Answer:

y=-1/3x

Step-by-step explanation:

We use the linear equation of y=mx+c

Y=c

We know that y=0 and that m=-1/3, therefore we plug it in the formula.

y=-1/3x+0

y=-1/3x

Answer:

X + 3y = 0

Step-by-step explanation:

Given

y-intercept (b) = 0

Slope (m) = - ⅓

Now w

Equation in slope intercept form

y = mx + b

y = - ⅓x + 0

3y = - x

X + 3y = 0

What is f(-2) of the function given below? *<br> f(x) = 3x2 - 4x + 1
slava [35]

Answer:

f(-2) = 21

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 4x + 1

f(-2) is x = -2

Step 2: Substitute and Evaluate

f(-2) = 3(-2)² - 4(-2) + 1

f(-2) = 3(4) + 8 + 1

f(-2) = 12 + 9

f(-2) = 21

What is the value of -2xy if x = -1 and y = 6? <br><br> A. 12 <br> B.-12 <br> C. 26 <br> D. 8
uranmaximum [27]

Answer: A

Step-by-step explanation:

If we are given the values of x and y, we just have to plug them into the expression. So -2xy means -2(-1)(6) which is 12. 12 corresponds to A so A is the correct answer.

  • Addition Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2x - 9y = 11

<em>x</em> = 7

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                                                                                                  2(7) - 9y = 11
  2. Multiply:                                                                                                             14 - 9y = 11
  3. [Subtraction Property of Equality] Subtract 14 on both sides:                       -9y = -3
  4. [Division Property of Equality] Divide -9 on both sides:                                 y = 1/3

Write the expression as the sine or cosine of an angle sin(pi/7) cos(x) + cos(pi/7) sin(x)
Natasha_Volkova [10]

Answer:

\sin(\frac{\pi}{7}+x)

Step-by-step explanation:

We are going to use the identity

\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)

because this identities right hand side matches your expression where

a=\frac{\pi}{7} and b=x.

So we have that \sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x) is equal to \sin(\frac{\pi}{7}+x).
