Answer:

m = 4/5 (slope)

_____________________________

y = 4/5x - 1 (slope intercept)(y = mx + b)

- 4x + 5y = - 5 (standard form)(Ax + By = C)

y + 5 = 4/5(x + 5) (point slope)(y - y1 = m(x - x1))

Step-by-step explanation:

All you need to do is remember the equation for slope: m = y2-y1/x2-x1

Where your first point is (x1,y1), and your second point is (x2,y2), and m is slope(rate of change : change in y over change in x).

Your first point starts with the smallest x: (-5,-5), then your second point is the greater x: (5,3)

Then just substitute, and solve:

y2-y1/x2-x1 →

3-(-5)/5-(-5) = 3+5/5+5 = 8/10 = 4/5

Extra information:

point slope:

y-y1 = m(x-x1).

Where (x1,y1) is the first point, (x,y) is the second point, and m is the slope. (note: the second point does not have 2 as a subscript so it can be set to slope intercept(y = mx + b) as an equation. This is because you could be given one point, and a slope, and be told to find the other)

Then just plug the coordinates into the equation, and solve for the equation of this line.

Since we already know what the slope is, we can just solve for the general equation given one point:

y-y1 = m(x-x1)

y+5 = 4/5(x+5). (point slope)

y + 5 = 4/5x + 4

-5 -5

____________

y = 4/5x - 1

(slope intercept)

Given slope, another way to find the y intercept is to multiply the current x coordinate by the slope, and add it to the current y value.

given a point (5,3), and a slope of 4/5. The line will be y = slope × x + (y2 - (m × x2)),

y = 4/5 × x + (3 - (4/5 × 5))

y = 4/5x + (3 - 4)

y = 4/5x - 1

Answer:

if I read it right and it is just asking for the slope then -1.2 should be the answer

Answer:

.31 kg

Step-by-step explanation:

F=kx

F = the force of the spring

k = the spring constant

x = the spring displacement (stretch or compression)

we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F

let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N

so 5.39=k(1.2 centimeters)

Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)

divide 5.39 by .012 to get 449.17

our k is 449.17

Now for our problem, we are going to find the mass.  

Do this by putting what we already know into the problem.

F=449.17(.67 centimeters)

Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)

This will result in F=3.01 but the problem is asking for mass, not force.

Use the formula 9.8(kg)=F

9.8(kg)=3.01

kg=.31

solution: .31 kg

Answer:

120°

Step-by-step explanation:

A line must add up to 180°.

The sum of angles in a triangle also adds up to 180°.

Step 1: Find measures interior angles.

3x = 180

x = 60°

Step 2: Find measures of exterior angels.

x + 60 = 180

x = 120°

Answer:

120°

Step-by-step explanation:

The sum of all interior angles is found using (n - 2)180

n is the amount of angles inside the polygon (in this case, 3). Plug in 3 for n:

(3 - 2)180 = (1)(180) = 180

There are 3 sides in a triangle. Divide the total (180) with 3:

180/3 = 60

Next, Subtract 60 from 180:

180 - 60 = 120

120 is your exterior angle.

120° is your answer.

Question:

Convert the numbers to standard from 7.23 × 10^(-10)

Answer:

7.23 billionths or 0.000000000723

Explanation:

First, convert the standard form of 10^(-10) to 1 ÷ 10^(10). Thus, the standard operation would be:

7.23 ÷ 10^10 or 7.23 ÷ 10,000,000,000

Hence, you could write it in a reciprocal of a billion, which is a billionth. You could write it in the form of 7.23 billionths or just write it 0.000000000723.

Answer:

10 1/3

Step-by-step explanation:

Convert mixed numbers into improper fractions (whole number × denominator + numerator)

25 2/3 and 15 1/3

25 × 3 + 2 = 75 + 2 = 77

Put the number over the same denominator

77/3

15 × 3 + 1 = 45 + 1 = 46

Put the number over the same denominator

46/3

77/3 - 46/3

They have common denominators so we can simply subtract the numerator values

77 - 46/3

f(x) = -(x+3)(x-4)

f(x) = -[tex]x^{2}[/tex]+x+12

Step-by-step explanation:

The equation of the parabola is y = -(x + 3) (x - 4).

In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

Given that a graph of a parabola, we need to find the equation of the parabola,

Intercept form equation of the parabola:

y = a(x - p) (x - q), x-intercepts are (-3, 0) and (4, 0).

x = -3 ------ x + 3 = 0

x = 4 ------- x - 4 = 0

y = a(x + 3) (x - 4)

It passes through (0, 12). Substitute (x, y) = (0, 12)

12 = a(0+3)(0-4)

12 = -12a

a = -1

Intercept form equation of the parabola:

y = -(x + 3) (x - 4)

Hence, the equation of the parabola is y = -(x + 3) (x - 4).
