Answer:

y = m x + b      standard equation for straight line

-2 = 3 *2 + b    to satisfy above equation

b = -8

therefore

y = 3 x - 8

if x = 2 then y = -2

Answer:

  20 g/cm³

Step-by-step explanation:

The volume of the prism is the product of the area of its triangular base and its height. The triangle area is ...

  A = 1/2bh

  A = 1/2(16 cm)(8 cm) = 64 cm²

The height of the prism is 20 cm, so its volume is ...

  V = Bh = (64 cm²)(20 cm) = 1280 cm³

The density of the ingot is the ratio of its mass to its volume.

  ρ = M/V = (25,600 g)/(1280 cm³) = 20 g/cm³

The density of the ingot is 20 g/cm³.

Answer:

The given graph is represents a relation, Option C is correct.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The graph is classified as a relation (non-function).

A relation is any set of ordered pairs, and a function is a special type of relation where each input (x-value) corresponds to exactly one output (y-value).

In other words, for a function, there are no repeated x-values with different y-values.

Linear Function Graph has a straight line so the graph is not linear function.

A nonlinear function is a function whose graph is not a straight line.

Its graph can be any curve other than a straight line.

Hence, the given graph is represents a relation, Option C is correct.

Answer:

Step-by-step explanation:

You could graph it. I'll do that at the bottom. What you need is a value that is - on either 2 or 3 and a plus on the other one.

y=12*2^3 - 32x^2 + 17

y = 12 * 8 - 32*2^2 + 17

y = 96 - 128 + 17

y = -15

Now when x = 3 should give you something above the x axis

y = 12*3^3 - 32*9 + 17

y = 324 - 288 + 17

y = 53

What this indicates is that somewhere between 2 and 3 the graph crosses the x axis. The graph should indication that.

Answer:

Angle 5 should be 60

Step-by-step explanation:

Angle 2 and angle 4 are the same because they are Corresponding Angles. so if the lines m and n equal 180 then you subtract 120 from 180 and you get 60 so 5 ,7, 1 and 3 are 60 degrees

Answer:

The correct choice is option A) (-1, 0) and (4, 5).

Step-by-step explanation:

See the attached graph below.

As you can see, the two equations intersect at (-1, 0) and (4, 5).

Answer:

Angle B is 52 degrees

Step-by-step explanation:

The outer angle 112 adds up with the inner angle to make 180. So angle C is 68. All the angles should add up to 180, so add them all together.

68+4y+3y+7 = 180

75+7y = 180

7y = 105

y = 15

To double-check this, plug 15 into y and add up all the angles, it should add up to 180.

3(15)+7 = 52

4(15) = 60

68+60+52 = 180
