Help! Ratios and Porportions

Mathematics
1 answer:
SOVA2 [1]3 years ago
7 0
We learned that ratios are value comparisons, and proportions are equal ratios. Ratios can be written with colons or as fractions. So, to compare the number of girls to boys in a litter of puppies, we can write 2:4 or 2/4 to say that there are two girls to four boys.

F(x) = 8|x| - 5<br> f(-2) =
Anastaziya [24]

Answer:

f(-2) = 11

Step-by-step explanation:

Hello!

We can evaluate y by plugging in -2 for x in the equation.

<h3>Evaluate</h3>
  • f(x) = 8|x| - 5
  • f(-2) = 8|-2| - 5
  • f(-2) = 8(2) - 5         Remember that absolute value turns the number positive
  • f(-2) = 16 - 5
  • f(-2) = 11

The evaluated value is 11.

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Helga [31]

Answer: (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

Step-by-step explanation:

Point slope form: (y-b)=n(x-a) , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through (x_1,y_1) and (x_2,y_2) :-

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

So, the equivalent equations are :

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)
