Answer:
Step-by-step explanation:
For x:
8x = 18 - 2y
x = (18 - 2y)/8
For y:
2y = -8x + 18
y = -4x + 9
The equation would be: y = 100(0.7)^x
This is an example of an exponential decay equation. They are in the form of y = ab^x.
A is the starting value.
B is the rate of change. In this case, we are using 0.7 or 70% because the amount is decreasing by 30%. 100% - 30% = 70%
Answer:
1. x = 6 2. x = 9 3. x = 3
Step-by-step explanation:
Use <u>Intersecting Secants Theorem</u>:
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
1. AC and AD are secants that intersect at point A
So, AB x AC = AE x AD
x 15 = 6 x (6 + 9)
15 = 90
= 6
2. KM and KN are secants that intersect at point K
So, KL x KM = KO x KN
10 x (10 + 8) = x 20
180 = 20
= 9
3. IG and IF are secants that intersect at point I
So, IH x IG = IJ x IF
x 39 = 9 x (9 + 4)
39 = 117
= 3
Answer:
The answer to your question is below
Step-by-step explanation:
A) 2x > -6
x > -6/2
x > -3
It must be a graph with an open circle starting at -3 and then to the right.
It is the first graph.
B) x - 4 < -7
x < -7 + 4
x < -3
The graph must be an open circle starting at -3 and pointing to the left.
it is the second graph.
C) 6 + x ≤ 3
x ≤ -6 + 3
x ≤ -3
The graph must be a closed circle starting at -3 and pointing to the left.
it is the forth graph.
D) -x - 5 ≤ -2
-x ≤ -2 + 5
- x ≤ 3
x ≥ -3
The graph must be a closed circle starting at -3 and pointing to the right.
It is the third graph.
Answer:
If you multiply the amount of square inches by 5184, you'll get the number of pixels.
Step-by-step explanation:
6x5184=31,104
72x5184=373248
If you divide the number of pixels by the number of square inches, you get the answer.
