Answer:

y = 5

Step-by-step explanation:

first you subtract 5y from itself and from 7y

then you'll get: 2y + 2 < 12

then subtract the 2 from itself and from the 12

that will give you: 2y < 10

then just divide the 2 from itself and that eliminates the 2 but keeps the y, and divide the 10 by the 2

that'll give you y = 5

QUESTION 1a.

We want to add

( - 2 {x}^{2}  - 4x + 13) + (12 {x}^{2}  + 2x - 25)

We group similar terms to get

- 2 {x}^{2}  + 12 {x}^{2}- 4x + 2x   - 25 + 13

Simplify:

- 10{x}^{2} - 2x  -12

QUESTION 1b.

The given function is:

(7x^2+4x-26)-(-7x^2-3x+15)

Expand the parenthesis to obtain,

7x^2+4x-26 + 7x^2 + 3x - 15

Group similar terms,

7x^2+7 {x}^{2}  + 4x + 3x-26  - 15

Simplify:

14{x}^{2}  + 7x-41

QUESTION 2

The given function is

f(n)=n^2-6n-16

The zeros of this function is given by;

n^2-6n-16 = 0

Split the middle term.

n^2-8n + 2n-16 = 0

Factor;

n(n - 8) + 2(n - 8) = 0

(n - 8)(n + 2) = 0

n - 8 = 0 \: or \: n + 2 = 0

n  = 8 \: or \: n =  - 2

Find the value of x on this triangle
blondinia [14]
Look at the picture.

ΔABD and ΔBCD are similar, therefore:

\dfrac{y}{5}=\dfrac{11}{y}\ \ \ |\cross\ multiply\\\\y^2=55\to y=\sqrt{55}

Use Pythagorean theorem:

x^2=5^2+(\sqrt{55})^2\\\\x^2=25+55\\\\x^2=80\to x=\sqrt{80}\\\\x=\sqrt{16\cdot5}\\\\x=\sqrt{16}\cdot\sqrt5\\\\\boxed{x=4\sqrt5}
