Answer:

  f(-1) = -1

Step-by-step explanation:

x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...

  f(x) = -2x -3

  f(-1) = -2(-1) -3 = 2 -3

  f(-1) = -1

Answer:

She has 400 megabytes left

Step-by-step explanation:

Answer:

The answer is 630 miles using a 30 gallons tank.

Step-by-step explanation:

Well this question is incomplete, but if we are trying to find how many miles can 30 gallons give then the answer would be 630.

Why? Well since 21 miles = 1 gallon then 630 miles = 30 gallons.

Because 21 multiplied by 30 = 630.

Step-by-step explanation:

y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = 3x - 4 as line L.

Slope of line L = 3

=> Slope of line L2 = -1/3

We have y = -1/3 x + c as our line L2 equation.

When x = 9, y = 5.

=> (5) = -1/3 * (9) + c

=> 5 = c - 3, c = 8

Hence the answer is y = -1/3 x + 8.

The equation of required line [tex]l_2[/tex] is .

Y = mX+c

[tex]Y = \frac{-1}{3} x + 2[/tex]

Given, The equation of straight line L.

Y=3X-4

compareing  with the standard equation of line

Y=mX+c

slope of the equation of line L is [tex]m_1[/tex]= 3.

The product of slopes of two perpendicular lines is -1.

[tex]\rm m_1. m_2 = -1[/tex]

[tex]3.m_2 = -1\\m_2 = \frac{-1}{3}[/tex]

The slope of perpendicular line is  and it passes through the point (9,5). So the equation of the line is

[tex]y = m_2x+c[/tex]

[tex]5 = -\frac{1}{3} . 9 + c[/tex]

5 = -3 + c

5+3 = c

c = 8

Therefore, the equation of required line [tex]l_2[/tex] is .

Y = mX+c

Y = [tex]\frac{-1}{3} X +8[/tex]

Answer: D.) The majority of the data is split to the right and left of the mean

Answer:

A sample size of 1 is never acceptable

Explanation:

A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.

End behavior means what are the y-values doing as the x-values both increase and decrease without bound.

This is a parabola (degree 2) with a negative leading coefficient (−0.25). Therefore both ends of the graph will be going towards negative infinity.

As x increases, f(x) decreases.

As x decreases, f(x) decreases.

Since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that,

f(x) = -0.25x² – 2x + 1

A polynomial function's end behavior defines how the graph acts as x gets closer. The leading term of the function—that is, the term with the highest n-value for a  × n, where n is a positive integer and an is any nonzero number—allows us to infer the function's final behavior.

The highest degree of the given function is 2. When the function is plotted on the graph we get the graph shows downward behavior when x gets closer.

Thus, since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

2x - 5y = 8

x = 8 + 5y .........(1)

5y = -2x + 8

x = 8 - 5y ........(2)

get from 1 and 2

8 + 5y = 8- 5y

Step-by-step explanation:

Given that,

A graph.

To find,

The trans and the reflection.

Solution,

When we slide a figure in any direction, it is called translation or trans.

In this case, option 1 is trans such that ABCD and A'B'C'D' are in same line.

When we flip a figure over a line, it is called reflection.

In this case, option Option 3 is reflection such that ABCD and A'B'C'D' are in opposite direction.

Answer:

46 units.

Step-by-step explanation:

To find the perimeter, you need to add up all the sides. Knowing this, we can set up an equation to solve for y.

2(5y + 1) + 2(4y + 3) = 170

10y + 2 + 8y + 6 = 170

18y + 8 = 170

18y = 162

y = 9

Now that we know y = 9, we can solve for vw.

vw = 5(9) + 1

vw = 45 + 1

vw = 46

Therefore, line vw is 46 units.

Answer: VW=11

4y+3=5y+1
