Answer:

y=-4x+1

Step-by-step explanation:

So you can put one point on (1,-3) and another point on (2,-7) and then make a line.

Answer:

Step-by-step explanation:

Let be $y = k\cdot x +1$ the expression of the line, where $x$ and $y$ are the independent and dependent variables, respectively. If we know that $x = 2$ and $y = -7$ , the value of $k$ is:

$-7 = 2\cdot k +1$

$2\cdot k = -8$

$k = -4$

The equation of the line is $y = -4\cdot x +1$ , which is graphed below.

How to express exponential equation, 3^c = 27 , as a logarithmic equation

trasher [3.6K]

If you consider the logarithm base 3 of both sides, you have

$\log_3(3^c) = \log_3(27)$

You can use a rule of logarithms that allow you to turn exponents into multiplicative factors:

$\log_a(b^c) = c\log_a(b)$

So the equation becomes

$c\log_3(3)=\log_3(27)$

Now, by definition, you have

$\log_a(b)=c \iff a^c=b$

So, you have

$\log_3(3)=x \iff 3^x=3 \iff x = 1,\quad \log_3(27)=y \iff 3^y=27\iff y=3$

So, the equation becomes

$1\cdot c = 3 \iff c=3$

inna [77]

Answer:

a) 37th percentile: 33 years

b) 72nd percentile: 62 years

Step-by-step explanation:

The kth percentile divides the data into two: on the one hand the lowest k% of the data, and on the other the (1-k)% higher of the data.

For the list provided, the 37th percentile falls to the age of 33. This means that 37% of the data are for ages under 33 years.

The 72nd percentile falls at the age of 62 (72% of the ages fall below 62 years).

Use the drawing tool(s) to form the correct answer on the provided number line. Consider the given functions. Function 1 Functio

Anna007 [38]

Both functions decrease at (-1, 2)

<h3>How to determine the decreasing intervals of the function?</h3>

The complete question is added as an attachment

The polynomial function f(x) is represented by the graph.

From the graph, the polynomial function decreases at (-2, 2)

The absolute function is given as;

f(x) = =5|x + 1| + 10

The vertex of the above function is

Vertex = (-1, 10)

Because a is negative (a= -5), the vertex is a maximum.

This means that the function decreases at (-1, ∞)

So, we have

(-2, 2) and (-1, ∞)

Combine both intervals

(-1, 2)

This means that both functions decrease at (-1, 2)

See attachment 2 for the number line that represents the interval where both functions are decreasing
