Solve the equation for y. Type out your steps to solve this problem as you are showing your work:

4y – 4 = 2y + 8

Answers

y = 6

4y - 4 = 2y + 8
subtract 2y from both sides
2y - 4 = 8
add 4 to both sides
2y = 12
divide both sides by 2
y = 6

Chord AC intersects chord BD at point P in circle Z. AP=12 m DP=5 m PC=6 m What is BP?

Answers

Answer:

BP = 14.4

Step-by-step explanation:

Given 2 chords intersecting inside a circle, then

The products of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

BP × DP = AP × PC , that is

BP × 5 = 12 × 6

5BP = 72 ( divide both sides by 5 )

BP = 14.4

Great freight a local shipping company charges .40 per pound for shipping if your shipping 20 pounds what would the cost be

Answers

Answer:

$8.00

Step-by-step explanation:

For every pound shipped, $0.40 is charged. This can be represented by the mathematical equation: y=0.4x, where x is the pounds to ship and y is the total cost. If we plug in 20 as x to find what the total cost would be, we would have the equation, y=0.4*20, and y would equal 8, meaning that the total cost is $8.00.

The side of a box has length x feet, and another side has length (x-7) feet. What value of a would produce an area of 18 square feet?

Answers

Answer:

x=9

Step-by-step explanation:

(9-7) = 2

9 times 2 = 18 square feet

Value of x is 9 , -2

Given that;

Length of box = x feet

Width of box = (x - 7) feet

Area of box = 18 square feet

Find:

Value of x

Computation:

Area of rectangle = Length × Width

Area of rectangular box = x × (x - 7)

x² - 7x = 18

x² - 7x - 18 = 0

Using factorisation;

x² - 7x - 18 = 0

x² - (9 - 2)x - 18 = 0

x² - 9x + 2x - 18 = 0

x(x - 9) + 2(x - 9) = 0

(x - 9)(x + 2) = 0

So,

x = 9,  x = -2

The solution to a system of linear equations is (0,4) one of linear equations in the system is y=8x+4

Answers

Answer:

(-1/2, 4)

Step-by-step explanation:

Get the x intercept. The x intercept occurs at when y = 0

0 = 8x + 4

-8x = 4

x = 4/-8

x = -1/2

Get the y intercept

y intercept occurs at x = 0

y = 8(0) + 4

y = 0+4

y = 4

Hence the required solution is (-1/2, 4)

Thomas decides on a destination for his vacation. If he takes the train there, it will take 5 1/8 hours to get there. If he takes the plane, it will take him 2 2/3 hours

Answers

Answer: 2 11/24

Step-by-step explanation:

How many hours does the plane save?

Time taken for the train = 5 1/8

Time taken for the plane = 2 2/3

The number of hours saved will then be:

= 5 1/8 - 2 2/3

Let the lowest common multiple be 24

= 5 3/24 - 2 16/24

= 2 11/24

The number of hours saved by the plane will be 2 11/24
