x^2 - 3 = 1

Please help me with this I need a answer and explanation so I can do this on my own asap!

Answer:

Let a two digit number be, 10x + y.

75% of the number is,

= 75 % of (10 x + y)

= 75/100 × (10x+y)

= 3/4 × ( 10x + y)

According to the question, When increased by 75%, The digits must be reversed.

So,

(10 x + y) + 3/4 ( 10x + y) = 10y + x

4 (10x + y) + 3 ( 10x + y) = 4 ( 10y + x)

7(10x + y) = 4(10y + x)

70x + 7y = 40y + 4x

70x - 4x = 40 y - 7y

66x = 33y

2x = y

So,

x = 1, y = 2, 10x + y = 12

x = 2, y = 4, 10x + y = 24

x = 3, y = 6, 10x + y = 36

x = 4 , y = 8 , 10x + y = 48

x can't be 5, as y will be 10 ( y should be a single digit).

Therefore, 4 two digit numbers are possible.

Answer:

x=49 exactly but a i forgot how to get range sry

Step-by-step explanation:

The given statement can be written as:

6+√-80

To solve √-80 re-write -80 as -1 * 80

Now √-80 =√-1 * 80

Now we can write it as:

6+ √-1 * √80

We know that √-1 = i

Thus it becomes:

6+ i√80

Now find the square root of 80

80 does not have a perfect square root

Its square root can be found as 80 = 4*4*5

Then,

6+i√4*4*5

Notice that 4 makes a pair.. So we will write it outside the square root

6+1*4√5

We will write it as:

6+4i√5

Thus the correct option is 6 plus 4 i times the square root of 5....

Assuming that (-2)(-7) and 4 + (-18) are equal.

Using the property [-x × -y = x × y = xy]:

Using the property [x + (-a) = x - a]:

Assuming that (2)(7) and 4 + 18 are equal.

Assuming that (–2)(7) and 18 + (–4) are equal.

Using the property [-x × y = -xy]:

Using the property [x + (-a) = x - a]:

Assuming that (2)(-7) and 4 - 18 are equal.

Using the property [-x × y = -xy]:

Therefore, Option D is correct.

it's base× height (same as a rectangle:

4×5=20

the triangle, 3, and right angle are there just to confuse you :)

area: 37.74 yds

you get this by multiplying the length and width

perimeter: 25 yds

you get this by adding up the length of each side

The answer will be option B. The y-values are all greater than or equal to 2.

A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Here no matter what x is, y will always be positive, because the absolute value of x-5 will always be positive. The smallest value that y can be is when x is 5, because then the absolute value of x-5 is 0, and then y is 2.

Therefore, the correct answer will be option B. The y-values are all greater than or equal to 2.

Answer:

you are correct keep up the good work.

Answer:

The 1st one is correct and the second one is (5, -3)

Step-by-step explanation:

For the 1st question this is what I did:

d=√(x^2−x^1)^2+(y^2−y^1)^2

d=(0−4)^2+(6−3)^2

√d=(−4)^2+(3)^2

√d=16+9

√d=25

√d=5

For the second question I did this:

(xM,yM)=(x1+x2/2,y1+y2/2)

M=(xM,yM)

M=(x1+x2/2,y1+y2/2)

M=(3+7/2,−1+−5/2)

M=(10/2,−6/2)

M=(5,−3)

A circle is a curve sketched out by a point moving in a plane. The circumference of the ring of fire is 6.2831 meters.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The circumference of the ring if the radius is 1 meter is,

Circumference of the ring = 2πr = 2 × π × 1 = 6.2831 meters

Hence, the circumference of the ring of fire is 6.2831 meters.

Answer:

13 yards

Step-by-step explanation:

38/3 => 12.6667 yards which would be closest to 13 yards

The formula is to divide the lenght value by 3.

The number 38 feet is equal to 12.67 yards.

We have to give that,

To change 38 feet into yards.

Since we know that,

1 yard = 3 feet

1 feet = 1/3 yards

Hence, change 38 feet into yards as,

1 feet = 1/3 yards

38 feet = 38/3 yards

38 feet = 12.67 yards

The intersection of a plane and a three-dimensional figure results in a triangular cross-section is a triangular pyramid.

A solid's cross-section is a plane figure formed when the solid intersects another plane. As a result, the cross-section of an object is an infinitesimal "slice" of a solid, and it can vary depending on how the slicing plane is oriented. A sphere's cross-section is always a disk, although a cube's cross-section can be square, hexagonal, or another shape.

In these types of three-dimensional geometrical problems imagination of the figures is very crucial.

Now, Think of the plane as a very very thin sheet cutting a triangular pyramid parallel to its base will have exactly the same cross-section as its base and we know a triangular pyramid has a triangular base.

The measure of the angle MOP is 61° (Third option)

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Angle MON is a straight angle → ∠MON=180°

∠QON=58° (according to the graph)

OP bisects angle ∠MOQ, then OP divides angle ∠MOQ into two equal angles:

∠MOP=∠POQ=∠MOQ/2  (1)

∠MOQ+∠QON=∠MON

Replacing the known values in the equation above:

∠MOQ+58°=180°

Solving for ∠MOQ: Subtracting 58° on both sides of the equation

∠MOQ+58°-58°=180°-58°

∠MOQ=122°

Replacing ∠MOQ by 122° in the equation (1)

(1) ∠MOP=∠POQ=122°/2

∠MOP=∠POQ=61°

-10x + 4y = -53

Step-by-step explanation:

-5x+2y = -29

5x - 2y = 24

Answer:

Step 1-Write an equation, letting x represent Kareem’s age:

(x + 3) + x + 2 x = 33

Step 2-Solve the equation:

(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.

Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.

Which corrects the student’s first error?

1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.

2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.

3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.

4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.

230 tickets

Step-by-step explanation:

Create a proportion using the given information:

Let's set x equal to the number of tickets that need to be sold.

[tex]\frac{207}{90} =\frac{x}{100}[/tex]

Cross multiply and you get:

[tex]90x=20700\\[/tex]

Then divide both sides by 90 to get:
