Answer:

The Distributive Property is used, which consists of multiplying the factor by each of the addends.

2x (x-4) = 2x.x-2x.4 = 2 x 2 -8x

It is better to understand what you are doing. Hope this can help you :)

Answer:

slope: $\frac{3}{4}$ ; y-intercept: 1

Step-by-step explanation:

First, you must rearrange the function into y = mx + b form:

2x + x = 4(y - 1)

Simplify both sides:

3x = 4y - 4

Subtract 3x and 4y from both sides:

-4y = -3x - 4

Divide both sides by -4:

y = $\frac{3}{4} x$ + 1

Now that it is in y = mx + b form, you can find the slope and y-intercept. In y = mx + b form, m is the slope and b is the y-intercept. Therefore:

m = $\frac{3}{4}$ = slope

b = 1 = y-intercept

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump wil

Bogdan [553]

Answer : Probability that the pumping system will fail on any given day = 0.005

Explanation:

Probability that only older pump fail = P(A) = 0.10

Probability that only newer pump fail = P(B) = 0.05

Since they are independent events ,

then the conditions will be

P(A∩B) = P(A). P(B)

= 0.10 ×0.05

= 0.005

Hence, the probability will fail on any given day = 0.005

notsponge [240]

Answer:

60%

Step-by-step explanation:

There are 20 pieces of fruit in a basket and 12 of them are oranges what percentage of the pieces of fruit in the basket are orange show your work in the box and circle your answer

Total oranges in the basket = 20

Number of oranges = 12

what percentage of the pieces of fruit in the basket are orange

= Number of oranges / Total pieces of fruits × 100

= 12/20 × 100

= 0.6 × 100

= 60%

Percentage of the pieces of fruit in the basket that are oranges = 60%

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

kotegsom [21]

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

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

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
