Answer:1, 4, 6
Step-by-step explanation:
Because there are different slopes and it is a linear system there must be 2 separate lines with 1 solution. Also if x=3 both of their y’s are 0 too
the answer is 7Г2÷2 (the first one)
Original-spent=left
original-36=44
add 36 to both sides
original=80
it was $80
F(x) = -(x + 8)² - 1
<span>The function (not its graph) decreases on interval [-8, ∞). It is a quadratic function in vertex form. That form makes it easy to pick out the one extremum, where x equals -8. The leading coefficient is negative, so the extremum must be a maximum. The function decreases as x increases from there. </span>
<span>Notice that I include the value -8 in the interval. The function does not have instantaneous decrease at that value, but that is not what it means for a function to be decreasing over an interval. </span>
<span>Let a and b be any two values on [-8, ∞), such that a < b. </span>
<span>-8 ≤ a < b </span>
<span>Then f(a) > f(b). Therefore, function f is decreasing on interval [-8, ∞).</span>
Answer:
-x -7
Step-by-step explanation:
(4x − 6) − (5x + 1)
Distribute the minus sign
(4x − 6) − 5x - 1
Combine like terms
4x-5x -6-1
-x -7
