What is the equation of the line that passes through (4, 3) and (-4, -1)?

y = 2 x + 7
y = + 1
2 x + 1
y = + 7

Answer:

y = 1/3x - 2

Slope = 1/3

y- intercept = -2

Step-by-step explanation:

To find the slope and y-intercept, first put the equation in y = mx + b format, Where m is your slope and b is your y-intercept.  

Step one:  Subtract x from both sides

To translate x over to the right side of the equation, subtract x from both sides, leaving you with this equation:

x - x -3y = -x + 6; which simplifies to:

-3y = -x + 6

Step Two: Divide Every Term By Negative 3

To get y alone by itself we need to cancel out -3 on the right side of the equation, to do that you must divide every term by negative 3 leaving you with this equation:

[tex]\frac{-3}{-3}[/tex]y = [tex]\frac{-1}{-3}[/tex]x + [tex]\frac{6}{-3}[/tex]; which simplifies to:

y = 1/3x - 2

M, slope, = 1/3

B, y-intercept, = -2

Answer:

1244 Ibf(Pounds force)

Step-by-step explanation:

The formula for Total force on a piston when given the diameter of the bore area =

F = P × π × d²/4

P = 150 lb/sq.In

π = 3.14

d = 3.25 in

Hence,

F = 150 lb/sq.In × 3.14 × 3.25 in /4

= 4974.9375 ÷ 4

= 1243.734375 Ibf(Pounds force)

Approximately = 1244 Ibf(Pounds force)

Answer:

The probability is 4/11

Step-by-step explanation:

Here, we want to get the probability of getting an even number

Using the given ratio, the total of the numbers is 4 + 7 = 11

The number of even numbers is 4

So the probability of getting an even number will be the number of even numbers divided by the total of the numbers

We have this as 4/11

Answer:

~27.764982043070833894247682407876

Step-by-step explanation:

First, we can add 8+5.5+8 because of the two sides which are 8 and one that is 5.5. That is 21.5.

Then, we must find the diagonal edge. To do that, we can use the pythagorean theorem. It makes a triangle, so given that a^2+b^2=c^c, we can say that 3^2+5.5^2=c^c. Using a calculator, we can find the square root of 39.25, then add it to 21.5.

Answer:

(12. 21)

Step-by-step explanation:

Given the coordinate (5, 9), if it is dilated by a factor of 2, the resulting coordinate will be expressed as;

P = 2(5, 9)

P = (2(5), 2(9))

P = (10, 18)

If it is now translated 3 up and 2 right, then the final coordinate will be at;

P' = (10+2, 18+3)

P' = (12, 21)

Hence the final image will be at (12. 21)

Answer:

A- 0.68

Step-by-step explanation:

0.58 is most likely to be the population parameter, since the sample proportions center around this value.

Option B is the correct answer.

We have,

When many large samples are taken from a population, the sample proportions should converge to the population proportion.

If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.

In this case,

Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.

Therefore,

0.58 is the most likely population parameter.

area of a trapezoid is base + base divded by 2 then times that by the height

25 x 15 = 375

Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:

y = 3/2* x + b, provided b ⇒ y - intercept,

( 4 ) = 3/2 * ( 7 ) + b,

4 = 21/2 + b,

b = 4 - 10.5,

b = -6.5

Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

Answer:

Step-by-step explanation:

Here, we need to know about the concept of the alternate interior angle theorem. This says that the alternate interior angle of two parallel lines formed with one transversal is equal. For a more graphical explanation, please refer to the attachment below.

--------------------------------------------------------------------------

Given

∠GBD=4x+84

∠EFC=16x

m∠GBD=m∠EFC

Solve

4x+84=16x ⇔ Given

4x+84-4x=16x-4x ⇔ Subtract 4x on both sides

84=12x ⇔ Simplify

84/12=12x/12 ⇔ Divide 12 on both sides

x=7 ⇔ Simplify

Substitute the x value into each angle expression

∠GBD=4x+84=4(7)+84=28+84=112

∠EFC=16x=16(7)=112

Answer:

Its C

Step-by-step explanation:

Answer:

C. 3

Step-by-step explanation:

First I'll solve y + 1 = 3x - 12 for y.

y + 1 = 3x - 12 All you need to do for this first part is subtract 1 from both sides.

y = 3x - 12 - 1

y = 3x - 13

I'll use the point for x being 6, and x being 12.

3(6) - 13

18 - 13

5

y is 5 when x is 6. (6, 5)

3(12) - 13

36 - 12

y is 23 when x is 12. (12, 23)

The formula for slope is y2-y1/x2-x1

(23 - 5)/(12 - 6) Subtract 5 from 13, and then subtract 6 from 12.

18/6 Divide 18 by 6.

Percent error is 44.4%

Step-by-step explanation:

Here, we want to get the percent error

From the question, prediction is 54 while actual value is 78

from the formula given;

Percent error = |prediction-actual|/actual * 100%

so we have

|54-78|/54 * 100%

= 24/54 * 100% = 44.4%
