Step-by-step explanation:
I think this should be the expression
X = 14 + 50
It's a slope-intercept form where a slope = -1.5 and y-intercept = 3.
x - intercept: y = 0
Therefore we have the equation:
-1.5x + 3 = 0 |-3
-1.5x = -3 |:(-1.5)
x = 2
Answer: x-intercept = 2, y-intercept = 3
Answer:
{y | y = –7, –1, 0, 9}
Choice B is correct
Step-by-step explanation:
The range of a function y = f(x) refers to the set of y - values for all values of x for which the function is real and defined.
The set of y values from the given table is;
–7, –1, 0, 9
Therefore, the range of the given function is;
{y | y = –7, –1, 0, 9}
Answer:
1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.
2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased.
3. F = 4/R. This is inverse variation for the same reason as number 2.
4. m/n = 4. Direct variation. For the same reason as number 1.
5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.
6. R = cl/r². Joint variation.
7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r.
8. V= pir²h. Joint variation.
