137 - 16X = Y

Since Lorraine is picking blackberries in her backyard at a rate of 15 berries per minute, and after 16 minutes of picking, there are still 137 blackberries left to pick, to determine an equation that models how many berries are left (y) after x minutes of picking, the following calculation must be performed:

137 - 16X = Y

Thus, for example, after 5 minutes the calculation would be as follows:

  • 137 - 16 x 5 = Y
  • 137 - 80 = Y
  • 57 = Y

2) Which two statements are not true?
GalinKa [24]

Answer:

A repeating decimal is not a rational number and The product of two irrational numbers is always rational

Step-by-step explanation:

One statement that is not true is "The product of two irrational numbers is always rational". Take for example the irrational numbers √2 and √3. Their product is √6 which is also irrational.

The other false statement is "A repeating decimal is not a rational number". Take for example the repeating decimal 0.33333..... It can be written as 1/3 which is a rational number.

y = x2 − 6x + 8 2y + x = 4 The pair of points representing the solution set of this system of equations is
algol [13]
2y + x = 4
x = -2y + 4

y = x^2 - 6x + 8
y = (-2y + 4)^2 - 6(-2y + 4) + 8
y = (-2y + 4)(-2y + 4) + 12y - 24 + 8
y = 4y^2 - 8y - 8y + 16 + 12y - 24 + 8
y = 4y^2 - 4y 
4y^2 - 4y - y = 0
4y^2 - 5y = 0
y(4y - 5) = 0
 
y = 0                x = -2y + 4
                        x = -2(0) + 4
                        x = 4

4y - 5 = 0          x = -2y + 4
4y = 5               x = -2(5/4) + 4
y = 5/4              x = -10/4 + 4
                         x = -10/4 + 16/4
                         x = 6/4 which reduces to 3/2

so u have 2 sets of points that will work....
