y=3x+14
2x-3y=-14
Substitution method
Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.

20. What is the order of rotational symmetry for each design (i.e. what is the angle of rotation to create
the rotational symmetry)?
Your answer should be:
The order of rotational symmetry of a regular polygon is the same as the number of sides of the polygon. You can also deduce the order of rotational symmetry by knowing the smallest angle you can rotate the shape through to look the same. 180° = order 2, 120° = order 3, 90° = order 4.
I hope this helped :)

If the spinner is spun 50 more times, how many of
these times would you expect the pointer to land on
blue?
Find the area of the figure.
Answer:
29 sq in
Step-by-step explanation:
Area of the figure = Area of square + Area of parallelogram + Area of rectangle
[tex] = {2}^{2} + 5 \times 3 + 2 \times 5 \\ \\ = 4 + 15 + 10 \\ \\ = 29 \: {in}^{2} [/tex]
Answer:
29 in
Step-by-step explanation:
the rectangle at the bottom would be 10 when multiplying its base and its height which are 5 and 2.
the parallelogram in the middle would be 15 from multiplying 5 * 3.
and the square at the top would be 4 from multiplying 2 * 2.
so now you add that up and you should get the total i got.
Joe wants to paint a diagonal line across a sign over the door of his office. The sign measures 8 ft. by 6 ft. How long will the diagonal line be?
Answer:
10 ft.
Step-by-step explanation:
By using the pytahgorean theorem a² + b² = c² we can determine the answer of 10 ft. If you do not know already the length and width are the a and the b so a=6 and b=8. by squaring both of these we get a=36 and b=64 (squaring is just the number times itself so 3² would be 3x3) by adding both of these squared values we get 64+36=100 which means that c²=100 so to get our final answer we just take the square root of c² which is the opposite of squaring it. So √100=10 and that is our final answer

The Domain means all possible values that x can be.
The range is the outcomes you get when you plug in the domain.
For each function, choose values for x.
Then solve
The outcome you get is f(x)
F(X) is an easier way of saying y,
If its easier this way, in terms of y, the equations would be y=-4x, y=x+6, and y=3x+2. You would solve these as you solve linear equations!
Ordered pair of [x,f(x)]
Lets Start!
#1
x | -4x | f(x)
Lets use the values -2, -1, 0, 1, and 2 for x.
-2 | -4(-2) | 8 (-2,8)
-1 | -4(-1) | 4 (-1,4)
0 | -4(0) | 0 (0,0)
1 | -4(1) | -4 (1,-4)
2 | -4(2) | -8 (2,-8)
Domain we have right now- {-2,-1,0,1,2}
Range we have right now- {8,4,0,-4,-8}
Domain and Range of entire function- All real numbers
#2
x | x+6 | f(x)
Lets use the values -2, -1, 0, 1, and 2 for x.
-2 | -2 + 6 | 4
-1 | -1 + 6 | 5
0 | 0 + 6 | 6
1 | 1 + 6 | 7
2 | 2 + 6 | 8
Domain we have right now- {-2,-1,0,1,2}
Range we have right now- {4,5,6,7,8}
Domain and Range of entire function- All real numbers
#3
x | 3x + 2 | f(x)
-2 | 3(-2) + 2 | 4
-1 | 3(-1) + 2 | -1
0 | 3(0) + 2 | 2
1 | 3(1) + 2 | 5
2 | 3(2) + 2 | 8
Domain we have right now- {-2,-1,0,1,2}
Range we have right now- {4,-1,2,5,8}
