Explain why 4:6 and 8: 10 are not<br> equivalent ratios.

andrew11 [14]

Answer:

Because when 4:6 is simplified, you get 2:3, but when 8:10 is simplified, you get 4:5

So, they are not equivalent ratios because their simplified ratios are not the same.

Step-by-step explanation:

Hope this is helpful.

What’s the answer. Picture is attached

y > -(1/2) x + 5 and y ≤ 3x - 2

(5,3):

3 >? -(1/2)(5) + 5 = 5-5/2 = 5/2; that's true

3 ≤ 3(5) - 2 = 13; that's true

(4,3)

3 >? -(1/2)4 +5 = 5 - 2 = 3; that's false

Answer: 2) (4,3)

Let's check the rest.

(3,4)

4 >? -(1/2)(3) + 5 = 5 - 3/2 = 7/2, true

4 ≤ 3(3) - 2 = 7, true

(4,4)

4 >? -(1/2)(4) + 5 = 5 - 2= 3, true

4 ≤ 3(4) - 2 = 10, true

Answer seems right.

What is the inverse of the function f(x) = 2x + 1?

Mazyrski [523]

Answer:

The first choice $hx = \frac{1}{2}x - \frac{1}{2}$

Step-by-step explanation:

Inverse functions are when you switch the y and x

btw f(x) is the same as y

y = 2x + 1

becomes

x = 2y + 1

solve it :)

subtract 1 from both sides

x - 1 = 2y

divide 2 from both sides

$\frac{x-1}{2}$

same as

$\frac{1}{2}x - \frac{1}{2}$

so ya know it's the first choice
