Answer:
y=9-2x
Step-by-step explanation:
The equation that shows the relationship between the number of hours since Emmy went to bed is y = -2x + 9.
A linear equation is given by:
y = mx + b;
m is the rate of change, b is the initial value of y and y,x are variables.
Let x represent the number of hours since Emmy went to bed and y the temperature in °F. Since temperature has been dropping 2°F each hour, m = -2. Also b = 9°F, Hence:
y = -2x + 9
The equation that shows the relationship between the number of hours since Emmy went to bed is y = -2x + 9.

Joan can't quite read the board in her math class. She writes down the equation she reads on the
board as 3x – 7 = 38. She correctly solves the equation she wrote down, but is surprised to hear the
teacher say the answer is 6 less than the answer she found. When she asks the teacher to check her
work, the teacher says that Joan copied the coefficient of x incorrectly (but copied everything else
correctly). What should the coefficient of x have been?
Answer:
x = 15
Step-by-step explanation:
3x - 7 =38
3x = 38+7
3x = 45/3
x = 15
The correct coefficient of x is 5 and the correct equation is 5x-7=38.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 3x-7=38.
Solution to given equation is
3x=38+7
3x=45
x=15
The teacher say the answer is 6 less than the answer she found.
Which is x=9
The teacher says that Joan copied the coefficient of x incorrectly
If equation is 5x-7=38
5(9)-7=38
38=38
Therefore, the correct coefficient of x is 5 and the correct equation is 5x-7=38.

If m<18 = 46° and m<13 = 69°, calculate m<10.
Answer:
m<10 = 65°
Step-by-step explanation:
I. Given m<18 = 46deg, m<13 = 69deg and m<10 = x
The degree is less than 90deg, so this triangle is acute triangle.
Sum of degree inside of triangle is 180°
So 46 + 69
= 115
Find x by
180 - 115 = 65
So m<10 = 65°

Use the figure below to answer the following questions.
What is m∠1?
60
30
90
120
Answer:
30
Step-by-step explanation:
1. The exterior angle theorem states that the two opposing (in terms of the exterior angle) interior angles of a triangle are congruent to the exterior angle. This means that m∠1 (x) + 90 = 120. Now, we just have to solve for x.
2. (Solving)
Step 1: Subtract 90 from both sides.
[tex]x + 90 = 120[/tex] [tex]x - 90 = 120 - 90[/tex] [tex]x = 30[/tex]Step 2: Check if solution is correct.
[tex]30 + 90 = 120[/tex] [tex]120 = 120[/tex]Therefore, m∠1 = 30 degrees.
Answer:
∠ 1 = 30°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is the exterior angle of the left triangle , then
∠ 1 + 90° = 120° ( subtract 90° from both sides )
∠ 1 = 30°
