Answer:

y = -4/5x - 5

Step-by-step explanation:

4x + 5y = 45

we need to write it in slope intercept form, so:

5y = -4x + 45

y = -4/5x + 45/5

y = -4/5x + 9

The line is parallel so the slope will be -4/5x, point ( -5 -1 )

y = mx + b

-1 = -4/5(-5)+b

-1 = 4 + b

-1 - 4 = b

-5 = b

y = -4/5x - 5

Interest from first account is :

$I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918$

Interest form second account is :

$I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 = \$25.959$

So, total interest is :

$I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877$

Therefore, total interest is $77.877 .

Solve 4x + 1 = 3 – 2x

romanna [79]

Answer:

x = 1/3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

4x + 1 = 3 - 2x

Step 2: Solve for x

Add 2x on both sides: 6x + 1 = 3
Subtract 1 on both sides: 6x = 2
Divide 6 on both sides: x = 1/3

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 4(1/3) + 1 = 3 - 2(1/3)
Multiply: 4/3 + 1 = 3 - 2/3
Add/Subtract: 7/3 = 7/3

Here we see that 7/3 does indeed equal 7/3.

∴ x = 1/3 is a solution of the equation.

Answer:

(0, 6)

explanation:

original coordinates of C: (5, -6)

if reflected over x-axis, then use the formula: (x,y) → (x, -y)

new coordinates: (5, 6)

then if translated -5 horizontally, there will be change in x axis

new coordinates: (5-5, 6) → (0, 6)
