Answer:
x = 1
, y = 3 thus: A is your Anser
Step-by-step explanation:
Solve the following system:
{2 x + y = 5 | (equation 1)
x + y = 4 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + y = 5 | (equation 1)
0 x+y/2 = 3/2 | (equation 2)
Multiply equation 2 by 2:
{2 x + y = 5 | (equation 1)
0 x+y = 3 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 2 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 1 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 1
, y = 3
Answer:
<h2>17.2cm^2</h2>
Step-by-step explanation:
step one:
The question did not give the area of the pan and the number of biscuit
so let assume an are of 80cm^2 of the pan and the number of biscuit is 20
the diameter of each biscuit is 2cm
the radius is 2cm
The expression for the area is
A=πr^2
A=3.14*1^2
A= 3.14cm^2
the total area covered by the biscuit is
=3.14*20
=62.8cm^2
the area not covered is
=80-62.8
=17.2cm^2
It says my answer needs to be at least 20 characters long but here 60, 4, -70, -76, -12

Step-by-step explanation:
Answer : <em>Equation of line is</em> y=Equation of line is y=x+
Step-by-step explanation:
Theory :
Equation of line is given as y = mx + c.
Where, m is slope and c is y intercepted.
Slope of given line : y = x+1 is m=
We know that line : y = x+1 is parallel to equation of target line.
therefore, slope of target line will be .
we write equation of target line as y= x+c
Now, It is given that target line passes through point ( -5,-2)
hence, point ( -5,-2) satisfy the target line's equation.
we get,
y= x+c
-2= -5+ c
-5= +c
c=
thus, Equation of line is y=Equation of line is y=x+
