Answer:
1) x<2.5 2) x<2.5 (both are smaller numbers than 2.5)
Step-by-step explanation:
I'm sure there is a easier way to figure this question out but how I did is by simply imputing numbers smaller or bigger into where the x is. For example, I imputed 3 into -4x+5>-5. So, -4(3)+5>5, = -7>5, this is false, so x must be smaller than 2.5 in order for this to be true.

The answer is c
Step-by-step explanation: Since both terms are perfect squares, factor using the difference of squares formula to get the answer i hope this helps
Hey there!
The answer is C.
To factor an expression, you take the root (same as exponent variable has) of the terms and put them into parantheses. We can also check the choices to see if they're correct by solving them.
A is incorrect, because if you solve it, you would have [tex]x^2-121[/tex]
B is incorrect, because if you solve it, you would have [tex]121x-x^2[/tex]
C is correct, because if you solve it, you would have [tex]121-x^2[/tex]
D is incorrect, because it CAN be factored.

What is the area of this parallelogram
Answer:
B. 12.25
Step-by-step explanation:
A=bxh=3.5·3.5=12.25
Answer:
17.15
Step-by-step explanation:
There are 2 ways to solve this.
One way is this:
Add 1.4 and 3.5 together to get the total length of the parallelogram. The sum would be 4.9. Then multiply this number by the height of the figure(3.5cm). So that the product of 4.9 and 3.5 is 17.15.
The second way is this:
Find the area of the two triangles and the square and then add those products together. So add:
1.4 x 3.5 ÷21.4 x 3.5 ÷23.5 x 3.5So solve this equation and you will get:
2.45 + 2.45 + 12.25=17.15What is the equation of the line that passes through the point (−1,−1) and has a slope of −6?
Answer: y= -6x -7
Step-by-step explanation:
Point slope formula : y-y1=m(x-x1)
y- (-1)=-6(x- (-1))
y+1= -6(x+1)
y+1= -6x-6
y+1-1=-6x-6-1
y=-6x-7

Over what range of pages will Edie pay less by using the first printer ? A. Less than 100 pages B. More than 100 pages C. Less than 50 pages D. More than 50 pages E. More than 100 pages but less than 200 pages
Answer:
A) less than 100 pages
Step-by-step explanation:
p = # pages
Printer 1:
y = .25p + 5
Printer 2:
y = .20p + 10
.25p + 5 < .20p + 10
.05p + 5 < 10

Use the Remainder Theorem to evaluate f(10) for:
f(x) = 2x^3 – 14x^2 - 56x - 40
Step-by-step explanation:
Since we are told that 10 is a zero,
(x−10) must be a factor:
F(x)=2x3−14x2−56x−40
F(x)=(x−10) (2x2+6x+4)
F(x)=2(x−10)(x2+3x+2)
F(x)=2(x−10)(x+2)(x+1)
So the other two zeros are
x = -2 and x= −1

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]

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.
- 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.

Step-by-step explanation:
Given
[tex]AO = 5x - 1[/tex]
[tex]BO = 4x + 9[/tex]
Required:

Express the function h(x)= 1/x-6 in the form of f o g. If g(x)=(x-6), find the function f(x).
Answer:
f(x) = 1/x
Step-by-step explanation:
h(x) = f(g(x)) = f(x-6) = 1/x-6
1/x-6 could only be accomplished if f(x) = 1/x
Assuming f(x) = 1/x and g(x) = x-6, f(g(x)) = f(x-6) = 1/x-6
Since f(g(x)) = 1/x-6 = h(x), we've proven that f(x) = 1/x.
The given functions are illustrations of a composite function, where the function f(x) is:
[tex]f(x) = \frac{1}{x}[/tex]
Given that:
[tex]h(x) = \frac{1}{x - 6}[/tex]
[tex]g(x) = x - 6[/tex]
f o g can be written as f(g(x))
So, we have:
[tex]h(x) = f(g(x))[/tex]
Rewrite as:
[tex]f(g(x)) = \frac{1 }{x - 6}[/tex]
Substitute g(x) for x - 6
[tex]f(g(x)) = \frac{1 }{g(x)}[/tex]
Replace g(x) with x
[tex]f(x) = \frac{1}{x}[/tex]
Hence, the function f(x) is: [tex]f(x) = \frac{1}{x}[/tex]
