Mathematics

valina [46]3 years ago

Answer:

6 and x - 5

Step-by-step explanation:

Given expression,

6x-30

Since, factor of a number or an expression is obtained after breaking up the number or expression,

Or we can say a number is always divisible by its factor.

\because 6x - 30 = 6x - 6\times 5 = 6(x-5)  ( By the converse  of distributive property )

Thus, 6 and x - 5 are the factors of 6x - 30.

So you have 6x-30. The only factor I can think of for this is x+5. Because you have 6(x+5)= 6x+30

SOMEONE PLZ HELP
taurus [48]

Answer:

2(x+4)

Step-by-step explanation:

Tom ate four more pieces of fruit than Janet. Sylvia ate twice as many pieces of fruit as Tom. If x represents the number of pieces of fruit that Janet ate, write an expression to represent the amount of fruit that Sylvia ate.

Janet: (X)

Tom: X+4

Sylvia: 2(X+4)

I started by making listing out who did what. Janet is stated as clearly X, so that's all we need for her.

The question says Tom ate four more pieces of fruit than Janet. This is simple addition since you're adding four to Janet's amount of fruit. Therefore this makes Tom's equation X+4.

Then Sylvia eats TWICE the amount as Tom. In simpler terms, she's doubling the amount of food Tom eats. Doubling something is simply multiplying it by two. Therefore, we take Tom's amount eaten, which we made into an equation in the paragraph before this one, and multiply it by two.

Placing parenthesis around Tom's equation means that that part is solved before its multiplied. We do this because we need to acknowledge that X+4 is its own equation that needs to be clarified/solved before being doubled. So, the answer is 2(X+4)

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

y-intercept (0, 5)

Point (1, 2)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{2-5}{1-0}
  2. Subtract:                              m=\frac{-3}{1}
  3. Divide:                                 m=-3

<u>Step 3: Write Equation</u>

<em>Plug in variables into the general form.</em>

PLEASE HELP ME WITH THIS
NeX [460]

In this question , we have to use sine law, which is

\frac{sin \ Q}{PR} = \frac{sin \ P}{QR}

\frac{sin73}{68} =  \frac{sin \ P }{47.6}

sin  \ P = \frac{47.6 sin 73}{68}

P = sin^{-1} ( \frac{ 47.6 sin73}{68}) = 42

Correct option is b.
