Answer:
-5
Step-by-step explanation:
Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
Answer:
105.12 ft²
Step-by-step explanation:
Let's first find the area of the rectangle.
ft², so the rectangle has an area of 80ft².
To find the area of the semi-circle, we find the area of a whole circle and divide by two.
The formula to find the area of a circle is 
. The radius is 4, as the diameter is 8.
Add 80 and 25.12:
Hope this helped!
Answer:
Correct (1,9), (2,14)
Incorrect (1,8),(2,13)
Step-by-step explanation:
It is simple.
To find the correct values plug a x value.
For Example;
X=1
y=5(1)+4
y=5+4
y=9
so your X value is 1 and your Y value is 9
To solve for the incorrect values
Find the correct values and subtract 1 form the Y value.
-np-4≤2(c-3)
-np-4≤2x-6
-np≤2x-2
-n≤(2x-2)/p
n≥-((2x-2)/p)
