Answer:
5 dollars per foot
Step-by-step explanation:
4y = - 2x + 12
y = - 2/4x + 3
The y intercept is 3
Hello!
If s(x) = x - 7 and t(x) = 4² - x + 3, find (t · s)(x) is also known as a composite function. (t · s)(x) is read as "t is composed of s", or "the composition of t and s".
(t · s)(x) = 4² -(x - 7) + 3
(t · s)(x) = 16 - x + 7 + 3
(t · s)(x) = -x + 16 + 7 + 3
(t · s)(x) = -x + 26
Therefore, (t · s)(x) = -x + 26.
Answer:
Step-by-step explanation:
Let Freda's sum = x
Donnie has 3/4 x
He spends 63 dollars. His sum is now
3/4x - 63
Now the equation looks like this
6(3/4x - 63) = x Remove the brackets
6*3/4 x - 378 =x
6 * 3/4 = 4 1/2
4 1/2 x - 378 = x Add 378 to both sides
4 1/2 x = x + 378 Subtract x from both sides
3.5 x = 378 Divide by 3.5
x = 378 /3.5
x = 108
Since x = 108, that's how much Freda had. (She spent nothing).
