Answer:
y=8x-23
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is 8, m=8.
subst. m=8 into the equation:
y= 8x +c
To find c, substitute a coordinate.
When x=3, y= 1,
1= 8(3) +c
1= 24 +c
c= 1 -24
c= -23
Thus, the equation of the line is y= 8x -23.
Answer:
x=28
Step-by-step explanation:
So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle
180-40=140
140/5=28
2(28)=56
56 is angle A
Total area = 4 × 8.5 × 11 = 374 in²
374 in² = 374/144 = 2.597 ft²
