Answer:
B
Step-by-step explanation:
(1 1/2,-2)
solve for x and get 1 1/2
solve for y and get -2
Answer:
3 values
Step-by-step explanation:
2x +8 <22 and 3x >9
Solve the two inequalities separately and then put them back together
2x +8 <22
Subtract 8 from each side
2x +8-8 <22 -8
2x < 14
Divide by 2
2x/2 < 14/2
x < 7
Then solve the second inequality
3x>9
Divide by 3
3x/3>9/3
x >3
Putting them back together
x>3 and x < 7
Since it has to be an integer
4,5,6 are possible choices
3 values
To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer:
g(L) = 175L - L²
Step-by-step explanation:
350 = 2(length + width)
length + width = 175
Let L be the length,
L + width = 175
width = 175 - L
Area = length × width
g(L) = L(175 - L)
g(L) = 175L - L²
