Robert and Dora need to write 4,300,000,000 using scientific notation. Robert claims that 4,300,000,000 = 4.3 x 108 and Dora claims that 4,300,000,000 = 4.3 x 109. Which of the following best describes whose number is correct and the reason it is correct?
Answer:
Robert is correct
Step-by-step explanation:
we know in scientific notation a positive number goes to the right and if we do 4.3 and we go back the spaces it would be nine spaces so it would be 4.3 X 109
Solve 6y + 2x = 14 for x.
Answer:
x = 7 - 3y
Step-by-step explanation:
6y + 2x = 14 (divide all by two)
3y + x = 7 (move 3y to the right to isolate x)
x = 7 - 3y
Answer:
7-3y=x
Step-by-step explanation:
6y+2x=14
2x=14-6y >>> isolate x variable
x=7-3y >>> simplify because everything is divisible by 2

Step-by-step explanation:
Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they have sold a total of 45 items and earned $195. If hot dogs cost $4 and hamburgers cost $5, how many did they sell of each?
What would be a system of equations for the scenario above?
Answer:
15 hamburgers were sold and 30 hotdogs were sold.
The systems of equations are x + y = 45 and 4x + 5y = 195.
Step-by-step explanation:
Let's make two equations.
x + y = 45
This represents the total of hotdogs and hamburgers sold
4x + 5y = 195
This represents the amount of money made for each food.
These are systems of equations, when you use 2 equations to solve a problem. I will use the strategy, Elimination for the following systems of equations. Anyways the goal is to multiply a number to x + y = 45 to cancel out one of the variables in 4x + 5y = 195. In other words, when we add these equations, the sum of the xs or ys will equal 0.
Let's multiply -5 to both x and y.
Now we have -5x -5y = -225 + 4x + 5y= 195
We will end up with -x = -30. This means that x = 30.
Now that we know x = 30, we can plug in 30 as x in one of the equations. I will plug in 30 into x + y = 45. 30 + y = 45.
Solve for y in 30 + y = 45, so y=15.
This means 15 hamburgers were sold and 30 hotdogs were sold.
Find the slope given the following two points: (16,3) and (14, -19)
Answer:
the slope m=11
Step-by-step explanation:
(To find the slope use the equation m=[tex]\frac{y2-y1}{x2-x1}[/tex])
(16,3), where 16=x1 and 3=y1
(14,-19), where 14=x2 and -19=y2
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
=[tex]\frac{-19-3}{14-16}[/tex]
=[tex]\frac{-22}{-2}[/tex]
(simplify)

Horses A veterinarian measures a horse to be 7.5
ft tall at the shoulder to the nearest half foot. What
are the minimum and maximum possible heights of
the horse?
Answer:
Minimum height is 7.25ft and maximum height is 7.75ft
Step-by-step explanation:
You measured to the nearest half foot, so the greatest possible error is 0.25 foot.
Minimum height= measured value-possible error= 7.5-0.25= 7.25ft
Maximum height= measured value+possible error= 7.5+0.25= 7.75ft

If x is not a whole number, then x ≠ 5 is inverse of the statement if x is a whole number, then x = 5
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given statement is "If x is a whole number, then x = 5". To find its inverse, we need to switch the hypothesis and the conclusion, and negate both parts of the statement.
The hypothesis is "x is a whole number", and its negation is "x is not a whole number".
The conclusion is "x = 5", and its negation is "x ≠ 5".
So, the inverse of the given statement is:
"If x is not a whole number, then x ≠ 5."
Therefore, if x is not a whole number, then x ≠ 5 is correct answer.

The equation for a parabola has the form y = ax2 + bx + c, where a, b, and c are constants and a ≠ 0. Find an equation for the parabola that passes through the points (−1, −11), (1, −5), and (2, −8).
Putting (-1, -11) in given equation, we get :
-11 = a + -b + c ....1)
Similarly putting (1, −5) and (2, −8) we get :
-5 = a + b + c ....2)
-8 = 4a + 2b + c ....3)Adding equation of 1) and 2) we get :
2( a + c ) = -6
a + c = -3
Solving equation 1 , 2 and 3 ,we get :
a = -2 , b = 3 , c = -6
Therefore, equation of parabola is :
y = -2x² + 3x -6
Hence, this is the required solution.
