1. Consider f(x) = 3x - 5

Mathematics
1 answer:
Rzqust [24]3 years ago
4 0

Answer:

3

Step-by-step explanation:

Here we have the function

f(x)=3x-5

We want to find the following ratio:

\frac{f(x+h)-f(x)}{h}

Note that the limit of this for h\rightarrow 0 is equivalent to the derivative of the function.

Here we have:

f(x+h)=3(x+h)-5=3x+3h-5

And

f(x)=3x-5

Therefore we have

f(x+h)-f(x)=3x+3h-5-(3x-5)=3h

And therefore,

\frac{f(x+h)-f(x)}{h}=\frac{3h}{h}=3

The zeros of the function are , 3, and , and the y-intercept of the function is located at .
MissTica

Answer:

The zeroes are -1, 3, and -2

The y intercept is located at (0,6)

Step-by-step explanation:

(x+2)=0

x=-2

The easiest way is to use an online graph like desmos and graph the problem there. You can see where the y intercept is.

Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5.20.
Step2247 [10]

Answer

B is the correct answer.

Step-by-step explanation:

This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?

x = dimes          x = 0.10 or 0.1

y = quarters      y = 0.25

31 coins

worth $5.20       = 5.2

x + y = 31

0.1x + 0.25y = 5.2

The total number of degrees, D, in an n-sided polygon is given by the formula D=180(n-2). When Janelle solves for n, she gets n=
Rus_ich [418]
<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2

So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct
