LOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1. f(x)=

Brut [27]

Answer:

The euation of the linear function is:

y = -1

Step-by-step explanation:

As the function has the values

at x = 5, f(5) = -1

at x = 0, f(0) = -1

Thus, the two points are:

(5, -1)

(0, -1)

Finding the slope between (5, -1) and (0, -1)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)$

$m=\frac{-1-\left(-1\right)}{0-5}$

$m=0$

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.

so at x = 0, y = -1

Thus, the y-intercept 'b' = -1

Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation

y = mx+b

y = 0x + -1

y = -1

Therefore, the euation of the linear function is:

y = -1

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

*Note:

The distance formula is derived from the Pythagorean Theorem.

Step 1: Define

Identify

Point (5, 10)

Point (10, 12)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(10 - 5)^2 + (12 -10)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{5^2 + 2^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{25 + 4}$
[√Radical] Add: $\displaystyle d = \sqrt{29}$

Identify an equation that models the situation and find its solution. Kane planned to build a 53-centimeter-tall model of a buil

alex41 [277]

Answer:

The increment in the model is 106cm

Step-by-step explanation:

Given

$Initial\ Height = 53cm$

$Final\ Height = 159cm$

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

$Increment = Final\ Height - Initial\ Height$

$Increment = 159cm - 53cm$

$Increment = 106cm$

Hence, the increment in the model is 106cm

Call T the price of the T-shirts and P de price of the jeans

Initially (without discount)
2T + P = 40

One month later (half prices)
2 (T/2) + 5(P/2) = 60
T +5P/2 = 60

To solve the system of equations multiply the second equation by 2 and substract it from the first equation

   2 T + 5P = 120
- (2 T +   P = 40 )
________________

   4P = 80

P = 80/4
P = 20

From 2T + P = 40

T = (40 - P) / 2 = (40 -20) / 2 = 20/2 = 10.

The price of a T-shirt is $10 and the price of a pair of jeans is $20.

Answer:

A- control group

Since group A is tested under normal condition, it is the control group. Control group is separated from other groups so that the independent variable being tested cannot influence the result.
