Answer:

A right triangle needs to have all the sides of the same length. Since this obviously does not, it is not a right triangle. Infact, this is a scalene triangle because all of its sides are unequal.

Answer:

y = x - 7

Step-by-step explanation:

Parallel lines have the same gradient in this case 1 is the gradient.

Using the point (8,1) we can form our own equation.

1 will be y, 1 will be m, 8 will be x

All we have to do is find C in order to form the equation y=mx+c

1 = 1(8) + c

1 = 8 + c

C = - 7

Therefore;

y = x - 7

28.5 seconds

cuz 114 ÷ 4 = 28.5 = 28.5 × 4 = 28.5

hope it will help u

Answer:

Step-by-step explanation:

5 m = 4 second

1 m = 4/5 second

1 m = 0.8 second

∴ 114 m = 114 x 0.8

           = 91.2 seconds.

Brainliest would be really appreciated if it helped :)

Answer:

Answer is: two electrons.

n - principal quantum number, indicating relative overall energy of each orbital, n=1,2,3,...

l - angular momentum quantum number, shape of the orbital, l = 0,1,...,n−1.      

l =1 for the p orbitals.

ml - magnetic quantum number, ml = 0,±1,...,±l.

This is 2px orbital, in every orbital there is two electrons with different spin.

[tex]49x - 7[/tex]

[tex]7(7x - 1)[/tex]

The solution is: Option C is correct. Factor using the GCF: 49x - 7 is

7(7x-1).

Here, we have,

given that,

we have to factor using the GCF: 49x - 7.

we know that,

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted {\displaystyle \gcd}.

so, we have,

49x - 7

now, we know,

7 * 7 = 49

and, 7 * 1 = 7

so, we get, the GCF of 49 and 7 is 7.

so, we have,

Factor out 7 from the expression and remaining will be.

7(7x-1)

i.e. 49x - 7 = 7(7x-1)

Hence, Option C is correct. Factor using the GCF: 49x - 7 is 7(7x-1).

Answer:

Slope = 3/5

Step-by-step explanation:

Slope = (change in y) / (change in x)

          = (4 - 10)/(-4 -6)

          = -6/-10

          =  3/5

Answer:

The answer is not given in the options.

Step-by-step explanation:

2x = 13

or, 2x/2 = 13/2  (multiplying with (1/2) in both sides)

or, x = 13/2

or, x = 6.5

Answer:

it depends on how big the rectangle is though...

Step-by-step explanation:

Answer:

6x + 10

Step-by-step explanation:

Given,

Length ( l ) = 3x

Breadth ( b ) = 5

To find : Perimeter of the rectangle = ?

Formula : -

Perimeter of the rectangle = 2 ( l + b )

Perimeter of the rectangle

= 2 ( 3x + 5 )

= 2 ( 3x ) + 2 ( 5 )

= 6x + 10

Answer:

Step-by-step explanation:

you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.

so 70 + 40 + 20 + 60 + 20 + 40 i believe.

this all equals 250.

ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.

Answer:

y = -3x + 4

Step-by-step explanation:

To find the slope, use rise over run with two points. The first point (0,4) to the second point (-2,-2) is 6 units down and 2 units to the right, so you can set up a fraction to solve for the slope:

-6/2 = -3

To find the y-intercept,find the point where the x-value is 0. That point is (0,4),so the y-intercept is 4.

mx represents the slope, so mx is -3x and b is the y-intercept, so that value is 4.

Answer:

y = -3x + 4

Step-by-step explanation:

m = the slope (rise/run)

b = y-intercept

we can see that the rise is 6 (based on the two points) and the run is 2 (based on the labeled points)

- that means that m = 6/2 or m = 3

y = 0  when x = 4, so the y-intercept is 4, or b = 4

put it together!

y = 3x +b

BUT WAIT!!

- the line is decreasing which means that your equation should be negative, so put a negative symbol before 3x.

   - why? the rise is decreasing!

final equation --------> y = -3x + 4

Answer:

80 miles

Step-by-step explanation:

The map scale compares the  distance between two points on the map with the corresponding distance on the ground.

That is,

[tex]\boxed{\mathfrak{map\:scale=\frac{distance\:on\:map}{distance\:on\:ground} }}[/tex]

The formula makes it pretty easy to solve!

Substituting these values in the above mentioned formula:

[tex]\implies \mathsf{\frac{1 \:inch}{20\:miles} =\frac{4\:inches}{x\:miles} }[/tex]

cross multiplying:

[tex]\implies\mathsf{x=4 \times 20}[/tex]

[tex]\implies \mathsf{x=80}[/tex]

That makes the actual distance 80 miles!

You can also use simple unitary method here:

1 inch on the map = 20 miles on the ground

∴ 4 inches on the map = 4 × 20 miles on the ground

= 80 miles on the ground

Answer:

Step-by-step explanation:

Find the zeroes of the function f ( x ) = x 2 + 12 x + 32

First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )

Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )

Set each factor equal to zero and the answer is x = − 8 and x = − 4 .
