Answer:

A pair of linear equations which has a unique solution x = 2, y = –3 is

a) x – 4y –14 = 0

5x – y – 13 = 0

b) 2x – y = 1

3x + 2y = 0

c) x + y = –1

2x – 3y = –5

d) 2x + 5y = –11

4x + 10y = –22

HELP ASAP solve the equation using the properties of equality. 89= -5d+9

sergey [27]

Answer:

d = -16

Step-by-step explanation:

Step 1: Write equation

89 = -5d + 9

Step 2: Solve for d

Subtract 9 on both sides: 80 = -5d

Divide both sides by -5: -16 = d

Step 3: Check

Plug in x to verify if it's a solution.

89 = -5(-16) + 9

89 = 80 + 9

89 = 89

What is the amplitude, period, and phase shift of f(x) = −3 cos(4x + π) + 6?

hammer [34]

This is in the form of $\sf acos(bx-c)+d$ .

Amplitude is equal to $\sf |a|$
Period is equal to $\sf\dfrac{2\pi}{|b|}$
Phase Shift is equal to $\sf\dfrac{c}{b}$

Plug in the values:

Amplitude:
$\sf |a|\rightarrow |-3|\rightarrow\boxed{\sf 3}$

Period:
$\sf\dfrac{2\pi}{|4|}\rightarrow\dfrac{2\pi}{4}\rightarrow\boxed{\sf\dfrac{\pi}{2}}$

Phase Shift:
$\sf\dfrac{c}{b}\rightarrow\boxed{\sf -\dfrac{\pi}{4}}$
