Answer:
2/3 =8/12
Step-by-step explanation:
2/3
Multiply the top and bottom by 4 to get a denominator of 12
2/3 *4/4
8/12
2/3 =8/12
Answer:
Option C (f(x) = 
)
Step-by-step explanation:
In this question, the first step is to write the general form of the quadratic equation, which is f(x) = 
, where a, b, and c are the arbitrary constants. There are certain characteristics of the values of a, b, and c which determine the nature of the function. If a is a positive coefficient (i.e. if a>0), then the quadratic function is a minimizing function. On the other hand, a is negative (i.e. if a<0), then the quadratic function is a maximizing function. Since the latter condition is required, therefore, the first option (f(x) = 
) and the last option (f(x) = 
) are incorrect. The features of the values of b are irrelevant in this question, so that will not be discussed here. The value of c is actually the y-intercept of the quadratic equation. Since the y-intercept is 4, the correct choice for this question will be Option C (f(x) = ). In short, Option C fulfills both the criteria of the function which has a maximum and a y-intercept of 4!!!
Answer:
Step-by-step explanation:
y & xz
y = kxz
k = y/xz
When y = 90, x = 2 and z = 9
k = 90/(2×9) = 10/2
k = 5
y = 5xz
When y = 105 and z = 3
105 = 5×3x
105 = 15x
x = 105/15
x = 7
The first equations answer is x=5/2+5/6y, yeR (yeR) means that y is a real number.
