What is the solution to the system of equations? y = 2x – 3.5 x – 2y = –14 (–7, 3.5) (3.5, –7) (7, 10.5) (10.5, 7)

y = 2x-3.5 ----->1

x-2y=-14. ----->2

1 into 2

x-2(2x-3.5)=-14

x-4x+7=-14

-3x=-14-7

-3x=-21

x=-21/-3

x=7 --- -->3

3 into 1

y = 2x-3.5

y=2(7)-3.5

y=10.5

Answer:

The rate is 15 minutes per meter.

Step-by-step explanation:

It takes 9 minutes to fill a depth of  meters.

Filling   meters take 9 minutes time.

Filling 3 meters of the aquarium takes  = 45 minutes time (Multiplying by 5 both the numbers).

In order to fill 1 meter of the aquarium it will take  minutes (Dividing by 3 both the numerical values).

Answer:

<h2>Function 1 has the least minimum value and its coordinates are (2. - 7).</h2>

Step-by-step explanation:

The first function is

f(x)=2x^{2} -8x+1

The second function is

x   g(x)

-2    2

-1    -3

0     2

1     17

The vertex has coordinates of V(h,k), where h=-\frac{b}{2a} and k=f(h).

Let's find the vertex for the first function where a=2 and b=-8.

h=-\frac{-8}{2(2)}=2

k=f(2)=2(2)^{2} -8(2)+1=8-16+1=-8+1=-7

Therefore, the vertex of the first function is at (2,-7).

Now, the minimum value of the second function can be deducted from its table, which is (-1,-3).

Therefore, f(x) has -7 as minimum value and g(x) has -3 as minimum vale.

So, the right answer is B, because -7 is less than -3.

What is the answer to this?
OlgaM077 [116]

Answer:

Step-by-step explanation:

Note how this drawing  is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.

Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30.  Due to the symmetry shown, line CD has the same length:  30.
