Answer: Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted


Step-by-step explanation:

Given: Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality

7.2b + 6.5 > 4.8b – 8.1.

If Luis started by subtracting 4.8b from both sides ,then he would get

7.2b + 6.5 - 4.8b> 4.8b – 8.1- 4.8b

⇒2.4b + 6.5 > – 8.1.  But he wrote 2.4b + 6.5 < – 8.1 by flipping the inequality sign which was not correct .

The sign of inequality get flipped if we multiply or divide a negative numbers to the both sides .

Therefore, Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted.

Solve for x. pls pls pls pls pls pls
Lynna [10]

Answer:

smaller \: x =  \boxed  { - 5} \\ larger \: x =  \boxed 2

Step-by-step explanation:

5 {x}^{2}  + 15x - 50 = 0 \\ 5( {x}^{2}  + 3x - 10) = 0 \\ {x}^{2}  + 3x - 10 = 0  \\  {x}^{2}  + 5x - 2x - 10 = 0 \\ x(x + 5) - 2(x + 5) = 0 \\ (x + 5)(x - 2) = 0 \\ x + 5 = 0 \: or \: x - 2 = 0 \\ x =  - 5 \:or \: x = 2 \\ smaller \: x =  \boxed  { - 5} \\ larger \: x =  \boxed 2

Q8: Identify the graph of the equation. What is the angle of rotation for the equation?
Allisa [31]

Answer:

B. hyperbola, 45°

Step-by-step explanation:

This is rotation in quadratic equations

Perform elimination of xy term

Ax² +B xy+Cy²+Dx+Ey+F=0

Rotation of axes of the coordinates through angle θ to satisfy

Cot 2θ =(A-C)/B

But B≠ 0 and A=C=0

Answer will be hyperbola, 45°

<h3>What is called a triangle?</h3>
  • A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
  • Triangles are three-sided shapes. The various kinds of triangles go by various names. The angles' size and the sides' length determine the type of triangle (corners). Equilateral, isosceles, and scalene triangles are the three varieties of triangles based on the length of the sides.
  • The triangle is most frequently seen in our daily lives on traffic signs. The signs are triangular in shape and equilateral, which means that all three of their sides are the same length and have the same angle.

At what point should the statue be:

The intersection of the doors to the arena, the spirit store, and the parking lot forms a triangle, with Point E in its center. The radius of the circumscribed circle will therefore equal the distance from the statue to each vertex, placing it at the same distance from all three landmarks.

Point E is where the statue should be placed.
