5x + (1x+6)= 78 BARDZO POTRZEBUJĘ

kifflom [539]

Answer: x = 12

Step-by-step explanation:

1. add 5x + 1x which will equal 6x so now your equation is: 6x + 6 = 78

2. subtract 6 from 78 to get 72: 6x = 72

3. divide 72 by 6x to get your answer 12

Find the indicated limit, if it exists.

kondor19780726 [428]

Answer:

d) The limit does not exist

General Formulas and Concepts:

Calculus

Limits

Right-Side Limit: $\displaystyle \lim_{x \to c^+} f(x)$
Left-Side Limit: $\displaystyle \lim_{x \to c^-} f(x)$

Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$

Limit Property [Addition/Subtraction]: $\displaystyle \lim_{x \to c} [f(x) \pm g(x)] = \lim_{x \to c} f(x) \pm \lim_{x \to c} g(x)$

Step-by-step explanation:

*Note:

In order for a limit to exist, the right-side and left-side limits must equal each other.

Step 1: Define

Identify

$\displaystyle f(x) = \left\{\begin{array}{ccc}5 - x,\ x < 5\\8,\ x = 5\\x + 3,\ x > 5\end{array}$

Step 2: Find Right-Side Limit

Substitute in function [Limit]: $\displaystyle \lim_{x \to 5^+} 5 - x$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle \lim_{x \to 5^+} 5 - x = 5 - 5 = 0$

Step 3: Find Left-Side Limit

Substitute in function [Limit]: $\displaystyle \lim_{x \to 5^-} x + 3$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle \lim_{x \to 5^+} x + 3 = 5 + 3 = 8$

∴ Since $\displaystyle \lim_{x \to 5^+} f(x) \neq \lim_{x \to 5^-} f(x)$ , then $\displaystyle \lim_{x \to 5} f(x) = DNE$

Find the measure of the arc or angle indicated. NO LINKS.

Advocard [28]

9514 1404 393

Answer:

10. A) 120°

11. D) 40°

12. D) 54°

13. A) 101°

Step-by-step explanation:

The applicable rules of angles and arcs are ...

the whole is the sum of the parts
arcs of a circle total 360°
an inscribed angle intercepts an arc of twice its measure

__

10) Angles C and L intercept the same arc (DE) so will have the same measure.

15x = 16x -4

4 = x . . . . . . . . add 4-15x

arc DE = 2(15x) = 30(4) = 120 . . . degrees

__

11) Arc VW is twice the measure of angle X, so ...

9x +8 = 2(5x)

8 = x . . . . . . . . . subtract 9x

∠VXW = 5x = 5(8) = 40 . . . degrees

__

12) Arc EFG is twice the measure of angle W, so ...

70° +FG = 2(88°)

FG = 106° . . . . . . . . . subtract 70°

Arc FGW is twice the measure of angle E, so ...

106° +GW = 2(80°)

GW = 54° . . . . . . . . . . subtract 106°

__

13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.

RS +ST +TR = 360°

119° +2(70°) +TR = 360°

TR = 101° . . . . . . . . subtract 259°
