Answer:

Step-by-step explanation:

y = 2/5x + p

We now that passes through (–2, 4)

 2/5 × (-2) + p = 4

⇔ -4/5 + p = 4

⇔ p = 4 + 4/5

⇔ p = 20/5 + 4/5

⇔ p = 24/5

⇒ y = 2/5x + 24/5

Equation of a line is given by y - y1 = m(x - x1); where m is the slope.

y - 4 = 2/5 (x - (-2))

y - 4 = 2/5 (x + 2)

Hope this helps! :)

Hello guys can you help me with this?​
Katyanochek1 [597]

Answer:

Step-by-step explanation:

1. Title of the graph → Comparison of the Plant Growth

2. y-axis represents the height of the plants in centimeters.

3. On day 2:

   Height of plant A (plant outside) = 5.1 cm

   Height of plant B (plant near the window) = 2.25 cm

4. Plant outside shows great increase in the height.

    On day 5,

    Height of the plant outside = 6.75 cm

    Growth in height from day 2 to day 5 = 6.75 - 5.1

                                                                   = 1.65 cm

    Height of the plant near the window = 2.5 cm

    Growth in height of the plant from day 2 to day 5 = 2.5 - 2.25

                                                                                        = 0.25 cm

    Therefore, plant outside shows the great increase in height.

5. Plant near the window grew 0.25 cm in height.

(6a^-4b^2)^-2 for the ^ it is an exponent,
larisa [96]

Negative exponents work the same as positive ones, except you have to consider the inverse of the base.

So, if for example 4^3 = 64, in the same fashion you have

4^{-3} = \dfrac{1}{4^3} = \dfrac{1}{64}

So, negative exponents lead to a fraction with numerator 1 and denominator the same expression, but with positive exponent.

So, in your case, let's work with the inner parenthesis first:

6a^{-4}b^2 = 6 \dfrac{1}{a^4}b^2 = \dfrac{6b^2}{a^4}

Now, if we want to raise this to the negative two, we have

\left(\dfrac{6b^2}{a^4}\right)^{-2} = \dfrac{1}{\left(\frac{6b^2}{a^4}\right)^2}} = \dfrac{1}{\frac{36b^4}{a^8}} = \dfrac{a^8}{36b^4}
