Two lines, C and D. are represented by the equations given below Line C: y = x + 14 Line D: y = 3x + 2 Which of the following shows the solution to the system of equations and explains why? O 16. 20), because both lines pass through this point (6. 20), because the point does not lie on any axis (3. 11), because one of the lines passes through this point (3. 11). because the point lies between the two axes
Answer:
(6,20)
Step-by-step explanation:
plug in 6 for x and 20 for y in both equations and solve.
Line c: 20 = 6 + 14
20 = 20
Line d: 20 = 3(6) + 2
20 = 18 + 2
20 = 20

Given lines l, m and n are all parallel and cut by two transversal lines, find the value
of x.

Answer:
x = 19
Step-by-step explanation:
l, m and n are the parallel lines.
Two transversal lines are intersecting these parallel lines.
By Intercept theorem,
Lengths of intercepts between the parallel lines are proportional.
[tex]\frac{38}{8}=\frac{x}{4}[/tex]
x = [tex]\frac{4\times 38}{8}[/tex]
x = 19
Therefore, x = 19 will be the answer.

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Graph this system of equations.
1.15x + 0.65y = 8.90
x − 3y = -15
Answer:
We have the equations:
1.15x + 0.65y = 8.90
and
x − 3y = -15
First, let's write them in the slope-intercept form:
The first one will be:
y = -(1.15/0.65)*x + 8.90/0.65
The second:
y = (1/3)*x + 15/3 = (1/3)*x + 5.
then our system is:
y = -(1.15/0.65)*x + 8.90/0.65
y = (1/3)*x + 5.
To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.
For example with the second line:
y(0) = (1/3)*0 + 5 = 5
then we have the point (0,5)
and
y(3) = (1/3)*3 + 5 = 8
Then we have the point (3,8)
With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:
y = (1.15/0.65)*x + 8.90/0.65 = (115/65)*x + (890/65)
Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.
The points you can use are:
y(0) = (115/65)*0 + (890/65) = 13.7
the point is (0, 13.7)
and:
y(1) = (115/65)*1 + (890/65) = 15.5
The point is (1, 15.5)
Below you can see the graphs of both functions:
blue: y = -(1.15/0.65)*x + 8.90/0.65
red: y = (1/3)*x + 5
The answer is in the picture below!
A bag containing food has mass 3.813 kg. When the bag is empty its mass is 257 g. Find in kilograms the mass of the fruit
Answer:
I think it is 0.257 kg
Step-by-step explanation:
To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:
257÷1000= 0.257 Kg
The mass of the fruits in kilogram (kg) is 3.556 kg
Given:
Mass of the bag containing fruits = 3.813 kg
Mass of the empty bag = 257 g
convert
257 g to kg
257 g = 0.257 kg
Mass of the bc fruits = Mass of the bag containing fruits - Mass of the empty bag
= 3.813 kg - 0.257 kg
= 3.556 kg
Therefore, the mass of the fruits in kilogram is 3.556 kg

how would I solve the system x + 2y = 13, -x + y = 5 when using elimination
Answer:
x + 2y = 13}(add the both eqns)
-x + y = 5}
x +(-x) = 0
2y + y = 3y
13 + 5 = 18
then,
3y = 18
y = 6
from
x + 2y = 13
x = 13 - 2(6)

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.
Answer:
the answer is 0.204
Step-by-step explanation:
The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
How to determine the probability?The probability that a tire is defect is given as:
p = 5%
The required probability is then calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Where:
n = 5 --- number of tires
x = 1 ---number of tires with defect
So, we have:'
[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]
This gives
[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]
Evaluate the product
P(1) = 0.204
Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

Given the triangle below with centroid G, determine the following values.
If EG=3.5, then GB= and BE= If AD=15, then AG= and DG= If CG=6x, then FG- and CF=
Answer:
GB = 7
BE = 10.5
AG = 10
DG = 5
FG = 3·x
CF = 9·x
Step-by-step explanation:
The given parameters are;
The centroid of the ΔABC = G
Segments CF, BE, and AD are median lines
EG = 3.5 Given
∴ EG = 1/3 × BE by definition of the properties of median line
∴ BE = 3 × EG = 3 × 3.5 = 10.5
BE = 10.5
GB = 2/3 × BE = 2/3 × 10.5 = 7 by definition of the properties of median line BE
GB = 7
Similarly;
Given that AD = 15, AG = 2/3 × AD = 2/3 × 15 = 10 by definition of the properties of median line AD
AD = 10
DG = 1/3 × AD = 1/3 × 15 = 5 by definition of the properties of median line AD
DG = 5
Similarly;
Given CG = 6·x
FG = 1/3 × CF
CF = 3 × FG
CG = 2/3 × CF = 2/3 × 3 × FG
∴ CG = 2 × FG
FG = CG/2 = 6·x/
2 = 3·x
FG = 3·x
CF = 3 × FG = CF = 3 × 3 × x = 9·x
CF = 9·x

Mia records the distance traveled in x minutes in the table below, while Alexa uses a graph to record her distance traveled over the same time period. Alexa’s Graph A graph has time (minutes) on the x-axis and Distance traveled (miles) on the y-axis. A line goes through points (4, 3) and (8, 6). Mia’s Table A 2-column table with 4 rows. Column 1 is labeled Time (minutes) with entries 10, 18, 20, 26. Column 2 is labeled Distance Traveled (miles) with entries 5, 9, 10, 13. Based on the data on the graph and in the table, which statement gives an accurate comparison? Alexa traveled at a faster rate because the slope of her line is Three-fourths, which is greater than the slope of the line described by the data in Mia’s table. Alexa traveled at a faster rate because the slope of her line is Four-thirds, which is greater than the slope of the line described by the data in Mia’s table. Mia traveled at a faster rate because the slope of the line described by the data in her table is One-half, which is greater than the slope of the line on Alexa’s graph.

A pet shop sells goldfish for $ 9 per dozen. How much would 6 goldfish cost? How many goldfish could you buy with $50?
Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
