Answer:
y = -3x + 15
Step-by-step explanation:
The equation of the line parallel to the given line that contains point is:
3x + y - 15 = 0 (General form)
y = -3x + 15 (Slope y-intercept form)
Step 1: The slope of a given line is. m = -3
Step 2: Parallel lines have the same slope, so the slope of the unknown line (m1 ) will also be -3. So, the parallel line will have a slope of m1 = -3
Step 3: Now we have a point and the slope so we can use point-slope form, which is: y - y0 = m1 (x - x0)
In this example we have: m1 = -3 , x0 = 4 and y0 = 3 . After substitution we have:
y - y0= m1(x-x0)
y - 3 = -3(x - 4)
y - 3 = -3x + 12
y = -3x + 12 + 3
y = -3x + 15

I would set up a proportion:
The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals." Just cross multiply and then solve for x:
That means there are 20 kids meals sold and 16 adult meals sold, so the result is:
36 meals in total.

The domain of g(x)= 3x^2 is Real number and it's range is {y∈R / y≥0}
The domain of h(x)= -3x^2 is Real number and it's range is {y∈R / y ≤0}
The domain of a function f(x) is the set of all values for which the function is defined, and the domain of a function is the set of all values that f takes on. The domain and range are defined for a relation and are the sets of all x-coordinates and all y-coordinates of ordered pairs.
The graph of f(x)= x^2 is given
We need to find the domain and range of g(x)=3x^2 and h(x)= -3x^2
The Graph of 3x^2 is different from x^2 in terms of plotting
When ,
x= -2 g(x)=12
x=-1 g(x)=3
x=0 g(x)=0
x=1 g(x)=3
x=2 g(x)=12
The Graph of -3x^2 is different from x^2 in terms of plotting
When ,
x= -2 g(x)=-12
x=-1 g(x)= -3
