Let m = slope

Use the point-slope formula.

y - y1 = m(x - x1)

Let y1 = 3

Let x1 = 2

y - 3 = 1(x - 2)

Solve for y.

y - 3 = x - 2

y = x - 2 + 3

y = x + 1

Done!

"slope-intercept form" is y = mx + b.

We have a point on this line and we also have the slope of the line. Thus:

3 = 1(2) + b, so b =1 and the equation is y = x + 1.

The number $75$ is decreased by $40\%$, then the result is again decreased by $40\%$. What is the final result?

stich3 [128]

To get 75 decreased by 40% you subtract 40% from 100%.
100 - 40 = 60

So to get 60% of 75 you multiply .60 by 75.
.60 x 75 = 45

You have $45 now, but you have to decrease it by 40% again. You do the same process, so we need to multiply .60 by 45.
.60 x 45 = 27

So, the final result is $27.

Peter inherits 15.000 dollars and place money with a bank. The interest rate are 3 percent. How many money will he get after 1ye

NeTakaya

The simplest form of an interest equation is A = P(1+rt)

where A = the total amount of money at the end, P = the principal (or amount of money you started with), r = the rate in percent, and t = the time in years.

In this case, P = 15000, r = 0.03 (because 3% in decimal form is 0.03), and t = 1:

$A=P(1+rt)\\A=15000(1+0.03*1)\\A=15000(1+0.03)\\A=15000(1.03)\\A=15450$

So, after 1 year he will get $15450 back, making him $450 more.

The graph of a square root function has a domain of (0, infinity) and range of [1, infinty). In two or more complete sentences,

KIM [24]

We know that Range of a function is the values that a function can take in its domain The range interval of a function is between the minimum value and the maximum value that the function can take so in this problem The range of the function is the interval-------> [1, ∞)

That means The minimum value of the function in the domain is The maximum value of the function in the domain is infinite
