Answer:

It is a rhombus.

Step-by-step explanation:

We have the four equations:

3x - y = -4

3y - x = 4

3y = x + 12

y = 3*x - 4

First, we need to write all of them in slope-intercept form, so they are easier to read.

We get:

y = 3*x+ 4

y =  (1/3)*x + 4/3

y = (1/3)*x + 12/3

y = 3*x - 4

First, we can see that:

y = 3*x+ 4 and y = 3*x - 4

are parallel lines, because they have the same slope.

y =  (1/3)*x + 4/3 and y = (1/3)*x + 12/3  also are parallel lines, because they have the same slope.

Then this is a parallelogram.

Now, here we have two slopes, 3 and 1/3.

Remember that for a line y = a*x + b

A perpendicular line would be written as:

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

From this we can see that there are no perpendicular lines in our set of lines.

Then this can not be a square nor a rectangle.

It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.

Then this can only be a rhombus.

Below you can see the graph of the four lines to see which quadrilateral they form.

Step-by-step explanation:

Answer:

Given:

A car travels 2 1/3 miles in 3 1/2 minutes.

We need to find the distance travelled in ​25 minutes, in 1 hour.

So, 2 1/3= 7/3 and 3 1/2 = 7/2

Let's convert them into decimals by dividing them completely.

So, we will get 2.33 miles and 3.5 minutes.

So now we have that 2.33 miles are covered in 3.5 minutes.

Now we need to know the distance covered in 1 minute.

So, 2.33/3.5=0.67

So now we have in one minute 0.67 miles are covered.

Now distance covered in 25 minutes will be:

0.67*25 = 16.75 miles

Now distance covered in one hour:

1 hour = 60 minutes.

So, 0.67*60 = 40.2 miles

So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.

Answer:

- [tex]\frac{15}{4}[/tex]

Step-by-step explanation:

Given

3x - 8y = 39 ← substitute x = 3 into the equation

3(3) - 8y = 39

9 - 8y = 39 ( subtract 9 from both sides )

- 8y = 30 ( divide both sides by - 8 )

y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

Answer:

-3 and 1

Step-by-step explanation:

The zeros of the given function are -3 and 1.

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

Answer:

g' (×)=f

Step-by-step explanation:

g (×)=f×-7

g' (×)= d÷d× (f×-7)

g' (×)=d÷d×(f×)-d÷d×(7)

g'(×)=f-d÷d×(7)

Answer:

13cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 12cm

b = 5cm

c = hypotenuse

[tex]12^{2} +5^{2} =c^{2}[/tex]

[tex]144+25=c^{2}[/tex]

[tex]\sqrt{169} =c[/tex]

13 = c

Answer:

Step-by-step explanation:

a^2+b^2=c^2

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.
