The point slope form comes from the definition of slope as a measure of the change in  

y

for a given change in  

x

in passing from point 1 to point 2, i.e.:

The only difference here is that you do not have 2 points but only one!

So you have: the value of  

m

and the coordinates of one point, say, point 1. So we can write in (1):

where the coordinates of the other point are the unknown

Answer:

R

Step-by-step explanation:

Look at the X value, 3.5, and draw a line from 3.5 up on the X axis.

Look at the Y value, 2.5, and draw a horizontal line on the y axis. Your point is at R.

Answer:

Step-by-step explanation:

2x +15 +2x +5 = 180

4x = 180 - 20

x = 160/4

x = 40

TVZ + 2x +5 =180

TVX +2(40) = 180 -5

TVX = 175 - 80

TVX = 95

Answer:

Step-by-step explanation:

1/2 of 24 is 12

24 + 12 is 36

1/2 of 30 is 15

30 + 15 is 45

Answer:

The answer is 42

Step-by-step explanation:

36 miles minus 24 mil3s equals 12 so you plus 30 minutes 12 eq 42 minute.

Step-by-step explanation:

100 quarters, each quarter being 1/4 of a dollar, 100x.25= 25. And 100 half dollars, 1/2 of a dollar, 100x.50=50

Answer:

4.5 hot dogs per minute

Step-by-step explanation:

rate of change=hot dog/minutes=54/12=4.5

Answer:

4.5 Hotdogs per Minute

Step-by-step explanation:

Rate of change is found by dividing the total amount of an object, in this case the hotdogs, by the amount of time.

We know that Nathan has 54 hotdogs and that he eats them in 12 minutes.

Therefore: [tex]\frac{54}{12}[/tex] is the rate of change.

This can be simplified to 4.5 as the rate of change.

Answer:

k = 5

Step-by-step explanation:

The formula for coefficient of proportionality is y = kx.

In the given problem, the Area of a rectangle corresponds to "y" in the constant of proportionality formula, and "x" is still the same. Since the formula for the area of a rectangle is: A = L × W, then:

A = y

L = k

W = x

y = kx is the same as A = LW or A =  L × W

Thus, we're looking for the value for k, which corresponds to the length (L) (which has a constant value).

Below are the calculations for the missing values in the table:

We'll start with x = 0.14, and A = 0.7 since we're given the values for them. We could plug these values into the formula for the Area of a rectangle to find the constant value of the length (L):

A = L * W

0.7 = L * 0.14

Divide both sides by 0.14 to isolate L:

0.7/0.14 = (L * 0.14)/0.14

5 = L  ←← Keep in mind, this is the coefficient of proportionality.

x = 3.1:

A = L * W

A = 5 * 3.1

A = 15.5

x = 2.5:

A = 5 * 2.5

A = 12.5

x = 1.2:

A = 5 * 1.2

A = 6

x = 0.9:

A = 5 * 0.9

A = 4.5

Next, we're given the values for the Area, but we're missing the values for x. However, we already have the value for L = 5. We could still follow the same process by plugging in the values into the formula:

A = 0.3:

A = L * W

0.3 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.3}{5} = \frac{5 * W}{5}[/tex]

0.06 = W

A = 0.1:

A = L * W

0.1 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.1}{5} = \frac{5 * W}{5}[/tex]

0.02 = W

Therefore, k = 5.

Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

Answer:

Sorry ineed point ehhh thnks po sa points:)

Step-by-step explanation:

the car went 25 meters in 1 second.

that creates this ratio 25 m/s or

formally fully correct 25/1 m/s.

to get the speed in km/h we need to bring the denominator of that ratio from 1 second to 1 hour.

we do that by multiplying it by 3600, as there are 3600 second in 1 hour.

to keep the overall value of the ratio we need to multiply also the numerator with the same factor.

so,

25/1 × 3600/3600 = (25×3600)/3600 =

= 90000 meters /1 hour

how many km (kilometers) are 90000 meters ?

1 km = 1000 m

so,

90000 m = 90000/1000 km = 90 km

therefore, or full answer is

the car's speed was 90 km/h.

Step-by-step explanation:

A translation using the vector < 3, - 4 > , means

Add 3 to the x- coordinate and subtract 4 from the y- coordinate, so

M (- 3, - 2 ) → M' (- 3 + 3, - 2 - 4 ) → M' (0, - 6 )

N (- 1, 4 ) → N' (- 1 + 3, 4 - 4 ) → N' (2, 0 )

P (2, 4 ) → P' (2 + 3, 4 - 4 ) → P' (5, 0 )

Q (4, - 2 ) → Q' (4 + 3, - 2 - 4 ) → (7, - 6 )

Step-by-step explanation:

[tex]\frac{(6n^{3}-9n^{2} +5n+7)(n-5) }{n-5}[/tex]

2) Cancel [tex]n-5[/tex].

[tex]6n^{3} -9n{2} +5n+7[/tex]

Answer:

y axis: (0, 12)

x axis: (18, 0)

Quadrant I: (4.5, 10.6)

Quadrant II: (-15, 21)

Quadrant III: (-3/4, -4 1/9)

Quadrant IV: (3, -7)

Step-by-step explanation:

Integers used for each Quadrant.

Quadrant one: x axis = positive, y axis = positive

Quadrant two: x axis = negative, y axis = positive

Quadrant three: x axis = negative, y axis = negative

Quadrant four: x axis = positive, y axis = negative

(0,12) = goes to the y axis

(3,-7) = goes to quadrant 4

(-15,21) = goes to quadrant 2

(18,0) = goes to the x axis

(4.5,10.6) = goes to quadrant 1

(-3/4, -4 1/9) = goes to quadrant 3

a. Point-slope form is: y - y0 = m(x - x0). Plugging in our values, we get: y - 2 = -3(x - 11). Typically we can just leave it like this, but for the sake of simplifying it down to slope-intercept form, it would be y = -3x + 35.

b. y - 2 = -3((0) - 11)

y - 2 = 33

y = 35.

c. y = -3x + 35.
