Answers

Answer 1

Answer:

Option B: 3

Step-by-step explanation:

#1: Substitute in 6 for [tex]y[/tex] and 3 for [tex]x[/tex]: [tex]13=(3)(6)-5[/tex]

#2: Multiply 3 and 6: [tex]13=18-5[/tex]

#3: Evaluate the equation: [tex]13=18-5[/tex] → [tex]13=13[/tex]

#4: Check if the solution is equal: [tex]13=13[/tex] ✓

[tex]x[/tex] is equal to 3 (Option B).

sin(x)=-0.7

Answers

Answer:

A. [tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]

B. [tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]

Step-by-step explanation:

The negative value of the sine function indicates that [tex]x[/tex] is located at third and fourth quadrants. Besides, this function has a period of 360º. There are two families of solutions:

[tex]x_{1} = \sin^{-1} (-0.7)[/tex]

[tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]

[tex]x_{2} = \sin^{-1} (-0.7)[/tex]

[tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]

Hence, right answers are A and B.

Answer:

A) x= -4

Step-by-step explanation:

To solve you must isolate the variable. Do this by using the properties of equality to subtract and divide numbers from both sides of the equation. First, subtract 8x to move all x terms to the right side.

-48=12x

Then, divide both sides by 12

1) Find the linear equation from the
graph:

Answers

Answer:

y = -1/2 x - 3

Step-by-step explanation:

Use the coordinates from the graph:

(-6, 0) and (0, -3)

Slope m = -3-0/0-(-6)

m = -3/6

m = -1/2

The y-intercept is -3 (point where the line meet the y intercept)

Substitute unto the expression y = mx+c

y = -1/2 x - 3

Hence the required equation is y = -1/2 x - 3
