Answer:

C: y = -3x +3

Step-by-step explanation:

Lines that are parallel have the same slope have so the slope of the line in -3, now we have to find the y-intercept, we can do this by substituting -2 for x and 9 for y and solve for b

9 = -3(-2) +b

9 = 6 + b

b = 3

So the line that is parallel to y = -3x -8 and goers through the point (-2,9) is y = -3x + 3 or answer C

Answer:

y = -3x + 3

Step-by-step explanation:

Since the line is parallel, it has the same slope. Plug the point you have into the equation y - y1 = slope (x -x1) to get your answer, which should be y = -3x +3

Write the exact value of the side length of each square. If the value is not a whole number, estimate the length.

Savatey [412]

Given:

The area of the squares are given.

To find:

The exact side length or estimate side length of the square.

Solution:

We know that, the area of a square is

$A=a^2$

Where, a is the side length of the square.

$a=\sqrt{A}$

Area of the square is 100 square units. So, the side length is:

$a=\sqrt{100}$

$a=10$

Therefore, the side length is 10 units.

Area of the square is 95 square units. So, the side length is:

$a=\sqrt{95}$

It is not exact. We know that $\sqrt{81}$ .

Therefore, the side length is between 9 and 10.

Area of the square is 36 square units. So, the side length is:

$a=\sqrt{36}$

$a=6$

Therefore, the side length is 6 units.

Area of the square is 30 square units. So, the side length is:

$a=\sqrt{30}$

It is not exact. We know that $\sqrt{25}$ .

Therefore, the side length is between 5 and 6.

A quadratic equation is shown below:

lys-0071 [83]

16x^2 − 8x + 1 = 0

Part A:
b^2 - 4ac for ax^2 + bx + c

16x^2 − 8x + 1 = 0
so in this case,
a = 16, b = -8, c = 1

b^2 - 4ac
=(-8)^2 - (4 * 16* 1)
= 64 - 64
= 0
because it's equal 0, answer is one solution

Part B:

4x^2 − 8x − 45 = 0
solve the equation by factoring 
= (2x - 9)(2x + 5)

set (2x - 9)(2x + 5) equal to 0 to solve for x
so
(2x - 9)(2x + 5) = 0
2x - 9 = 0
x = 9/2
x = 4.5

2x + 5 = 0
x = -5/2
x = -2.5
answer
x = -2.5 or x = 4.5

Hope it helps
