Answer:
0.33333
Step-by-step explanation:
For the small tables, it will be 6X, because since they fit 6 people, you will need to multiply 6 times the amount of tables(which is X), then for the larger table, it will be 10Y, because since they fit 10 people, you will multiply 10 times the amount of tables (which is Y).
This leaves you with 6X+10Y
If they are expecting AT LEAST 150, then the equation needs to be set to greater than or equal to 150, but if they are expecting exactly 150, no more no less, then the equation will be set equal to 150.
Therefore it is either:
A: 6X+10Y>or=150
B:6X+10Y=150
Answer:
(-4,-2) and (-2, -2)
Step-by-step explanation:
Eliminate y by equating the two given equations:
y=-x^2-6x-10
y = 3x^2 + 18x + 22 = -x^2 - 6x - 10.
Next, combine like terms, obtaining: 4x^2 + 24x + 32 = 0
Simplify by dividing all terms by 4: x^2 + 6x + 8 = 0.
Factor:
x^2 + 6x + 8 = 0 => (x + 4)(x + 2) = 0.
Solve for x: x = -4 and x = -2.
Find the y-values associated with these x-values:
y = -(-4)^2 - 6(-4) - 10 = -16 + 24 - 10 = -2, so that one solution is (-4,-2)
y = -(-2)^2 - 6(-2) - 10 = -4 + 12 - 10 = -2, so that the other sol'n is (-2, -2).
Answer:
100
Step-by-step explanation:
theres two sets of numbers that multiply to 4
1 times 4 and 2 times 2
to find the area use one of the sets as the length and width of the shape and multiply it by 5
for example 1 times 5 equals 5 and 4 times 5 equals 20
then u multiply 5 times 20 to get the area of the new shape which is 100
