Answer: B) A=1/2(7)(12).
Explanation: The formula for area of a triangle is 1/2bh. Only B maintains this formula.
Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
Step-by-step explanation:

Answer:
Prime. Prime numbers can only be divided by the whole number, or one.
Horizontal line is y=a, where a is a constant (number).
We need to choose equation this type.
y= - 7, means that for all values of x y=7.
So, answer is
B. y= - 7
