answer:



x=-4/7 and the slope is 7
garri49 [273]3 years ago

Answer:

3

Step-by-step explanation:

The slope of a line is the rate of change

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table

m = \frac{4-12}{0-2} = \frac{-8}{-2} = 4

y = 7x + 4 ← is in slope- intercept form

with slope m = 7

Difference between rates of change = 7 - 4 = 3

Answer:

The answer is Congruent: (x,y)-(x+5,y), (x,y)-(x,-y),(x,y)-(-x,-y) Not Congruent: (x,y)-(5x,5y)-(x,y)-(0.5x,0.5y). Or the answer for congruent is answer choice 1, 4 and 5. Not Congruent is answer choice 2 and 3.

3. Find the value of p in each of the following when f(x) is divided by d(x), with the help of remainder theorem:
ipn [44]

The remainder theorem says that dividing a polynomial <em>f(x)</em> by a 1st-degree polynomial <em>g(x)</em> = <em>x</em> - <em>c</em> leaves a remainder of exactly <em>f(c)</em>.

(a) With <em>f(x)</em> = <em>px</em> ³ + 4<em>x</em> - 10 and <em>d(x)</em> = <em>x</em> + 3, we have a remainder of 5, so

<em>f</em> (-3) = <em>p</em> (-3)³ + 4(-3) - 10 = 5

Solve for <em>p</em> :

-27<em>p</em> - 12 - 10 = 5

-27<em>p</em> = 27

<em>p</em> = -1

(b) With <em>f(x)</em> = <em>x</em> + 3<em>x</em> ² - <em>px</em> + 4 and <em>d(x)</em> = <em>x</em> - 2, we have remainder 8, so

<em>f</em> (2) = 2 + 3(2)² - 2<em>p</em> + 4 = 8

-2<em>p</em> = -10

<em>p</em> = 5

(you should make sure that <em>f(x)</em> was written correctly, it's a bit odd that there are two <em>x</em> terms)

(c) <em>f(x)</em> = 2<em>x</em> ³ - 4<em>x</em> ² + 6<em>x</em> - <em>p</em>, <em>d(x)</em> = <em>x</em> - 2, <em>R</em> = <em>f</em> (2) = 18

<em>f</em> (2) = 2(2)³ - 4(2)² + 6(2) - <em>p</em> = 18

12 - <em>p</em> = 18

<em>p</em> = -6

The others are done in the same fashion. You would find

(d) <em>p</em> = 14

(e) <em>p</em> = -4359

(f) <em>p</em> = 10

(g) <em>p</em> = -13/2 … … assuming you meant <em>f(x)</em> = <em>x</em> ⁴ + <em>x</em> ³ + <em>px</em> ² + <em>x</em> + 20

what are the steps to solve 3.5(c-8)+c=12.5? I already went on a different website and found out the answer is nine. I plugged i
LekaFEV [45]
3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9

The correct answer is 9~
