Answer:
x=3, y= -2
Step-by-step explanation:
Multiplying :
(4x+3y =6)*-3
(3x+5y =-1)*4
-12x -9y= -18
12x+20y= -4
Add the equations
20y-9y = -4-18
11y = -22
y= -22/11 = -2
3x +5* -2= -1
3x -10 = -1
3x = 10-1
x= 9/3 =3
Answer:
Since
and
, then the quadrilateral ABCD is a parallelogram.
Step-by-step explanation:
First, we label each point of the quadrilateral with the help of a graphing tool. If the quadrilateral ABCD is a parallelogram, then
and
. If we know that
,
,
and
, then the measure of each vector is, respectively:








Since
and
, then the quadrilateral ABCD is a parallelogram.
Subtract 60-5 which would be 55, then divide 55 by 1.25 which would be 44 rides

Answer from Gauthmath
Answer:
the area of the cover will be

Step-by-step explanation:
This problem bothers on the mensuration of flat shapes. oval/ellipse
the area of the ellipse is
.
Since we are multiplying two units of length together, our answer will be in units squared.
also the oval/ ellipse has to radius major and minor radius
Given data
minor radius = a= 10 feet
major radius= b= 26 feet
furthermore we want the cover to extend 1 feet
hence
minor radius = a= 11 feet
major radius= b= 27 feet
