Answer 1

Answer: X=4 Y=-6

Step-by-step explanation:

Well we know that y= -4x+10

So we can input that into the bottom equation

2x +2(-4x+10) = -4

2x +-8x+20=-4

-6x + 20= -4

-6x = -24

x = 4

We also have to find the value of Y

y=-4(4)+10

y= -16 + 10

y=-6

Answer 2

Answer:

Step-by-step explanation:

2x + 2y = -4

Substitute (-4x+10) for y:

2x + 2(-4x+10) = -4

2x -8x + 20 = -4

-6x = -24

x = 4

The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid

Answers

Answer:

84

Step-by-step explanation:

The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid

The area of a trapezoid is given as:

1/2(b1 + b) × h

Where:

b1 = Base 1 = 10

b2= Base 2 = 18

h = Height = 6

Therefore, the area of a trapezoid =

1/2 (10 + 18) × 6

= 28/2 × 6

= 84

Therefore, the area of the trapezoid = 84

Dimitri wrote the equations y = 3x and y = x + 3.
Use the drop-down menus to make true statements about the equations and the graph.

Answers

The coordinate point of intersection on the graph will be at (1.5, 4.5)

Given the equations Dimitri wrote expressd as:

y = 3x

y = x + 3

Since they are both y-values, we can equate the right hand side to have:

3x = x + 3

3x - x = 3

2x = 3

x = 3/2

x = 1.5

Get the value of y:

y = 3x

y = 3(1.5

y = 4.5

Hence the coordinate point of intersection on the graph will be at (1.5, 4.5)

A= _ In2 ?

Answers

Answer:

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

                                              ≈ 225.0 in²

A line is represented by the equation y = 3x - 6. Which is a coordinate of a
point that lies on the line?
0 (0,3)
0 (-6,3)
O (2,0)
0 (-3,1)

Answers

Answer:

(2,0)

Step-by-step explanation:

Simply plug in the coordinates. y= 3x - 6, so in this case 0= 3(2) - 6 or 0=0, making the point on the line. If the equation is not true like when using (0,3) and getting 3= -6, then the point is not on the line.

The set {126, 168, 189} has  21 as a common factor.

The set{154, 231} has  11 as a common factor.

Common factor:

If a number m is completely divisible by number n. Then number n will be the one factor of number m.

(a). Given set of number is, {126, 168, 189}

Now check,  21 is a common factor or not.

 [tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]

It is observed that all numbers are completely divisible by 21.

So that , 21 is common factor.

(b). Given set of number is, {154, 231}

      [tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]

It is observed that all numbers are completely divisible by 11.
