Answer:

y = 3x + 15

so

4x - 3y = 25

4x - 3x + 15 = 25

x = 25 - 15

x = 10

Answer:

x=-14,y=-27

Step-by-step explanation:

Given equations:

y=3x+15

4x-3y=25

We can substitute the first equation into the second:

4x-3y=25 (given)

4x-3(3x+15)=25 (replaced y for 3x+15)

4x-9x-45=25

-5x=70

x=-14

We can solve for y by using substitution:

y=3x+15 (given)

=3(-14)+15

=-27

∴ x=-14,y=-27

Hope this helps :)

What is the surface area of the regular pyramid
Ugo [173]

Answer:

The answer is 144.

Step-by-step explanation:

Cause, 6 x 6 for the square is 36. For the triangle, 9 x 6 is 54, and 54 divided by 2 is 27. 27 x 4 is equal to 108. Now, we just add 108 and 36 to make 144.

Need help please assist me find the area of a regular hexagon
garri49 [273]

Answer:

The area of the regular hexagon is 166.3\ units^{2}

Step-by-step explanation:

we know that

The area of a regular hexagon can be divided into 6 equilateral triangles

so

step 1

Find the area of one equilateral triangle

A=\frac{1}{2}(b)(h)

we have

b=r=8\ units

h=4\sqrt{3}\ units ----> is the apothem

substitute

A=\frac{1}{2}(8)(4\sqrt{3})

A=16\sqrt{3}\ units^{2}

step 2

Find the area of 6 equilateral triangles

A=(6)16\sqrt{3}=96\sqrt{3}=166.3\ units^{2}

The graph of the parent function f(x) = x3 is translated such that the resulting graph can be represented by the function g(x) =
kirill115 [55]

Answer:

Translated 1 to the right and up one

Step-by-step explanation:

When the number is inside the parenthesis with x, that value represents a horizontal shift. because the original equation is (x-h), the opposite sign of the x value must be taken. so in this case the x value would be +1 because that is the opposite of -1, which means the function is being moved one to the right. when the number is being added to the outiside of the parenthesis, then you take that value for the vertical translations of the graph. because the original equation is (x-h)+k, then in this case there would be a vertical shift up by 1

Write down the 3rd term in the sequence given by: T(n) = n2 + n
Sergio [31]
The solution for the problem is:
I will first get the first five terms so that I could easily locate the third term of this problem:So, substituting the values:
T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25
So the third terms is T(3) = 3^2 = 9
