Answer:
this is what I would say from my own opinion
Step-by-step explanation:
Tree planting is very important because trees give us oxygen and helps us live and helps keep the economy alive. The way trees are planted are very important because you have to care for it a lot. if it isn't done correctly then the tree will die. Trees need lots of water, sunshine. if the tree isn't correctly planted then it will just be a fail of getting a tree. millions of trees keeps us living and gives us lots of oxygen.
i will only say 3 ways
1.give it water
2.let it touch with sunlight
3.let it grow in soil

Graph two more functions in the same family for which the parameter being changed is the slope m and is greater than 1.
Step-by-step explanation:
negative 1 because thats were the line crosses the x axis and 4 because its close to the slope
PLEASE I NEED HELP INSTANTLY
I WILL GIVE BRAINLY AND THANKS
Answer:
so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7

The sum of two numbers is twice their difference. The larger number is 5 more than twice the smaller. Find the numbers.
Answer:
18 and 6
Step-by-step explanation:
The sum of two numbers is twice their difference: 18 + 6 = 24, 18 - 6 = 12. 24 is twice of 12.
The larger number is 5 more than twice the smaller. Twice of 6 is 12. 5 more than 12 is 18.

Use matrices to write the equation of the function in the form y = mx + b that contains the points
(6.-29) and (-4,31). Record your values for slope, m, and y-intercept, b, below. Note: Your
answers should be integers.
The line has a slope of -6 and a y intercept of 7.
The linear equation is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y, x are variables.
The equation of the line passing through the points (6.-29) and (-4,31) is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-29)=\frac{31-(-29)}{-4-6}(x-6)\\\\y+29=-6(x-6)\\\\y=-6x+7[/tex]

Answer:
it’s m= -1/4
Step-by-step explanation:
it’s the slope
The slope of the line is 4.
\What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.2The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
A line is perpendicular to the line y = 4x - 3.
y = 4x - 3 is in the form of y = mx + c
So,
m = 4.
Now,
The line has a y-intercept at (0,-2).
So,
c = -2
Now,
The equation of a line is given by:
y = mx + c
y = 4x - 2
Thus,
Slope is 4.

[There's a lot to read here. If you read it, maybe you'll have a better understanding.]
This is asking you the first step required to solve each of the equations.
The general process of solving an equation involves performing operations that result in the variable of interest being on one side of the equal sign (by itself), and everything else being on the other side. When variable and constant terms are mixed, we generally want to remove the variable term.
The underlying rule for all of this is "whatever is done to one side of the equation must also be done to the other side." The exceptions are simplification and substitution.
"Inverse" operations are of use in this process. That is why you are taught about the "additive inverse" (negative) of a number, and the "multiplicative inverse" (reciprocal) of a number. Adding the additive inverse results in the additive identity element (0). Similarly, multiplying by the multiplicative inverse results in the multiplicative identity element (1). Adding 0 or multiplying by 1 leaves only the original value.
__
With this in mind, we can look at the given equations to see what is needed to solve them.
2 +2y = y
We see that the left side of the equation has both a constant term and a variable term. To remove the variable term we add its additive inverse: (-2y). Adding a negative value is the same as subtracting a positive value. That is, we can describe what we want to do as "subtract 2y from both sides".
When we do that, the result is ...
2 +2y -2y = y -2y . . . . . here, we show the subtraction
2 = -y . . . . . . . . . . . . . and this is the result of simplifying that.
Notice the y term is now on one side of the equal sign and the constant is on the other side. We are one step closer to the solution, which is the whole point.
__
5(y -4) = 2y
This equation has parentheses. It often works well as a first step to eliminate the parentheses, generally using the distributive property. That is, we "distribute 5".
When we do that, the result is ...
5(y) -5(4) = 2y . . . . . . . . here, we show the distribution
5y -20 = 2y . . . . . . . and this is the result of simplifying that
This puts us one step closer to the solution, which is the whole point.
__
5y = 10 -2y
Here, the unwanted variable term is -2y on the right side of the equation. To remove it, we add 2y to both sides.
When we do that, the result is ...
5y +2y = 10 -2y +2y . . . . . . . showing the addition of 2y
7y = 10 . . . . . . . . . . . . . . . simplified
This puts us one step closer to the solution.
__
5 = 25y
This equation has the variable term and the constant term already separated. However, there is a coefficient on the variable term that is not equal to 1. We want to make that coefficient be 1. To do that, we multiply it by its multiplicative inverse: 1/25. That is, we divide both sides by 25.
When we do that, the result is ...
5/25 = 25y/25 . . . . . . showing division by 25
1/5 = y . . . . . . . . . simplified (and the fraction reduced)
This gives us the solution. There are no more steps required.
