Go to your math tools and open the Graph tool to graph Gwen’s and Keith’s equations. Be sure to remove Tristan’s equation before adding Keith’s equation.
Do the two lines intersect? Why or why not? What does this mean in terms of the situation? If they intersect, at what point do they intersect and what does this point mean in terms of the situation?
gwen’s: y = 100 + 10x
keith's: y = 10x
The lines will never intersecting as they are parallel lines because the slope of the lines is equal.
Given that,
y = 100 + 10x and y = 10x
To justify whether the two lines intersect each other or not,
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
y = 10 + 10x,
The slope of the equation is m1 = 10
y = 10
The slope of the above equation is m2 = 10
Since the slope of both lines is an equation, it implies that the lines are parallel to each other it will not intersect at any point.
Thus, the lines will never intersect as they are parallel lines because the slope of the lines is equal.

ok so i need you to tell me how many solutions does this problem have but if none then say no solution but 3(x + 4) = 3x + 4
Answer:
-8
Step-by-step explanation:
3( x + 4 ) = 3 x + 4 = 3 x + 4
3 x + 12 = 3 x + 4
3x + 12=3x + 4
3x + 12-12 = 3x + 4-12

Solve the word problem using a proportion: If 4 dogs eat 6 cups of dog food every day, how much food would be needed for 6 dogs?
Thank you so much
And could you maybe explain in good detail because i want to be able to do the other problems myself. ;3;
Answer:
ill try my best it's been 4 years since I learned this
Step-by-step explanation:
The answer is 9 because each dog is eating 1.5 or 1 1/2 cups of dog food to get the 1.5 or 1 1/2 you must divide 6 by 4.
Now take that 1 1/2 and multiply it by 2 since where adding two dogs that equals 3
3 + 6 =9

144 students enter a spell bee, but only 1/6 of the group will make into the semi-final round, and only 2/3?that group will make into the final round. How many students will enter the final round of the spelling bee?
A8
B16
C24
D36
Answer:
The answer is B.
Step-by-step explanation:
We want 1/6 of 144, so we divide 144/6=24 students.
Then, only 2/3 of those 24 students will make it to the final round. So, we want to know how many students are in three (2/3) groups and we want two (2/3) of those groups. So, we divide those 24 students by 3 to know each group has 8 students and then we want 2 of those groups (remember 2/3), so we multiply 2x8=16 students in the final round.
Kala will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $47.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $51.98 and costs an additional $0.12 per mile driven. How many miles would Kala need to drive for the two plans to cost the same?
Answer:
200 Miles
Step-by-step explanation:
Solving:
47.98+.14x=51.98+.12x
.14x=4+.12x
.02x=4
x=200
Checking:
47.98+.14(200)
75.98
51.98+.12(200)
75.98

Which equation has every number as a solution? *
4x = 4x + 1
4x + 1 = 4x - 1
4(x + 1) = 4x + 1
4(x + 1) = 4x + 4
PLEASE HELPPPP 10 pointsss
Answer:
the last equation has a solution
Step-by-step explanation:
4(x+1)=4x+4 which gives
(4*x)+(4*1)=4x+4
4x + 4 = 4x + 4
Therefore both the left-hand side and the right-hand side are equal

Write the ratio 2 : 12 in the two other forms. (the word “to” and fraction form)
Read the choices carefully. The “to” and the fraction form should be the same
Answer:
2 to 12 as a phrase, and 2/12 or 1/6 as a fraction
Step-by-step explanation:
The ratio 2 : 12 in the other two forms can be written as 2 to 12 and 2/12 in fractional form.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
The given ratio is defined as 2 : 12
Now we have to write this in two forms. Fractional form and in another form.
2 : 12 can be written as 2 to 12 in words.
In fractional form, we can write this as,
2 : 12 = 2/12 = 1/2
So 1/6 is also a way of writing 2 /12
Hence the two forms are 2 to 12 and 2/12 in fractional form.

The value of a car decreases by 20 percent per year. Mr. Sing purchases a $22,000 automobile. What is the value of the car at the end of the second year?
A- $14,080
B- $17,600
C- $19,800
D- $26,400
Answer:A
Step-by-step explanation:cause if you know a lot about cars you would know
Answer:
A- $14,080
Step-by-step explanation:
At end of first year:
$22,000 will decrease by 20%. It means to subtract 20% of 22,000 from 22,000.
20% of 22,000 is
0.2 x 22,000 = 4,400
Now,
22,000 - 4,400 = 17,600
At end of second year:
$17,600 will decrease by 20%. It means to subtract 20% of 17,600 from 17,600.
20% of 17,600 is
0.2 x 17,600 = 3520
Now,
17,600 - 3,520 = 14,080
Hence, $14,080 is the value of the car at the end of 2 years.
