Proportions- determine if each pair of ratios forms a proportion. show all work! 12/15 and 2/3

They do not form a proportion.

Step-by-step explanation:

To determine if they are a proportion, you can cross multiply and get the same answer on both sides. So, we multiply the numerator from the first by the denominator in the second.

12 * 3 = 36

Now we use the denominator from the first side and the numerator on the second side.

15 * 2 = 30

Since they are not equal, it is not a real proportion.

you do cross-multiply:

10.2(12)= 122.4

4(h)=4h

4h=122.4

h=30.6

if h is 30.6, it will be proportional

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
