Answer:

4x-3

Step-by-step explanation:

(7x-5) - (3x-2)

aka

(7x-5)  -1 (3x-2)

first distribute the -1 into (3x-2)

-3x+2

so

(7x-5)+ -3x+2

next combine like terms

7x-3x=4x

so

4x-5+2

then

-5+2=-3

so

4x-3 would be your simplified equation

Answer:

B. r = A-p/pt

Step-by-step explanation:

We can rearrange the equation to make [tex]r[/tex] the subject of the equation:

[tex]A=p+prt[/tex]

[tex]A-p = p+prt-p[/tex]

[tex]A-p = prt[/tex]

[tex]\frac{A-p}{pt} = \frac{prt}{pt}[/tex]

[tex]r = \frac{A-p}{pt}[/tex]

∴ Option B is correct

Answer:

(3y - 1)(y - √3)(y + √3)

Step-by-step explanation:

Factor by grouping.

3y³ - y² - 9y + 3

= (3y³ - y²) - (9y - 3)

= y²(3y - 1) - 3(3y - 1)

= (3y - 1)(y² - 3)

= (3y - 1)(y - √3)(y + √3)

Answer: 120 degrees

Step-by-step explanation: a circle always has a total of 360 degrees

Answer:

D

Step-by-step explanation:

The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).

<2 + 40 + 40 = 180            Combine the left

<2 + 80 = 180                    Subtract 80 from both sides

<2 = 180 - 80

<2 = 100 degrees.

That's not the answer. We have to solve for x

<2 = x + 106

100 = x + 106       Subtract 106 from both sides

100 - 106 = x

x = - 6

Answer:

180m

Step-by-step explanation:

Let L = length of field,

W = width of field,

A = field area = 2000 m^2

Lenght = Width + 10m

Let Lenght= x

Width=y

A = X ×Y = (Y + 10)Y= 2000

Y^2 + 10Y- 2000 = 0

Solving using Quadratic eqn with plot

Y= 40 or -50 but we go for the positive root

Width=40m

Length= 40m +10m

= 50m

Perimeter= 2(l+w)

=2(50+40)

180m

Hence, the perimeter is 180 m

Answer: [tex]a_{10}[/tex] = -33

Step-by-step explanation:

-6, -9, -12, -15

The common difference is -3

d = common difference

Arithmetic sequence formula:

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1) d

[tex]a_{10}[/tex] = -6 + (10 - 1) -3

[tex]a_{10}[/tex] = -6 + 9 × -3

[tex]a_{10}[/tex] = -6 - 27

[tex]a_{10}[/tex] = -33

Answer:

The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.

Step-by-step explanation:

Given that:  

65 miles in 2.7 gallons

We have to find the unit rate.

Unit rate is a rate to compare quantities in which one quantity is 1.

Unit rate = [tex]\frac{65}{2.7}[/tex]

Unit rate = 24.07 miles per gallon.

Hence,

The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.

Answer:

x = 20 degrees

Step-by-step explanation:

From the diagram shown, we are to find the value of

Since the adjacent side of the parallelogram on top are equal, hence their opposite angles are also equal

The third angle in the triangle below will be 180 - 60 = 120

Sum of angle in the triangle is 180 degrees, hence;

x + 2x + 120 = 180

3x = 180-120

3x = 60

x = 60/3

x = 20 degrees

Hence the value of x in the diagram is 20 degrees

Answer:

perimeter of the larger rectangle would be 30, since the ratio of the larger rectangle is double the ratio of the small rectangle, you would have to double the peri. of the small rect. to get the peri. of the large rect.

Answer:

We conclude that the rule for the table in terms of x and y is:

Step-by-step explanation:

The table indicates that there is constant change in the x and y values, meaning the table represents the linear function the graph of which would be a straight line.

We know the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept.

Taking two points

Finding the slope between (-2, -4) and (-1, -1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-4\right)}{-1-\left(-2\right)}[/tex]

[tex]m=3[/tex]

We know that the y-intercept can be determined by setting x = 0 and finding the corresponding y-value.

Taking another point (0, 2) from the table.

It means at x = 0, y = 2.

Thus, the y-intercept b = 2

Using the slope-intercept form of the linear line function

y = mx+b

substituting m = 3 and b = 2

y = 3x+2

Therefore, we conclude that the rule for the table in terms of x and y is:

8) i do not know how to read this...

Answer:

The question is written kinda bad, so i take the next two assumptions:

The original line is:

y = 5*x + 23

And we want to find a perpendicular line that passes through the point (-40, 2012)

Suppose that we have a linear equation:

y = a*x + b

A perpendicular line to this one, will have a slope equal to -(1/a)

Then a random perpendicular line to the one above, is:

y = -(1/a)*x + c

In this case, we start with the line:

y = 5*x + 23

Then the family of perpendicular lines to this one, will be like:

y = (-1/5)*x + c

Where c can be any real number.

Now, we also want this line to pass through (-40, 2012)

This means that when x = -40, the value of y must be 2012

We could replace these values in our equation above and solve it for c.

2012 = -(1/5)*(-40) + c

2012 = 40/5 + c

2012 = 8 + c

2012 - 8 = c = 2004

Then the equation is:

y = -(1/5)*x + 2004.
