Answer:
See below
Step-by-step explanation:
It seems to be a typo.
[tex]f(x)=2x-31+2[/tex]
[tex]f(x)=2x-29[/tex]
The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.
[tex]0=2x-29[/tex]
[tex]x=\dfrac{29}{2}[/tex]
Once there are alternatives with two values, your function is probably a quadratic function.
[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.

Parker the dog is 2 feet 6 inches long. There are 2.54 centimeters in 1 inch. How many centimeters is Parker the dog?
Answer:
Parker the dog is 76.2 centimeters long.
Step-by-step explanation:
Parker the dog is 2 feet 6 inches long. There are 2.54 centimeters in 1 inch. How many centimeters is Parker the dog? 2 feet = 12 inches. 2(12) + 6 = 30
30(2.54) = 76.2.
Please let me know if you have anymore questions.
Good Luck! :)
1 foot = 12 inches
1 inch = 2.54 centimeters
1 foot = 30.48 centimeters
2 x 30.48 = 60.96
6 x 2.54 = 15.24
60.96+15.24=76.20
Parker the Dog is 76.20 centimeters tall.

What is the value of the expression 5y² + 4x when x = 2.5 and y = 3?
Answer:
55
Step-by-step explanation:
the value of the expression 5y² + 4x when x = 2.5 and y = 3 will be 55.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given an expression 5y² + 4x
To calculate the value of expression at x = 2.5 and y = 3
Substitute the value of x and y in the expression:
=> 5y² + 4x
=> 5* 9 + 4 * 2.5
=> 45 + 10
=> 55
therefore, 55 is the value of the expression 5y² + 4x when x = 2.5 and y = 3.

We must use slope formula* to solve this.

What is the equation of the line parallel to 8x−16y=−14 and passing through (3,0)?
6x−12y=18
6x+12y=18
12x−6y=−18
12x+6y=18
Answer:
2y = x - 3
Step-by-step explanation:
Parallel lines can be defined as lines that do not intersect and as a result of this, parallel lines have the same slope but different intercepts.
Given the following data;
Points (x, y) = (3, 0)
Equation is 8x - 16y = -14
To find the equation of the line?
First of all, we would have to determine the slope of the line;
y = mx + c ......equation 1
8x - 16y = -14
Rearranging the equation, we have
16y = 8x + 14
Dividing through by 16, we have;
y = 8/16(x) + 14/16
y = 1/2(x) + 7/8
Therefore, the slope, m is 1/2
*To find the intercept*
Since the line is parallel we would use, m = 1/2
Substituting the values into equation 1, we have;
y = mx + c for x = 3 and y = 0
0 = 1/2(3) + c
c = -3/2
Re-writing the equation of line;
Slope, m = 1/2
Intercept, c = -3/2
y = 1/2(x) + (-3/2)
Multiplying all through by the lowest common denominator "2"
2y = x - 3

4y - 9 - 6y = 2(y + 5) - 3 solve for y
Answer:
[tex] \huge{ \boxed{ \bold{ \tt{y = - 4}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4y - 9 - 6y = 2(y + 5) - 3}[/tex]
Subtract like terms : 6y from 4y
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2(y + 5) - 3}}[/tex]
Distribute 2 through the parentheses
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2 *y + 2 *5 \: - 3}}[/tex]
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2y + 10 - 3}}[/tex]
Subtract 3 from 10
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2y + 7}}[/tex]
Move 2y to left hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 2y - 2y - 9 = 7}}[/tex]
Move 9 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 2y - 2y = 7 + 9}}[/tex]
Combine like terms
[tex] \longrightarrow{ \sf{ - 4y =7 + 9}}[/tex]
Add the numbers : 7 and 9
[tex] \longrightarrow{ \sf{ - 4y = 16}}[/tex]
Divide both sides by -4
[tex] \longrightarrow{ \sf{ \frac{ - 4y}{ - 4} = \frac{16}{ - 4}}} [/tex]
Remember : Dividing a positive integer by any negative integer gives a negative integer.
[tex] \longrightarrow{ \boxed{ \sf{y = - 4}}}[/tex]
------------------------------------------------------------
Let's check whether the value of y is -4 or not.
VerificationL.H.S : [tex] \sf{4y - 9 - 6y}[/tex]
plug the value of y and simplify
[tex] \dashrightarrow{ \sf{4 * (- 4 )- 9 - 6 * (- 4)}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 - 9 - ( - 24)}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 - 9 + 24}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 + 15}}[/tex]
[tex] \dashrightarrow{ \sf{ - 1}}[/tex]
R.H.S :[tex] \sf{2(y + 5) - 3}[/tex]
plug the value of y and simplify
[tex] \dashrightarrow{ \sf{2( - 4 + 5) - 3}}[/tex]
[tex] \dashrightarrow{ \sf{2 *1 - 3}}[/tex]
[tex] \dashrightarrow{ \sf{2 - 3 }}[/tex]
[tex] \dashrightarrow{ \sf{ - 1}}[/tex]
∴ L.H.S = R.H.S
The value of y is -4
And we're done!

What is the solution to the inequality 75 > x/15?
______________________________________
A) x 1,125
C) x 5
______________________________________
Answer:
75 > x/15
Step-by-step explanation:
Step 1: Mulitply the 15 on both sides in order to get the x by it self.
Step 2: Simplify. 75 x (15) >x/15 x (15)
Step 3: The 15 on the right hand side cancels out leaving the x by itself.
Final Answr: 1125 > x which translates to x < 1125
The solution to the inequality is: A) (x > 1125)
To solve the inequality 75 > x/15, we need to find the range of values for x that satisfy the inequality.
First, we can start by isolating x on one side of the inequality. To do that, we can multiply both sides of the inequality by 15 (since 15 is a positive number, we don't need to reverse the inequality sign):
75 * 15 > x
Now, simplify the left side of the inequality:
1125 > x
So, the solution to the inequality is x < 1125, which means all values of x that are less than 1125 will satisfy the inequality.
Visually, if we plot the graph of y = x/15 and y = 75, we'll see that y = x/15 is a straight line with a positive slope of 1/15 passing through the origin, and y = 75 is a horizontal line parallel to the x-axis at the y-coordinate of 75. The solution to the inequality is the region below the line y = 75, which corresponds to the values of x that are less than 1125.
In real-world terms, this inequality represents a scenario where 75 is greater than some fraction of x divided by 15. To satisfy the inequality, x must be less than 1125. For example, if x represents the number of items sold in a store, this inequality would indicate that the store must sell fewer than 1125 items to meet the condition. The store's sales would need to be less than 1125 * 15 = 16,875 to maintain the inequality's validity. Beyond this point, if the store sells more items, the inequality would no longer hold true.
