Step-by-step explanation:
Rotate the line counterclockwise 90 degrees so that it's now facing top left and bottom right and the slope is negative going down. Now reflect it to the left over the y-axis which is the straight up vertical line. Then, reflect it back to the right and rotate it 270 degrees putting it back at the beginning

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

write the set using interval notation
{x| 3 < x < 13 and x [tex]\neq[/tex] 4
Answers
Answer:
[tex]\displaystyle (3, 4) \cup (4, 13)[/tex]
Step-by-step explanation:
We are given the set:
[tex]\displaystyle \left\{ x| 3 < x < 13 \text{ and } x \neq 4\right\}[/tex]
And we want to express this in interval notation.
In words, this reads: all values of x between 3 and 13 and x does not equal 4.
Hence:
[tex]\displaystyle (3, 4) \cup (4, 13)[/tex]
We use parentheses as we do not include the values of 3 and 13 inside our interval. Likewise, since x cannot equal 4, we skip four, but use the union symbol to connect the two intervals.
[tex]\\ \sf\longmapsto \left\{x|3<x<13,x\neq 4\right\}[/tex]
The solution is
[tex]\\ \sf\longmapsto (3,4)\cup (4,13)[/tex]
Now Find all elements
[tex]\\ \sf\longmapsto \left\{5,6,7,8,9,10,11,12\right\}[/tex]

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°
Evaluate. (-9)2 = 1 (-5) = 1

Andrew Is riding his bike. He biked a distance of 14 miles at a rate of 7 mph. using the distance formula, d = rat, solve for Andrews time in MINUTES.
(9th grade Algebra 1)
Answers
d = rt ( d = distance, r = rate (speed) and t = time)
14 = 7t
Divide both sides by 7:
t = 14/7
t = 2 hours
1 hour = 60 minutes.
2 hours x 60 = 120 minutes total.
120 minutes
Step-by-step explanation:
14 divided by 7 is 2 (hours). This means that Andrew biked for 2 hours at a pace of 7mph. Two hours is equal to 120 minutes.

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.
