A line intersects the points (-23, -17) and (-13, -7). Find the slope of the line.

dolphi86 [110]

The slope of a line through points $A(x_1, y_1)$ and $B(x_2, y_2)$ is :

$\displaystyle{ \frac{y_2-y_1}{x_2-x_1}$

or

$\displaystyle{ \frac{y_1-y_2}{x_1-x_2}$ ,

it is the same thing, BUT it it always y's over x's and always in the same order of 1 and 2:

don't write: $\displaystyle{ \frac{y_1-y_2}{x_2-x_1}$

--------------------------------------------------------------------------------------------------

The slope of the line through the points <span>(-23, -17) and (-13, -7) is :

</span> $\displaystyle{ \frac{-17-(-7)}{-23-(-13)}= \frac{-17+7}{-23+13}= \frac{-10}{-10}=1$
<span>

Answer: 1</span>

The image shows a geometric representation of the function f(x) = x2 – 2x – 6 written in standard form. An algebra tile configur

Over [174]

Answer:

$f(x)=(x-1)^2-7$

Step-by-step explanation:

Standard form:

$f(x)=x^2-2x-6$

Vertex form:

$y=(x-h)^2+k$

(h, k) is the vertex

x is the coordinate of the vertex

To find x use the formula:

$x=\frac{-h}{2a}$

$f(x)=x^2-2x-6$

a=1

b=-2

c=-6

Substitute:

$x=\frac{-(-2)}{2(1)}=1$

Substitute x in equation:

$f(x)=1^2-2(1)-6\\f(x)=1-2-6\\f(x)=-7$

h=1

k=-7

Substitute h, and k into the vertex formula:

$f(x)=(x-1)^2-7$

If one tosses a coin three times, write dow nthe possible observed number of heads and their probabilities

seropon [69]

You need to find the probability of Heads, Heads, Heads in 3 tosses;

P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one
P(HHH)=1/8

Therefore, the probability of flipping 3 heads on a fair coin is 1/8

Hope I helped :)

If the cost of a dress is $75.00 and

11Alexandr11 [23.1K]

Answer:

80%

Step-by-step explanation:

Original price =$75.00

Sale price =$60.00

The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.

So % discount = $60.00/$75.00 x 100%

0.8 x 100%

80%

Janelle got the dress on a discount of 80%.

This is so because she got the dress for a price less than the original price
