Determine if (3, 7) is a Solution or not Solution to the linear system.
y = 2x + 1
y = -4x + 7
Answers
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.

Answers
Answer: see below
Step-by-step explanation:
Slope-Intercept form is: y = mx + b where
m is the slopeb is the y-intercept1) 2x + y = 2
y = -2x + 2 Subtracted 2x from both sides
↓ ↓
m= -2 b= 2
Slope (m) = -2 y-intercept (b) = 2 Equation: y = -2x + 2
2) 4x + y = -5
y = -4x - 5 Subtracted 4x from both sides
↓ ↓
m= -4 b= -5
Slope (m) = -4 y-intercept (b) = -5 Equation: y = -4x - 5
3) 4x + 2y = 6
2y = -4x + 6 Subtracted 4x from both sides
y = -2x + 3 Divided 2 from both sides
↓ ↓
m= -2 b= 3
Slope (m) = -2 y-intercept (b) = 3 Equation: y = -2x + 3
4) -6x + 3y = -9
3y = 6x - 9 Added 6x to both sides
y = 2x - 3 Divided 3 from both sides
↓ ↓
m= 2 b= -3
Slope (m) = 2 y-intercept (b) = -3 Equation: y = 2x - 3
5) x + 3y = 6
3y = -x + 6 Subtracted x from both sides
y = (-1/3)x + 2 Divided 3 from both sides
↓ ↓
m= -1/3 b= 2
Slope (m) = -1/3 y-intercept (b) = 2 Equation: y = (-1/3)x + 2

Step-by-step explanation:
To set up scientific notation you need to move the decimal point so there is a one digit other than zero in the first part (9.23). To do this you move the decimal point to the right 5 digits, accounting for the negative 5 (10^-5).
It's negative cause it's going right, if it was moving left it would be positive.

Equation of the nth term of the given arithmetic sequence is equals to
aₙ = 3n +9.
What is arithmetic sequence?
" Arithmetic sequence is a sequence in which difference between two consecutive terms remain constant. "
Formula used
nth term in Arithmetic sequence
aₙ = a₁ + (n -1)d
Where
aₙ=nth term of the sequence
a₁ = first term of the sequence
n = number of terms
d = common difference
According to the question,
Given arithmetic sequence is
12, 15, 18, 21, ......
a₁ = 12
d = 15 - 12
= 3
Substitute the values in the formula of nth term we have,
aₙ = 12 + (n - 1) 3
⇒ aₙ= 12 + 3n -3
⇒ aₙ= 3n +9
Hence, equation of the nth term of the given arithmetic sequence is equals to aₙ = 3n +9.

How many months will it take for Carolines hair to be atleast as long as Trinitys hair? Define the variable.
Answers
Answer:
30 months
Step-by-step explanation:
Let the number of months = x
Carolines hair is 7 inches long and grows up to 1/5 inch each month.
7 + (1/5)x
= 7 + 0.2x
Trinity's hair is 10 inches long and grows about 1/10 inch each month.
10 + (1/10)x
10 + 0.1x
How many months will it take for Carolines hair to be atleast as long as Trinitys hair?
Caroline = Trinity
7 + 0.2x = 10 + 0.1x
0.2x - 0.1x = 10 - 7
0.1x = 3
x = 3/0.1
x = 30 months
Therefore, it will take for 30 months for Caroline's hair to be atleast as long as Trinitys hair

(-1,-3)
Answers
The point which will be in function is f-'(x) is (1, -3).
We are given that;
The point (-3,1) is in the function f(x)
Now,
Function is a type of relation, or rule, that maps one input to specific single output.
A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
To find the inverse of a function, we need to switch the inputs and outputs of the function.
In other words, if f(x) = y, then f^ {-1} (y) = x.
This means that if (-3, 1) is in the function f(x), then (1, -3) will be in the function f^ {-1} (x).
Therefore, by function answer will be (1, -3).
