(5x + 1)(5x - 1)
Answer:
25x² - 1
Step-by-step explanation:
Given
(5x + 1)(5x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 1) + 1(5x - 1) ← distribute both parenthesis
= 25x² - 5x + 5x - 1 ← collect like terms
= 25x² - 1
find the y-intercept and slope of the function’s graph, and find the equation for the function using the table in the picture.
y- intercept:
slope:
equation:
m = (y2-y1)/(x2-x1)
m = (9-5)/(3-2)
m = 4
Substitute the values in y= mx + c,
5 = (4)(2) + c
5 = 8 + c
c = -3
Thus, the equation is y= 4x -3
The y intercept is -3 and the slope of line is 4 .
Then the equation of line will be : y= 4x -3
Given,
Points on x and y axis .
Standard equation of line :
y = mx + c
m = slope of line
c = y intercept
Now
Firstly find out the slope of line ,
m = (y2-y1)/(x2-x1)\
m = (9-5)/(3-2)
m = 4
Now to calculate the value of y intercept
Substitute the values in y= mx + c,
5 = (4)(2) + c
5 = 8 + c
c = -3
Thus, the equation is m = (y2-y1)/(x2-x1)

Given that 2x + 1 =5, what is the value of (x+3)^3
Answer: 125
Step-by-step explanation:
First, solve for x in the first equation.
1) Subtract 1 from both sides.
2x = 4
2) Divide by 2 on both sides.
x = 2
Next, substitute the value of x into the second expression.
(2 + 3)^3
= 5^3
= 125
Answer:
The value of (x + 3)³ is 125.
Step-by-step explanation:
First, we have to find the value of x.
To do so, start with the first equation, 2x + 1 = 5.
We can easily solve this equation to find the value of x.
First, start by subtracting 1 from each side.
This leaves us with 2x = 4.
Next, divide by two on each side.
This will leave us with the answer x = 2.
Now we know the value of x = 2.
All that's left to do is substitute the value of x, 2, for x.
First, start with the second equation (x + 3)³.
We know that x is equal to 2, so we can enter 2 for x.
We then have the equation (2 + 3)³.
Next, solve.
Add the 2 and the 3 together.
Now, the equation is 5³.
5³ is equal to 5 · 5 · 5
5 · 5 · 5 = 125
To sum up,
We found out that x = 2
Using 2 for x, we found out that (x + 3)³ is equal to 125.
use the graph shown to complete the following sentence. when x = -3, then y = ___.
Answer:
y = -6
Step-by-step explanation:
We are trying to find the y-value when x = -3.
We see from our graph and linear equation that when x = -3, y = -6.
Therefore, our answer is -6.

Dom:
Range:
Function?
Answer:
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
The relation R is not a function
Step-by-step explanation:
Relations and Functions
We are given the ordered pairs of a relation, let's call it R:
R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}
The domain of R is the set of values that relate to 1 or more elements from the range.
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.
A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.
The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)
map the element -3 twice.

The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2½ = 2.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
The perimeter of a parallelogram can be obtained by using the following formula:
Perimeter = 2(a + b)
Thus, with the above formula, we can obtain the value of y as shown below:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
Perimeter = 2(a + b)
Perimeter = 2a + 2b
129 = 2(10y – 9) + 2(17y + 6)
Clear bracket
129 = 20y – 18 + 34y + 12
Collect like terms
129 + 18 – 12 = 20y + 34y
135 = 54y
Divide both side by the coefficient of y i.e 54
y = 135/54
y = 2½ = 2.5
Thus, the value of y is 2½ or 2.5
Solve the equation and enter the value of x below.
