divide 2 in both sides, and you get the answer B

Answers

A basis for the eigenspace corresponding to a = 11 is (1, -2, 0) and a basis for the eigenspace corresponding to a = 2 is (0,1,1).

An eigenspace is the set of all vectors that are multiplied by a matrix and remain unchanged. In this case, the eigenspace is the set of all vectors that when multiplied by the matrix A will result in a vector with a scalar multiple of the eigenvalue. The eigenvalue is found by solving the characteristic equation, which is the determinant of the matrix minus the eigenvalue multiplied by the identity matrix.

For the matrix A, the eigenvalues are 11 and 2. The corresponding eigenspace for each eigenvalue is then found by solving the homogeneous system of equations. For a = 11, the solution to the system is (1, -2, 0) and for a = 2, the solution is (0,1,1). Both of these vectors form a basis for the corresponding eigenspaces.

Which statement BEST explains why the slope of each line segment formed by the hypotenuse of each triangle is the same?
A)
The triangles are similar.
B)
The triangles are congruent.
C)
The triangles share a point.
D)
The triangles are right triangles.

Answers

Answer:

Step-by-step explanation:

Two triangles can be similar if their leg lengths are in proportion with each other, regardless of size. Since the triangles are the same in different sizes, they are similar. The hypotenuse of the triangles isn't the same, but the angles are the same, so the hypotenuse will still follow the same line.

Completing the square – can be used to solve any quadratic equation. It is a very important method for rewriting a quadratic function in vertex form. Quadratic formula – is the method that is used most often for solving a quadratic equation.

What is equation?

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Does the point (2,-1) lie on the line
y=3-2x?

Answers

Answer:

yes

Step-by-step explanation:

the line passes through that point.

Answer:

yes

Step-by-step explanation:

Here, x=2 and y=-1

If these points lie on the line y= 3-2x,then they must satisfy the equation of the line (also mean they must be equal)

So on solving the equations putting the value of x and y, we get

y=3-2x

or,-1=3-2*2

or,-1=3-4

Therefore, -1=-1

Answers

The measure of convex arc upper Z is 243⁰ Option D

How to find the measure of the angle?

We should be aware that a convex angle is the angles that are irregular in nature

Assume that the radius of the given circle is r.

The central angle of the lower arc ZWX = 41+180 = 221⁰

Note that then central angle of the upper arc ZWX = 360- 221⁰

This implies that the central angle of the upper arc ZWX = 360-221 = 139⁰

Recall that Lenght of arc = A/360 *2*π*r

Where A is the angle made by the radii, r= radius of the circle

Arc length of upper ZWX:

Arc length of upper ZWX = 139π/180*r

Arc length of upper ZWX = 139πr/180

The lenght is (139*22)/ 180*7

= 3058/2360

= 245⁰

In conclusion the measure of the convex upper is 245⁰

What is the slope-intercept form of a line?

The slope-intercept form of a line is represented by y=mx+c where m=slope and c is the y-intercept of the line

Given here: The line 3x+5y=15 , Rearranging in the slope intercept form we get y=-3x/5+3 and thus slope of the line that is perpendicular to this line must be equal to 5/3 and it passes through (3,2) then we get the equation of the line as y=5x/3+c and putting (3,2) in the equation we get the value of c as c=-3

∴ The equation of the line is y=5x/3-3

Answers

Answer:

Step-by-step explanation:

Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3

The cheerleader section is on the basketball court. Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards. How many square yards of floor space are taken up by one row of cheerleaders? Help!

Answers

Answer:

The area of the floor space is equal to 5.83 sq yards.

Step-by-step explanation:

Given that,

Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards.

We need to find how many square yards of floor space are taken up by one row of cheerleaders.

We know that, the area of a rectangle is given by :

A = lb

So,

[tex]A=\dfrac{7}{4}\times \dfrac{10}{3}\\\\A=5.83\ yards^2[/tex]

So, the area of the floor space is equal to 5.83 sq yards.

On the first part of a journey, a motorcyclist travels for 3 hours at an average speed of 80 km per hour. On the second part of a journey, the same motorcyclist travels for 90 minutes at an average speed of 90 km per hour. How far does the motorcyclist travel in total?

Answers

Answer:

375 km

Step-by-step explanation:

distance = speed * time

3 hours at an average speed of 80 km per hour

distance = 3 * 80 = 240 km

90 minutes at an average speed of 90 km per hour

90 min = 1.5 hours

distance = 1.5 * 90 = 135 km

Total distance = 240 + 135 = 375 km

The moon orbits earth at 384400km. The distance from earth to the sun is 149600000km. The diamiter of the sun is 1391000km. What would the diamiter of earth have to be to appear the same size as the sun from the moon if the celestial objects are in the order shown here : Sun, earth, moon.

Answers

Answer:

The diameter of Earth that would appear the same size as the Sun from the Moon is approximately 54304839.858 kilometers

Step-by-step explanation:

To find the diameter of Earth that would appear the same size as the Sun from the Moon, we need to know the distance from the Moon to the Sun and the distance from the Moon to Earth.

Since the distance from the Moon to the Sun is much greater than the distance from the Moon to Earth, the angle subtended by the Sun at the Moon will be much smaller than the angle subtended by Earth at the Moon.

Therefore, the size of Earth as seen from the Moon will be much larger than the size of the Sun as seen from the Moon.

To find the ratio of the size of Earth to the size of the Sun as seen from the Moon, we can use the formula:

size ratio = (distance to Earth / distance to Sun) x (Sun's diameter / Earth's diameter)

Substituting in the given values, we get:

size ratio = (384400km / 149600000km) x (1391000km / Earth's diameter)

Simplifying, we get:

size ratio = 0.00257 x (1391000km / Earth's diameter)

To find the diameter of Earth that would appear the same size as the Sun from the Moon, we need to solve for Earth's diameter. Dividing both sides of the equation by 0.00257, we get:

Earth's diameter = (1391000km / 0.00257) = 54304839.858km

Therefore, the diameter of Earth that would appear the same size as the Sun from the Moon is approximately 54304839.858 kilometers.
