Answer:
x = [tex]\frac{y-1}{4}[/tex]
Step-by-step explanation:
Given
y = 4x + 1 ( subtract 1 from both sides )
y - 1 = 4x ( divide both sides by 4 )
[tex]\frac{y-1}{4}[/tex] = x

Joseph built a model of a pyramid where the base of the pyramid is a square. If the base has an area of 49 cm2 (squared), what is the side length of the base?
Answer:
7 cm
Step-by-step explanation:
We are told that the pyramid has a square base of an area of 49 cm².
Therefore, the side length of the base of the pyramid is still the same as the side length of a square having an area of 49 cm².
Area of a square = s², where s is the side length of the square.
The side length of the base can be gotten using the following equation,
[tex] s^2 = 49 [/tex]
Solve for s by looking for the share root of both sides.
[tex] \sqrt{s^2} = \sqrt{49} [/tex]
[tex] s = 7 [/tex]
The side length of the base = 7 cm

Point P is located at (-3,5)
Point P' is the image of P after a translation three units to the left, then a reflection using the x-axis.
Find the coordinates of P'
Answer:
P' (- 7, - 5 )
Step-by-step explanation:
A translation of 3 units to the left means subtractin 3 from the x- coordinate with no change to the y- coordinate, thus
P(- 3, 5 ) → (- 3 - 4, 5 ) → (- 7, 5 )
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(- 7, 5 ) → P'(- 7, - 5 )

Answer:
Solution : 29
Step-by-step explanation:
As this is an equilateral triangle all sides present are congruent.
3x + 8 = 5x - 6 = 2x + 15
3x + 8 = 5x - 6
- 2x = - 14,
x = 7
And hence one side length will be say 3(7) + 8 = 21 + 8 = 29 units. We can double check this solution by substituting x for other side lengths. Remember that all the side length have an equal measure.
5(7) - 6 = 35 - 6 = 29 ✓
2(7) + 15 = 14 + 15 = 29 ✓
If f(x) = 2x + 7 and g(x)= 3x² -1, what expression represents (f(g(x)) ?
A 6x2 +5
B 6x2 +12
C 3x2 - 2x -8
D 3x2 + 2x + 6
Answer:
A. 6x^2+5
Step-by-step explanation:
The expression that represents the function (f(g(x))) is 6x² + 5, option A is correct.
Given expressions are f(x) = 2x + 7 and g(x) = 3x² - 1
To find (f(g(x))), we substitute g(x) into f(x):
f(g(x)) = 2(g(x)) + 7
Substituting g(x) = 3x² - 1:
f(g(x)) = 2(3x² - 1) + 7
Distributing the 2:
f(g(x)) = 6x² - 2 + 7
Combining like terms:
f(g(x)) = 6x² + 5

Use the key features of the polynomial f(x) = 6x^4 + 4x^3 - 5x^2 -2x + 1 to describe its end behavior. A. The left side continues up, and the right side continues up. B. The left side continues down, and the right side continues down. C. The left side continues up, and the right side continues down. D. The left side continues down, and the right side continues up.
Answer:
A. The left side continues up, and the right side continues up.
Step-by-step explanation:
f(x) = 6x^4 + 4x^3 - 5x^2 -2x + 1
The highest power will describe the end behavior
f(x) = 6x^4
Let x = -∞
f(-∞) = 6 * (-∞)^4 = 6* ∞ = ∞
As x goes to -∞ f(x) goes to ∞
Let x = ∞
f(∞) = 6 * (∞)^4 = 6* ∞ = ∞
As x goes to ∞ f(x) goes to ∞

Help please, -16-4g=6g-6g?
Answer:
the answer is -4
Step-by-step explanation:
-16-4g=6g-6g
+4 +4
you add the -4g to both sides by changeing it to positive
then you have -16=6g-2g
then you go to the right side of the equation and solve, 6-2 is 4 then you have
-16=4g then you divide on both sides
-16 divided by 4 is
-4
Answer:
[tex]\Huge \boxed{g=-4}[/tex]
Step-by-step explanation:
[tex]-16-4g=6g-6g[/tex]
Combining like terms.
[tex]-16-4g=0[/tex]
Adding 4g to both sides.
[tex]-16=4g[/tex]
Dividing both sides by 4.

