Evaluate the equation for the indicated value, f(n)=5n+8 for f(4),
The value of the function f(n)=5n+8 for f(4) will be 28.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given function is f(n)=5n+8. The value of the function at equal to 4 will be calculated as below:-
f(n)=5n+8
f(4) = ( 5 x 4 + 8 )
f(4) = 20 + 8
f(4) = 28
Therefore, the value of the function f(n)=5n+8 for f(4) will be 28.

Are the triangles PQR and RST similar why or why not?
Answer: The triangles are similar
======================================================
Explanation:
The square markers show that
angle RPQ = angle RST = 90 degrees
So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.
Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.
Answer:
Triangle PQR and RST are both right triangles but they do not share the same side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

Which graph best represents the equation y=2x+5?
Answer:
B?
Step-by-step explanation:
The graph y = 2x + 5 can be represented by the image attached below.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, An equation y = 2x + 5, we can graph this by assuming some arbitrary values of 'x' that correspond to some arbitrary values of 'y'.
When x = 0, y = 5.
x = 1, y = 7 ⇒ (1, 7).
x = 5, y = 15 ⇒ (5, 15).
x = - 5, y = - 5 ⇒ (- 5, - 5).
x = - 2, y = 1 ⇒ (- 2, 1).

Answer:wait 15 min then I will have thee answer
Step-by-step explanation:
Please help me, linear equations. Hurry please :)
Answer:
C) 18
Step-by-step explanation:
All you have to do is solve the equation.
2.25x + 5 = 45.50 (subtract 5 on each side)
2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)
x = 18
40.50/2.25 = 18
Answer:
18 Miles
Step-by-step explanation:
If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.
Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

What is the approximate
distance between points
(-7, 2) and (11,-5)?
a) 18.36 units
b) 19.31 units
c) 18.25 units
d) 10.31 units
e) 8.06 units
9514 1404 393
Answer:
b) 19.31 units
Step-by-step explanation:
The distance formula is useful for this.
d = √((x2 -x1)² +(y2-y1)²)
d = √((11 -(-7))² +(-5-2)²) = √(18² +(-7)²) = √373
d ≈ 19.31 . . . units
log4 (3x – 1) = log4 (x + 5) Solve the equation
Answer:
x = 3.
Step-by-step explanation:
log4 (3x - 1) = log4 (x + 5) Since they are both logs to the base 4:
3x - 1 = x + 5
2x = 6
x = 3.
On solving the logarithmic equation, we find that x = 3.
What are logarithmic equations?A logarithmic equation is an equation that involves the logarithm of an expression containing a variable.

Step-by-step explanation:
This table displays the amount of water in a bathtub as it is being drained.
A 2-column table with 4 rows. Column 1 is labeled Time (minutes) with entries 7, 8, 9, 10. Column 2 is labeled Water (gallons) with entries 38.5, 36.25, 34, 31.75.
Use the table to interpret the rate of change.
What is the rate of change for the relationship?
Answer:
i know its late but its -2.25 if you still need it
Step-by-step explanation:
just did it on edge
The rate of change for the relationship, given the data, is -2.25 gallon/min
What is velocity?Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:
Velocity = displacement / time
With the above idea in mind, we can obtain the rate of change for the given relationship.
How do determine the rate of change?Column 1 i.e time (min) = 7, 8, 9, 10.
Column 2 i.e Water (gallons) = 38.5, 36.25, 34, 31.75.
What is the formula for the Rate of change?Rate = Change in gallon/change in time
Rate = (36.25 - 38.5) / (8 -7)
Rate = -2.25 / 1
Rate of change = -2.25 gallon/min

Write the equation of the line perpendicular to y=4x+2 and passes though the point (1,1).
Answer:y=-1/4x+5/4
Step-by-step explanation:
Perpendicular means the slope has to be the negative reciprocal.
Since the slope is currently 4, the perpendicular slope is -1/4.
It also has to pass through the point 1,1 , so you just plug x in which will be
1*-1/4=-1/4. from 1 to -1/4, its 5/4, so that's your b in y = mx+b
The equation will then be y=-1/4x+5/4
