What is the equation of a line in slope intercept form that is parallel to y-4=2(x+3) that goes through (-1,2)

Since the equation we're looking for is parallel to another line, we can "steal" the second line's slope and use it in our equation.

Point-slope formula:
y - y1 = m(x - x1)
y - 2 = 2(x-(-1))
y - 2 = 2(x+1)

Solve for y to put into slope intercept form:
y - 2 = 2x + 2
y = 2x + 4

Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number
liberstina [14]

Answer:

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

Step-by-step explanation:

From the first equation:

20x - 80y = 100

20x = 100 + 80y

x = \frac{100 + 80y}{20}

x = 5 + 4y

Replacing on the second equation:

-14x + 56y = -70

-14(5 + 4y) + 56y = -70

-70 - 56y + 56y = -70

0 = 0

This means that the system has an infinite number of solutions, considering:

x = 5 + 4y

4y = x - 5

y = \frac{x - 5}{4}

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

The large rectangle below represents one whole.
dolphi86 [110]

Answer: 44%

Step-by-step explanation:

There are 25 squares in the rectangle. This means that the percentage of each square is:

= 1/25 * 100

= 4%

There are 11 shaded squares so the percentage represented is:

= 11 * 4%

= 44%
