Answer:

To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Parent Function: y = 6 x ^2

Horizontal Shift: Left 1 Units

Vertical Shift: None

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: None

Find the solution of the system of equations. – 2 – 8y = -30 2x + 8y = 36

nydimaria [60]

Answer:

x= 1.5

y= 4.125

Step-by-step explanation:

Step one:

given the two equations

$-2x - 8y = -30-------1\\\\2x + 8y = 36--------2$

Step two:

let us subtract the equations

$-2x - 8y = -30-------1\\\\ -(2x + 8y = 36)--------2\\\\0x-16y=-66$

$-16y=-66\\\\16y=66$

divide both sides by 16

$y=66/16\\\\y=4.125$

put y= 4.125 in equation 2

$2x + 8(4.125)= 36\\\\2x+33=36\\\\2x=36-33\\\\2x=3\\\\x= 3/2\\\\x= 1.5$

Slove for y show all your work 12y + 4 = 8y-12

Vedmedyk [2.9K]

Answer:

y = -4

Step-by-step explanation:

12y + 4 = 8y-12

Subtract 8y from each side

12y - 8y +4 = -12

4y +4 = -12

Subtract 4 from each side

4y +4-4 = -12 -4

4y = -16

Divide by 4

4y/4 = -16/4

y = -4

4a-b Evaluate the expression when a=5 and b=-7

stepladder [879]

Answer:

Step-by-step explanation:

So first we need to plug in 5 as the variable a and -7 as the variable b

4(5)-(-7)

Next we multiply the 4 and the 5 together to get 20

4(5) = 20 or 4 x 5 = 20

20-(-7)

Now we subtract negative 7 from 20

20-(-7) = 27

This can also be written as 20 plus 7 as a mathematical rule states: two negatives make a positive. So:

20-(-7) = 20 + 7

Both of these are equivalent in every sense of the word and give us our final answer of 27

The inside ring of packing tape has a diameter of 80 mm. The tape surrounding the ring is 8 mm beyond the ring. What is the dist

Nutka1998 [239]

Answer:

301.44 mm

Step-by-step explanation:

Diameter of the inside ring of a packing tape = 80 mm

The tape surrounding the ring is 8 mm beyond the ring which means the diameter of the ring including the surrounding will be:

80 + 8 + 8 = 96 mm

and its radius will be = 96/2 = 48.

To find the distance around the outer edge of the tape, we need to calculate the circumference for the ring with the tape on it.

Circumference = $2\pi r$ 

Circumference = 2 x 3.14 x 48 = 301.44 mm

Therefore, the distance around the outer edge of the tape is 301.44 mm.
