7x-(x-y) = 7x - x + y = 6x + y

9a-(2b-a) = 9a+a-2b = 10a-2b

hope it helped

Since there's a - next to the bracket, you minus everything inside of it, if there's a minus in the bracket, it turns to +
7x-(x-y) = 7x-x+y = 6x+y
9a-(2b-a) = 9a-2b+a = 10a-2b

Slope -1/4, passes through (12,-4)​
Kazeer [188]

Answer:

y = - \frac{1}{4} x - 1

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - \frac{1}{4} , then

y = - \frac{1}{4} x + c ← is the partial equation

To find c substitute (12, - 4) into the partial equation

- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1

y = - \frac{1}{4} x - 1 ← equation of line

36 creates of apples. each creat has 25 kgs of apples. they sell 486,235 games of apples. how many grams are left?
valentinak56 [21]

The grams of apples left is 413765 grams

<h3>How to determine the value</h3>

From the information given, we have that:

  • There are 36 crates of apples
  • Each contains 25 kilograms of apples
  • 486,235 grams of apples were sold

If we have 36 crates, let's determine the the total grams of apples

1 crate = 25 kilograms = 25000 grams

36 crates = x

x = 25000 × 36

x = 900000 grams

The total grams of apple is  900000 grams

The grams left = Total - sold =  900000 - 486,235 = 413765 grams

Thus, the grams of apples left is 413765 grams
