Answer:

x =9/4

Step-by-step explanation:

log3(4x) = 2

Raise each side to the base of 3

3^ log3(4x) = 3^2

We know that 3log3 is 1

4x = 9

Divide each side by 4

4x/4 = 9/4

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 45°

Adjacent Leg = 25

Hypotenuse = x

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(45^\circ) = \frac{x}{25}$
[Multiplication Property of Equality] Multiply 25 on both sides: $\displaystyle 25cos(45^\circ) = x$
Rewrite: $\displaystyle x = 25cos(45^\circ)$
Evaluate: $\displaystyle x = \frac{25\sqrt{2}}{2}$

Help Please!!!! I'm Going To Get A Test Tomorrow On This And Ion Know How To Do These

Dmitriy789 [7]

y=3x-2 y=-2x+8

3x-2=-2x+8 (plus 2 each side)

3x=-2x+6 (plus 2x each side)

5x=6 (divide by 5 each side)

x=1.2

Plug x back into an equation

y=3(1.2)-2

y=3.6-2

y=1.6

Answer: (1.2, 1.6)

Step-by-step explanation:

A response error shows the lack of accuracy in the customer responses to the survey questions. A response error can be caused by a questionnaire that requires framing improvements, misinterpretation of questions by interviewers or respondents, and errors in respondents' statements. Some responses are influenced by the answers provided to previous questions, which introduces response bias.
