Answer:
-14/3
Step-by-step explanation:
Use derivative = 0 to find turning point(S)
D f(x) = 3x + 10 = 0
3x = - 10
X = - 10/3
When X = - 10/3
F(x) = 1.5(10/3)^2 - 10(10/3) + 12
= (3*10*10) / (2*3*3) - 100/3 +12
= 50/3 - 100/3 + 36/3
= - 14/3
Answer:
x = 16
Step-by-step explanation:
multiply all terms in the equation by the lowest common multiple of 10 and 5, that is 10 to eliminate the fractions
x - 10 = 6 ( add 10 to both sides )
x = 16
Answer:
50 + 3x ≥ 100
Step-by-step explanation:
You already know that you are getting $50 that week. Then, for every sale you make $3. Your goal is $100, but you wouldn't complain about making more. Therefore, the inequality sign used here should be the greater than or equal to sign (≥). Your equation should be what is written above, with your payment on the left and earning goal on the right of the inequality sign.
Answer:
A = 4 units ^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 4) (2)
A = 4 units ^2
