Answer:
-4
Step-by-step explanation:
Given the expression
h(x) = -x^2 +4x
h(-2) = (-2)^2 + 4(-2)
h(-2) = 4 + (-8)
h(-2) = 4 - 8
h(2) = -4
Hence the value of the function when x = -2 is -4
Given:
Ratio of cow to chicken is 6:5.
The nunmber of cows is 30.
The objective is to find the number of chickens.
Consider the number of cows and chicken as 6x and 5x.
The value of <em>x</em> can be calculated as,
Now, substitute the value of <em>x</em> to find the number of chicken.
Hence, the number of chicken will be 25.
Answer:
R
Step-by-step explanation:
Apply the knowledge of CPCTC (corresponding parts of congruent triangles are congruent) to this
C and R are written last, and order is important, because they are congruent
The correct answer should be -1 and 2/3, or 4/6
We have one value, 5/6
if we subtract 1/6 from that, we get 4/6
Since we don't have a full number value, subtracting 1 from that gives us -1 and 4/6
