This is true. The word equal in equality will help, each side of the equation in the in(equal)ity should be done the same.
Answer: w = -2
Step-by-step explanation:
7w = -14
Divide both sides by 7
w = -2
That was brief but hope it helps!
Photomath is useful for these kinds of problems
So, we know the slope equation y = mx + b. The b value represents the y intercept, which is the point where the line intersects the y axis. This means that the x value will always be 0. In this equation, the y-intercept is -2, so the y intercept as an ordered pair is : (0, -2). For the x intercept, there are several ways of doing it. For this problem, we can work backwards. There is a slope of 6 units down for every unit right. Starting from our y intercept, we can do the opposite: 6 units up for every unit left. this means our x intercept is -0.3. As an ordered pair, this is (-0.3, 0).
For this case, what you need to know is that to model this problem, you must use equations of the potential type:
y = A * (b) ^ t
Where:
A: initial population.
b: growth rate.
t: time.
Substituting values we have:
y = 15200 * (1.02) ^ t
After 10 years we have:
y = 15200 * (1.02) ^ 10
y = 18529
Answer:
An equation to model of the population growth is:
y = 15,200 ∙ 1.02 ^ x
the population after 10 years is:
about 18,529
