Answer: x = -1/2 = -0.5
Step-by-step explanation:
set up an equation
4x + 7 = 5 subtract 7 from both sides
4x = - 2 divide both sides by 4
x = -2/4
x = -1/2 = -0.5
Answer:
19.125
Step-by-step explanation:
multiply 15.5 by 3 and then divide the answer by 4
Answer: M = 2100$
Explanation:
M = P(1 + I)^n
P = 600$, I = 4% = 0.04, n = 10
=> M = 600(1 + 0.04)^10
M = 600(1.04)^10
M = 600(3.5)
M = 2100$
1.) Let's say that the circle on the graph below represents x. The arrow is pointing to all the numbers greater than x, which happens to be on -2. If it points right, this means that x can equal to any number greater than -2. So your answer is x > -2.
2.) For inequalities such as these, you can simplify just like what you do for normal equations. Let's isolate x.
