Answer:
∠B = 64.62°
Step-by-step explanation:
cos B = 3/7 = 0.4286
∠B = 64.62°
No, because there is not enough information given to make a conclusion. Providing a percentage of 46% higher profit per acre doesn't mean statistical significance as it could be data-based only. There should be a given p value to make a conclusion about statistical significance.
First find the slope
the slope of the line that passes through (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(-4,3) and (6,-2)
the slope is (-2-3)/(6-(-4))=(-5)/(6+4)=-5/10=-1/2
so
the equation of a line tat passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
use (-4,3)
and we found slope=-1/2
y-3=-1/2(x-(-4))
y-3=-1/2(x+4)
if yo want slope intercept form
y-3=-1/2x-2
y=-1/2x+1
if yo want standard form
1/2x+y=1
x+2y=2
Answer:
x=1
Step-by-step explanation:
1/2x-3/4=3/8-5/8
Combine like terms on the right hand side
1/2x-3/4=-2/8
Simplify the fraction
1/2x-3/4=-1/4
Add 3/4 to each side
1/2x-3/4+3/4 = -1/4+3/4
1/2x = 2/4
Multiply each side by 2
1/2x *2 = 2/4*2
x = 4/4
x=1
