The graph of this system of equations is which of the following?
2x + y = 6
6x + 3y = 12
Overlapping lines
Parallel lines
Intersecting lines
A curve intersecting with a line
Answer:
From what I found, the answer is parallel
Step-by-step explanation:
not much of an explanation haha
The graph of the system of equations, 2x + y = 6 and 6x + 3y = 12 is: C. Intersecting lines
Note:
2x + y = 6 and 6x + 3y = 12 are two linear equations. Linear equations are straight lines.Graphed system of equations are always intersecting straight lines.Given that 2x + y = 6 and 6x + 3y = 12 is a system of equations, when both equations are graphed, it will give us two intersecting lines.
The coordinate of the point of intersection is the solution to the system of equations.
Therefore, the graph of the system of equations, 2x + y = 6 and 6x + 3y = 12 is: C. Intersecting lines

A kitchen supply outfit makes spoons and forks for sale. It costs the store $2 to buy the supplies needed to make a fork and $1 for the supplies to make a spoon. The store sells the forks for $4 and the spoons for $5. Last month they spent $39 on supplies and sold all the forks and spoons they made using those supplies for $93. How many forks and spoons did they make?
Given :
A kitchen supply outfit makes spoons and forks for sale. It costs the store $2 to buy the supplies needed to make a fork and $1 for the supplies to make a spoon. The store sells the forks for $4 and the spoons for $5.
Last month they spent $39 on supplies and sold all the forks and spoons they made using those supplies for $93.
To Find :
How many forks and spoons did the company make.
Solution :
Let, number of forks and spoons the company made are f and s.
For buying from the kitchen the equation is :
2f + s = 39 ....1)
For selling the equation will be :
4f + 5s = 93 ....2)
Multiplying equation 1) by 5 and subtracting equation 2) from it we get :
(10f + 5s) - ( 4f + 5s) = 195 - 93
6f = 102
f = 17 and s = 5
Therefore, the company make 17 forks and 5 spoons.

Kim and Jay live at the same time to travel 25 Miles to the beach can drive 9 miles in 2012 minutes G raft drive 10 miles in 15 minutes if they both continue with the same lady who will arrive at the beach first
Complete question :
kim and jay leave at the same time to travel 25 miles to the beach. kim drives 9 miles in 12 minutes. jay drives 10 miles in 15 minutes if they both continue at the same rate, who will arrive at the beach first?
Answer:
KIM
Step-by-step explanation:
Given that:
Distance traveled = 25 miles
Kim :
9 miles in 12 minutes
Rate = distance / time
Rate = 9 / 12 = 0.75 miles per minute
Jay:
10 miles in 15 minutes
Rate = distance / time
Rate = 10 / 15 = 0.667 miles per minute
Since Kim's rate is higher than Jay's rate, Kim will arrive at the beach faster than Jay.
0.75 > 0.667
Kim will arrive first

Real quick please. At a carnival it costs $6.54 for 3 tickets. Write an equation that can be used to express the relationship between the total cost (t) and the number of tickets(n) you buy.
Answer:
t=2.18n

The value of the function f(x) is 600 when x=0 and decreases by 9% for every one-unit increase in x. Complete the equation that represents the function f(x)
(If you could explain how that'd be great but you don't have to)
Answer:
f(x) = 600*0.91^xStep-by-step explanation:
Decrease by 9% is:
600 - 0.09*600 = 600*(1 - 0.09) = 600*0.91For each following term the previous term decreases by 9% and it is equivalent of multiplying by 0.91
So the function is exponential:
f(x) = 600*0.91^xAnswer:

