Find the area of the composite shape
8090 [49]

Step-by-step explanation:

Radius = 4 ft

Side of the square = 8 ft

Area of circle = πr² ≈ 3 × 4² = 48 ft²

Square area = a² = 8² = 64 ft²

area of composite shape = Square area - Area if circle = 64 - 48 = 16 ft²

A line is drawn on a coordinate grid by the equation x = 6. Which of the following lines would represent a row parallel to it?
elena-14-01-66 [18.8K]

Answer:

D, x = 3

Step-by-step explanation:

to know if a line is parallel, we need to know what kind of line x = 6 is

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:

Vertical line

Undefined slope

X axis

Horizontal line

0 is the slope

Y axis

according to this, the equation x = 6 is a vertical line

now we can start eliminating answer choices

A. a line containing the point (6,2)

the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this  is not parallel to the line

B. y = 6

this intersects x = 6 and is not parallel

C. y = 4

this intersects x = 6 as well and is not parallel

D. x = 3

this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

Solve the inequality.
nataly862011 [7]

Answer:

D

Step-by-step explanation:

4x + 3 < 3x + 6 ( subtract 3x from both sides )

x + 3 < 6 ( subtract 3 from both sides )

x < 3 → D

Help please!!!!!!!!!!!!!
Bingel [31]
Combine the 2nd and 3rd equations.  3x will disappear:

 2y + 5z = 7  This is true for any y and z, and is independent of x.
 
                                                            7-5z
Solving for y, 2y = 7 - 5z, so that y = ---------
                                                               2

We have to eliminate x again by using the 1st and 2nd equations:

 -2x - 6y - 2z = -2.  We want the coeff. of x in the first eqn to be -3.  

Therefore, mult. all terms of  -2x - 6y - 2z = -2  by 3/2:

(3/2)(-2x - 6y - 2z = -2) = -3x -9y  -3z =-3

Now add this version of the 1st row to the 2nd row:

  -3x -9y  -3z =-3
   3x +2y +5z = 7
----------------------
         -7y + 2z = 4
                                          7 - 5z
We found earlier that y = ----------, and can elim. y by subst. this fraction into 
                                              2

 -7y + 2z = 4.  Then     -7y + 2z = 4 becomes   -7( (7-5z)/2 ) + 2Z = 4.

Elim. the fraction by mult. all terms by 2:

-7(7-5z) + 4z = 8    which becomes    -49 + 35z + 4z = 8

so that 39z = 57, and so z = 57/39.

Subst. this back into -7y + 2z = 4 to calculate y.  Make a final subst. to calculate x.

Given the choice, I would solve this system using matrices.

Turns out that the solution, using matrices, does not exist.
