If f(x) = 2 - x, express 2f(a) + f(2a) in simplest form.
Answer:
6 - 4a
Step-by-step explanation:
From the question given,
f(x) = 2 - x
2f(a) + f(2a) =.?
First, we shall obtain f(a). This can be obtained as follow:
f(x) = 2 - x
x = a
f(a) = 2 - a
Next, we shall obtain 2f(a). This is can be obtained as follow:
f(a) = 2 - a
2f(a) = 2(2 - a)
2f(a) = 4 - 2a
Next, we shall obtain f(2a). This can be obtained as follow:
f(x) = 2 - x
x = 2a
f(2a) = 2 - 2a
Finally, we shall determine 2f(a) + f(2a) as follow:
2f(a) = 4 - 2a
f(2a) = 2 - 2a
2f(a) + f(2a) =?
2f(a) + f(2a) = (4 - 2a) + (2 - 2a)
2f(a) + f(2a) = 4 - 2a + 2 - 2a
2f(a) + f(2a) = 4 + 2 - 2a - 2a
2f(a) + f(2a) = 6 - 4a
Therefore, 2f(a) + f(2a) is equivalent to 6 - 4a
A rectangle is 3 times as long as it is wide. The perimeter is 24 feet. Find the dimensions.
Answer:
Width is 3 units, The Length is 9 units.
Step-by-step explanation:
Three times as much as 3, or 9, is how you find the lengths. This being- 3+3=6 and 9+9=18, 6+18=24, which is the perimeter, therefore 3 and 9 are the dimensions.
What is the value of the expression below?
x/3+6=12
Answer:
x=108
Step-by-step explanation:
x/3+6=12 [tex]\frac{x}{3+6}=12[/tex]
1) 3+6=9
2) multiply both sides by 9
9x/9=12*9 [tex]\frac{9x}{9}=12*9[/tex]
3) Simplify
9x/9=x [tex]\frac{9x}{9}=x[/tex] (9 cancels out)
12*9=108
x=108
A gardener fills a 2 1/2 cubic foot wheelbarrow 2/3 of the way without soil weight 75.25 pounds. What is the weight of the soil un wheelbarrow?
Volume of wheelbarrow , V = 2 1/2 ft³ = 5/2 ft³.
Volume of soil in wheelbarrow , [tex]v = \dfrac{5}{3}\ ft^3[/tex] .
Mass of soil in wheelbarrow , m = 75.25 pounds.
Now, volume left , [tex]v'=\dfrac{5}{6}\ ft^3[/tex] .
Let, mass of soil un wheelbarrow is x.
[tex]x=\dfrac{\dfrac{5}{6}\times 75.25}{\dfrac{5}{3}}\\\\x=37.625\ pounds[/tex]
Hence, this is the required solution.
Given: f = {(0, 1), (2, 4), (4, 6), (6, 8)} and g = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} Complete the ordered pair below for the function shown.
f(x)
-----
g(x)
(4,__)
6/7
1
7/6
=======================================================
Explanation:
The given ordered pair is (4, ___) so we have x = 4 here.
We will plug this into f(x) and g(x) to get
f(4) = 6
g(4) = 7
So we have [tex]\frac{f(4)}{g(4)} = \frac{6}{7}[/tex]
-----------
If you're curious where f(4) = 6 came from, all we're doing is looking through the set of points
f = {(0, 1), (2, 4), (4, 6), (6, 8)}
to see which has 4 listed first as the x coordinate. That point is (4,6) so x = 4 leads to y = 6, ie, f(x) = 6 when x = 4. A similar situation happens with g(x) as well.

Find the sum of the first 80 terms of the sequence. Show all work for full credit. 1, -3, -7, -11, ...
Answer:
-12960
Step-by-step explanation:
The formula for the sum of terms =
Sn = n/2[2a + (n - 1) d]
n = number of terms = 80
The given sequence =
1, -3, -7, -11, ...
a = First term = 1
d = common difference
= Second term - First term
= -3 - 1
= -4
Therefore, the sum of the first 80 terms:
S80 = 80/2[2 × 1 + (80 - 1)]-4
= 40[2 + 79]-4
= 40 × 81 × -4
= -12960
The sum of the first 80 terms = -12960

Step-by-step explanation:
draw a flat shape that has no straight sides or angles
Answer:
try drawing a circle or an oval
Step-by-step explanation:
There are no edges or corners to a circle, ovals, or semicircles, making it a spherical form. Shapes may be categorized and sorted using these qualities as well as size.
What is a circle?A group of points that are all at the same distance from a fixed point is how it is characterized (called the center of a circle).
Ovals, semicircles, circles, and other closed forms all lack straight lines. Having one curved edge and one straight edge, a semicircle is a closed form.
An oval is a circle that has been flattened such that it resembles an egg or an ellipse: a mirror with an oval shape; a face with an oval shape. Ellipsoidal comparison.
By dividing a circle into two equal halves along the diameter line, a semicircle is created. There is just one line of symmetry in the semicircle, and that is the reflection symmetry. A half-disk is another name for the semicircle.
Thus, the flat shape that has no straight will be ovals, semicircles, and circles.

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.
Option A is the correct answer.
We have,
To solve the equation 3x + 7 = 16 - 2x for x, we need to isolate the variable x on one side of the equation.
Let's solve it step by step:
Start with the original equation:
3x + 7 = 16 - 2x
- Add 2x to both sides of the equation to get rid of the -2x on the right side: 3x + 2x + 7 = 16 - 2x + 2x
- Simplifying, we have: 5x + 7 = 16
- Next, subtract 7 from both sides of the equation to isolate the term with x: 5x + 7 - 7 = 16 - 7
- Simplifying, we have: 5x = 9
- Finally, divide both sides of the equation by 5 to solve for x: (5x)/5 = 9/5
- Simplifying, we have: x = 9/5
Therefore,
The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

10 POINTS : What is the solution to the equation 3/5x-6=-1/6x+7, rounded to three decimal places?
Answer:
x = 16.957
Step-by-step explanation:
(3/5)x - 6 = (-1/6)x + 7
Add (1/6)x to both sides. Add 6 to both sides.
(3/5)x + (1/6)x = 7 + 6
(18/30)x + (5/30)x = 13
(23/30)x = 13
Multiply both sides by 30/23.
x = 13/1 * 30/23
x = 390/13
x = 16.957
