Answer:

the answer is no solution

Step-by-step explanation:

7+−3x=x+(−4)(2)+(−4)(x)(Distribute)

7+−3x=x+−8+−4x

−3x+7=(x+−4x)+(−8)(Combine Like Terms)

−3x+7=−3x+−8

−3x+7=−3x−8

Step 2: Add 3x to both sides.

−3x+7+3x=−3x−8+3x

7=−8

Step 3: Subtract 7 from both sides.

7−7=−8−7

0=−1

A polynomial of degree 3 has a double zero at 2. When x = 1 it takes the value 6 and when x = 3 it

masha68 [24]

Answer:

p(x)=(x-2)^2(x+5)

Step-by-step explanation:

p(2)=0 then p(x) =(x-2)^2(x-x1), x1=?

p(1)=6

p(3)=8

p(1)=(1-2)^2(1-x1)

6= (-1)^2 (1-x1)

6=1(1-x1)

6=1-x1

x1=-5;

then p(x) =(x-2)^2(x-(-5))=(x-2)^2(x+5)

Really: f(3)=(3-2)^2(3+5)=1*8=8

Consider the function f(x)=10^x and function g(x)=f(x+4). How will the graph of function g differ from the graph of function f?

Jobisdone [24]

Answer:

Shifts 4 units to left

Step-by-step explanation:

Given:

$\displaystyle \large{f(x)=10^x}\\\\\displaystyle \large{g(x)=f(x+4)=10^{x+4}}$

Accorded to transformation rules:

f(x + a) is shift to left a units.
f(x - a) is shift to right a units.
f(x) + a is shift up a units.
f(x) - a is shift down a units.

Since function g is f(x + 4) then function g is the graph of function f(x) that shifts to left 4 units.
