Step-by-step explanation:
the last one
x^2+2x+1 R(-5)
Answer:
area = (1/2)|Ax(By-Cy) +Bx(Cy-Ay) +Cx(Ay-By)|
= (1/2)|2(3-6) +3(6-1) +1(1-3)| = (1/2)|-6 +15 -2|
area = 7/2

Answer:
D. The sum is a rational expression.
Step-by-step explanation:
the given expression is a/b +c/d
so in the question it is given that b and d are non zero values
a/b is rational number and c/d is a rational number
so if both are rational number , so we know that the sum of rational number is also a rational number.
The right option is D. The sum is a rational expression
Answer: The Answer is <u>A: 7.685</u> but then round it up to <u>8</u> on edge
Answer:
x = 4
y = -3
Step-by-step explanation:
We can use substitution, elimination, or graphically.
Step 1: Rearrange first equation
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Step 2: Rewrite systems of equations
x = -2 - 2y
3x + 5y = -3
Step 3: Substitution
3(-2 - 2y) + 5y = -3
-6 - 6y + 5y = -3
-6 - y = -3
-y = 3
y = -3
Step 4: Find <em>x</em> using <em>y</em>
2x + 4(-3) = -4
2x - 12 = -4
2x = 8
x = 4
Graphically:
Use a graphing calc and analyze where the 2 lines intersect.
