Answer:
x intercept:
5
y intercept: 50
Step-by-step explanation:
- let us plot the graph for better understanding.
- we will represent f(x) on y-axis so, the equation will become: y= 50-10x
- the equation is of the form : y=mx+c
[where, m: slope of the line
c : y-intercept ]
- meaning of x intercept: the x-coordinate of the point where the line meets x-axis
-
meaning of y intercept: the y-coordinate of the point where the line meets y-axis
- the line y= 50-10x has slope of -10 and it passes through (0,50)
[ (0,50) lies on the line only. substitute and check if the point satisfies the above line equation]
- by seeing the graph in the attachment and by the definitions given above, we can say that,
x intercept: 5
y intercept: 50
It would be: 305*23 / 100
= 305 * 0.23
= 70.15
So, your final answer is 70.15
Answer:
SA =64 pi units ^2
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
SA = 4 * pi * 4^2
SA =64 pi
SA =200.96
Answer:
-x -9y
Step-by-step explanation:
-(3x+y)+2(x-4y)
-3x -y +2x -2*4y
-x -y -8y
-x -9y
We have that
−27x2yz5 + 15x3z3
we know that
27-------------> 3³
15-------------> 3*5
z^5-----------> z² * z³
x³------------> x² * x
substituting in the original expression<span>
−27x2yz5 + 15x3z3---------->[-3</span>³*x²*y*z³*z²]+[3*5*x²*x*z³]
[-3³*x²*y*z³*z²]+[3*5*x²*x*z³]-------> [3*x² *z³]*{[-3² *y*z²]+[5*x]}
the greatest common factor is [3*x² *z³]
