Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-1,0)
Equation form: x=-1,y=0
Answer:
y=2
x=3
Step-by-step explanation:
We need to solve for the y-intercept of the line and the given values are enumerated below:
point slope = m = 4.404
mean of the x coordinate of the data point = 8.891
mean of the y coordinate of the data point = 5.519
We can use the equation of the line in a point-slope form such as:
y = mx + c
Let us solve first the value of c:
5.519 = (4.404* 8.891) +c
c = 5.519 - (39.156)
c = -33.637
the y-intercept is when x is equal to zero, we have:
y = 4.404(0) + (-33.637)
y= -33.637
The answer is -33.637 for y-intercept.
Answer:

21 will be the second piece
Answer:
273.2
Step-by-step explanation:
Surface area of the pyramid=Area of square+4*area of triangle
Surface area of the pyramid=10^2+2*(8.66)*10
Surface area of the pyramid=100+173.2=273.2
