Mathematics

Answer:

They are both linear

Step-by-step explanation:

1.

Use rise/run to find the slope of the line.

rise=21.8

run=1

therefore, the slope is 1/28. You can use that to graph the line. If the line meets the points on your table, it is linear. It does. The equation of the line would be y=21.8x.

2.

We can use the same process as before.

rise=7

run=2

Therefore, slope is 7/2. When this line is graphed it meets all the points, so it is linear.

Alteratively, you could graph the points first and then see if you get the same slope.

What can you say about the y-values of the two functions f(x)=3^(x)-3 g(x)=7x^2-3
Mice21 [21]

Answer: g(x) has the smallest possible y-value of -3

<u>Step-by-step explanation:</u>

f(x) = 3ˣ - 3   <em>This is an exponential graph shifted down three units. So, it has an asymptote at y = -3, which means it approaches -3 but does not touch it.</em>

Range: y > 3   (-3, ∞)

   g(x) = 7x² - 3  

⇒ g(x) = 7(x - 0)² - 3   <em>This is a parabola with vertex at (0, -3) </em>

Range: y ≥ 3   [-3, ∞)

A rectangle has a length of (3.2a + 0.18b)centimeters.The width is half the length. Sasha writes the expression (12.8a + 0.72b)
jeka94
The width is half the length, so is
  width = (1/2)*length
  width = (1/2)*(<span>3.2a + 0.18b) cm
  width = (1.6a +0.09b) cm

The perimeter of the rectangle is twice the sum of length and width.
  perimeter = 2*(length + width)
  perimeter = 2*((3.2a +0.18b) cm + (1.6a +0.09b) cm)
  perimeter = 2*(4.8a +0.27b) cm)
  perimeter = (9.6a +0.54b) cm

Sasha did not get this answer, so apparently ...
  her reasoning was not correct.</span>

Find the product. Write your answer in exponential form. 6^-6x6^-1
Tom [10]
So, the questions is 6^(-6) * 6^(-1).

Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.

In this ,case it is, -6 and -1.

-6 + (-1) = -7

So the answer would be 6^(-7).
