Big bend national park has about 870 oak trees. Brazos bend state park has about 565 oak trees. About how many more oak trees does big bend national park have than Brazos bend state park
I do not know how to post the picture but the answers are
A. Y= -1/3x - 1
B. Y=-3x -1
C. Y=3x + 1
D. Y=3x - 1
slope = (y2-y1)/((x2-x1)
= (-4-2)/(1-(-1))
= (-6/2)
m = -3
point slope form
y-y1 = m(x-x1)
y-2 = -3(x-(-1))
y-2 =-3(x+1)
y-2 = -3x-3
y= -3x-3+2
y=-3x-1
Choice B
Answer:
12
Step-by-step explanation:
My suggestion for this problem is to break the shapes up like outlined on the problem so you have a square and two triangles.
First Triangle: 2
The legs of the triangle are 2 so you plug it in for the formula for a triangle's area: A=1/2bh
A=1/2(2)(2)= 2
Square: 4
multiple length times width so you get 2*2 = 4
Last Triangle: 6
A=1/2(2)(6)=6
At the end you add up your areas and you get 2+4+6=12
Find slope-
x-intercept-
y-intercept-
get the equation in slope intercept form
2x-3y=9
subtract 2x from each side
-3y = -2x +9
divide by -3
y = 2/3 x -3
slope = 2/3
y intercept = -3
x intercept set y=0 and solve
0 = 2/3 x -3
add 3 to each side
3 = 2/3 x
multiply each side by 3/2
9/2 = x
the x intercept is 9/2 or 4 1/2
