How many solutions does the equation −4y + 4y + 2 = 2 have?Two
Zero
One
Infinitely many

Answers

Answer 1
Answer: y = 4x – 3y = -3
3x – 4y = 12-4y = 12y = -3
there seems to be a solution
Answer 2
Answer:

Answer:

2 = 2 infinitely many

Step-by-step explanation:

cancel out -4y + 4y because that equals 0 then your left with 2=2 meaning infinitely many solutions i checked it with photo math

A basketball has a diameter of 9.5cm.

Which of the expressions shows how to determine the volume of air the basketball can hold?

A
34π(4.75)3

B
34π(9.5)3

C
43π(4.75)3

D
43π(

Answers

Answer:

C. (4)/(3)\pi\cdot(4.75)^3\ cm^3

Step-by-step explanation:

The volume of the ball with radius R can be calculated using formula

V=(4)/(3)\pi R^3

A basketball has a diameter of 9.5 cm, so its radius is

R=(D)/(2)=(9.5)/(2)=4.75\ cm

Hence, the volume of air the basketball can hold is

V=(4)/(3)\pi\cdot(4.75)^3\ cm^3

Answer:

I also think it's 4/3 ( 4.75 ) 3

If we arrange the equation of a line in standard form,
we can read its slope (gradient) directly.

1).                                            5x + y + 4  =       0

Subtract  4  from each side:    5x + y        =       -4

Subtract  5x  from each side:          y        = -5x - 4

The slope (gradient) of the line is  -5 .    

2).  Parallel lines have the same slope (gradient).
      First, find the slope (gradient) of the given line.

                                          3x + 5y =              15

Subtract  3x  from each side:    5y = -3    x + 15

Divide each side by  5 :              y = -3/5 x + 15

The slope (gradient) of the given line is  -3/5 .
Any line with a slope (gradient) of  -3/5  is parallel to this one.

Its equation will be         y = -3/5 x  +  any number.
