Answer:Find an answer to your question Which number line shows the solution set for in-3155? -8 -6 -4 -2 0 2 4 6 8 -8 -6 -4 -2 0 2 4 6 8 8 6 o -8
Step-by-step explanation:
Answer:
x > 4
Step-by-step explanation:
Given
2(x + 6) < 3x + 8 ← distribute left side
2x + 12 < 3x + 8 ( subtract 3x from both sides )
- x + 12 < 8 ( subtract 12 from both sides )
- x < - 4
Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.
x > 4
Answer:
Step-by-step explanation:
797.2
Step-by-step explanation:
secants originating from the same point have the same relative length relationship :
outside part × sum of outside and inside parts
is the same for every secant from the same point.
so,
5×(7+5) = 6×(2x-8+6) = 12x - 12
60 = 12x - 12
12x = 72
x = 6
WV = 2x - 8 = 2×6 - 8 = 12 - 8 = 4
so, B is correct.
A geometric sequence is a sequence in which there is a common ratio between any two consecutive terms. In this case if X:Y:Z are in the ratio of 2:7:8 the multiplying by a constant k, we have X=2k, Y= 7k and Z=8k.
Then if X, Y-12, Z form a Geometric sequence, it means X/Y-12=Y-12/Z which is the same as 2k/7k-12=7k-12/8k if we cross multply, we get
16k²= 49k²-168k +144
33k²-168k+144 =0 solving for k
k = 4 or 1.091 if we take the whole number to find the values of X,Y and z,
X= 8, Y= 28 and Z=32
