Need help on this please
please help me please i really need help please
Answer:
Step-by-step explanation:
x + y = 1 -------------------(I)
5x + 3y = -3 -----------------(II)
Multiply (I) by (-5) -5x - 5y = -5
5x + 3y = -3 {Now add}
-2y = -8
y = -8/-2
y = 4
Plugin y = 4 in equation (I)
x + 4 = 1
x = 1 -4
x = -3
Solution: (-3, 4)
Pete read 2/5 of his book on the first day and 1/4 of his book on the second day. What fraction of the book Pete has left to read after two days of reading
=========================================================
Work Shown:
2/5 = 8/20 .... multiply top and bottom by 4
1/4 = 5/20 ..... multiply top and bottom by 5
The fractions 2/5 and 1/4 are equivalent to 8/20 and 5/20 in that order.
These new equivalent fractions add to 8/20+5/20 = (8+5)/20 = 13/20
After two days, Pete has read 13/20 of the book.
This leaves 1 - (13/20) = 20/20 - 13/20 = (20-13)/20 = 7/20 of the book left to be read.
Note how 13/20 + 7/20 = (13+7)/20 = 20/20 = 1

Eliminate the parameter in the equations x =t Superscript one-half and y = t – 4. How can the rectangular equation be described? cubic linear quartic quadratic
ANSWER: A
A function assigns values. The rectangular equation can be described as cubic.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As the function of x and y is given, therefore, if we eliminate t from both the function we will get,
[tex]x=t^{\frac12}\\\\x=\sqrt t\\\\x^2=t[/tex]
Now, substitute the value of t in the function of y,
[tex]y= t-4\\y=x^2-4[/tex]
Further, the rectangular equation can be written as,
[tex]\text{Rectangular Equation} = x \times y[/tex]
[tex]= x \times (x^2-4)\\\\= x^3-4x[/tex]
Thus, the rectangular equation can be described as cubic.

Find the value of x:
x^2 + 3x^3 - 2x + 9 = 24 + 54x + 92x^2 - 2x^3
Answer:
-91x² + 5x³ - 56x -15 = 0
Step-by-step explanation:
x² + 3x³ - 2x + 9 = 24 + 54x + 92x² - 2x³
x² + 3x³ - 2x + 9 - 92x² = 24 + 54x + 92x² - 2x³ - 92x²
-91x² + 3x³ - 2x + 9 + 2x³ = 24 + 54x -2x³ + 2x³
-91x² + 5x³ - 2x + 9 - 54x = 24 + 54x - 54x
-91x² + 5x³ - 56x + 9 - 24 = 24 - 24
-91x² + 5x³ - 56x -15 = 0

Answer:
Slope = (1/2)
Step-by-step explanation:
Rearrange the equation into the y = mx + b format.
-x + 2y = 5
2y = x + 5
y = (1/2)x + (5/2)
m represents slope, which is (1/2) in this question.

When x = -4, y = 2(-4)+2 = -6.
When x = -3, y = 2(-3)+2 = -4.
Fill in the other values of y the same way.
Answer:
(-4, -6)(-3, -4)(-2, -2)(-1, 0)(0, 2)(1, 4)(2, 6)Explanation:
y = 2x + 2
x: -4
y = 2(-4) + 2
y = -6
x: -3y = 2(-3) + 2
y = -4
x: -2y = 2(-2) + 2
y = -2
x: -1y = 2(-1) + 2
y = 0
x: 0y = 2(0) + 2
y = 2
x = 1y = 2(1) + 2
y = 4
x = 2y = 2(2) + 2
y = 6

The Rivertown city council is attempting to choose one of four sites (A, B, C, or D) as the location for its new emergency facility. After the new emergency facility becomes available for service, the current emergency facility will be shut down. The project manager has estimated the following response times in minutes from each of the proposed sites to the four areas that must be served by the emergency facility.
proposed-site Area-Served
1 2 3 4
A 5.2 4.4 3.6 6.5
B 6.0 7.4 3.4 4.0
C 5.8 5.9 5.9 5.8
D 4.3 4.8 6.5 5.1
The number of emergency runs from the current emergency facility to each of the four areas over the past year is as follows:
Area 1 2 3 4
Number-runs 150 65 175 92
Compute the weighted mean response time from the proposed locations and determine which proposed site should be selected for the new emergency facility.
a. site A
b. site B
c. site C
d. site D
Answer:
SITE A
Step-by-step explanation:
Given :
proposed-site Area-Served
1 2 3 4
A 5.2 4.4 3.6 6.5
B 6.0 7.4 3.4 4.0
C 5.8 5.9 5.9 5.8
D 4.3 4.8 6.5 5.1
Area 1 2 3 4
Number-runs 150 65 175 92
Computing the weighted average for the 4 sites :
Site A:
((150*5.2) + (65*4.4) + (175*3.6) + (92*6.5)) / (150 + 65 + 175 + 92)
= 2294 / 482
= 4.7593
Site B:
((150*6.0) + (65*7.4) + (175*3.4) + (92*4.0)) / (150 + 65 + 175 + 92)
= 2344/ 482
= 4.863
Site C:
((150*5.8) + (65*5.9) + (175*5.9) + (92*5.8)) / (150 + 65 + 175 + 92)
= 2819.6/ 482
= 5.850
Site D:
((150*4.3) + (65*4.8) + (175*6.5) + (92*5.1)) / (150 + 65 + 175 + 92)
= 2563.7/ 482
= 5.319
From the weighted average response time computed for the different sites ;
The best location for the emergency facility would be one with the least average response time; which is SITE A.
