I need help solving this :/

Mathematics

The equivalents are ...

  • A. 10 · (4 + 3)
  • B. 10 · 3 + 10 · 4
  • C. (3 + 4) · 10

_____

The expression in D evaluates to 30+4 = 34, not 10·7 = 70.

In A, (4 + 3) is equivalent to (3 + 4) by the commutative property of addition. The commutative properties of multiplication and addition allow you to swap the order of the operands with no effect on the result.

In B, 10·3 +10·4 is equivalent to 10·(3+4) by the distributive property of multiplication over addition.

In C, (3+4)·10 is equivalent to 10·(3+4) by the commutative property of multiplication.

M is the midpoint of LN. what is LM?
Serjik [45]
Given, 

M is the midpoint of LN.

Thus,

LM = MN

3x = 2x + 2

3x - 2x = 2

x = 2

Hence,

LM = 3x = 3 * 2 = 6

Hence, LM is 6 units.

If f(x) =5x-6 what is the inverse of f(x)
Akimi4 [234]

Replace f(x) with y:

y = 5x-6

Swith the variables:

x = 5y -6

Now solve for y:

add 6 to each side:

x +6 = 5y

Divide both sides by 5:

y = (x+6)/5

Now replace y with the inverse function f^-1 (x):

f^-1(x) = (x+6)/5

Answer:

Answer is option b)

<em>Answer is </em><em>given below with explanations</em><em>. </em>

Step-by-step explanation:

a \: walking \: path \: is \: represented \: by \:  \\ y =  - 4x - 6 \\ 4x + y + 6 = 0 \\ given \: that \\ a \: new \: path \: will \: be \: built \: perpendicular  \\ \: to \:  \: the \: walking \: path \\ the \: equation \: of \: the \: line \: perpendicular \: to \\ 4x + y + 6 = 0 \: is \\ x - 4y + k = 0 \\ since \: it \: passes \: through \: ( - 4,10) \\ substitute \: x \:  =  - 4\: and \: y = 10 \: in \: required \: equation \\  - 4 - 4(10) + k = 0 \\ k = 44 \\ then \: the \: equation \: is \\ x - 4y + 44 = 0 \\ adding \: 4y \: on \: both \: sides \\ x + 44 = 4y \\ dividing \: by \: 4 \: on \: both \: sides \\ y =  \frac{x}{4}  + 11 \\ y =  \frac{1}{4} x + 11 \\ so \: the \: answer \: is \: option \: b) \:   \frac{1}{4} x + 11
