Step-by-step explanation:
Solve the system of equations by the addition method.
8x+y=-2
4x-y=-14
[tex]8x + y = -2[/tex]
[tex]4x - y = -14[/tex]
To solve this via the addition method, we just need the two equations together; that means that we will create a new equation where the terms on the left side of both equations are added together and are set equal to the sum of the terms on the right side of both equations:
[tex](8x + y) + (4x - y) = (-2) + (-14)[/tex]
[tex]8x + y + 4x - y = -2 - 14[/tex]
[tex](8x + 4x) + (y - y) = -16[/tex]
[tex]12x + 0 = -16[/tex]
[tex]x = \frac{-16}{12}[/tex]
[tex]x = \frac{-4}{3}[/tex]
Now that we have solved for one term, we can plug this value into either equation to get the value for the other:
[tex]4x - y = -14[/tex]
[tex]4(\frac{-4}{3}) - y = -14[/tex]
[tex]\frac{-16}{3} - y = -14[/tex]
[tex]\frac{-16}{3} + 14 = y[/tex]
[tex]\frac{26}{3} = y[/tex]
This means the solution to the system of equations is [tex](-\frac{4}{3}, \frac{26}{3})[/tex]
Answer:
Step-by-step explanation:
8x + y = -2
4x - y = 14
12x = 12
x = 1
8 + y = -2
y = -10

Step-by-step explanation:
The scale on a map of Virginia shows that 1 inch represents 45 miles. the actual distance from Richmond, Va, to Washington, D.C., is 110 miles. on the map, how many inches are between the two cities?
Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches
I need help ASAP plzzzz help
Answer:
D. X = 130 in.
Step-by-step explanation:
a² +b² =c² (Pythagorean theorem)
50² + 120²=c²
2,500 + 14,400 =c²
16,900 = c²
√16900 = √c²
130 = c
X = 130 in.
The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5. The perimeter of ΔDEF is 48 inches. What is the perimeter of ΔABC?
Answer:
28.8 inches
Step-by-step explanation:
We solve the above question using Proportion
The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5.
ΔABC/ΔDEF = 3/5
Hence,
The perimeter of ΔDEF is 48 inches.
Let the perimeter of ΔABC = x inches
3/5 = x/48
Cross Multiply
5x = 48 × 3
x = 48 × 3/5
x = 28.8 inches
The perimeter of ΔABC is 28.8 inches
Drag each sequence to show whether it is a linear function, an exponential function, or
not a function.
I will give you 20 brainiest points!! Please help.
Answer:
Step-by-step explanation:
From the picture attached,
Option A
From the given table,
Ratio of the 2nd value and 1st value = [tex]\frac{8}{4}=2[/tex]
Ratio of 3rd value and 2nd value = [tex]\frac{16}{8}=2[/tex]
There is a common ratio of 2.
Therefore, the given table will represent an exponential function.
Option B
Given recursive formula of the sequence is,
[tex]A_1=3[/tex]
[tex]A_n=5.A_{n-1}[/tex]
From this recursive formula sequence will be,
3, 15, 75, 375,.......
Therefore, it's an exponential function.
Option C
[tex]F_n=3n+17[/tex]
Given function is in the form of a linear function (y = mx + b),
Therefore, it's a linear function.
Option D
From the given table,
Difference between 2nd value to the 1st value = 8 - 4 = 4
Difference between 3rd value to the 2nd value = 12 - 8 = 4
Therefore, there is a common difference of 4 in each successive term to the previous term.
Hence, the given table represents a linear function.

Step-by-step explanation:
sin 38° = EF/18
EF = 18·sin 38°
EF = 11.1
to find DF:
sin 90°/18 = sin 52°/DF
1/18 = .79/DF
DF = 14.2

The perimeter of a rectangle is 76cm.
Its longest side has a length of 29cm.
State the length of the shortest side.
Answer:
The length would be 9cm
Step-by-step explanation:
Because the perimeter is 76, you have to add 29 to 29 which equals 58, then you have to subtract 58 from 76, which is 18. The last episode is divide 18 by 2 because re are two sides remaining. So answer would be 9. To check the answer you can add 29+29+9+9

There is one dot at 3.45. What does that value
represent?
A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.
There is a 1 out of 100 chance that the population
mean GPA is = 3.45.
O A majority of the sample of 100 students had a GPA
of r = 3.45.
