Answer:
-3/5
Step-by-step explanation:
slope is y2 - y1 / x2 - x1
so 1-4/9-4
which equals -3/5
To solve for the value of x, it is easiest by isolating "x" to one side of the equation. This method is shown below:
-2x - 13 = 8x + 7
Adding 2x to both sides:
-2x - 13 + 2x = 8x + 7 + 2x
-13 = 10x +7
Subtracting 7 from both sides:
-13 - 7 = 10x + 7 - 7
10x = -20
Dividing both sides by 10:
10x / 10 = -20 / 10
x = -2

Step-by-step explanation:
Here is the full question :
n a managed forest, three different trees are planted. The trees are beech, holly and maple.
For every beech tree planted, there are 2 holly trees planted and 5 maple trees planted.
(a) Write down the ratio of trees.
b) If 40 maple trees were planted, how many beech trees would be planted?
the ratio of beech to holly to maple = 1 : 2 : 5
number of maple trees planted =( ratio of maple trees / sum of ratios ) x total number of trees
sum of ratios = 1 + 2 + 5 = 8
let a = total number of trees planted
( 5/8 ) x a = 40
a = 64
total number of beech planted = (1 / 8 ) x 64 = 8
