Answer:
8x^3+2x^2-3x+4
Step-by-step explanation:
8x³ +2x² -3x+4 is the standard form of the (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)
7x³ + 7x² – 4+x³ – 5x² – 3x + 8
In the given expression x is the variable
Plus and minus signs are the operators of the given expression.
Add the like terms in the given expression
8x³ +2x² -3x+4
Hence, 8x³ +2x² -3x+4 is the standard form of the (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.
Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
or, y= 15 x +70
which is in the form of,
y= mx +c (slope intercept form)
where,
m= slope
x= x- intercept
c= constant.

Answer:
X = 74°
Step-by-step explanation:
90 + 30 = 120 (S + T = 120 )
180 - 120 = 60 (triangles total - S and T's Total = U )
120 - 46 = 74 (The angle TUX is 120 so the answer is 74)

What is the volume of the box? 46.808 in cubed
What is the volume of the box if it is scaled down by a factor of 1/10?
Answer:
Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
Answer:
y = (1/2)x + 25 or y = 0.5x + 25

Each soda costs $4.50 at the baseball game. Which of the following represents the dependent variable?
Answer:
The price of the soda.
Step-by-step explanation:
The dependent variable is the variable defined to be dependent on another object, typically the independent variable. That means the variable that varies based off of another value is the dependent variable. In this situation, as the number of sodas bought increases, the total price increases. The price varies off of the number of sodas because the increase in sodas causes it to increase. Thus, the price is the dependent variable.
The dependent variable would be the total cost of the sodas.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Each soda costs $4.50 at the baseball game.
Here, The cost of the sodas is dependent on the number of sodas purchased, which is the independent variable.
Thus, The dependent variable would be the total cost of the sodas.

What we need to know: How many baseballs are in one case?
What we need to do: Divide 6 by 1/5 (or multiply by 5).

Dividing a fraction is the same thing as multiplying by its inverse.
6 * 5
Multiply 6 by 5 to get 30.
