Write the equation in slope intercept form of a line with m = 3 that passes through (2,-1)
Answers
Answer:
y = 3x - 7
Step-by-step explanation:
Use the slope intercept formula [ y = mx + b ], the slope, and the point given to find the y-intercept.
-1 = 3(2) + b
-1 = 6 + b
-7 = b
Now input the values we solved for and what we are given back into the formula.

find the measure of the angle that is 12° more than two times its supplement
Answers
Answer:
56 and 124
Step-by-step explanation:
Sum of two supplementary angle = 180
Let the first angle be x
Second angle = 2x + 12
2x + 12 + x = 180
3x + 12 = 180
3x = 180 - 12
3x = 168
x = 168/3
x = 56
2x + 12
2(56) + 12
112 + 12

Given that ⊙M≅⊙N and XZ◠≅BC◠, find m∠XMZ.
Answers
Answer:
∠ XMZ = 74°
Step-by-step explanation:
Since the corresponding arcs on the 2 circles are congruent , then the central angles are congruent, that is
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Then
∠ XMZ = 3x - 7 = 3(27) - 7 = 81 - 7 = 74°

Answers
Answer:
2
Step-by-step explanation:
Look at the graph, f(4) is at 3. So what is g(3)? it is 2.
The value of function g (f (4)) is 2.
Here,
Graph of f (x) and g (x) are shown.
We have to find the value of g (f (4)).
What is Composite function?
Composition function is an operation of two functions f and g which produces a function J such that J (x) = g (f(x)).
Now,
The value of f (4) in graph is 3.
Hence,
g (f (4)) = g (3)
And, the value of g (3) is 2.
So, g (f (4)) = g (3) = 2
Hence, The value of function g (f (4)) is 2.
