Answer:
The graph of the function opens downwards.
Step-by-step explanation:
The graph opens upward if the coefficient of x^2 is higher than 0.
But, the coefficient of x^2 (-3) is less than 0.
So the graph of the function opens downwards.
Answer:
x = 48
Step-by-step explanation:
We now that supplementary angles (as is the case for a straight line) add up to 180 degrees.
3x - 12 + x = 180
4x = 192
x = 48
Answer:
Using the combination formula:
Number of combination of r object chosen from the total object i.e n is given by:

As per the statement:
4 candy bars be chosen from a store that sells 30 candy bars
Number of candy bars chosen from a store that sells 30 candy bars(r)= 4
and
Total candy bars(n) = 30
then substitute in the given formula we have;

⇒
⇒
Simplify:
⇒
therefore, 27,405 ways can 4 candy bars be chosen from a store that sells 30 candy bars
Equation 2 is a square root function, kind of like half of a sideways parabola, Equation 3 is a parabola, and 4 is a cubic function (s-shaped). This leaves Equation 1, which is a line with a slope of 2 with a y-intercept at 7. So I'd say the answer is 1.
