Answer:
10x^2+7x+1
Step-by-step explanation:
Let's simplify this step-by-step.
3x^2+5x−9+7x^2+2x+10
=3x^2+5x+−9+7^x2+2x+10
After, combine like terms. (Simplify the expression)
Here is a step-by-step row.
= 3x^2+5x+-9+7x^2+2x+10
= (3x^2+7x^2)+(5x+2x)+(-9+10)
= 10x^2+7x+1
That is the most simplified form, I hope this helped!

Four friends bought an extra-large $12 popcorn. Each person bought their own drink. The total cost of the food can be represented by the expression 4x + $12.
Answer:
True
Step-by-step explanation:
This equation correctly represents the total cost of the food that the friends ended up paying for the popcorn and sodas. In this expression, the cost of each individual soda is represented by the variable x which is multiplied by 4 since each one of the four friend's purchased their own soda. After making this multiplication process that product is added to the initial $12 that they all spent together on the popcorn.
Each friend paid $4 for popcorn.
The total cost of the food can be represented by the expression 4x + $12.
Given
Four friends bought an extra-large $12 popcorn.
Each person bought their own drink.
Let x be the number of friends.
The total cost of food= Total number of friends + cost of popcorn.
The total cost of the food can be represented by the expression 4x + $12.
Therefore;
The amount paid by each friend is;
[tex]\rm 4x=12\\\\x=\dfrac{12}{3}\\\\x=4[/tex]
Hence, each friend paid $4 for popcorn.

When a system of linear equations is graphed, how is the graph of each equation related to the solutions of that equation?
Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Consider the polynomial function h(x) = -7x6 + 3x4 – 5x2.
What is the end behavior of the graph of h ?
Answer: As x -> ♾, h(x) -> -♾, and as x -> -♾,h(x) -> -♾
Step-by-step explanation:
The end behavior is x ----> ∞ then h(x) ----> -∞, and when x ----> -∞ then h(x) -----> -∞.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
h(x) = -7[tex]x^6[/tex] + 3 [tex]x^4[/tex]– 5x².
If we plot the Equation on the Graph we can see a parabolic Curve.
This Curve tells as x tends to ∞ the value of h(x) tends to -∞.
and, when x tends to -∞ the value of h(x) tends to -∞.
Hence, the end behavior is x ----> ∞ then h(x) ----> -∞.
and, when x ----> -∞ then h(x) -----> -∞.

What is the gravitational PE of the same 61.2 kg person standing on the 6th floor (Each story is 2.5 m high)?
Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Step-by-step explanation:
2w + 6 = -6
-6 -6
2w = -12
÷2 ÷2
w = -6

If there are 360 g of radioactive material with a half life (decreased by half or 50% )of 1 hour, how much of the radioactive material will be left after 4 hours ?
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after n hours, an initial amount A of this substance decays according to
A / 2ⁿ