Graph Data ALG 2 Please Help!
Answer:
1. Figure 3
2. 2881.4 cm³
Step-by-step explanation:
The graph in figure 3 has a curve that fits the data best because it captures most of the points unlike the other two curves.
The curve in figure 3 has the equation;
[tex]y=-16.9x^2 +430x+523[/tex]
2.
When using x=8, substitute the value of x in the equation with 8 to get
y = -16.9*64 + 430*8 + 523
y= 2881.4
= 2881.4 cm³
Exercises 18-20: In each of these problems, an
equation and one of its roots are given. Find:
a the value of k
b the second root
18.5 is a root of x^2- 7x + k = 0
19. 5 is the root of x^2-3x+k=0
20.7 is the root of x^2-3x= -k
Please help! It’s three questions
Answer:
(18) a. The value of k is 10.
b. The second root is 2.
(19) a. The value of k is -10.
b. The second root is -2.
(20) a. The value of k is -28.
b. The second root is -4.
Step-by-step explanation
18. One of the roots is 5, :. x = 5
Substitute x = 5 into the quadratic equation to obtain the value of k.
x² - 7x + k = 0
5² - 7(5) + k = 0
25 - 35 + k = 0
-10 + k = 0
k = 0 + 10 = 10
Factorise the quadratic equation to obtain the value of the second root.
x² - 7x + 10 = 0
x² - 5x - 2x + 10 = 0
(x² - 5x) - (2x + 10) = 0
x(x - 5) -2(x - 5) = 0
(x - 5)(x - 2) = 0
x = 5 or 2
The second root is 2.
19. One of the roots is 5, :. x = 5
Substitute x = 5 into the quadratic equation to obtain the value of k.
x² - 3x + k = 0
5² - 3(5) + k = 0
25 - 15 + k = 0
10 + k = 0
k = 0 - 10 = -10
Factorise the quadratic equation to obtain the value of the second root.
x² - 3x + (-10) = 0
x² - 3x - 10 = 0
x² - 5x + 2x - 10 = 0
(x² - 5x) + (2x - 10) = 0
x(x - 5) +2(x - 5) = 0
(x - 5)(x + 2) = 0
x = 5 or -2
The second root is -2.
20. One of the roots is 7, :. x = 7
Substitute the value of x into the quadratic equation to obtain the value of k.
x² - 3x = -k
7² - 3(7) = -k
49 - 21 = -k
28 = -k
k = -28
Factorise the quadratic equation to obtain the value of the second root.
x² - 3x = -k
x² - 3x = 28
x² - 3x - 28 = 0
x² - 7x + 4x - 28 = 0
(x² - 7x) + (4x - 28) = 0
x(x - 7) +4(x - 7) = 0
(x - 7)(x + 4) = 0
x = 7 or -4
The second root is -4.

(85, 105)
(80, 104)
(96, 72)
Answer:
(40,96)
Step-by-step explanation:
got it right on edge
The coordinate of P is ( 40 , 96) , Option A is the correct answer.
What are Coordinates ?Coordinates helps in determination of the position of an object on an x-y plane.
It can be seen form the figure the coordinates of K and J
K ( 160 ,120) & J (-40 , 80)
The coordinates of P can be determined as
[tex]\rm x = \dfrac{m}{m+n} ( x_2 -x_1) + x_1\\\\y = \dfrac{m}{m+n}(y_2 - y_1) + y_1[/tex]
Therefore ,
as the P point divides the line into Three-fifths of the length ,
KP = (3/5)KJ
JP = (2/5) KJ
which gives the ratio as 3: 2
m :n = 3 :2
x = (3/5) (-40 -160) + (160)
x = 40
y = ( 3/5)(-40) +120
y = 96
Therefore the coordinate of P is ( 40 , 96) , Option A is the correct answer.

Dave walked to his friends house at a rate of 4 mph and returned biking at a rate of 10 mph. If it took him 18 minutes longer to walk than bike, what was the total distance of the round trip?
Answer:
The total distance of the round trip was 4 miles
Step-by-step explanation:
1. Let's check all the information given to answer the question correctly:
Speed of Dave walking to his friend's house = 4 mph
Speed of Dave biking from his friend's house = 10 mph
Time walking is 18 minutes longer than time biking
2. What was the total distance of the round trip?
Time walking = x
Time biking = x - 18
For solving x, we will use the following equation:
4x = 10 * (x - 18)
4x = 10x - 180
-6x = - 180
x = -180/-6 (Dividing by - 6)
x = 30
Dave walked 30 minutes and biked 12 minutes, now we can calculate the total distance, this way:
30 minutes = 0.5 hours and 12 minutes = 0.2 hours
Total distance = 4 *0.5 + 10 * 0.2
Total distance = 2 + 2
Total distance = 4 miles.
Answer:
4 miles is the answer

The first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 15 in. How long is the third side?
If s represents the length of the second side, which of the following represents the length of the third side?
Answer:
[tex]\boxed{\frac{23}{3} ~in}[/tex] or [tex]\boxed{7,7~in}[/tex]
.
Step-by-step explanation:
Suppose, the first side is a, the second side is b, and the third side is c. So:
→ a = s - 4
→ b = s
→ c = (s - 4) + 3
→ a + b + c = 15
First step, find the value of s
a + b + c = 15
(s - 4) + s + (s - 4) + 3 = 15
3s - 5 = 15
3s = 15 + 5
3s = 20
[tex]s = \frac{20}{3}[/tex]
So, the third side is
c = (s - 3) + 4
c = s + 1
c = [tex]\frac{20}{3} + 1[/tex]
[tex]c = \frac{23}{3}[/tex]
