Answer:

23 is the right answer of this question

Answer:

1 is (2.-2) but i cant see the rest

Step-by-step explanation:

Answer:

2. m = 1

3. y - (-1) = 5 (x - 4)

4. y = 5x - 21

Step-by-step explanation:

Work for #2

m (slope) = [tex]\frac{y2 - y1}{x2 - x1} \fracyx}[/tex]

m = [tex]\frac{-1 - 2}{-2 -1}[/tex]

m = [tex]\frac{-3}{-3}[/tex]

m = 1

Work for #3

y = -1/5x + 3 and through (4, -1)

The slope of a perperndicular line is the negative reciprocal. So, it is 5.

Plug this number into point-slope form. Use the points you were given (4,-1) in the equation as well.

y - y1 = m (x - x1)

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20 (Only if you are supposed to simplify it)

Work for #4

Finish solving the equation

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20

y = 5x - 20 - 1

y = 5x - 21

Answer:

-8

Step-by-step explanation:

Answer:

g(3) = 4

Step-by-step explanation:

The question means what is the value of y when x = 3

Locate x = 3 on the x- axis. Go vertically up until the dot is met and read off the corresponding value on the y- axis, that is y = 4

Thus when x = 3 then y = 4, or

g(3) = 4

The value of g(3) from the graph given is 4

The given diagram is a graph in the xy-plane with different coordinate points.

Hence we can conclude that the value of g(3) is 4

5x+y=8

Step-by-step explanation:

[tex]y + 5x = 8[/tex] is a standard form of equation.

What is standard form?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. If the equation is given in this form, finding both points of intersection (x and y) is quite easy. This form is also very useful for solving systems of two linear equations.

By some examples,we can understand the concept more easily.

Example -1,

[tex]2x + 3y = 2[/tex] is a standard form of equation.

Example -2,

[tex]5x + 7y = 2[/tex] is a standard form of equation.

Example -3,

[tex]5x = y - 5[/tex] is not a standard form of equation.

Given equation is [tex]y = - 5x + 8....(1)[/tex]

We want to find standard form for the given equation.

Now,

[tex]y = - 5x + 8[/tex]

We are separating variable and constant part.

[tex]y + 5x = 8[/tex]

According to rule,it is a standard form of equation.

Answer:

slope (m) = -50 or -50x

Step-by-step Explanation

I'm assuming that the x-axis is divided by 1 minute segments.

The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"

Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute

Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for

Answer:

Independent variable: Time in minutes

Dependent variable: The elevation in feet

Slope: -50

Y-Intercept: -100

Answer:

The three digit number is;

996

Step-by-step explanation:

The three digit can be written xyz

ones digit is equal to 1/3 the sum of the two other digits

z = 1/3(x + y)

x + y + z = 24

Tens digit is same as hundreds digit

That means x = y

z = 1/3 (x + x) = 2x/3

So;

2x/3 + x + x = 24

Multiply through by 3

2x + 3(2x) = 72

8x = 72

x = 72/8

x = 9

x = y = 9

z = 1/3(18)

z = 6

Answer:

2,160 pencils

Step-by-step explanation:

Large boxes = 12

Small boxes = 18

Each large box contains 144 pencils . Each small box contains 24 pencils

Total pencil in large boxes = Total large boxes × number of pencils per box

= 12 × 144

= 1,728 pencils

Total pencil in small boxes = Total small boxes × number of pencils per box

= 18 × 24

= 432 pencils

Estimate the total number of of pencils

Total number of pencils = total pencils in large boxes + total pencil in small boxes

= 1,728 pencils + 432 pencils

= 2,160 pencils

Answer:

  -6

Step-by-step explanation:

The average rate of change on the interval [1, 3] is ...

  m = (g(3) -g(1))/(3 -1) = (-20 -(-8))/2 = -6

The average rate of change is -6 on the interval from 1 to 3.

Answer:

Step-by-step explanation:

∠A + ∠B = 180

where ∠A = 6x - 18

           ∠B = 14x + 38

first step is to solve for x:

6x - 18 + 14x + 38 = 180

6x + 14x = 180 + 18 - 38

20x = 160

x = 160 / 20

x = 8

now substitute x=8 into angle A

∠A = 6x - 18

∠A = 6(8) - 18

∠A = 30°

Answer:

x = -5

Step-by-step explanation:

f(x) is the same thing as y. so when y=-3, find that point and the x is -5

The answer to the given problem can be stated as, "If f(x) = -3, then x = -5.

A function y = f(x) is defined as a one to one relation between sets X and Y. The set X is called the domain while Y is called the range of f(x).In order to find the different values of f(x) for different x on a graph, draw perpendicular lines to both the axis.

The graph given in the problem shows different points lying on it.

In order to find the value of x at f(x) = -3, draw a perpendicular line from the graph at which the value of f(x) is -3.

The x coordinate obtained is given as x = -5.

Hence, the required value of x at f(x) = -3 is -5.
