Answer:
(7x-1)(x-3)
Step-by-step explanation:
7x^2 - 22x + 3
The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.
(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3
Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.
Answer:
4691.74
Step-by-step explanation:
A = P(1 + r/n)^nt
= 2300(1 + .08/4)^(4 * 9)
= 2300(1.02)³⁶
= 2300 * 2.039887
= 4691.74
Answer:
Step-by-step explanation:
3/18 + (-14/18)= -11/18
Answer:
Adult ticket is $6
Student ticket is $4, as you said.
Step-by-step explanation:
We'll call adult tickets x and student tix y.
14x + 11y = 128
14x + y = 88
First, solve the second equation for y in terms of x:
y = 88- 14x
Then substitute that for y into the first equation:
14x + 11(88-14x) = 128
14x + 968 - 154x = 128
-140x = -840
x = 6 The adult ticket is $6, like you said.
Now take that and solve for y:
y = 88 - 14(6)
y = 88 - 84
y = 4 The student ticket is $4, as you said.
