The ratio would be 4:1.

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 64 and 16 is 16

Divide both terms by the GCF, 16:

64 ÷ 16 = 4

16 ÷ 16 = 1

The ratio 64 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 16 :

64 : 16 = 4 : 1

Therefore:

64 : 16 = 4 : 1

Please help me I don’t understand this
Lyrx [107]
When you're given a point and the slope of a line, it is often easiest to write its equation in point-slope form.

This is y-y_1=m(x-x_1), where (x_1,y_1) is the ordered pair for the point you are given and m is the slope.

Here, you would write y-8=-3(x-7). Then, you simplify to get to slope-intercept form, which is y = mx+b, where b is the y-intercept.

y-8=-3(x-7) \\ y=-3x+29

The correct answer is A.

If f(x) =7 +4x and g(x) =1/2 what is the value of (f/g)
saw5 [17]

Answer:

10.8

Step-by-step explanation:

To find (f/g)(5), find f(5) and (g5) then divide the values.

f(5) = 7 + 4(5) = 27

g(5) = 1/2 (5) = 2.5

27/2.5 = 10.8
