Answer: YZ = 13
Point Y is between the points X and Z => XY + YZ = XZ
=> 3x - 4 + 2x + 3 = 24
<=> 5x - 1 = 24
<=> x = (24 + 1) : 5 = 5
with x = 5 => YZ = 2.5 + 3 = 13

Answer:
0.477121=−log(3x+7)+0.30103
Step 1: Flip the equation.
−log(3x+7)+0.30103=0.477121
Step 2: Add -0.30103 to both sides.
−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103
−log(3x+7)=0.176091
Step 3: Divide both sides by -1.
log(3x+7)=−0.176091
Step 4: Solve Logarithm.
log(3x+7)=−0.176091
10log(3x+7)=10−0.176091
3x+7=0.666667
3x+7−7=0.666667−7(Subtract 7 from both sides)
3x=−6.333333
3x
3
=
−6.333333
3
(Divide both sides by 3)
x=−2.111111

Answer:
-3
Step-by-step explanation:
5x³ + 2 , when x = -1
5(-1)³ + 2
= -5 + 2
= -3
