Answer:
x + y and x - y are the simplest system of linear equations that has the ordered pair.
Example:
x + y = -2
x - y = 8
That's the answer to the ordered pair (3,-5)
Remember x = 3 and y = -5

-Graphing Linear equalities with slope and y-intercept-
You recognize the slope from [tex]\frac{rise}{run}[/tex] when moving from point to point. You will notice that the points are not all an even distance from each other so in this case you will use to slope formula to find the answer.
Slope formula: [tex]\frac{y2 - y1}{x2 -x1}[/tex]
= [tex]\frac{2 - 1}{2 - 0}[/tex]
= [tex]\frac{1}{2}[/tex]
The slope is 1/2
How do I graph y = -1 = 2x and y = -4 + 2x?
Answer:
Slope = Rise/Run
To graph, you first need the y-intercept.
In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.
In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.
To find y-intercept:
y = mx + b | main things: m = slope b = y-intercept

What is the answer for this question
Answer:
B. 335.5 in.²
Step-by-step explanation:
The pencil decoration can be broken down into a rectangle and a triangle.
The area of the pencil decoration is the sum of the areas of the rectangle and triangle.
The rectangle has length b and width a.
The triangle has base a and height a.
total area = area of rectangle + area of triangle
total area = length × width + base × height / 2
total area = b × a + a × a / 2
From the given information, we see that a = 11 in., and b = 25 in.
total area = b × a + a × a / 2
total area = (25 in.) × (11 in.) + (11 in.) × (11 in.) / 2
total area = 275 in.² + 60.5 in.²
total area = 335.5 in.²

PLEASE HELP YOU WILL GET 100 PIONTS!
Answer:
x = 55°
Step-by-step explanation:
The angles are complementary. That means that they add to 90.
x + x - 20 = 90 Combine like terms
2x - 20 = 90 Add 20 to both sides
2x - 20 + 20 = 90 + 20
2x = 110 Divide both sides by 2
x = 55
Helping in the name of Jesus.
Answer:
x = 55 degrees; the angles are complementary
Step-by-step explanation:
First of all, the angles are complementary. I say this because complementary angles add up to 90 degrees and the square symbol identifies the angle as being a 90-degree angle.
Next, you add [tex]x-20+x[/tex] and set it equal to 90. With some quick addition and some properties of equality, you get the answer of 55 degrees.
Mary has 400 slices of pizza. She gives 30 to Cambri,96 to Maria,99 to Falli,43 to Sam and 32 to Callin. How many slices does she have left?
Answer:
The answer to your problem is, 100 slices.
Step-by-step explanation:
First lets add up all the numbers that she gives away
30+96+99+43+32 =
300.
If she gave out 300 slices of pizza then here left over is:
400 - 300 = 100.
Thus the answer to our problem is, 100 slices.

The 12 students in the Environmental Club represent 25% of the students in the seventh grade. How many students are in the seventh grade? I would appreciate your help!
Answer:
48
Step-by-step explanation:
25% × x = 12
0.25x = 12
then you would divide.
x = 12 / 0.25
x=48
so 48 students

Which expression is equivalet to (3x-1)-2.75(x+2)
A. 0.25x - 6.50
B. 0.25 + 1.00
C.0.25 + 4.50
D.0.25 -3.00
I would love an explanation to help me understand how to solve the other problems like this one
it is A. 0.25x - 6.50
You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50
Then you combine like terms so 3x - 2.75 will equal 0.25x
The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50
And finally, the expression will be 0.25x - 6.50
