Sum means add
(x+5) + (-4x-2) + (2x-1)
=-3x+3+(2x-1)
=-x+2
+ y = -1 ⇒ y = 
- 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope 
by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + ⇒ y = + 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.
Answer: No Solution

The formula for GP is Tn=ar^n-1
Answer:
The length of the page inside the margins=8 3/4 inches
Step-by-step explanation:
The total length of the year book can be expressed as;
L=l1+l2+l3
where;
L=Total length of yearbook
l1=top margin length
l2=inside margin length
l3=bottom margin length
In our case;
L=10 inches
l1=1/2 inches
l2=unknown
l3=3/4 inches
replacing;
10=(1/2)+l2+(3/4)
(1/2)+(3/4)+l2=10
(5/4)+l2=10
l2=(10)-(5/4)
l2=8 3/4 inches
The length of the page inside the margins=8 3/4 inches
Answer:
24
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices
There are different types of triangles. They include :
- Right angled triangle - one of the angles measure 90 degrees
- equilateral triangle - all three sides of the triangle are equal
- isosceles triangle - two sides of the triangle are equal
Area of a triangle = 1/2 x ( base x height)
1/2 x (6 x 8) = 24 ft²
