Answer:
y=-3/2x-2
Step-by-step explanation:
simplify 3x+2y=6 first
-3x. -3x
2y= -3x+6
Divide by 2
y= -3/2x+3
since it's parallel you would use the same slope
slope= -3/2x
Now you need to find b (x-intercept)
point (-2,1)=(x,y) use this to plug into y=mx+b
=
(1)=-3/2(-2)+b (simplify)
1 = 3+b
-3 -3
-2= b
so put it together and get
y=-3/2x-2
The growth of a tree in Andy's backyard has slowed down as the tree has continued to age. The heights of the tree over the past four years are: 10 feet, 11 feet, 12.1 feet, and 13.31 feet. Write a recursive formula for the height of the tree
Answer:
9.091(1.1^n)
Step-by-step explanation:
Given the height of a tree for the past 4 years given by the sequence;
10ft, 11ft, 12.1ft, 13.31ft...
We can see that the sequence is in geometric progression since they have a common ratio;
The nth term of a geometric progression is expressed as;
Tn = ar^n-1
a is the first term
r is the common ratio
Given
a = 10
r = 11/10 = 21.1/11 = 13.31/12.1 = 1.1
Substitute into the formula;
Tn = 10(1.1)^{n-1}
Tn = 10(1.1^n)/1.1
Tn = 9.091(1.1^n)
Hence the recursive formula for the height of the tree is expressed as 9.091(1.1^n) where n is the total number of tree.

Make & the subject of the
Formula
6x ta=5(x+t)
What is the answer please
Answer:
x = 5t - a
Step-by-step explanation:
The problem deals with making a variable the subject of the formula in the expression.
Given expression:
6x + a = 5(x + t)
We are to make x the subject of the formula in the expression
Solution:
6x + a = 5(x+t)
On the right hand side, expand the parentheses and distribute the term outside;
6x + a = 5x + 5t
Bring the term desired to be the subject to one side by adding (-5x) to both sides;
6x + (-5x) + a = 5x + (-5x) + 5t
x + a = 5t
Now add (-a) to both sides
x + a + (-a) = 5t + (-a)
x = 5t - a
A grocery store is selling peaches for $0.98 per pound. Is this a function or Not function
Answer:
This is a function. Use y=mx+b equation
Step-by-step explanation:
To find the x and y values, simply plug in 0.98 to m. For every pound of peaches, you pay $0.98. The equation would be y=0.98x, where x is the number of pounds of peaches and y is the total cost.

Answer:
The factor is 4.
Step-by-step explanation:
You can divide both 24 and 20 by 4, leaving you with 6x-5.
Highest common factor should be 4.
Given that,
The equation is 24x - 20.Based on the above information, the calculation is as follows:
Here 24 and 20 should be divisible by 4
So,
= 4(6x - 5)

The table and the graph show the relationship between the edge length, x, of a cube and its surface area, y. Is the relation a function?
Also weirdgamergirl7 if your watching this, ty for the answers <3
Answer:
Yes, the relationship between x and y is a non-linear function.
Step-by-step explanation:
Given the table
Edge Length, x Surface Area, y
1 6
2 24
3 54
4 96
The table values clearly represent a function, because each input value has one and only one output value. i.e. there is no repetition of x values.Also from the table values and the graph, it is clear that the function is not a linear function, because the graph is not a straight line. Also, In a cubic function, the highest power over the x variable(s) is 3. So, it is not a linear function.Hence, we conclude that Yes, the relationship between x and y is a non-linear function.
Therefore, the 'last option' is correct.
Answer:
no it is non- linear

The diameter of a circle is 16 meters. What is the angle measure of an arc 6 meters long?
Answer:
42.99° or approx 43°

Diameter of circle d = 16 m
Lenght of arc l= 6 m
Let the angle measure of the arc be [tex] \theta [/tex]
By length of arc formula of a circle.
[tex]l = \frac{ \theta}{360 \degree} \times\pi d \\ \\ 6 = \frac{ \theta}{360 \degree} \times 3.14 \times \: 16 \\ \\ \theta = \frac{6 \times 360 \degree}{3.14 \times 16} \\ \\ \theta = \frac{2160\degree}{50.24} \\ \\ \theta = 42.9936306 \degree \\ \\ \theta = 42.99 \degree \approx \: 43 \degree[/tex]

Question:
Identify the function that reflects f(x) = 14x3 − 7x2 + 6 across the y-axis and shifts it 6 units up.
Answer:
h(x) = 14x3 + 7x2 + 12
h(x) = −14x3 − 7x2 + 12
h(x) = −14x3 − 7x2
h(x) = 14x3 − 7x2
Answer: there's no answer, the correct answer is f(x) = -14x3 + 7x2
Step-by-step explanation:
1. f(x) = 14x3 − 7x2 + 6
2. reflection over y-axis : f(x) = -14x3 + 7x2 - 6
3. shift 6 units up : f(x) = -14x3 + 7x2 - 6 + 6
4. f(x) = -14x3 + 7x2
The correct function after reflection across the y-axis and shifts it 6 units up is,
⇒ h (x) = - 14x³ - 7x² + 12
What is Function?A relation between a set of inputs having one output each is called a function.
We have to given that;
The function is,
⇒ f (x) = 14x³ - 7x² + 6
Now, After reflection across the y-axis we get;
⇒ f (x) = f (- x)
⇒ f (-x) = 14 (-x)³ - 7 (-x)² + 6
⇒ f (-x) = - 14x³ - 7x² + 6
And, After shifts it 6 units up, we get;
⇒ f (x) = f (x) + 6
Hence, We get the value of function is,
⇒ h (x) = - 14x³ - 7x² + 6 + 6
⇒ h (x) = - 14x³ - 7x² + 12
