Answer:
-3x^2-10x+6
Step-by-step explanation:
the first mistake would be writing the 4x^2 as positive when it's supposed to be negative. the 1 is also supposed to be positive. correct difference would be:
(x^2-10x+5)-(4x^2-1)
=(x^2-4x^2)-10x+5+1
=-3x^2-10x+6
Answer:
Mistake in step 2
Step-by-step explanation:
(x^2-10x+5)-(4x^2-1)
x^2-10x+5-4x^2+1
-3x^2-10x+6
-(3 x^2 + 10 x - 6)
There is a mistake in step 2 in the picture,
-(4x^2-1)

Explain what the algebraic solution of a system of two linear equations is and what that means in terms of the graphs of the equations of the system. Use AT LEAST 2 complete sentence in
your explanation. (3 points)
Answers
The goal of the method of substitution is to reduce a system of two linear equations in two variables to a single equation in one
variable.
The key step in using method of elimination is to obtain opposite coefficients for one of the variables so that adding the two equations eliminates this variable.
Solving systems of linear equations by graphing involves sketching the lines representing the equations to determine whether the lines intersect at a point, which is the solution of the system.

x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The meaning of end behavior is how the function ‘y’ (in this case) moves when x tends towards both ∞ and - ∞.
As x → ∞ y → ∞.
This is apparent from the upward movement of the graph of the function y=10x⁹ –4x
As x →- ∞ y → -∞
This inference is also drawn from the above graph i.e. as x values become more negative the graph of y also travels towards infinity i.e. southward on the LHS of the above graph.
Even though the graph of the function remains flat in between x = -4 to x = 4.
After these points, the graph moves towards infinity exponentially.
Hence, x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x

Find the measure of each angle indicated.

C) 23
E) 25°
B) 80°
D) 20°
Answers
Answer:
D) 20⁰
Step-by-step explanation:
EDF = 180-100=80⁰
EFD= 80⁰+80⁰=160⁰
180⁰-160⁰=20⁰
Answer:
I would say D, 20°
Step-by-step explanation:
angles on a straight line should be equal to 180°. so 180 -100 = 80° inside.
angles inside a triangle should also be 180. So, 80° + 80° =160°. to get the other angle subtract 160 from 180 to get 20°

Meg is a veterinarian. She found that 33% of the 21 dogs she saw this week were boxers.Steve is also a veterinarian. He found that 10,or 50% he saw this week were boxers.Does each person need to find the part, the whole, or the percent? Meg needs to find the?
Answers
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
The question is incomplete.
This is the complete question:
Meg is a veterinarian. In a given week, 50% of the 16 dogs she saw were Boxers. Steve is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part the whole, and the percent.
a. Does Meg need to find the part, the whole, or the percent.
b. Does Steve need to find the part, the whole, or the percent.
Solution to the problem
a. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
b. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
