You could use the equation y=mx+b

Find the slope of the two coordinates. I would personally suggest using stack and subtract:

(0,2) 2-5 -3 3
(2,5) -------= ------= -----
0-2 -2 2

We have the slope but we need to find the y-intercept.

y=3
--x+b
2

Plug one of the coordinates in the constructed equation above:

2=3
-- (0)+b
2

2=0+b
-0=-0
------------
b=2

We found the slope and y-intercept. Now we have our complete equation. The equation is:

y=3
--x+2
2


Have a blessed day!

Using translation concepts, it is found that the transformations to create function d are given as follows:

  • Horizontal shift right 1 unit.
  • Vertical shift up 5 units.
  • Frequency multiplied by 2.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent cosine function is given by:

f(x) = cos(x).

The translated function is given by:

d(x) = cos(2x - 1) + 5.

Which means that:

  • 1 was subtracted in the domain, hence the was a horizontal shift right 1 unit.
  • 5 was added in the range, hence there was a vertical shift up 5 units.
  • There was a multiplication by 2 in the domain, hence the frequency is multiplied by 2.

the first few steps in solving the quadratic equation 5x2 27x = 14 − 13x by completing the square are shown. 5x2 27x = 14 − 13x
Artist 52 [7]
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since  80 =  5 · 16
5 ( x² + 8 x + 16 ) = 94   Answer : B ) 
After that we will continue like this:
5 ( x + 4 )² = 94 
( x + 4 )² = 18.8 ... etc

Can someone help me asap please
lutik1710 [3]

Answer:

The answer is $19.44

Step-by-step explanation:

First you have to find 25% of $28.80 (which is 7.20). Then, you subtract the $7.20 from your 28.80. You do that because you are getting a 25% discount. Then, you find 10% of $21.60 (your answer for the 25% discount) and you subtract 10% of $21.60. After that, you get your total of $19.44.

I hope you find this helpful.

Simplify (4 √ 14 + 4 √ 10 ) ( 3 √ 7 − 4 √ 5 )
Iteru [2.4K]

Answer:

4 sqrt(2) - sqrt(70)

Step-by-step explanation:

Simplify the following:

(4 sqrt(14) + 4 sqrt(10)) (3 sqrt(7) - 4 sqrt(5))

Factor 4 out of 4 sqrt(14) + 4 sqrt(10) giving 4 (sqrt(14) + sqrt(10)):

4 (sqrt(14) + sqrt(10)) (3 sqrt(7) - 4 sqrt(5))

(sqrt(10) + sqrt(14)) (3 sqrt(7) - 4 sqrt(5)) = sqrt(10) (-4 sqrt(5)) + sqrt(10)×3 sqrt(7) + sqrt(14) (-4 sqrt(5)) + sqrt(14)×3 sqrt(7) = -20 sqrt(2) + 3 sqrt(70) - 4 sqrt(70) + 21 sqrt(2) = sqrt(2) - sqrt(70):

Answer:  4 sqrt(2) - sqrt(70)
