Semenov [28]
  1. the number 0 — additive identity
  2. a(b+c) = ab+ac — the distributive property
  3. an equation containing more than one variable — literal equation
  4. the number 1 — multiplicative identity
  5. the reciprocal of a number — multiplicative inverse

If x ≠ 0, then 1/x is its multiplicative inverse — true.

The product of a number and its multiplicative inverse is 1 — true.

Which sequence is modeled by the graph below? coordinate plane showing the points 1, 2; 2, 2; 3, 2; 4, 2
prisoha [69]

We will start with plotting the x coordinates and y coordinates on the graph

The points 1, 2; 2, 2; 3, 2; 4, 2  have been plotted on the graph which has been attached as an image to the solution.

We can see that the value of y is staying constant (2) for all values of x.

Hence, the points represent the equation y = 2.

Identify an equation in point-slope form for the line perpendicular to y =3/4x -4 that passes through (-1, 7).
PilotLPTM [1.2K]

Answer:

y - 7 = -4/3(x + 1)

Step-by-step explanation:

<u>Given</u>

  • y =3/4x -4
  • (-1, 7)

<u>Convert to point slope form</u>

y - y1 = m(x - x1)

m: represents what the slope is

y - 7 = -4/3(x + 1)

<u>Distribute -4/3</u>

-4/3 * x = -4/3x

-4/3 * 1 = -4/3

y - 7 = -4/3x - 4/3

<u>Add seven in both sides</u>

21/3 -4/3 = 17/3

y = -4/3x + 17/2

<u>Answer</u>

linear equation: y = -4/3x + 17/2

point-slope form: y - 7 = -4/3(x + 1)
