Answer:
Graph the equations
Step-by-step explanation:
x - y = 1
3x + 2y = - 12
Rewrite equations into y=mx+b form:
y = -1 + x
y = -6 - 1.5x
Graph it!
Answer:
Step-by-step explanation:
2(L+B)
Where L is the length and B is the breadth.
Figure 2 & 4
Figure 2 is scaled 2x the size of the letter A
Figure 4 is 2x smaller than the size of the letter A
5b + r = 30
the cost per item * the number of items sold = the profit
Area = PI x r^2
Circumference = 2 x r x PI
Using area find the radius )r)
616 = 22/7 x r^2
Divide both sides by 22/7:
196 = r^2
Take the square root of both sides:
r = 14 cm
Now find the circumference:
2 x 14 x 22/7 = 88 cm
Answer : A) 88 cm
