Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D
Step-by-step explanation:
The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where
a is the altitude measured in feet
T(a) is the boiling point of water in degree
The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)
By comparing between the form of the function and the given function
∴ m = -0.0018 ⇒ degrees per foot
∵ The sign of the slope is negative
∵ The slope = Δf(x)/Δx
- That means T(a) is decreasing function
∴ The boiling point is decreases when the altitude increasing
∵ -0.0018 = degrees per feet
∴ The boiling point decreases by 18 degrees as the altitude
increases by 10,000 feet or the boiling point decreases by 1.8
degrees as the altitude increases by 1,000 feet
The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

Answer −9
x + 1 = −80
Brainlist included
Answer:
x=9
Step-by-step explanation:
-9x+1=-80
To eliminate the one, you subtract one from both sides.
That gives you:
-9x=-81
Then you divide both sides by negative nine to get x by itself.
x=9
The difference of six times a number and seven results in 35.
Identify the steps necessary to solve the equation.
Answer:
Let the number be x
According to the question,
6x -7 = 35
=> 6x = 35 + 7
=> x = 42/6
=> x = 7
The solution to the equation is x = 7.
We have,
Let's assume the unknown number is represented by the variable 'x'.
- Translate the given information into an equation:
6x - 7 = 35.
- To isolate the variable 'x', start by adding 7 to both sides of the equation:
6x - 7 + 7 = 35 + 7.
- Simplify:
6x = 42.
- Next, divide both sides of the equation by 6 to solve for 'x':
(6x)/6 = 42/6.
x = 7
Therefore,
The solution to the equation is x = 7.

Two similar triangles are shown below:
Which two sets of angles are corresponding angles?
∠e and ∠h; ∠f and ∠g
∠e and ∠i; ∠f and ∠h
∠e and ∠g; ∠f and ∠h
∠e and ∠i; ∠f and ∠g
Answer:
im pretty sure the answer is ∠e and ∠i; ∠f and ∠g
but if not im so sorry :(
Answer:
The third answer
Step-by-step explanation:
Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the same speed?
Answer:
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour
They did not run at same speed
Step-by-step explanation:
formula of speed = distance covered/ time taken
For Andre
Distance = 2 KM
time = 15 mins
60 mins = 1 hour
15 mins = 1/60 * 15 hour = 0.25 hours
thus,
speed = 2km/0.25 hour = 8 km per hour
Similarly for Jada
Distance = 3 KM
time = 20 mins
60 mins = 1 hour
20 mins = 1/60 * 20 hour = 1/3 hours
thus,
speed = 2km/(1/3)hour = 6 km per hour
Now we have
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour

Which equation represents the line that passes through (–6, 7) and (–3, 6)?
y = –y equals negative StartFraction one-third EndFraction x plus 5.x + 9
y = –y equals negative StartFraction one-third EndFraction x plus 5.x + 5
y = –3x – 11y
y = –3x + 25
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)
m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 6 ), then
6 = 1 + c ⇒ c = 6 - 1 = 5
y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

Which graph represents the function f(x) = –|x + 3|?
Answer:
Step-by-step explanation:
f(x) = –|x + 3| is a case of the absolute value function
f(x) = -|x - {a}| + c, where (a, c) is the vertex. Comparing them, we see that
the value of a must be -3 and that of c must be 0.
Thus, the vertex of the graph is at (-3, 0), and the graph opens up; it looks like a "v" shape.

A)
8n – 4
C)
4(8 + n)
B)
8n + 4
D)
(8 + n) – 4
Answer: B
Step-by-step explanation:
4 more than the product of 8 and n is represented as 8n + 4 because:
4 more means add 4 to it.
We see that option B gives up 8n + 4.
The expression in words is 4 more than the product of 8n.
The answer is B.
Answer:
8n + 4
Step-by-step explanation:
Product of 8 and n : 8*n = 8n
4 more than the product of 8 and n means 4 should be added to 8n
8n + 4
Micah is shopping for work shirts. The short-sleeve shirts cost $18 each and the long-sleeve shirts cost $24 each. He wants to buy 2 more short-sleeve shirts than long-sleeve shirts, and he is willing to spend no more than $120 total. How many long-sleeve shirts can he buy?
Answer:
2
Step-by-step explanation:
18 + 18 = 36
36 + 24 = 60
60 + 18 = 78
78 + 24 = 102
102 + 18 = 120
There are two total long-sleeve shirts and four total short-sleeve shirts.

Help!!!! Having trouble finding the answer any help would be good
Answer: The slope is 3/2 or 1.5
Step-by-step explanation:
The line is going through the origin meaning that the slope will be the coordinate of one of the points divided by its y coordinate.
One point that can be found on the line is (2,3)
Divide the y coordinate by the x coordinate to find the slope.
The y coordinate is 3 and the x coordinate is 2.
3/2 = 1.5
The slope is 3/2 or 1.5.

• commutative property
• addition property of equality
• 2x=8
• distributive property
• division property of equality
• x=4
• multiplication property of equality
• subtraction property of equality
Answer:
See below
Step-by-step explanation:
[tex]2(x+5)-3 =15[/tex]
Using the distributive property in the LHS we get
[tex]2x+10-3 =15[/tex]
[tex]2x+7=15[/tex]
Now add -7 both sides. So we have the subtraction property of equality.
[tex]2x+7+(-7)=15+(-7) \text{ This is what I meant for add}[/tex]
[tex]2x+7-7=15-7[/tex]
[tex]2x=8[/tex]
Now divide both sides by 2. So we have the division property of equality
[tex]\dfrac{2x}{2} =\dfrac{8}{2}[/tex]
[tex]x=4[/tex]
