Answer:

x=

Step-by-step explanation:

using distributive property, you multiply 5 by x and by 2, which gets you 5x and 10

5(x-2)=30

5x-10=30

5x=40

x=8

Answer:

x = 8

Step-by-step explanation:

5(x-2)=30

Distribute

5x- 10 = 30

Add 10 to each side

5x-10+10 = 30+10

5x= 40

Divide by 5

5x/5=40/5

x = 8

Which expression below has the LEAST value?
Alexandra [31]

Answer: A

Step-by-step explanation:
Your answer is A.

Value of 3.78 x 10=37.8

Value of 5.99 x 102=699.98

value of 7.35 x 10-12=61.5

Value of 9.46 x 10-10=84.6.

Least value to greatest value

3.78 x 10=37.8 Least value

7.35 x 10 - 12=61.5 Sencond least value

9.46 x 10 - 10=84.6  Sencond greatest value

5.99 x 102=699.98  Greatest value

Hope it helps have a great day:)

Given that (4,-7 is on the graph of f(x), find the corresponding point for the function f(x)+4
alexandr402 [8]

Answer:

The corresponding point for the function f(x)+4 would be (4,-3)

Step-by-step explanation:

Since the transformation is outside of the parenthesis, that means the y-coordinate is only affected.

add 4 to -7 and you get -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
