No, because 5/8=15/24 and 15/24≠15/40

15/40 = 5/8
cross multiply
(15)(8) = (40)(5)
120 = 200...incorrect...so it is not a true proportion

little tip : proportions are nothing but equivalent fractions...15/40 is not equivalent to 5/8.....now if it would have been 15/40 = 3/8 , since these are equivalent fractions, this would have been a true proportion

After Noam transformed the graph of the function f (x)= |x|, the graph's vertex became (0,48), Which sequences of transformation

Pachacha [2.7K]

Answer:

f(x) = |x|+48 would make the vertex be (0,48)

Step-by-step explanation:

Since the y-coordinate changed, this means that only vertical shift could have occured. Therefore, 48 must've been added to |x|.

type the correct answer in the Box. Use Roman numerals instead of words. The graphs of functions f and g are shown. Function g i

marysya [2.9K]

Answer:

k = 2

Step-by-step explanation:

<u>Take some reference points on the graph of f and g:</u>

f(2) = 1, g(2) = 2
f(4) = 2, g(4) = 4
f(8) = 4, g(8) = 8

<u>According to the numbers above we can state:</u>

g(x) = 2f(x)

So the value of k is 2

1.) Which domain restrictions apply to the rational expression? 14x-2x / x^2-7x

mezya [45]

Answer:

3. $\displaystyle 1\frac{1}{3} = x$

2<em>C.</em> $\displaystyle III.$

2<em>B.</em> $\displaystyle I.$

2<em>A.</em> $\displaystyle II.$

1. $\displaystyle Set-Builder\:Notation: [x|7, 0 ≠ x] \\ Interval\:Notation: (-∞, 0) ∪ (0, 7) ∪ (7, ∞)$

Step-by-step explanation:

3. <em>See</em><em> </em><em>above</em>.

2<em>C</em>. The keyword is ratio, which signifies division, so you would choose "III.".

2<em>B</em>. The keyword is percent, which signifies multiplication of a ratio by 100, so you would choose "I.".

2<em>A</em>. The keyword is total, which signifies addition, so you would choose "II.".

1. Base this off of the denominator. Knowing that the denominator CANNOT be zero, you will get this:

$\displaystyle x^2 - 7x \\ x[x - 7] = 0; 7, 0 = x \\ \\ Set-Builder\:Notation: [x|7, 0 ≠ x] \\ Interval\:Notation: (-∞, 0) ∪ (0, 7) ∪ (7, ∞)$
