What equation represents the slope intercept form of the line below Y intercept =(0,-2) slope = 2/3

Answers

Answer: [tex]y = \frac{2}{3} x - 2[/tex]

Step-by-step explanation:

The slope intercept form is y = mx + b

Where m is our slope and b is our y-intercept

We're given a slope of 2/3

We're given a y-intercept of -2

Substituting into y = mx + b gives

[tex]y = \frac{2}{3} x - 2[/tex]

Answer:

y = (2/3)x - 2

Step-by-step explanation:

Use the slope-intercept form y = mx + b.  Here b = -2 and m = 2/3.  Making these replacements, we get:

y = (2/3)x - 2

Slove (3x-2)=(2x-1)/(2) show step by step

Answers

Answer:

x= 3/4

Step-by-step explanation:

[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]

2(3x - 2) = (2x - 1)

6x - 4 = 2x -1

4x = 3

x= 3/4

Answer:

x=3/4

Step-by-step explanation:

Remove parentheses.

3x-2=\frac{2x-1}{2}3x−2=22x−1

Multiply both sides by 22.

6x-4=2x-16x−4=2x−1

Add 44 to both sides.

6x=2x-1+46x=2x−1+4

Simplify  2x-1+42x−1+4  to  2x+32x+3.

6x=2x+36x=2x+3

Subtract 2x2x from both sides.

6x-2x=36x−2x=3

 

Simplify  6x-2x6x−2x  to  4x4x.

4x=34x=3

 

Divide both sides by 44.

x=\frac{3}{4}x=43

Answers

Answer:

No

Step-by-step explanation:

Forgive me if i'm wrong lol

so the square root of 7 is 2.64, 2.64 minus 2.64 is 0, and it is not rational since it can't be written as a fraction.

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?​

Answers

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating

Answers

Answer:

Option D

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:

c² = a² + b²

From the options, option d is the correct option.

For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:

c² = a² + x²

x² = c² - a²

x = √(c² - a²)

Therefore the other leg would be √(c² - a²)

They need to first decide on the planning period (the benefits should be calculated over N years, and N should be determined). If N is too large, then the future benefits in those years (e.g. 70 years from now) will have a very low present value. Therefore, the engineer would like to cut off the planning period after a point when the present equivalent of benefits becomes less than 6.25% of that future benefit. If the interest rate is 8%, use the rule of 72 to determine the duration of the planning period (N).
