Answer: The required value of x is $\dfrac{4}{19}.$

Step-by-step explanation: Given that the following equation relates proportional quantities x and y :

$y=19x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the value of x when y is 4.

To find the value of x, we must substitute y = 4 in equation (i) and find the corresponding value of x.

From equation (i), we get

$y=19x\\\\\Rightarrow 4=19x\\\\\Rightarrow x=\dfrac{4}{19}.$

Thus, the required value of x is $\dfrac{4}{19}.$

Which four inequalities can be used to find the solution to this absolute value inequality?

natita [175]

The four inequalities that can be used to find the solution of 3 ≤ |x + 2| ≤ 6 is x + 2 ≤ 6, x + 2 ≥ -6, x + 2 ≥ 3 and x + 2 ≤ -3

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the inequality:

3 ≤ |x + 2| ≤ 6

Hence:

x + 2 ≤ 6, -(x + 2) ≤ 6, 3 ≤ x + 2 and 3 ≤ -(x + 2)

This gives:

x + 2 ≤ 6, x + 2 ≥ -6, x + 2 ≥ 3 and x + 2 ≤ -3

The four inequalities that can be used to find the solution of 3 ≤ |x + 2| ≤ 6 is x + 2 ≤ 6, x + 2 ≥ -6, x + 2 ≥ 3 and x + 2 ≤ -3

Question 5- Please help. Using a piece of pizza explain what arc length and area of the sector mean in two to three sentences.

pickupchik [31]

Answer:

You'd have to look at the size of the pizza and then measure the size of the arc for each slice. The slice of pizza is how many topping is on it. The sector is how much pizza you are consuming from the center to the crust. The arc is the crust around the pizza.

Minchanka [31]

$\frac{1}{6}$ : Common ratio

Check:
= $-\frac{1}{12}$ ÷ $\frac{1}{6}$
= $-\frac{1}{12}$ × 6
= $-\frac{1}{2}$

= $-\frac{1}{2}$ ÷ $\frac{1}{6}$
= $- \frac{1}{2}$ × 6
=-3
