we are given
Volume of water in lake in mi^3
now, we know that
we can multiply both sides by 2900
we can write in scientific form
...........Answer
Answer:
For the first one:
y = 2/3x + 1
For the second one:
y = -5x + 4
Step-by-step explanation:
As you may already know, in the y=mx+b equation format:
m = slope
b = y-intercept
On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.
And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.
Then, you can just leave the variables y and x alone.

Answer:
x1= -7
x2=7
Step-by-step explanation:
To find the zeros of a polynomial function, you need to factorize it into multiple monomials or simply use a formula. Most questions want you to factorize the function, so I will solve this by factorization
g(x)=-10x^2 +490
0= -10x^2 +490 ----> we looking for zeroes, so g(x)=0
-10(x^2 - 49)=0 ---> divide -10 from both number
x^2 - 49 =0 ---> divide both side by -10, notice that 49 is 7^2
(x+7)(x-7)=0 ---> x^2 - y^2 = (x+y) (x-y)
x1
x+7 = 0
x= -7
x2
x-7=0
x= 7
