Answer:

x= - 35 over 89

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x−23+5x=18(x−1)

x+−23+5x=(18)(x)+(18)(−1)(Distribute)

x+−23+5x=18x+−18

(

x+5x)+(−23)=18x−18(Combine Like Terms)

x+−23=18x−1837

x−23=18x−18

Step 2: Subtract 18x from both sides.

x−23−18x=18x−18−18x

−89

x−23=−18

Step 3: Add 23 to both sides.

−89

x−23+23=−18+23

−89

x=5

Step 4: Multiply both sides by 7/(-89).

F(x)=-3x+21,find x when f(x)=6

balu736 [363]

Answer:

x=5

Step-by-step explanation:

F(x)=-3x+21,

f(x)=6 = -3x+21

6 = -3x+21

Subtract 21 from each side

6-21 = -3x+21-21

-15 = -3x

Divide each side by -3

-15/-3 = -3x/-3

5 = x

1. round the result to 2 decimal places. -0.9x+2.8=4.1

lora16 [44]

1. -0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
c) -1.44

Find the coordinates of the midpoint of the segment given its endpoints.

Vesna [10]

Answer:

(2, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{1}{2}$ (x₁ + x₂ ) , $\frac{1}{2}$ (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus

midpoint = [ $\frac{1}{2}$ (5 - 1), $\frac{1}{2}$ (8 - 4 ) ] = (2, 2 )

Answer:

The graph is shown in the following image

Step-by-step explanation:

The parent function of $f(x) = | x + 1 | +2$ is $y = | x |$

The graph of $y = | x |$ is the union of two lines:

$y = x$ for $x\geq0$

$y = -x$ for $x$

The vertex of this graph is in point (0,0)

The graphic is shown in the attached image.

Then, if we do $y = f(x + 1)$ to the parent function we get:

$y = | x + 1 |$

This transformation shifts the graph of $y = |x|$ 1 unit to the left

Then, if we make the transformation $y = f(x) + 2$ to the function $y = | x + 1 |$ we obtain:

$y = | x + 1 | +2$

This transformation displaces the graph of the function $y = | x + 1 |$ 2 units up on the y axis.

So, if the vertex of the main function $y = | x |$ was at point (0,0), the vertex of the function $f(x) = |x + 1| +2$ has its vertex in the point (-1, 2).

The graph is shown in the following image
