Expand and simplify (x + 3)(x - 1)

Answer:

MA = 7, Actual

Step-by-step explanation:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantage

According to the question,

Input force,

Output force,

As we know the formula,

→ [tex]MA = \frac{Out\ force}{Inp \ force}[/tex]

By substituting the values, we get

          [tex]= \frac{350}{50}[/tex]

          [tex]= 7[/tex]

Thus the above answer is correct as well as it is actual.

Step-by-step explanation:

3x-3y=4

3y= 3x -4

y= x-4/3

-3x+3y=3

3y= 3x+3

y= x +1

.....

Since they have the same slope and different y-intercepts , then there are no solutions for these equations because they're parallel.

Answer:

D because you divide both sides by x.

Step-by-step explanation:

They are equivalent if you divide both sides by x for A

Answer:

x=-2

Step-by-step explanation:

First you divide both -33 and 3 by 3, should have -11=(x-9) afterwards. Then you want to Move the x to the right side of the equal sign and the -11 to the left of the equal sign. Should look like this: x=9-11. Then subtract and get -2.

Answer: x = 1

3x + 4 = 7

subtract 4 from both sides

3x = 3

x = 3/3 = 1

Answer:

30

Step-by-step explanation:

180 degrees = Triangle

Angle 1 = 60

angle 2 = 90 because it's a right triangle

Angle 3 = 180 - (60+90) = 30

60 + 90 = 150

180 - 150 = 30

Answer:

y-intercept = -2

Step-by-step explanation:

Use the point-slope form of a line to do this problem.

[tex]y - y_{1} = m(x - x_{1})[/tex]

y - 4 = 3(x - 2)  Now change the equation to slope-intercept form

y - 4 = 3x -6

y = 3x - 2   So m = 3  b = y-intercept = -2

A) [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

[tex]\frac{7}{4}[/tex]

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

[tex]-\frac{7}{4}[/tex]

A. is correct.

Answer:

11 17/21 cm²

Step-by-step explanation:

Given

Length = 2 2/7cm

Width = 5 1/6cm

Area of the rectangle = Length * width

Area of the rectangle = 2 2/7 * 5 1/6

Area of the rectangle = 16/7 * 31/6

Area of the rectangle = (16*31)/(7*6)

Area of the rectangle  = 496/42

Area of the rectangle  = 11 34/42

Area of the rectangle  = 11 17/21

Hence the Area of the rectangle  is 11 17/21 cm²
