Explain or show your reasoning.
(-3,-4) (6, _)

Given - F(x) = 5 × 3-x

F(-2) refers to x = -2

Therefore 5×3-(-2) = 5× (3+2) = 5×5 = 25

Hence 25 is the value of f(-2)

Answer:

  y = -3

Step-by-step explanation:

You want the solution to the absolute value equation | y-4 | = | y+10 |.

The absolute value function ...

  f(x) = | x |

is piece-wise defined as ...

  [tex]f(x)=\begin{cases}-x&\text{for }x < 0\\x&\text{for }x\ge 0\end{cases}[/tex]

That is, the function is defined differently for argument values less than 0.

The above observation regarding the absolute value function means the nature of the given equation changes where the absolute value arguments are zero. Those values are ...

  y -4 = 0   ⇒   y = 4

  y +10 = 0   ⇒   y = -10

In other words, the points y = -10 and y = 4 divide the domain of the equation into three parts. The behavior will be different in each of those parts.

To solve the equation, we must examine each region of the domain for possible solutions.

When y < -10, both of the absolute value functions change the sign of their argument. Then the equation is ...

  -(y -4) = -(y +10)

Adding y to both sides of this equation gives ...

  4 = -10 . . . . . false

This means there is no solution to the equation in the region y < -10.

When -10 ≤ y < 4, the absolute value function |y -4| changes the sign of its argument, but the other function does not. In this region, the equation becomes ...

  -(y -4) = (y +10)

  -6 = 2y . . . . . . . . . add y-10 to both sides

  -3 = y . . . . . . . . divide by 2. This value is in the region -10 ≤ y < 4.

The solution to the equation is y = -3.

When 4 ≤ y, neither absolute value function changes the sign of its argument. In this region the equation becomes ...

  y -4 = y +10

Subtracting y from both sides of this equation gives ...

  -4 = 10 . . . . . false

This means there is no solution to the equation in the region 4 ≤ y.

Additional comment

The first attached graph shows the given equation rewritten as two functions. The solution is where those functions have equal values: the point(s) where the graphs intersect.

We often find it more convenient to rewrite equations like this to the form f(x) = 0. Here, that might mean we define ...

  f(x) = |y -4| -|y +10|

Then the solution is found on the graph at the x-intercepts. The graph in the second attachment shows this solution, and clearly shows the changes in behavior at x = -10 and x = 4.

The equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5

From the question, we are to determine the equation that could be used to determine, m, the average number of miles she would have to ride to meet her goal

From the given information,

"Arianys wants to ride her bicycle 55.5 miles"

and

"She has already ridden 19 miles"

Thus,

The number of miles she needs to ride more is

55.5 miles - 19 miles

= 36.5 miles

If m is the average number of miles she would have to ride for 5 more days to complete her goal,

Then, we can write that  

m = 36.5/5

OR

m = (55.5 - 19)/5

Hence, the equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5

Answer:

F=9/5c+32

Step-by-step explanation:

Multiply both sides by 9/5 to cancel out the 5/9 on the right side of the equation. This gives you:

9/5C = F-32

C=F−32

Then add 32 to both sides, giving you:

9/5C + 32 = F

C+32=F

Thus, you have:

F= 9/5C + 32F=

C+32

Answer:

[tex]F= \frac{9}{5}C + 32[/tex]

Step-by-step explanation:

Multiply both sides by 9/5 to cancel out the 5/9 on the right side of the equation. This gives you:

[tex]\frac{9}{5}C = F-32[/tex]

Then add 32 to both sides, giving you:

The variance and standard deviation for the frequency of pupils per teacher in some states of US is; Variance= 4.62 = 4.6 and Standard Deviation = 2.14 = 2.1

Variance(σ²) is a measure of dispersion. A measure of dispersion is a quantity that is used to check the variability of data about an average value. Data can be of two types - grouped and ungrouped. When data is expressed in the form of class intervals it is known as grouped data.

