As the area is 12, the length multiplied by the width must equal 12
Therefore, we can eliminate option B and option D as they wouldn't multiply to give 12
Let's test option A to see if it gives a perimeter of 16
2 + 6 + 2 + 6 = 16
As you see, this sums to 16
Thus, your answer is option A

Solve system of equations for x + y: 3x + 2y = -18 & 2x + 9y =-12
Answer:
(- 6, 0 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = - 18 → (1)
2x + 9y = - 12 → (2)
Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is
6x + 4y = - 36 → (3)
- 6x - 27y = 36 → (4)
Add (3) and (4) term by term to eliminate x
- 23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and evaluate for x
Substituting into (1)
3x + 0 = - 18
3x = - 18 ( divide both sides by 3 )
x = - 6
Solution is (- 6, 0 )

Solve for x 3x +2= y; y=5. X=____
Answer:
X=1
Step-by-step explanation:
Solve this like any other two step equation.
But first plug in y value.
3x + 2 = 5
Subtract 2 from each side
3x = 3
Now divide each side by 3
X=1
Hope this helps plz mark brainliest!
Answer:
[tex]3x +2= y; y=5. \\3x +2 = 5\\3x =5 -2\\3x = 3\\Divide-both-sides-of-the-equation-by 3\\\frac{3x}{3} =\frac{3}{3} \\x = 1[/tex]
Step-by-step explanation:
x = 1
Step 1 : Substitute 5 for y in 3x +2= y
Step 2 : Collect like terms
Step 3 : Simplify
Divide both sides of the equation by 3
x = 1

Answer:
x ≥ 4
Step-by-step explanation:
There is a closed circle at 4 so it means equals
The line goes to the right so that means greater
x ≥ 4
Answer:
D or x≥4
Step-by-step explanation:
The number has to be 4, since the dot lies on it, so that excludes A and B.
It is greater, because the arrow is pointing right instead of left.
Since the circle is closed, then it means that it includes 4.
So, C would not be the answer, because it is read as " x is greater than 4"
it should be D, which is " x is greater than or equal to 4" (since the circle is closed).
Thus, D is the answer

Translate ƒ(x) = |x| so that it's translated down by 2 units and to the left 6 units. What's the new function g(x)?
A) g(x) = |x – 6| + 2
B) g(x) = |x – 6| – 2
C) g(x) = |x + 6| + 2
D) g(x) = |x + 6| – 2
Answer:
D) g(x) = |x +6| -2
Step-by-step explanation:
To translate f(x) h units to the right and k units up, you use the transformation ...
g(x) = f(x -h) +k
You want to translate your function 6 units left and 2 units down, so (h, k) = (-6, -2) and the transformed function is ...
g(x) = |x +6| -2

lions = 6
crocs = lions -2 = 6-2 =4
monkeys = 5*crocs = 5*4 = 20
the rest are elephants
35 - 20 -4-6 = 5
5 elephants
Answer:
5
Step-by-step explanation:
6-2=4
4*5=20

A parabola can be represented by the equation x2 = 2y. What are the coordinates of the focus and the equation of the directrix? focus: (0,8); directrix: y = –8 focus: (0, one-half); directrix: y = negative one-half focus: (8,0); directrix: x = –8 focus: (one-half, 0); directrix: x = negative one-half
Answer:
b)
i) Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]
ii) The equation of the directrix is
[tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]
Step-by-step explanation:
Step(i):-
A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not in a line) in the plane
• The Fixed line is called the directrix of the parabola.
• The Fixed point is called the focus of the parabola.
• A line through the focus and perpendicular to the directrix is called the axis of the parabola.
• The point of intersection of parabola with the axis is called the vertex of the parabola.
Given Parabola x² = 2 y
Comparing x² = 4 a y
4 a = 2
[tex]a = \frac{1}{2}[/tex]
Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]
Step(ii)
The equation of the directrix is y = -a or y +a=0
The equation of the directrix is
[tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]
The equation of the directrix is 2 y +1 =0

A leaf hangs from a branch 12 feet in the air. It falls to the ground at a rate of 0.25 feet per second. Which graph could represent the leaf’s height in feet as a function of time, in seconds, after leaving the branch? A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (4, 20 ), (6, 14), and (12, 0). A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 8), and (20, 2). A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 16), (6, 8), and (12, 0). A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).
Answer:
A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).
Step-by-step explanation:
The y-intercept of the graph is the height of the leaf at the beginning, that is, 12 ft. This means that point (0, 12) is on the line.
The leaf falls to the ground at a rate of 0.25 feet per second, this means that after 8 seconds, the leaf travel 8*0.25 = 2 ft. Given that it started at 12 ft, its height is 12 - 2 = 10 ft. In other words, the point (8, 10) is on the line. Similarly, its height after 16 seconds is 12 - 16*0.25 = 8 ft, that is, the point (16, 8) is on the line.
Answer:
the answer is D
Step-by-step explanation:
A line is passing through (0, 12), (8, 10), and (16, 8).
What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4 = (x – 6) and passes through the point (-2, -2)?
Answer:
y=x
Step-by-step explanation:
slope intercept form:
y= mx +c, where m is the gradient and c is the y-intercept.
Let's rewrite the given equation in the form of y=mx+c, so that we can determine the gradient of the line.
y-4= x-6
y= x -6 +4
y= x -2
Thus, the gradient of the given line is 1.
the product of the gradients of perpendicular lines is -1.
(gradient of line)(1)= -1
gradient of line= 1
Thus, m=1.
y= 1x +c
y= x +c
To find c, substitute a coordinate.
When x= -2, y= -2,
-2= -2 +c
c= -2 +2
c=0.
Thus the equation of the line is y=x.

Step-by-step explanation:

The types of statement can be used to explain the steps of a proof is postulate and theorem.
What is Theorem?A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument is used to prove a theorem by using the deductive system's inference rules to show that the theorem follows logically from the axioms and other theorems that have already been proven.
Guessing and Conjecture is just striking some ideas without any definite conclusion.
A claim that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block.
Thus, the statement used in proof is Postulate or Theorem.

The shipping box has a length of 30 inches and a height of 6 inches. How wide should the box be to fit the 36-inch bat? Show and explain your work.
Answer:
width = 18.97 inches
Step-by-step explanation:
To find the smallest width of the box to fit the bat, we need to put the bat in the diagonal of the box.
The diagonal of the box is given by:
diagonal^2 = length^2 + width^2 + height^2
Then, using the diagonal = 36 inches, length = 30 inches and height = 6 inches, we have:
36^2 = 30^2 + width^2 + 6^2
1296 = 900 + width^2 + 36
width^2 = 360
width = 18.97 inches
