Choose the number sentence that shows the distributive property of multiplication over addition.

Mathematics
1 answer:
Anarel [89]3 years ago
4 0

we know that

distributive property of multiplication over addition:

a \times (b+c)=a \times b + a \times c

now, we will verify each options

option-A:

3 × (4 + 5) = (3 × 4) + (3 × 5)

We can see that both sides match with property

so, this is TRUE

option-B:

3 × (4 + 5) = (3 + 4) × (3 + 5)

We can see that right side does not match with property

so, this is FALSE

option-C:

3 × (4 + 5) = (3 × 4) + 5

We can see that right side does not match with property

so, this is FALSE

Determine whether y varies with x. If so, find the constant of variation and write the function rule.
ira [324]

Answer:  Yes, y does vary directly with x.

Constant of variation = 1/4

The function rule is  y = (1/4)x

=========================================================

Explanation:

Let's assume that y does vary directly with x.

If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.

Solving for k gets us k = y/x

For each row, divide the y value over the x value

  • row one: k = y/x = 14/56 = 0.25
  • row two:  k = y/x = 20/80 = 0.25
  • row three: k = y/x = 22/88 = 0.25

Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.

So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x

I'm lost I need help
dangina [55]
So set both equations equal to each other then solve out of x and plug it back into the x equation to find the angles so start with x+5=2x+10 then subtract x from 2x and you will have 1x then subtract 10 from 5 leaving you with negative 5 then x equals negative 5 and then plug it back into the equation so for example 2 times negative 5 equals negative 10 plus positive 10 equals 0 so therefore x equals 0

Find the value of x if 196^×=14​
castortr0y [4]

Answer:

x = \frac{1}{2}

Step-by-step explanation:

Note that \sqrt{196} = 14

Expressed in exponent form as

196^{\frac{1}{2} } = 14, thus

x = \frac{1}{2}
