Answer:

y = -2x - 5

Step-by-step explanation:

<u>1) Find the slope of the line.</u>

The slope of the original line is the same as the slope of the parallel line.

Slope formula:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

In this case you can choose any 2 set of points on the table.

$m = \frac{4 - 2}{-3 - (-2)}$ = $\frac{4 - 2}{-3 + 2}$ = $\frac{2}{-1}$ = -2

So the slope of the line is -2

<u>2) Use the point-slope formula to find the equation of the line.</u>

Point-slope formula:

$y - y_{1} = m(x - x_{1})$

Now plug in the point (0, -5) and the slope -2 into the equation.

y - (-5) = -2(x - 0)

y + 5 = -2(x - 0)

To solve the equation first apply the distributive property.

y + 5 = -2x + 0

y + 5 = -2x

Next, subtract 5 from sides.

y = -2x - 5

You know have your equation in point-slope form!

three apples weigh about a pound. about how much would one apple cost ? (round to the nearest cent) (apples are $0.50 per pound)

BARSIC [14]

Answer:

$0.17

Step-by-step explanation:

If apples are $0.50 per pound and there are 3 apples in a pound, you can do $0.50 divided by 3 to find the cost per apple.

0.5 / 3 = 0.16666 which rounds to $0.17

YO please help actually been waiting for an hour and a half cuz so many trolls lol. <3 giivng brainliest, and ty in advance g

Hello!

For this problem we are given that quadrilateral ABCD is congruent to quadrilateral GJIH, meaning that all sides and angle measures will be equivalent to its corresponding side.

This means that to find $x$ , we can look at quadrilateral GJIH's corresponding side to quadrilateral ABCD's side AD, which is side GH, which has a value of 9.

This means that 9 should also be the side length of side AD, which we're given a value of $x/3$ .

$x/3=9$

Solve.

$x=27$

Hope this helps!

Karen has 9 feet of lace for her tablecloth. She used 3 feet of lace.

RideAnS [48]

First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards

What are the real and complex solutions of the polynomial equation? x^3-8=0. with imaginary numbers

seraphim [82]

Answer:

Solutions are 2, -1 + 0.5 sqrt10 i and -1 - 0.5 sqrt10 i

or 2, -1 + 1.58 i and -1 - 1.58i

(where the last 2 are equal to nearest hundredth).

Step-by-step explanation:

The real solution is x = 2:-

x^3 - 8 = 0

x^3 = 8

x = cube root of 8 = 2

Note that a cubic equation must have a total of 3 roots ( real and complex in this case). We can find the 2 complex roots by using the following identity:-

a^3 - b^3 = (a - b)(a^2 + ab + b^2).

Here a = x and b = 2 so we have

(x - 2)(x^2 + 2x + 4) = 0

To find the complex roots we solve x^2 + 2x + 4 = 0:-

Using the quadratic formula x = [-2 +/- sqrt(2^2 - 4*1*4)] / 2

= -1 +/- (sqrt( -10)) / 2

= -1 + 0.5 sqrt10 i and -1 - 0.5 sqrt10 i
