Answer:
x-intercept equals 10
interpretation is that, after 10 hours, all of the snow will be melted
Step-by-step explanation:
The linear equation can be used to solve to get the value of unknown quantities. The x-intercept of the equation is 10 and its interpretation in the context of the problem is that it shows zero depth at t = 10.
What is a Linear equation?A linear equation is a equation that has degree as one.
To find the solution of n unknown quantities n number of equations with n number of variables are required.
The given equation for the depth of the snow is as below,
S = -2t + 20
Here, S is the depth at a time t.
Suppose S is on y-axis and t on the x-axis.
Since the x-intercept of an equation is found by Substituting y = 0.
Substitute S = 0 in the given equation to get,
0 = -2t + 20
=> 2t = 20
=> t = 10
It means at t = 20, the depth of snow will become zero.
Hence, the x-intercept for the given case is 10 and it shows zero depth of the snow.

Help find slope, y intercept, rise/run, and function
Answer:
y = -3/2 + 7
Step-by-step explanation:
The line crosses the y-axis at 7. Meaning b is 7. the line goes down by 3 and to the right by 2, so the slope is -3/2
Solve the following system of equations using the substitution method
y - 3x = 12
y = - 3
Answer:
x = 5
y = -3
as an ordered pair: (5,-3)
Step-by-step explanation:
if y = -3, then replace y in the first equation with -3.
-3 - 3x = 12
move -3 over to the other side by adding 3 to both sides.
3x = 15
x = 5
y = -3
Answer:
x = -5
y = -3
Step-by-step explanation:
Two equations
Solve using substitutition
y = -3
y - 3x = 12
_____________________
Since the first equation has y alone, we can plug it into the second equation for y.
(-3) - 3x = 12
-3 - 3x = 12
Add 3 to both sides :
-3x = 15
Divide -3 from both sides to get x alone :
x = -5
Now that we have x, plug it into x in the second equation :
y - 3(-5) = 12
y + 15 = 12
Solve for y :
Subtract 15 from both sides :
y = -3

f(x) = —x^2 – 3x
Find f(10)
Step-by-step explanation:
f(x) = —x^2 – 3x
f(10)={-10}²-3×10=100-30=70
Answer:
f(10) = 70
Step-by-step explanation:
In this question, plug in "10" to "x" and solve.
Solve:
f(10) = -(10)^2 - 3(10)
f(10) = 100 - 3(10)
f(10) = 100 - 30
f(10) = 70
Your final answer would be f(10) = 70

Answer:
Alternate Interior ∠s: 3 & 5, 4 & 6.
Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.
Alternate Exterior ∠s: 1 & 8, 2 & 7.
Consecutive ∠s: 3 & 6, 4 & 5.
Step-by-step explanation:
Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.
Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.
Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.
Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.
Good luck.

On a scale drawing,1 in represents 8 feet. What is the actual length of a room that measures 3.4 inches
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2

A triangle has side lengths of 23 in, 6 in, and 28 in. classify it as acute right or obtuse
Answer:
In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.
Step-by-step explanation:
if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.
if c^(2 )< a^(2)+b^(2) then the triangle is acute.
if c^(2 )= a^(2)+b^(2) then the triangle is right

A group of students are going on a field trip. if the group takes 3 vans and 1 car, 22 students can be transported. if the group takes 2 vans and 4 cars, 28 students can be transported. write and solve a system of equations to represent the situation. fill in the blanks to indicate the number if students that can fit in each van and car?
Answer:
6 students.
Step-by-step explanation:
3v + c = 22 ---> c = 22 - 3v
2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28
2v + 88 - 12v = 28
-10v + 88 = 28
- 88 - 88
- 10v = - 60
v = 6 students
