Answer:
D
Step-by-step explanation:
We can substitute y = 2x + 1 in the second equation
2x + 1 = -7x + 8
Add 7x to both sides
9x + 1 = 8
Subtact 1 from both sides
9x = 7
x = 7/9
Substituing x in the first equation
y = 14/9 + 1
x rounds to 0.8
y rounds to 2.5
Answer:
Solving for the value of x in the inequality will give us an answer of x > 7. Thus, the side of the congruent side of the triangle should be greater than 7 feet.
Answer:
value was â€"4. Which could be Arianna’s original expression? One-sixth (negative 3 x minus 24) One-sixth (negative 5 x minus 8) One-sixth (negative 10 x minus 4) One-sixth (negative 12 x minus 16).
So remember that area of a rectangle is a = bh. In this case, our sides are 2 and n - 3 (three less than unknown number) and our area is 22. Using our info, we can form the equation: 
. From here we can solve for n.
Firstly, foil 2(n-3): 
Next, add 6 on both sides of the equation: 
Next, divide both sides of the equation and your answer will be 14 = n. In context, the value of the unknown number is 14 in.
