Two numbers are in the ratio 3/4. If 4 is subtracted from each they are in the ratio of 5/7. Find the numbers!
frosja888 [35]

Answer:

The two numbers are 24 and 32

Step-by-step explanation:

We can use the variable x

3x : 4x, would be a ratio of 3/4

now subtract 4 from both

3x - 4 : 4x - 4 = 5/7

3x-4 / 4x-4 = 5/7

cross multiplication

7(3x - 4) = 5(4x - 4)

21x - 28 = 20x - 20

x = 8

Two numbers are;

3x, 4x

3(8), 4(8)

24, 32

24/32 = 3/4

20/28 = 5/7

A parabola has a line of symmetry x = -5. The minimum value of the quadratic function that it represents is -7. Find a possible
Semmy [17]
The standard equation of a parabola is:

(y-k) = a(x - h)² , where h and k are the coordinates of the Vertex
 
Since the vertex is ( - 5 , -7), then :

(y +7) = a (x + 5)².
It's given that the vertex is a minimum, that means the coefficient a>0 and the parabola is open upward.

Depending on the value of a (always a>0) , the equation :

y = a(x-5)² + 7 is a parabola
