Match each value to what it represents.
Serhud [2]

Answer:

Step-by-step explanation:

(5^3/2)^-2/3 = 0.2 ⇒ E

(256^0.5)^1.25 = 32 ⇒ C

(81^1/6)^3/2 = 3 ⇒ F

(1024^0.03)^20 = 64 ⇒ D

(1000^4/7)^7/3 = 10,000 ⇒ B

(49^5/2)^0.2 = 7 ⇒ A

Step-by-step explanation:

* Lets explain how to solve the problem

- If we have base x to a power n and all to the power of m then we

multiply the two powers to be one power on the base

- [(x^n)^m] = x^(nm)

* Lets solve the problem

∵

∴ (5^3/2)^-2/3 = 0.2 ⇒ E

∵

∵ 256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^8

∴

∴ (256^0.5)^1.25 = 32 ⇒ C

∵

∵ 81 = 3 × 3 × 3 × 3 = 3^4

∴

∴ (81^1/6)^3/2 = 3 ⇒ F (answer F must be 3 not 0.333)

∵

∵ 1024 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^10

∴

∴ (1024^0.03)^20 = 64 ⇒ D

∵

∵ 1000 = 10 × 10 × 10 = 10³

∴

∴ (1000^4/7)^7/3 = 10,000 ⇒ B

∵

∴ (49^5/2)^0.2 = 7 ⇒ A

How do I find the y-intercept and slope ?
VARVARA [1.3K]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b".

In the table, when x = 0, y is 0, so the y-intercept is 0

y = mx + 0    or    y = mx


To find "m", you can use the slope formula and plug in 2 points:

(0,0) and (1, 3)

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{3-0}{1-0}

m = 3


Slope: 3

y-intercept: 0

Equation: y = 3x