The standard deviation(σ) of a random variable, is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation.

That means;

Standard Deviation = √variance.

For the given data the sum of frequencies = 1+16+11+7+1+2= 38.

Midpoint is 12,15,18,21,24,27.

ni x mi = 12,240,198,147,24,54.

Sum of ni + mi = 675.

Mean (u) =  17.76

mi - u is -5.76,-2.76,0.24,3.24,6.24,9.24.

(mi - u)² is 33.17,7.61,0.057,10.49,38.93,85.37.

Sum of (mi - u)² = 175.62.

Variance = Sum of (mi - u)² / sum of frequencies

= 175.62/38

= 4.62 = 4.6.

Standard deviation = √variance.

= √4.62

= 2.14 = 2.1.

Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry.

X, Y, Z are collinear points on the same segment, and Y is between X and Z.

As given Y is between X and Z

We can write,: YZ+XY=XZ

If, XY=11

XZ=13

Replace XY and XZ values in above equation

So, YZ+XY=XZ

YZ+11=13

YZ=2

Using proportions, it is found that the exact value of 41% of 379 is of 155.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The proportion of 41% of 379 is given as follows:

0.41 x 379 = 155.39.

Since 0.39 < 0.5, the exact value is rounded to 155.

Step-by-step explanation: hope it helps.

The number of dimes that we have are 3, the number of nickels are 6 and the number of quarters are 5.

Let the number of dimes be x.

So, we get that:

The number of quarters will be = x + 2

The number of nickels will be = 2 x

Now, 1 dime = $0.10.

1 nickel = $ 0.05

1 quarter =  $ 0.25

Amount of dimes = 0.10 x

Amount of nickels = 0.10 x

Amount of quarters = 0.25 x + 0.5

Total amount of coins = $ 1.85

So, we get the equation as:

0.10 x + 0.10 x + 0.25 x + 0.5 = 1.85

0.45 x = 1.35

x = 135 / 45

x = 3

Dimes = 3

Nickels = 6

Quarters = 5

Therefore, we get that, the number of dimes that we have are 3, the number of nickels are 6 and the number of quarters are 5.

The solution to the given quadratic equation using the completing the square method is t = -5/2 ±√29/4

Given the quadratic equation expressed as;

t^2+5t−1=0

Add 1 to both sides

t^2+5t−1 + 1 = 0+1

t^2 + 5t = 1

Take the square of half of the coefficient of t to have:

t^2 + 5t + (5/2)^2 = 1 + (5/2)^2

(t+5/2)^2 = 1+25/4

(t+5/2)^2 = 29/4

t + 5/2 = ±√29/4

t = -5/2 ±√29/4

Hence the solution to the given quadratic equation using the completing the square method is t = -5/2 ±√29/4

27.5 years old

Step-by-step explanation:

We are given the formula: [tex]P=0.006A^{2} -0.02A+120[/tex] relating a patient's pressure to age.

We are also given the value for pressure (P) as 124 mmHg and need to find age (A). In order to do this, we can substitute the value 124 for P in the equation and solve the quadratic equation to obtain A:

[tex]124=0.006A^{2} -0.02A+120[/tex]

1. Set equation to 0 by subtracting 124 from both sides:

[tex]124-124=0.006A^{2} -0.02A+120-124\\= > 0.006A^{2} -0.02A-4=0[/tex]

2. Solve equation using a calculator:

It should give the solutions: [tex]A= 27.54, -24.2[/tex]

It doesn't really make sense for someone's age to be negative, therefore we can accept the positive solution as our answer.

Step-by-step explanation:

We will assume “a number” is “a”. When it is cubed it will be represented by

= “a³”.

When we multiply the number with 5 then the new cube will be

= (5a)³

Now distribute the exponent to the factors inside the parentheses.

= 125a³

What happens in the parentheses is 5*5*5 = 125

a*a*a = a³

So by multiplying your number with 5 it gets increased by 125 times.
