21x-9+6y
combining terms: 4x+17x=21x
Answer:
Start at (0, 0), or the origin. Just go to (0, 0), which is the intersection of the x and y axes, right in the center of the coordinate plane. 2. Move over x units to the right or left. Let's say you're working with the set of coordinates (5, -4). Your x coordinate is 5.
Step-by-step explanation:
Answer:
40 trees
Step-by-step explanation:
Let the total number of trees be x.
75% of all the sycamore trees in the park are 30 trees.
So,75%of x=30
or,(75/100)*x=30
or,x=(30*100)/75
or,x=40 [ANS]
Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7
