PLEASE PLEASE HELP, I AM TIMED! What is the equation to the function? Explain.
Answers
Step-by-step explanation:
General equation: y = 2 + c/(x - 1)
When x = 4, y = 4.
=> (4) = 2 + c/(4 - 1), c = 6.
Hence the equation is y = 2 + 6/(x - 1).

solve the square root of 2x-5=x-4
Answers
Simplifying
2x + -5 = x + -4
Reorder the terms:
-5 + 2x = x + -4
Reorder the terms:
-5 + 2x = -4 + x
Solving
-5 + 2x = -4 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
-5 + 2x + -1x = -4 + x + -1x
Combine like terms: 2x + -1x = 1x
-5 + 1x = -4 + x + -1x
Combine like terms: x + -1x = 0
-5 + 1x = -4 + 0
-5 + 1x = -4
Add '5' to each side of the equation.
-5 + 5 + 1x = -4 + 5
Combine like terms: -5 + 5 = 0
0 + 1x = -4 + 5
1x = -4 + 5
Combine like terms: -4 + 5 = 1
1x = 1
Divide each side by '1'.
x = 1
Simplifying

Write the equation for the line with the given points (0,-3) and (2,9) in point slope form

First of all, we will solve for our M which is our slope.
M = Yb - Ya / Xb - Xa
M = 9 - (-3) / 2 - 0
M = 9 + 3 / 2 - 0
M = 12 / 2
M = 6
Now that we have our slope, we will be finding our y-intercept.
Y = mx + b
9 = (6)(2) + b
9 = 12 + b
= 9-12 = 12-12 + b (12 cancels out)
= -3 = b
So, therefore, the equation is: Y = 6x - 3

Find out how many stamps and coins Jackie has. Part A: Write let statements that represent the variables in this situation (2 points) Part B: Set up a system of equations that you can use to solve this problem? (2 points) Part C: Solve the system from (b) by using either substitution or elimination *show all solving steps*. (4 points) Part D: Write a solution statement answering the question
Answers
Answer:
Jackie collected 61 coins and 20 stamps
Step-by-step explanation:
Solving (a): Variable representation
Let the coins be represented with c
Let the stamps be represented with s
Solving (b): Setup equation
Total is 81. This implies that:
[tex]s + c = 81[/tex]
Also:
[tex]c = 1 + 3s[/tex]
Solving (c): Solve the system
Substitute 1 + 3s for c in [tex]s + c = 81[/tex]
[tex]s + 1 + 3s = 81[/tex]
Collect Like Terms
[tex]s + 3s = 81-1[/tex]
[tex]4s= 80[/tex]
Divide both sides by 4
[tex]s = \frac{80}{4}[/tex]
[tex]s= 20[/tex]
Substitute 20 for s in [tex]c = 1 + 3s[/tex]
[tex]c = 1 + 3 * 20[/tex]
[tex]c = 1 + 60[/tex]
[tex]c = 61[/tex]
Solving (d): Solution statement

An airplane is flying from knoxville to new york. The distance it travels in miles, d, is related to the time in seconds, t, by the equation: d=0.12t. How many miles is it flying per second?
Answers
Answer:
0.12 miles is it flying per second.
Step-by-step explanation:
The distance d is related to time t in seconds is given by the equation as follows :
d =0.12 t
We need to find how many miles is it flying per second.
[tex]\dfrac{d}{t}=0.12\\\\\dfrac{\text{miles}}{\text{second}}=0.12[/tex]
So, the speed of the airplane is 0.12 miles per second, Hence, 0.12 miles is it flying per second.

Which value of x is a solution of the inequality 25x - 100 < 250?
Answers
Answer:
inequality form: x<14
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
The solution of the given inequality is set of all x such that x < 14.
What are Inequalities?Two or more expressions connected with symbols of inequality like ≥, ≤, > and < is called the inequalities.
There are different kinds of inequalities like polynomial inequalities which includes linear inequalities and quadratic inequalities, rational inequality and so on.
Linear inequalities will have the highest degree of the variable equals 1.
Given a linear inequality,
25x - 100 < 250
Adding both sides of the inequality with 100,
25x - 100 + 100 < 250 + 100
25x < 350
Dividing both sides of the inequality by 25,
25x / 25 < 350 / 25
x < 14
Hence the value of x in the inequality is all the values of x which are less than, < 14.

The distance a coiled spring stretches varies directly with the amount of weight hanging on the spring. If a spring stretches 2 cm when a 30 gram weight is hung from it, how far will it stretch when a 75 gram weight is hung from the spring?
Answers
Answer:
5 cm
Step-by-step explanation:
The distance a coiled spring stretches varies directly with the amount of weight hanging on the spring.
Distance = D
Weight = W
Hence:
D ∝ W
D = kW
Where k is constant of proportionality
Step 1
We solve for k
If a spring stretches 2 cm when a 30 gram weight is hung from it.
2 = 30k
k = 2/30
k = 1/15
Step 2
how far will it stretch when a 75 gram weight is hung from the spring?
D = kW
We are solving for D
k = 1/15
D = 1/15 × 75
D = 5 cm
The spring would stretch 5cm with a weight of 75 gram.

Answer:

Step-by-step explanation:
The imaginary part of the complex number is -7/2.
What is complex form?A complex number can be expressed in the polar form in addition to the rectangular form. Complex numbers are typically expressed as z = x + iy, where 'i' is a fictitious integer. Complex numbers are described as a union of argument and modulus in polar form, however.
We know a complex form,
a + bi, where the coefficient of 'i' is the imaginary part and the rest of the part is a real part
So,
[tex]\frac{1}{2} + (\frac{-7}{2} )i[/tex]
Compared to the standard form,
-7/2 is the imaginary part.
Therefore, -7/2 is the imaginary part.
