Answer:

Step-by-step explanation:

1) Solve for the slope(m):

(y2-y1) / (x2-x1)

pick any

(-3 - (-5) )/ (1 - 0)

(-3 + 5) / (1 - 0)

2/1 = 2

2) b(intercept) value is found when x = 0:

x = 0, y = -5,

b = y

b = -5

3) Plug it in:

y = mx + b

y = 2x - 5

4) when the value is 5, x = 5:

y = 2x - 5

y = 2(5) - 5

y = 10 -5 = 5

What is one factor of 2x^2-32y^2

serg [7]

Here you have two terms connected by the "subtraction" symbol.

The two coefficients are 2 and 32, and one factor common to both of these is 2. Thus, 2x^2-32y^2 = 2(x^2-16y^2).

You could stop here. But it'd make more sense to continue, since x^2-16y^2 is easy to factor:

The three factors of 2x^2-32y^2 are 2, x-4 and x+4

PLEASE HELP

Answer:

$593.26

Step-by-step explanation:

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = $\frac{75}{100} *2500 =$ $1875

for 2nd year = $\frac{75}{100} *1875 =$ $1406.25

for 3rd year = $\frac{75}{100} *1406.25 =$ $1054.7

for 4th year = $\frac{75}{100} *1054.7 =$ $791.01

for 5th year = $\frac{75}{100} *791.01 =$ $593.25

Or we can use the following formula to find its resale value after 5 years:

$2500*(0.75)^5 =$ $593.26

A spinner is divided into 4 sections. The spinner is spun 100 times. The probability distribution shows the results.

Vitek1552 [10]

P(1≤x≤3) defined the probability that the result is between 1 and 3, included. You can answer this question in two ways:

1. Sum the probabilities of good events:

From the graph, we have

$P(x=1) = 0.32,\quad P(x=2) = 0.24,\quad P(x=3) = 0.28$

So,

$P(1\leq x \leq 3) = 0.32+0.24+0.28 = 0.84$

2. Use complementary probabilities

Asking that the result is 1, 2 or 3 is the same as asking that the result is not 4. The probability that the result is 4 is 0.16, so the probability that the result is not 4 will be

$P(x\neq 4) = 1-P(x=4) = 1-0.16=0.84$

The result is obviously the same.
