  • Slope-Intercept Form: y = mx+b, with m = slope/rate of change and b = y-intercept.

So for this to be slope-intercept form, we first have to divide both sides by 2: y=\frac{5}{2}x+5

Now that it's slope-intercept form, we see that <u>the rate of change is 5/2, or 2.5.</u>

BaLLatris [955]

Step-by-step explanation:

Abby’s Expression:

Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m

2m − (0.2)2m

Renato’s Expression:

Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:

8(m/5)

Help me with this question, please
anzhelika [568]

Answer:

Part 1: [ -4 = -8 ]

Part 2: Inconsistent

Step-by-step explanation:

<u>Part 1</u>

1. Move all terms that don't contain x to the right side:

3x - 6y+6y = -12+6y

= 3x = -12 + 6y

2. Isolate x:

\frac{3x}{3} = \frac{-12+6y}{3}

x = -4 + 2y

3. Substitute the new expression into the original:

-4 + 2y - 2y = -8

4. Simplify:

-4 + 0 = -8

[ -4 = -8 ]

<u>Part 2</u>

The two solutions are not equal in value, so, we can conclude that the system of equations has no solution, or is inconsistent.

hope this helps!

10. Use the vertical line test to determine if the graph below
klasskru [66]

The graph is a function. When drawing a vertical line, there will be two circumstances:

  1. The line intersects only one point on a graph.
  2. The line intersects more than one point on a graph ( POI > 1 )

For the first circumstance, the graph that has only one intersect with a line - it is a function. For the second circumstance, the graph cannot be a function as it gives more than one y-value for a single x-value.

The conclusion is that if a line only has one intersect on a graph then it is a function. Otherwise, not a function but a relation instead. All functions are relations, but not all relations can be functions.

Answer

  • The graph passes the vertical line test and is a function.