Hey there!
Functions are basically like machines you put a number into and they give you a new one as an output. This f represents this machine. f(x) represents whatever the output is because it is the x after it has gone through the function machine.
We want to figure out what x is when f(x)=12. Well, we can simply replace f(x) with 12 in the first equation and solve for x!
12=-16x+8
We flip the equation so x is on the left side.
-16x+8=12
We subtract 8 from both sides.
-16x=4
We divide both sides by -16.
x=-1/4
Have a wonderful day! :D
Answer:
f(x) = -16x + 8
F(x) = 12
=> f(12) = -16x + 8
=> 12-8 = -16x + 8 - 8
=> 4 = 16x
=> 4/16 = 16x/16
=> 1/4 = x
So, the answer is 1/4.

Olivia is tracking the growth rate of a population of termites, x, living in a mound. When the population is x = 400, it is the 0th hour. Initially, it takes f(x) = 1 hour for the population to grow by 400 termites. When the population grows by another 400 termites, the total time taken is f(x) = 1.585 hours. The time taken keeps decreasing to model the same incremental growth. Does the equation for f(x) or the graph of g(x) correctly model the situation?
Answer:
Based on the information in the problem statement, the function must pass through points (400 , 0), (800 , 1), and (1,200 , 1.585). Notice that the graph of function g(x) passes through these points.
Next, check the graph of f(x). Plot the function using the given equation to see which points it passes through.
The equation indeed starts at (400 , 0), but it doesn’t pass through the other two required points. So, the graph of g(x) fits the situation, but the equation for f(x)does not.

No. of days Amount earned
1 1
2 4
3 9
4 16
. .
. .
. .
30 500,000
To find a function to the story
Let
No. of days = d
Amount earned = A
When,
d=1, A=1
d=2, A=4
d=3, A=9
d=4, A=16
It can be seen that amount earned is a square of the number of days
Therefore,
The function for the story is:
A=d^2
When d=30
A=30^2
=30*30
=900
Adding the total earnings for 30 days=$500,000
That is
1+4+9+16+25+36+49+64+81+100+121+144+169+196+225+256+289+324+361+400+441+484+529+576+625+676+729+784+841+900=500000

A bag contains 7 red marbles and 4 blue marbles.
A marble is taken at random from the bag and replaced.
Another marble is taken from the bag.
Work out the probability that the two marbles
taken from the bag are the same colour.
Answer:
calculate the probability that the marbles are the same color, then subtract this probability from 1 to find the probability they are different colors. P(2 of the same) = P(2 green) + P(2 yellow) + P(2 red) = 1/26 + 5/26 + 2/26 = 8/26 = 4/13. P(2 different) = 1 - P(2 of the same) = 1 - 4/13 = 9/13.

If $(ax+b)(2x+3)=20x^2+44x+21$, where $a$ and $b$ are two distinct integers, what is the value of the sum $a+b$?
Answer: 17
Step-by-step explanation:
Given: [tex](ax+b)(2x+3)=20x^2+44x+21[/tex], where a and b are two distinct integers.
First simplify left hand side as
[tex](ax+b)(2x+3)=ax\cdot \:2x+ax\cdot \:3+b\cdot \:2x+b\cdot \:3\\\\=2axx+3ax+2bx+3b\\\\=2ax^2+(3a+2b)x+3b[/tex]
Then comparing left side and right side
[tex]2ax^2+(3a+2b)x+3b=20x^2+44x+21[/tex]
we get 2a = 20 (coefficient of [tex]x^2[/tex]) , and 3b = 21 (constant term)
⇒ a= 10 and b= 7
Then, a+b= 10+7=17
Hence, the value of sum a+b is 17.
A recipe calls for 2 cups of sugar, 2 eggs, 3 cups of flour, and 5 cups of milk. What is the ratio of sugar to flour?
Answer:
2 cups of sugar:3 cups of flour
Step-by-step explanation:
Because there are 2 cups of sugar and 3 cups of flour used, you can represent this with a ratio - 2 cups sugar:3 cups flour.
Because 2:3 cannot be reduced (it is in its simplest form), this is the final answer.
