The length of EF is 3.8

To do this, we make use of the following law of sines

EF/sin(D)= DE/sin(F)

So, we have:

EF/sin(75)= 3/sin(50)

This gives

EF = sin(75) * 3/sin(50)

Evaluate the product

EF = 3.8

Hence, the length of EF is 3.8

Answer:

There are two cases when the solution set of an inequality will be the empty set or the set of all real numbers.

The first case is when the inequality is always false no matter what value is chosen for the variable. For example, the inequality x > 5 has no solution because there is no value of x that is greater than 5. In this case, the solution set is the empty set.

The second case is when the inequality is always true no matter what value is chosen for the variable. For example, the inequality x > -∞ has infinitely many solutions because there is no value of x that is not greater than -∞. In this case, the solution set is the set of all real numbers.

The coordinates of the midpoint of CD with endpoint at C(-7,-2) and D(-3,-5) is E(-5, -3.5)

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

Let (x, y) represent the coordinate of the midpoint E. Point E is the midpoint of CD, hence:

x = [(-7) + (-3)] / 2 = -5

y = [(-2) + (-5)] / 2 = -3.5

The coordinates of the midpoint of CD with endpoint at C(-7,-2) and D(-3,-5) is E(-5, -3.5)

Answer:

The solution to the inequality [tex]$2|v-7|-4 \geq 42$[/tex] in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].

Step-by-step explanation:

An absolute value inequality [tex]$2|v-7|-4 \geq 42$[/tex] is given.

It is required to solve the inequality and write the solution in interval form.

To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.

Step 1 of 4

The given absolute value inequality is [tex]$2|v-7|-4 \geq 42$[/tex].

Add on both 4 sides,

[tex]$$\begin{aligned}&2|v-7|-4 \geq 42 \\&2|v-7|-4+4 \geq 42+4 \\&2|v-7| \geq 46\end{aligned}$$[/tex]

Step 2 of 4

Divide by 2 on both sides,

[tex]$$\begin{aligned}&\frac{2|v-7|}{2} \geq \frac{46}{2} \\&|v-7| \geq 23\end{aligned}$$[/tex]

The inequality can be written as [tex]$v-7 \leq 23$[/tex] and [tex]$v-7 \geq-23$[/tex]

Step 3 of 4

First solve the inequality, [tex]$v-7 \leq 23$[/tex].

Add 7 on both sides,

[tex]$$\begin{aligned}&v-7 \leq 23 \\&v-7+7 \leq 23+7 \\&v \leq 30\end{aligned}$$[/tex]

Step 4 of 4

Solve the inequality [tex]$v-7 \geq-23$[/tex].

Add 7 on both sides,

[tex]$$\begin{aligned}&v-7 \geq-23 \\&v-7+7 \geq-23+7 \\&v \geq-16\end{aligned}$$[/tex]

The solution of the inequality in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].

Answer:

1. No.

2. Yes, there is no solution here.

Step-by-step explanation:

The former:

[tex]8(5x - 3) = 6(-3x - 4); \\ 8 * 5x - 8 * 3 = 6 * (-3x) - 6 * 4; \\ 40x - 24 = -18x - 24; \\ 40x + 18x = -24 + 24; \\ 58x = 0; \\ x = 0.[/tex]

[tex]\{0\}[/tex] is our set of solutions.

The latter:

[tex]3x - 13 = 7(x + 2) - 4(x - 7); \\ 3x - 13 = 7x + 7 * 2 - 4x - 4 * (-7); \\ 3x - 13 = 7x + 14 - 4x + 28; \\ 7x - 4x - 3x = -13 - 14 - 28;\\ 0x = 55; \\ x \in \emptyset.[/tex]

In other words, there is not any solution from the set of real numbers that suits us.

Answer:

If the exterior of the house is 2000 square feet and each gallon of paint covers 350 square feet.

Then she needs to buy 6 gallons of paint.

Step-by-step explanation:

Dividing the total area by the area that each gallon of paint covers we get,

[tex]$\frac{2000}{350} \times \frac{50}{50}=\frac{40}{7}$$[/tex]

Now, performing long division we get,

[tex]$7\overset{5}{\overline{\left){\begin{align} & 40 \\ & \underline{35} \\ & \underline{05} \\ \end{align}}\right.}}$$[/tex]

She needs five gallons of paint fully and some amount of the sixth gallon because we get a remainder.

She can't buy paint in fraction, hence she has to buy 6 gallons of paint.

Answer:
