No

(The first system is correct but the second one is wrong)

Step-by-step explanation:

You can plug (-10,10) into these equations

a)  18(-10)+20(10)=20

      -180+200=20

            20=20

b) 20(-10)-2(10)=9

      -200-20≠9

         -220≠9

A centroid is the intersection point of the medians of a triangle. The required length of DG is 2.4 unit.

A triangle is a two dimensional shape bounded by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.

Given that,

There is a triangle ΔDEF.

The centroid of the given triangle is G.

The medians of the triangle are DC, EB and FA.

CG = (x + 5)

DG = (3x - 2)

Here, CG and DG are parts of the median DC.

Since, centroid of a triangle divides its each medians into the ratio of 2 : 1

in the direction from the vertex to the midpoint of the opposite side.

The following expression can be written for the given problem,

DG/CG = 1/2

=> (3x - 2)/ (x + 5) = 1/2

=> 2(3x - 2) = x + 5

=> 6x - x = 5 + 4

=> x = 9/5

=> x = 1.8

Thus, DG = (3x - 2)

                = 3 × 1.8 - 2

                = 2.4

Hence, the length of DG is given as 2.4 unit.

Answer:

Step-by-step explanation:

Quadratic function is a function that can be described by an equation of the form fx = ax2 + bx + c, where a ≠ 0.

Example:

1. Use the graph of y = x2 + x - 6 to solve x2 + x - 6 = 0.

2. Use the graph of y = -x2 + 4 to solve -x2 + 4 = 0.

3. Use the graph of y = x2 -2x + 1 to solve x2 -2x + 1.

Step-by-step explanation:

Dominique - 12

Brother- 12 / 6 * 4

12 / 6 is 2 then 2 * 4 is 8.

So her brother is 8 years old.

To prove this multiply 8 by 2 givig you 16. then 16 - 4 giving you 12. This means the answer is correct because dominique is supposed to be 4 years less than TWICE THE AGE OF HER BROTHER.

Answer:

9 feet away

Step-by-step explanation:

40²+b²=41²

1600+b²=1681

b²=81

b=9

The base of the flagpole from the end of the rope is 9 feet.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Hypotenuse = 41 foot

Base = x

Height = 40 foot

Applying the Pythagorean theorem.

41² = x² + 40²

1681 = x² + 1600

x² = 1681 - 1600

x² = 81

x = 9

Thus,

The base of the flagpole from the end of the rope is 9 feet.
