elimination of x:

-6x +5y = 1

6x + 4y = -10

___________+

9y = -9

y = -9/9 = -1

elimination of y:

-24x +20y = 4

30x + 20y = -50

_____________-

-54x = 54

x = 54/-54 = -1

{ -1, -1}

\huge{ \mathcal{  \underline{ Answer }\:  \:  ✓ }}

The given equations are :

\longrightarrow - 6x + 5y = 1

\longrightarrow6x + 4y =  - 10

let's add the equations

\longrightarrow\small{ - 6x + 5y +6x + 4y =  1  + ( - 10)}

\longrightarrow9y =  - 9

\longrightarrow y =  - 1

now, let's plug the value of y in first equation :

\longrightarrow - 6x + (5 \times  - 1) = 1

\longrightarrow - 6x  - 5 = 1

\longrightarrow - 6x = 6

\longrightarrow x =  - 1

What are the zeros of the function below? Check all that apply.
PolarNik [594]

Answer:

A, B, D, F

Step-by-step explanation:

Given

f(x) = (x + 3)(x - 1)(x - 2)(x + 2)

To find the zeros let f(x) = 0, that is

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

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3 → B

x - 1 = 0 ⇒ x = 1 → F

x - 2 = 0 ⇒ x = 2 → D

x + 2 = 0 ⇒ x = - 2 → A

what is the length of the diagonal of a non-regulation tennis court with length 20 feet and width 15 feet?
Semmy [17]

Answer:

25 feet

Step-by-step explanation:

Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse.  So....

H² = A² + B²

H² = 20² + 15² = 400 + 225 = 625

H = 25 feet.

No. of pages typed by the student in 1 hour= \frac{2/3}{1/5}

= \frac{2}{3}×5
