Answer:
2/3
Step-by-step explanation:
Look at what you are getting on the right hand question. 10a +10b has a common factor that can be pulled out. It is 10
10a + 10b = 10(a + b)
Now look at the denominator
9x - 9y = 9(x -y)
There are a lot of possible answers.
Mine would be to multiply 3/5 * 10/9
so
(10a + 10b)/(9x - 9y) = 2/3
Answer:
exponential function going through point 0, negative 2 and ending down on the right
Step-by-step explanation:
y = -2(3^x)
At x = 0, -2(3⁰) = -2
At x = 1, -2(3¹) = -6
Down, when towards right
Hello :
<span>x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2πis solutions of : f'(x) =0
f'(x) = - 2sin</span><span>(2x − π)
</span>- 2sin(2x − π) =0
sin (2x − π) =0
2x − π = kπ ... k in Z
x=(k+1)π/2....(general solutions in R)
<span>from x = 0 to x = 2π :
</span>k =0 : x = π/2
k=1 : x= π
k=2 : x= 3π/2
k = 3 : x=2π
Remains to be determined whether it is a maximum or minumum
Considering the linear function described, 500 liters of fuel were initially in the tank.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Researching this problem on the internet and looking at the graph, we have that when x = 0, y = 500, that is, the y-intercept is of 500. From the bullet points, the y-intercept is the initial value, hence 500 liters of fuel were initially in the tank.
