You should plug the numbers into the quadratic formula to get the answer.
Answer:
A: -5 ± √ 17 / 2
Step-by-step explanation:
Consider the following equations:
ax^2 + bx + c - This is an equation you use in understanding quadratic functions.
x= (−b± √b^2−4ac) / 2a - This is the quadratic formula used to solve quadratic functions
So: ax^2 + bx + c = x^2 + 5x + 2
SOLVE:
-(5) ± √ 5^2−4(1)(2)) / 2(1)
= -5 ± √ 25− 8 / 2
= -5 ± √ 25− 8 / 2
= -5 ± √ 17 / 2

- Functions F and A are defined by these equations below. Which function has a greater value when x is 2.5?
A. F(x) = 80-15x
B. A(x) = 25 + 10x
Answer:
The answer is D- A(x)=25+10x
Step-by-step explanation:
I cant really explain how i got the answer but i got it right
The function A(x) has greater value then F(x) for x = 2.5.
What is a function?A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one.
Given are two functions of [x] as follows -
F(x) = 80 - 15x
A(x) = 25 + 10x
We have the following functions -
F(x) = 80 - 15x
A(x) = 25 + 10x
Now, we will evaluate each function at x = 2.5.
F(2.5) = 80 - 15 x 2.5 = 42.5
and
A(2.5) = 25 + 10 x 2.5 = 50
It can be seen that A(2.5) > F(2.5)
So, the function A(x) has greater value then F(x) at x = 2.5
Therefore, the function A(x) has greater value then F(x) for x = 2.5.

Solve the system of equations using elimination
Answer:
(1, 3).
Step-by-step explanation:
x + 2y = 7
3x - 2y = -3
Adding the 2 equations will eliminate y:
4x = 4
x = 4/4
x = 1
Plug x = 1 into the first equation:
1 + 2y = 7
2y = 6
y = 3.

Answer: (a + 2)(a - 2) which is the first answer choice
=========================================================
Explanation:
Use the difference of squares factoring rule which is x^2 - y^2 = (x+y)(x-y)
In this case, x = a and y = 2
x^2 - y^2 = (x+y)(x-y)
a^2 - 2^2 = (a+2)(a-2)
a^2 - 4 = (a+2)(a-2)

If the Pixie Sticks cost 4.50 per pound and Nicholas spends 8.10, How many pounds did he purchase?
Answer:
Step-by-step explanation:
Nicholas has purchased 1.8 pounds of pixie sticks.
Jane has purchased 3.0 pounds of Jolly ranchers.
Step-by-step explanation:
Cost of 1 pounds of pixie sticks = $4.50
Let the number of pixie sticks = x
Total money spend on x pounds of pixie sticks = $8.10
Nicholas has purchased 1.8 pounds of pixie sticks.
Cost of 1 pounds of Jolly ranchers = $3.25
Let the number of Jolly ranchers = y
Total money spend on y pounds of Jolly ranchers = $9.75
Jane has purchased 3.0 pounds of Jolly ranchers.

what is j+m, j times m and j divided by m
Answer:
j + m
jm
[tex]\frac{j}{m}[/tex]
Step-by-step explanation:
We have j and m and are asked to add, multiply and divide them both.
When it comes to adding, its all about like terms, if the terms are not alike meaning ending in the same variable they cannot be added.
Therefore j + m is equal to just j + m.
Now for multiplying, this is free rule, you can freely multiply any variable you want without reprecussion.
Therefore, j * m is equal to jm.
Now for dividing, this works like adding, where you can divide only if the terms are the same, since j and m are not the same. J divided by M is equal to [tex]\frac{j}{m}[/tex]

[tex]Length = 13.5in[/tex]
[tex]Width = 2.5in[/tex]
[tex]Height = 8in[/tex]
Required
The total surface area (TSA)
This is calculated as:
[tex]TSA = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
[tex]TSA = 2 * (13.5 * 2.5 + 13.5 * 8 + 2.5 * 8)[/tex]
