Mathematics

ira [324]3 years ago

Answer:

x=-5

Step-by-step explanation:

\dfrac{2x-20}{3}=2x

Multiply both sides by 3:

2x-20=6x

Subtract 2x from both sides:

-20=4x

Divide both sides by 4:

x=-5

Hope this helps!

Answer:

2x_20/3 = 2x

2x_20/3*3 = 2x*3

2x_20 = 6x

2x_6x = 20

-4x = 20

-4x/-4x = 20/-4x

X= -5

What is another way to write the equation 7/8 x+ 3/4 = -6
Dmitry_Shevchenko [17]

Answer:

  1) 7(x/8) + 3/4 = -6

Step-by-step explanation:

The term (7/8)x can be written as 7(x/8).

_____

The associative and commutative properties of multiplication let you put the factors (7)(1/8)(x) in any order or grouping you like.

Here, instead of (7·1/8)·x, the question is offering the rewrite 7(1/8·x), a straightforward application of the associative property.

HELP! I'll mark you the brainest and give you all my points !! (Show all work)
Paha777 [63]

1. F(3)= -2(3)-5

-6-5

F(3)=-11

2. F(3)= -2(3)^2-4

-6^2-4

36-4

F(3)=32

3. F(x)=−2x−5

For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1

For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3

For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7

For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9

The Range is:

{−1,−3,−7,−9}

4. -80, -110
