Answer:

y= -1/4x + 9

Step-by-step explanation:

When given the point (8,7) and the slope -1/4, you have to convert this into a formula called point slope form. This is the formula:

y - y1 = m(x - x1)

First, label the given information.

-1/4= m (slope)

8= x1 (the first x given)

7= y1 (the first y given)

Then, plug in the values into the equation

y - 7 = -1/4(x - 8)

After, do the property of distribution by multiplying the -1/4 with whatever is in the bracket

-1/4 multiplyed by x= -1/4x

-1/4 multiplyed by -8= 2

Next, bring the 7 to the other side of the equal sign by adding the 7 from one side to the 2. Then combine like terms

y - 7 = -1/4x +2

 +7            +7  

This gets you your answer:

y = -1/4x +9

Answer:

y = 3x - 1

Step-by-step explanation: All you have to do here is solve the equation for y. When you add 5 to both sides, you are left with 3(x-2) + 5. Now, you just have to open the parentheses, giving you 3x-6+5, or 3x-1.

Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D

Step-by-step explanation:

The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where

a is the altitude measured in feet

T(a) is the boiling point of water in degree

The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)

By comparing between the form of the function and the given function

∴ m = -0.0018 ⇒ degrees per foot

∵ The sign of the slope is negative

∵ The slope = Δf(x)/Δx

- That means T(a) is decreasing function

∴ The boiling point is decreases when the altitude increasing

∵ -0.0018 =  degrees per feet

∴ The boiling point decreases by 18 degrees as the altitude

   increases by 10,000 feet or the boiling point decreases by 1.8

    degrees as the altitude increases by 1,000 feet

The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

Answer:

E. None of these

Step-by-step explanation:

Points: (11, -4), (13, -7)

slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2

y - y1 = m(x - x1)

y - (-4) = (-3/2)(x - 11)

y + 4 = (-3/2)x + 33/2

y + 8/2 = (-3/2)x + 33/2

y = (-3/2)x + 25/2

Answer: E. None of these

Step-by-step explanation:

A(11,-4) B(13,-7)

x1 y1 x2 y2

y=mx+c

-4=11m+c -(i) -7=13m+c -(ii)

Subtract equation (ii) from (i)

-7=13m+c

-4=11m+c

+ - -

-3=2m

2m=-3

m=-3/2

put m=-3/2 in equation (ii)

-7=13*(-3/2)+c

c=-7+39/2

c=(-14+39)/2

c=15/2

y=mx+c

y=-3/2x+15/2

y=(-3x+15)/2

2y=-3x+15

Step-by-step explanation:

              Statements                                     Reasons

1). 17 - 3(w + 5) = 6(w + 5) - 2w            1). Given

2). 17 - 3w - 15 = 6w + 30 - 2w            2). Distributive property

3). -3w + 2 = 4w + 30                           3). Addition property of equality

4). -7w + 2 = 30                                    4). Subtraction property of equality

5). -7w = 28                                          5). Subtraction property of equality

6). w = -4                                              6). Division property of equality

Answer:

x = 42

Step-by-step explanation:

the angles are considered congruent so the equation would be 4x-27 = 3x+15

add 27 to both sides: 4x= 3x +42

subtract 3x from both sides: x= 42

Answer: x > -1

Step-by-step explanation:

1) Subtract 5 from both sides

-3(4x - 5) < 27

2) Divide both sides by -3 (Remember to change the inequality sign to face the other way, because you have multiplied/divided by a negative number)

4x - 5 > -9

3) Add 5 to both sides

4x > -4

4) Divide by 4 on both sides

x > -1

Answer:

answer is c (plato users)

Step-by-step explanation:

The point is a point where the graph of y = (x − 5)(x2 − 7x + 12) crosses the x-axis is  (4,0).

The answer is option C (4,0)

            slope(m)=tan∅=y axis/x axis.

Straight line graphs show a linear relationship between the x and y values.

solving the equation:-

⇒y = (x − 5)(x2 − 7x + 12)

⇒y= 2x²-7x²+12x-10x+35x-60

⇒y=-5x²+37x-60

Step-by-step explanation:

A function assigns the values. The time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.

A function assigns the value of each element of one set to the other specific element of another set.

Given that the formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet.

Now, in order to calculate the time, it will take for the rock to fall from the height of 125 feet, simply substitute the height of the rock from which it is dropped in the formula given.

Therefore, the time it will take for the rock to reach the ground from a height of 125 feet is,

t = √h / 4

t = (√125) / 4

t = (5√5) / 4

t = 2.795 seconds

Hence, the time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.
