Answer:
$173.06
Step-by-step explanation:
Think of "her new monthly salary" as the sum of "her monthly salary plus a 6.5% increase. Multiplying "her monthly salary" by 1.065 will produce a result that includes both the original monthly salary and the increase:
1.065($162.50) = $173.06
The first one should be read as between 75 and 97 inclusive. That means you are using ≤
75 ≤ x ≤ 97 As a compound inequality this is
75 ≤ x ; x ≤ 97
The second one is just a bit harder. That's because a place in Ohio probably could go down to - 36. Again, both ends of the inequality use ≤
-36 ≤ x ≤ 20 As a compound inequality
-36 ≤ x; x ≤ 20
I'm not sure if you should be including units like 20°F. If you are, add them in.
I believe that it is A. It is the only one that makes sense. If you look at numbers 0.47 and 0.00047, the decimal point in 0.00047 is three more spaces to the left than 0.47. Hope this helps!
Vertex form formula: y = a(x-h)^2 +k, with vertex (h,k)
There are multiple ways to find the vertex. One way is to find the roots and then find the x value exactly in between them, because this parabola is symmetrical.
0 = (x - 3)(x + 2), so x = 3 and -2. The point directly in the middle is x = 1/2 = h
To find the y value of the vertex, plug in 1/2 to the equation.
(1/2)^2 - 2(1/2) + 5 = 4.25 = k
y = (x - 0.5)^2 + 4.25
Answer:
Slope = y^2 - y^1 / x^2 - x^1
Graph n1
Slope = -5 - 1 / -6 - 2
Graph n2
Slope = -5 - 3 / 3 - 5
Graph n3
Slope = 3 - 0 / -4 - 5
