Write the slope-intercept form of the equation of the line described.
1) through (2, 2), parallel to y=x+4

Answers

Answer:

Slope intercept form: y=mx+b; where m is the slope and B is the y intercept

For 2 lines to be parallel they must have the same slope. Thus, the slope of the new line is going to be 1.

To find the y intercept plug in the slope and the x, y into the equation y=mx+b:

y=mx+b

y=1x+b

2=1(2)+b

2=2+b

0=b

b=0

Now that we have your slope and y intercept we can make the equation:

y=1x+0

y=x

answers: -7 1/2, -3/10, -2/15, -3 1/3

Answers

Answer: -7 1/2

Step-by-step explanation:

The required number would be -3/10.which is the correct answer would be option (B).

What is the number system?

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

We have been given that two-thirds of a number is equal to a negative one-fifth.

Let the number would be x

According to the given question, the required solution would be as:

⇒ (2/3)x = -1/5

Divided by (2/3) both sides of the above equation,

⇒ (2/3)x/ (2/3) = (-1/5)/(2/3)

⇒ x = (-1/5)/(2/3)

Reciprocal the term in the numerator,

⇒ x = (-1/5) × (3/2)

Apply the multiplication operation, and we get

⇒ x = -3/10

Therefore, the required number would be -3/10.

Hence, the correct answer would be option (B).

Answer:

(i) √23(i) 196√23

Step-by-step explanation:

Given equation:

x² - 10x + 2 = 0

Roots are:

α and β

Sum of the roots:

α + β = -b/a ⇒ α + β = -(-10)/1  ⇒ α + β = 10

Product of the roots:

αβ = c/a ⇒ αβ = 2/1 ⇒ αβ = 2

Finding the following:

(i)

1/β - 1/α =(α - β)/αβ =√(α - β)² / αβ =√((α + β)² - 4αβ) / αβ = √(10² - 4*2) / 2 =√92 / 2 =2√23 / 2 =√23

(ii)

α³ - β³ =(α - β)(α² + αβ + β²) =√(α - β)²× ((α + β)² - αβ)√((α + β)² - 4αβ) × ((α + β)² - αβ) =√(10² - 4*2) × (10² -2) =√92 × 98 =2√23 × 98 =196√23

ANSWER:

y = 2/3x + 2

EXPLANATION:

Write the equation in slope intercept form
y=mx+b
-2x+3y=2
3y=2+2x
y=2/3x+2/3

From the slope intercept form, we know that the slope is m=2/3

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Substitute the slope 2/3 and the point (3,4) in the point slope form: y-y1=m(x-x1) which we get from m=y2-y1/x2-x1
y - (4) = 2/3 • (x-(3))

Simplify it
y - 4 = 2/3 • (x-3)

Solve for y
y - 4 = 2x/3 - 2
y = 2x/3 - 2 + 4
y = 2/3x + 2

Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

Let the numbers be x, y and z

x + y + z = 242y = z + 2z = x + y

Solving by substitution:

x + y + z = z + z = 242z = 24z = 12

2y = z + 22y = 12 + 22y = 14y = 7

z = x + yx = z - y x = 12 - 7 = 5

The answer:

x = 5, y = 7, z = 12

Answer:

Step-by-step explanation:

Let's evaluate each choice

1) Generally, it is possible that the taller a person is, that his/her shoe size would generally get bigger also. Hence we can say that it is possible that there is a function correlation between height and shoe size.

2) hair length can be cut down short or left long regardless of the height of a person, so we cannot say for sure that hair length correlates with height. Hence this is probably not a function)

3) hair color has no bearing on a persons age. hence this is probably not a function.

4) student ID number doesn't depend on the name of the student. Hence this is probably not a function.

Consider the conditional statement of N is the midpoint of CD then CD =2CN what is the hypothesis

Answers

Answer:

Step-by-step explanation:

If N is the midpoint of CD, it means that N bisects the line CD. Hence;

CN + CN = CD

2CN = CD

Rearrange;

CD = 2CN (proved)

After 4 days, a plant is measured to be 10 inches tall. Later, after a total of 20 days, then height is measured to be 18 inches. What is the rate of growth for the plant? This is supposed to be for slopes in Algebra 1.

Answers

Given :

After 4 days, a plant is measured to be 10 inches tall.

Later, after a total of 20 days, then height is measured to be 18 inches.

To Find :

The rate of growth for the plant.

Solution :

We know, rate is given by :

[tex]Rat e=\dfrac{\text{Change in height}}{\text{Time taken}}\\\\Rate = \dfrac{18-10}{20-4}\\\\Rate = 0.5 \ inch/day[/tex]

Therefore, rate of increase of height is 0.5 inch/day .

Hence, this is the required solution.

k=zy/x

k=6×4/3(z=6,y=4,x=3)

k=24/3

k=8
