Solve the following system.
y = -2x^2 + 3x - 1 and x + y = -1.
The solutions are
and
Given:
The equations of a system of equations are
[tex]y=-2x^2+3x-1[/tex]
[tex]x+y=-1[/tex]
To find:
The solution of the given system of equations.
Solution:
We have,
[tex]y=-2x^2+3x-1[/tex] ...(i)
[tex]x+y=-1[/tex] ...(ii)
Using (i) and (ii), we get
[tex]x+(-2x^2+3x-1)=-1[/tex]
[tex]x-2x^2+3x-1+1=0[/tex]
[tex]-2x^2+4x=0[/tex]
Taking out the common factors.
[tex]2x(-x+2)=0[/tex]
Using zero product property,we get
[tex]2x=0[/tex] and [tex]-x+2=0[/tex]
[tex]x=0[/tex] and [tex]2=x[/tex]
For x=0, we have
[tex]0+y=-1[/tex]
[tex]y=-1[/tex]
For x=2, we have
[tex]2+y=-1[/tex]
[tex]y=-1-2[/tex]
[tex]y=-3[/tex]
Therefore, the two solutions of the given system of equations are (0,-1) and (2,-3).
Which of the following rational functions is graphed below?
Answer:
B
Step-by-step explanation:
The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.

Kate writes an algebraic expression using each of the variables x and y only once. they first expression she writes uses x and y as factors. Than she writes another expression that uses x and y as terms. if x and y are both negative integers, write a comparison between the two expressions
Choice A: More information is needed.
Choice B: Using x and y factor results in an expression of greater value than using x and y as terms.
Choice C: None of the other answers are correct.
Choice D: The two expressions are of equal value.
Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.

Remy was on vacation in New France, Canada. He went to the Ratatouille restaurant and had an excellent dinner. How much did
he pay if the dinner cost $32 and he gave a 18% tip? How much was the tip?
Answer:
See both answers in the explanation
Step-by-step explanation:
Given data
Cost of dinner= $32
TIp=18%
Let us find the amount of the tip
=18/100*32
=0.18*32
=$5.76
Hence the total amount paid is
=5.76+32
=$37.76
The Tip is
=$5.76

Write the word sentence as an equation. Then solve the equation. A number $k$ increased by 7 is 34. An equation that represents this word sentence is . The solution is $k=$ .
Answer: k = 27
Step-by-step explanation:
Here's the complete question:
Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.
An increase in k simply means that there's an addition. This will be:
k + 7 = 34
k = 34 - 7
k = 27
Therefore, the value of k is 27

The length of a guys wire supporting a cell tower is 120 meters. The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower . To the nearest hundredth of a meter , how tall is the tower ?
Answer: 89.4427
Step-by-step explanation: I apologize if I am wrong; I used Pythagorean Thyreom, and I used the formula a=√c^2-b^2 since we are solving for side a.
a=√120^2−80^2
a=√14400−6400
a=√8000
a=89.4427

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the height of the tower is 89.44 m.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
The length of a guy's wire supporting a cell tower is 120 meters.
The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower.
We know that the Pythagoras theorem.
[tex]\rm H^2 = P^2 + B^2[/tex]
We have
H = 120 m
B = 80 m
Then by the Pythagoras theorem, we have
[tex]\rm P = \sqrt{H^2 - B^2}\\\\P = \sqrt{120^2 - 80^2}\\\\P = \sqrt{14400 - 6400}\\\\P = \sqrt{8000} = 89.44[/tex]
Thus, the height of the tower is 89.44 m.

Figure 2 of a tile pattern has 8 tiles, while figure 5 has 14 tiles. If the tile pattern grows at a constant rate, how many tiles will figure 40 have?
Answer:
84 tiles
Step-by-step explanation:
Given that :
Figure 2 = 8 tiles
Figure 5 = 14 tiles
Growth rate :
(Figure 5 - figure 2)x= 14 - 8
3x = 6
x = 6/3
x = 2
(Figure 40 - figure 2) = 38 * x
Initial number of tiles + 38x
8 + 38(2)
8 + 76
= 84
Figure 40 = 84 tiles
