I think the answer is substitution property of equality because you are substituting 9 for y as y=9.
Answer:
y = log(x + 1)
Step-by-step explanation:
Given graph represents a logarithmic graph.
Let the equation of the graph is represented by the logarithmic graph,
y = log(x + b)
This graph passes through origin (0, 0),
For the given point (0, 0),
0 = log(0 + b)
log(1) = log(b)
b = 1
Therefore, the function that corresponds the graph will be,
y = log(x + 1)
Answer:
∠7 = 95°
Step-by-step explanation:
∠1 and ∠4 are vertical angles so they are equal.
so:
3x + 10 = 4x - 15
simplify:
x = 25°
∠4 = 4(25) - 15 = 85°
∠8 = ∠4 because they are corresponding angles
∠7 = 180° - 85° = 95° because they are supplementary angles (add together to = 180°)
