In the diagram the length of segment TR can be represented by 5x-4.
masya89 [10]

Answer: The correct option is D, i.e., 15 units.

Explanation:

It is given that the  length of segment TR can be represented by 5x-4.

From figure it is noticed that the side TR and RV is equal and the length of segment RV is 2x+5. So,

5x-4=2x+5

3x=9

x=3

The value of x is 3, so the length of side RV is,

2x+5=2(3)+5=11

In triangle TRS and angle VRS,

TR=VR

\angle TRS=\angle VRS=90^{\circ}

RS=RS (common side)

By SAS rule of congruence triangle,

\triangle TRS\cong\triangle VRS

Therefore the side TS and VS are congruent sides.

From figure it is noticed that the length of side TS is 6x-3, therefore the length of side VS is also 6x-3.

VS=6x-3=6(3)-3=15

Hence, the length of side VS is 15 units and option D is correct.

How do I solve -3(3+x)+(x-6)=-4 ?
zysi [14]

\huge\boxed{x=-\frac{11}{2}}

Start by distributing the -3 to the (3+x). -3(3) + (-3)(x) + (x-6) = -4

Multiply and simplify. -9-3x+(x-6)=-4

Rearrange the terms. -3x+x-9-6=-4

Combine like terms. -2x-15=-4

Add 15 on both sides. -2x=11

Divide both sides of the equation by -2. x=\boxed{-\frac{11}{2}}

HELP PLEASE?! Determine a radical function that starts at the point (-4,2) and goes to the right and decreases. The domain is al
Diano4ka-milaya [45]

Answer:

f(x) = -√(x-4) + 2

Step-by-step explanation:

(a) Start with the basic function: f(x) = √x.

This would be the top half of a horizontal parabola opening to the right (always positive).

(b) The range is y < 2. This includes negative numbers, so the function must be f(x) = -√x.

(c) The function starts at x = -4. We must shift it four units to the left. We do that by adding four units to x. The function must be f(x) = -√(x + 4). The domain is x > -4.  

(d) The function starts at y = 2. We must shift it up two units. We do that by adding two units to y. The function must be f(x) = -√(x+4) + 2. The range is y < 2.

The figure below is the graph of f(x) = -√(x+4) + 2.
