Answer:

when we take the square root of 500 we get number with decimal value so its not a perfect square

Step-by-step explanation:

x^2=500

x=square root of 500

QUICK 100 POINTS AND BRAINLIST ANSWER QUICK

irina1246 [14]

Answer:

Part A:

The y-intercept is $1,500

The x-intercept is 20 days

Part B:

Equation of the line in point-slope form is y - 1350 = -75×(x - 2)

Equation of the line in slope-intercept form is y = -75·x + 1500

Equation of the line in standard form is y + 75·x = 1500

Part C:

f(x) = -75·x + 1500

Part D:

$1,125

Step-by-step explanation:

The information given are;

x, g(x)

0, $1,500

2, $1,350

4, $1,200

The equation of a straight line relation between the x, and y, coordinates in slope and intercept form is y = m·x + c

Where;

m = The slope ,

c = The y-intercept

From the data, we have two points, (x₁, y₁), (x₂, y₂) given as (0, 1,500), (2, 1350);

The y-intercept = y at x = 0 = 1,500

y = -75·x + 1500

x = 1500/75 = 20

Part B:

The equation in point-slope form is y - y₁ = m×(x - x₁)

Which gives;

Equation of the line in point-slope form is y - 1350 = -75×(x - 2)

Equation of the line in slope-intercept form is y = -75·x + 1500

Equation of the line in standard form is y + 75·x = 1500

Part C:

The equation of the line using function notation is f(x) = -75·x + 1500

Part D:

The balance in the bank after 5 days is f(5) = -75 × 5 + 1500 = $1,125

maria bought 1224 cm of ribbon for her art picture at $0.75/m. how much did she pay for ribbon, to the nearest cent?

k0ka [10]

Data:
Tape size = 1224 cm → 12.24 m
Price per size = $0.75/m

Solving: Rule of three (directly proportional)

$ (price) __ (Size)
0.75 ----------- 1 m
y --------------- 12.24 m

Multiply cross

 $y = 0.75*12.24$
$\boxed{\boxed{y = \$\:9.18}}\end{array}}\qquad\quad\checkmark$

Answer:
She paid for the tape $ 9.18
