Answer:

y = -5x + 20

Step-by-step explanation:

(2,10) and (3,5)

Slope = (y-y)/(x-x)

(10-5)/(2-3) = 5/-1 = -5

y-intercept (any point) = y - (slope times x)

y-intercept = 5 - (-5)(3) = 5 + 15 = 20

Answer:

y = -5x + 20

Step-by-step explanation:

Lets start with the first given values for x and y

(2,10)

Lets try out the first equation

y = 5x + 4

y = 5(2) + 4

y = 14

This equation wouldn't work because the y value is not 10 when the x value is 2

y = 5x + 20

y = 5(2) + 20

y = 30

This equation doesn't work either

y = -5x + 20

y = -5(2) + 20

y = -10 + 20

y = 10

This would be the correct equation since your y value is 10 when the x value is 2

a sequence starts a 200 and 30 is subtracted each time 200,170,140 what are the first two numbers in the sequence that are kess
Snowcat [4.5K]
<h3>Answer:  -10 and -40</h3>

===============================================================

Explanation:

a = 200 = first term

d = -30 = common difference

Tn = nth term

Tn = a + d(n-1)

Tn = 200 + (-30)(n-1)

Tn = 200 - 30n + 30

Tn = -30n + 230

Set Tn less than 0 and isolate n

Tn < 0

-30n + 230 < 0

230 < 30n

30n > 230

n > 230/30

n > 7.667 approximately

Rounding up to the nearest whole number gets us n \ge 8

So Tn starts to turn negative when n = 8

We can see that,

Tn = -30n + 230

T7 = -30*7 + 230

T7 = 20

and

Tn = -30n + 230

T8 = -30*8 + 230

T8 = -10 is the 8th term

and lastly

Tn = -30n + 230

T9 = -30*9 + 230

T9 = -40 is the ninth term

Or once you determine that T7 = 20, you subtract 30 from it to get 20-30 = -10 which is the value of T8. Then T9 = -40 because -10-30 = -40.

What does the remainder theorem conclude given that f(x)/x+3 has a remainder of 11?
maw [93]

The conclusion of the remainder theorem about a situation where a function; f(x) is divided by (x+3) and has a remainder of 11 is that; f(-3) = 11.

<h3>What does the remainder theorem conclude given that f(x)/x+3 has a remainder of 11?</h3>

It follows from the task content that f(x)/x+3 has a remainder of 11.

On this note, it follows from the remainder theorem regarding the division of polynomials that; when; x + 3= 0; x = -3 and hence;

f(-3) = 11.

Ultimately, the inference that can be drawn from the remainder theorem statement as in the task content is; f(-3) = 11.

Someone help me please
Gemiola [76]

Answer:

x=2\sqrt{6}

Step-by-step explanation:

Use the Pythagorean theorem:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse. Insert the values:

\sqrt{10}^2+\sqrt{14}^2=x^2

Simplify exponents using the rule \sqrt{x}^2=x :

10+14=x^2

Simplify addition:

24=x^2\\x^2=24

Find the square root:

\sqrt{x^2}=\sqrt{24}\\  x=\sqrt{24}

Simplify in radical form: Find a common factor of 24 that is a perfect square:

\sqrt{24}=\sqrt{4*6}

Separate:

\sqrt{4}*\sqrt{6}

Simplify:

2*\sqrt{6}\\x=2\sqrt{6}

Finito.
