Answer:
14 square units
Step-by-step explanation:
You need to know the formulas for the perimeter of a rectangle and the area of a rectangle, which are
2L + 2W - P where L is the length, W is the width, and P is the perimeter
and
A = LW
So we need to find the length and width to find the area
Step 1: Write equations out of the given information
"The length of a rectangle is 1 more than 3 times the width" can be rewritten as
L = 3W + 1
"the perimeter of the rectangle is 18 units" can be rewritten as
2L + 2W = 18
Step 2: Plug the first formula into the second one and solve
2(3W + 1) + 2W = 18
Simplify...
6W + 2 + 2W = 18
Combine like terms and subtract 2 from both sides
8W = 16
Divide both sides by 8 to isolate the W
W = 2
Step 3:
Plug W = 2 into the formula for L and solve for L
L = 3(2) + 1
L = 6 + 1
L = 7
Step 4: Use the length and width to calculate the area
A = LW
A = (7)(2)
A = 14 units squared

1 - The equation is:

Since it has no variable on exponents and it has a term with x to the second power, this is a quadratic function.
2 - <em>x</em> represents the length of the tomato patch, so if we want the area of the bell pepper patch, we can input x = 8 into the function:

Thus, the area is 16 square feet.
3 - Since the leading coefficient is negative, the vertex of the parabola gives the maximum value for the function.
The <em>x</em> value of the vertex is:

So, in this case:

And to find the value for the area, we need to input that into the function:

Thus, the maximum area is 18 square feet.
4 - The value for the length of the tomato patch is just the corresponding <em>x</em> for this maximum, which we calculated as the vertex <em>x</em>:

Thus, the length of the tomato patch for this maximum value is 6 feet.

Answer:
Rule is (x, y+k)
New point is (-3,9)
Step-by-step explanation:
A point translated vertically k units up means the x coordinate remains the same in the translation but the y coordinate is increased by k units
This can be represented mathematically as;
Let;s assume the point to be A with coordinates (x,y) then to get the image of the point under a vertical translation k units up you add k to the y coordinate value.
Given ;

where T is the translation
In the question
Given (-3,-6) and T is (0,5) the new coordinate will be

Triangle angles add up to a total of 180 degrees.
X will substitute for the second angle.
(X - 10) will substitute for the first angle, which is 10 less than the second angle (x).
The third angle is a right angle which is 90 degrees.
The equation therefore, the summation of the angles:
90 + x + (x - 10) = 180
Join like terms:
80 + 2x = 180
Solve for x:
2x = 100
x = 50
This means that:
The second angle is 50.
The first angle is 50 - 10 which is 40.
We can double check by adding the angles 50, 40, and 90 together to get 180.
