Answer:

-15

Step-by-step explanation:

you start by collecting like terms which will be

-x=20-5.

which is -x=15

divide both sides by -1

therefore the Ans=-15

<h3>Answer:   x > -15</h3>

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

Work Shown:

-x+5 < 20

-x+5-5 < 20-5 ... subtract 5 from both sides

-x < 15

-x/(-1) > 15/(-1) ... divide both sides by -1

x > -15

Note how the inequality sign flips when we divide both sides by a negative number.

-----------

Alternative method

-x+5 < 20

-x+5+x < 20+x ... add x to both sides

5 < 20+x

5-20 < 20+x-20 ... subtract 20 from both sides

-15 < x

x > -15

We get the same answer.

What is the measure of A
SCORPION-xisa [38]

Answer:

A. 60°

Step-by-step explanation:

From the diagram, in triangle ABC,

AB=BC=CA=15 units.

This means triangle ABC is an equilateral triangle.

All angles in equilateral triangle are congruent. The sum of all interior angles in triangle is always 180°, so one angle of equilateral triangle is equal to 60°. Thus,

∠A=∠B=∠C=60°

For each value of kk specified in parts (a)–(e), plot the set of points in the plane that satisfy the equation
son4ous [18]

Answer:

Seee answer below.

Step-by-step explanation:

a. k = −1

If K=-1 the equation gets this form:

(x^2/-1) -y^2=1

There aren't natural numbers that being negative, adding them, we get 1 as result. So there is no graph for this equation.

b. k = 1

(x^2/1) -y^2=1

This is the natural form of the equation of an hyperbola. Attached you can find the graph.

c. k = 2

(x^2/2) -y^2=1

This is the natural form of the equation of an hyperbola. Attached you can find the graph.

d. k = 4

(x^2/4) -y^2=1

This is the natural form of the equation of an hyperbola. Attached you can find the graph.

e. k = 10

(x^2/10) -y^2=1

This is the natural form of the equation of an hyperbola. Attached you can find the graph.

f. k = 25

(x^2/25) -y^2=1

This is the natural form of the equation of an hyperbola. Attached you can find the graph.

g. Describe what happens to the graph of

x2 / k − y2 = 1 as k → [infinity].

As K is increasing the value of X will be tending to 0. So the equation for this will be:

− y^2 = 1.The solution for this is in the domain of the imaginary numbers.

What is the measure of ∠PQR ? <br><br> Enter your answer in the box. °
xxTIMURxx [149]
The 3 inside angles of a triangle need to = 180 degrees
 you are given 70 and 80 which = 150 degrees  ( 70 +80 = 150)

so the missing angle (PQR) = 180 - 150 = 30 degrees
