Answer:
8.5
Step-by-step explanation:
15x+10+6x+2=180 (add up to we 180 because they are alternate eachother
21x+12=180 combine like terms
21x=178 subtract 12 from both sides
x~~8.5 divide both sides by 21

What is the value of x in this figure?
Answer:
x = 65 degrees
Step-by-step explanation:
Sum of all three sides in a triangle is 180
48 + 67 + n = 180
180 - (48 + 67) = 65
The missing angle and angle X are vertical angles, so they are the same angle.
angle X = 65 degrees

Answer:
x = 5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3x - 6 = 9
Step 2: Solve for x
Add 6 to both sides: 3x = 15Divide 3 on both sides: x = 5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(5) - 6 = 9Multiply: 15 - 6 = 9Subtract: 9 = 9Here we see that 9 does indeed equal 9.
∴ x = 5 is the solution to the equation.

Hey do you have the answer?
Find the equation of the linear function represented by the table below in slope- intercept form. х: -2, 2, 6, 10 y: -5, 7, 19, 31
Answer:
y = 3x + 1
Step-by-step explanation:
Slope-intercept form is y = mx + b.
To find the slope (m), you use the equation (y1-y2)/(x1-x2). Plug in your points (-2, -5) and (2, 7) to get (-5 - 7)/(-2 - 2). Simplify the formula to get a slope of 3. This is your variable m.
To get the entire equation, finding b in the process, you use the formula y - y1 = m(x - x1). Replace m with 3. Using the point (-2, -5), replace it with (x1, y1) respectively to get y + 5 = 3(x + 2). Distribute to get y + 5 = 3x + 6. Isolate the y to get your final answer: y = 3x + 1.

the first part:
graph the points and then find the slope
m=-7/5
the second part:
slope= m in y=mx+b
m=-7/5
the last part:
they are parallel because they have the same slope

What is the value of this function evaluated at f(-3): f(x) = 2x2+ 5x - 9? F -6 G -42 H 42 J 12
Answer:
f(-3) = -6
Step-by-step explanation:
f(x) = 2x^2+ 5x - 9
We are to find f(-3)
f(-3) = 2(-3)^2+ 5(-3) - 9
f(-3) = 2(9)-15 - 9
f(-3) = 18 -15 -9
f(-3) = 18-24
f(-3) = -6

10.) Dilation with the center at the origin and a scale factor of 1/3.
Step-by-step explanation:

3.) d
b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)
Hope this helps ya!!!

Step-by-step explanation:
Cnidarians are another major group of invertebrates. Jellyfish, coral, hydra and anemone are examples of cnidarians. They have soft bodies and no heads. They have stinging tentacles that they use for defense and to capture prey. Cnidarians have radial symmetry. That means that their parts are arranged around a center. If you were to draw a line to cut them in half in any direction, the two sides will always match. Radial symmetry is often a characteristic of more simple animals than bilateral symmetry, where there is only one line you could draw to make two sides match. With bilateral symmetry, different body parts may have different functions. With radial symmetry, the entire body may perform all life functions.
Jellyfish do not have (what?)
a. heads.
b. tentacles.
c. symmetry.
d. soft bodies.
