Answer:
Step-by-step explanation:
these seem complicated, but just think about what they are asking. they are giving you a point and a slope to a line.
That gives you the hint to use the "point-slope" formula
if you don't have it memorized you might as well start trying to now. You'll need this over and over and over...
y-y1=m(x-x1)
so plug in the given info
y-4= (-1/4)(x-(-2))
y-4 = -1/4 (x +2)
y-4 = (-1/4)x -1/2
y = (-1/4)x + 7/2 this is the slope intercept formula. y = mx +b
we can now graph this line with the slope intercept formula.
note the graph does pass through (-2,4) and has a -1/4 slope :)
no the square root of 113 is rounded to 56x2
Answer:
4th option
Step-by-step explanation:
7x(8x² - 4y² + 3y - 5) ← multiply each term in the parenthesis by 7x
= 56x³ - 28xy² + 21xy - 35x
Answer:
The perimeter of rectangle is 
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
----> equation A
---> equation B (area of the constructed figure)
substitute the equation A in equation B
using a graphing tool -----> solve the quadratic equation
see the attached figure
The solution is
Find the value of x
----> 
Find the perimeter of rectangle
Answer:
The volume of a cone is 1 3 π r 2 h \frac { 1 } { 3 } \pi r ^{ 2 } h 31πr2h, where r denotes the radius of the base of the cone, and h denotes the height of the cone.
