Write an equation for the line in slope- intercept form
points are:
-2,-2
-1,1
0,4
Answer:
y=3x+4
Step-by-step explanation:
Slope-intercept form is written as y=mx+b
m = the slope
slope is rise over run or (y2-y1)/(x2-x1). We need to choose which y value is y2 and the corresponding x value is the x2. If -2 is y2, then:
x2 = -2
y1 = 1
x1 = -1
then plug in the values.
(-2-1)/(-2-(-1))
-3/-1 = 3
m =3
then plug in values for the first equation. you can use any point on the line.
y = 3x+b
4 = 3*0 +b
4=0+b
b = 4
then write it with out x or y
y = 3x+4

2 The perimeter of a square is given as 12x + 20. Write two different expressions to
represent its perimeter. Use factoring for one way.
Answer:
The two expressions are;
4(3x + 5)
and
(6x + 10) + (6x + 10)
Step-by-step explanation:
Here, we want to write two different expressions to represent the perimeter of the square
The perimeter is given as 12x + 20
Using factoring, we can have this as;
4(3x + 5)
Otherwise, we can have
(6x + 10) + (6x + 10)

The triangles in the picture are congruent by which method.
Explanation:
Check out the diagram below. I've marked the angles that pair up which are congruent to one another. Note the order is important. The AAS rule is different from ASA. In the diagram, the green segments are not between the red and blue angles.
Note: the blue angles are congruent by the vertical angle theorem.
Let p=x^2+6p=x 2 +6p, equals, x, start superscript, 2, end superscript, plus, 6. Which equation is equivalent to (x^2+6)^2-21=4x^2+24(x 2 +6) 2 ?21=4x 2 +24left parenthesis, x, start superscript, 2, end superscript, plus, 6, right parenthesis, start superscript, 2, end superscript, minus, 21, equals, 4, x, start superscript, 2, end superscript, plus, 24 in terms of p ?
Answer:
Step-by-step explanation:
Given p = x²+6
We are to express (x²+6)-21 = 4x²+24 in terms of p
We need to rewrite the expression first
(x²+6)²-21 = 4x²+24
Factor out 4 from the right hand side;
(x²+6)²-21 = 4(x²+6)
Replace x²+6 with p
p²+21 = 4p
Collect like terms
p²-4p = -21
p²-4p+21= 0
Hence the required equation is p²-4p+21= 0
Answer: p^2-4p-21=0

Each box holds 6 black markers and 4 red markers. Derek has 0 boxes of markers. Write a number sentence that shows how many markers Derek has. Explain how you found your answer.
Answer:
0 x 1 x 10 = 0
Step-by-step explanation:
0 x 1 x 10 = 0
This is problem that has to do with multiplication with 0.
Since Derek has 0 boxes of markers and each box contains 10 markers, 6 black and 4 red, think of it as Derek having 0 groups of a box of markers. This means Derek has 0 boxes where each box contains 10markers.
0 boxes means Derek has no markers.

938 feet
942 feet
1,142 feet
5,628 feet
Answer:
Step-by-step explanation:
If Kale is at 2345 feet and needs to reach 3283, he will need to travel another 938 feet.
The vertical distance between Kale and the mountain peak is ft
How to determine the vertical distance?The given parameters are:
Hike Distance = 2345 ft
Peak = 3283 ft
Let the vertical distance be x.
So, we have:
x + 2345 = 3283
Subtract 2345 from both sides
x = 938
Hence, the vertical distance between Kale and the mountain peak is ft

1.A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the perimeter of the triangle if the second side is length s?
(2s + 65) + (s) + (s + 10) = 165
(2s - 65) + (s - 10) = 165
(2s - 65) + (s) + (s - 10) = 165
3s = 165
2. A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What is the length of each side of the triangle?
65 cm, 55 cm, 45 cm
55 cm, 60 cm, 50 cm
45 cm, 60 cm, 60 cm
not enough information to solve
FIRST, we need variables. Once we define variables, it's much easier to turn this word problem into a math problem.
Let a = first side
Let b = second side
Let c = third side
NOW, we can turn the words into equations:
"a triangle has a perimeter of 165 cm."
a + b + c = 165
"the first side is 65cm less than twice the second side."
a = 2b - 65
"the third side is 10cm less than the second side."
c = b - 10
Before we finish, I have to ask: Who writes problems like this??? Pointless problems like these are why kids don't like math! Ugh. Drives me crazy. It's a shame, because solving math problems really does have a certain satisfaction, once you learn how. [Okay. I'm done. Back to the problem.]
If we could get this to have only one variable, we could solve it. Substitution to the rescue!
a + b + c = 165 (rewrote equation from above)
(2b - 65) + b + (b - 10) = 165 (substituted "a" and "c" from equations above)
See how that works? Let's solve it.
2b - 65 + b + b - 10 = 165 (dropped the parentheses, because there was nothing to distribute, not even a minus sign)
4b - 75 = 165 (combined like terms)
4b = 240 (added 75 to both sides)
b = 60 (divided both sides by 4)
We found the second side! We can find the first and third sides using those equations from above:
a = 2b - 65
a = 2*60 - 65
a = 120 - 65
a = 55
c = b - 10
c = 60 - 10
c = 50
All done.

Step One - Define the Unknown Variable
First we need to define our unknown variable. For this case, I am going to use the letter 's' for the second side of the triangle (no actually because the question told you to). The reason I am using the second side as the unknown is because the second side is independent. The first and third sides' lengths depend on the length of the second side.
Step Two - Write an Equation
We need to use what we know to write the equation. First, we know that the perimeter of a polygon is the sum of the lengths of all the sides. The first side is 65 less than two times 's'. This would be 2s-65. The second side is just s. The third side is 10 less than 's'. So it would be s-10. The perimeter is all of the sides added up, so the expression for all the sides added up is (2s-65)+(s)+(s-10). The first, second, and third side added up is 165. So the equation for 1. is (2s-65)+(s)+(s-10) = 165.
Step Three - Solve the Equation
To solve the equation, you need to isolate the variable, which is 's'.
First, let's simplify the equation.
(2s-65)+(s)+(s-10) = 165.
4s-75 = 165.
Now we need to remove the 75. To get rid of the 75, you must add 75. But since you are adding 75 to one side of the equation, you must add 75 to the other side of the equation to make it equal.
4s-75+75 = 165+75
4s = 240
Now we need to remove the 4. To get rid of the 4, you have to divide each side by 4.
4s÷4 = 240÷4
s = 60
The length of the second side is 60 cm.
Step Four - Find the Lengths of all Sides
Now we know the length of the second side, we can find the length of the other sides.
The first side is 65 less than two times of 60.
Two times of 60 is 60×2 or 120.
65 less than 120 is 120-65 or 55.
The first side is 55 cm.
The third side is 10 less than 60.
10 less than 60 is 60-10 or 50.
The third side is 50.
So the lengths of the three sides are 55, 60, and 50.
Step Five - Check Your Answer
Now let's see if the three sides added up equals to 165.
Well, 55+60+50 does equal 165, so we know this is right.
The equation that represents the perimeter of the triangle is (2s + 65) + (s) + (s + 10) = 165. The length of each side of the triangle is 55, 60, and 50.

Answer:
C
Step-by-step explanation:
First, since y is less than or equal to x+4, that shows that it must be either C or D, because both of those regions are below the line x+4.
Next, since y is more than or equal to -3/2x-1, this shows that C is the answer.
We can also check by seeing the graph when x = 0. Notice that y = 0 is in the region C, and notice that 0 satisfies the 2 inequalities, because -1≤0≤4.
