Answer: y-intercept = (0, -18)
Step-by-step explanation:
This is a quadratic equation question, where the quadratic equation is in the standard form of [y = ax² + bx + c]
The function of [a] in the equation is to determine the maximum/minimum of the parabola. If [a] is positive, then the parabola opens upward, which is a minimum. If [a] is negative, then the parabola opens downward, which is a maximum.
There aren't any particular functions of [b], but it operates with [a] to find the axis of symmetry.
The function of [c] is the y-intercept. The easiest way to prove this is to let x be zero, then we are left with the value [c]
<u>Solve:</u>
Given: y=-x²+8x-18
a = -1
b = 8
c = -18
Therefore, the y-intercept is (0, -18)

Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
Answer:
104
Step-by-step explanation:
you have to find the least common multiple lcm between the bottom numbers. and since there is none before you just multiply the two together to get the same bottom number.
Answer:
D
Step-by-step explanation
you see 6 squrs and One whole.
Set up conversion problems so that you can cancel out units that you don't want and introduce units that you do want for your final solution.
5w(m/3w)=15m
So you will need 15 cups of milk if 5 cups of water are used.
