Answer:
a = 1,450,000
b = 290,000
Step-by-step explanation:
A: 1,740,000 = x*1.20
1,740,000/1.2 = x1.20/1.20
1,450,000 = x
B: 1,740,000 - 1,450,000 = 290,000

Which describes the process that could be used as the first step in solving this equation? 6x = 4 + 5(x + 8) A) Combine like terms by adding 4 + 5. B) Use distributive property to multiply 5(x + 8). C) Use division property of equality to divide both sides of the equation by 6. D) Use subtraction property of equality to subtract 6x from both sides of the equation.
Answer: B) Use distributive property to multiply 5(x + 8).
Step-by-step explanation:
trust me its right
The first step in solving this equation 6x = 4 + 5(x + 8) is,
⇒ Use distributive property to multiply 5(x + 8).
Option B is true.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 6x = 4 + 5(x + 8)
Now, We can solve the expression as;
⇒ 6x = 4 + 5(x + 8)
⇒ 6x = 4 + 5x + 40
⇒ 6x - 5x = 44
⇒ x = 44
Thus, The first step in solving this equation is,
⇒ Use distributive property to multiply 5(x + 8).

Graph the data in the table. Which kind of function best models the data? Write an equation to model the data.
A. quadratic; y = –2.5x2
B. linear; y = 2.5x
C. exponential; y = 2.5x
D. quadratic; y = 2.5x2
Answer:
D. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
A. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
x -2 -1 0 1 2
y 10 2.5 0 2.5 3.0
Ist difference,
= -2.5
= 2.5
= 7.5
2nd difference,
= 5
= 5
= 5
Since 2nd difference is common, given table represents a quadratic equation.
Let the equation is,
y = ax²+ bx + c
For a point (0, 0) passing through the quadratic equation,
0 = c
Therefore, quadratic equation is y = ax² + bx
Since ordered pair (-1, 2.5) passes through the graph of the function,
2.5 = a(-1)² + b(-1)
a - b = 2.5 ------(1)
For another point (1, 2.5)
2.5 = a(1)² + b(1)
a + b = 2.5 ------(2)
By adding equations (1) and (2),
2a = 5
a = 2.5
and from equation (2)→ y = 0
Therefore, equation of the quadratic function given in the table is y = 2.5x²
Option (1) is the answer.

What is the solution to this system of equations using the linear combination method?
Please help!!
Answer:
x= -3, y= 13
Step-by-step explanation:
The idea is that x and y in both equations are the same numbers and that the equations are like rules that need to be followed both in the same time.
We take the y from one equation and use it in the other equation because is the same y .
3x+y =4 , subtract 3x from both sides
y= -3x+4
2x+y =7 , substitute y with the y = -3x+4 from the first equation
2x -3x+4 = 7, subtract 4 from both sides
2x-3x = 7-4, combine like terms
-x = 3 so x = -3
We know that x= -3 so we can substitute it in y= -3x+4 to find y
y= -3x+4
y= -3 (-3) +4
y= 9+4 = 13
y= 13

w(x) = x2 + 1; Find w(x + 3)
Given the function w:
[tex] \displaystyle \large{w(x) = {x}^{2} + 1 }[/tex]
Since we want to find w(x+3), the input would be x+3.
Substitute x = x+3 in.
[tex] \displaystyle \large{w(x + 3) = {(x + 3)}^{2} + 1 }[/tex]
Alternate Solution
The answer above works if you want it in vertex form. For this alternate solution, I will convert the function in standard form.
As we know:
[tex] \displaystyle \large{ {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} }[/tex]
Therefore:
[tex] \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 2(x)(3) + {3}^{2} } \\ \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 6x+ 9}[/tex]
Now for function w:
[tex] \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 9+ 1 } \\ \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 10}[/tex]
Hence:
The answer is w(x+3) = (x+3)^2+1 for vertex formOR w(x+3) = x^2+6x+10Question 1 options:
You want to go out shopping to buy 2 dozen eggs at $10, 3 loaves of bread each at $5, and 5 bottles of drinks, each at $8. How much money do you need
Answer:
Step-by-step explanation:
24 eggs = 10 dollars
3 loafs of bread for 5 dollars each x 3 = amount together so 15
5x8=40 dollars for all drinks, so
10+15+40
Hey there! I'm happy to help!
First, we have our eggs, which cost $10
10
Then, we have our 3 loaves of bread. Each one costs $5. 5×3 is 15, so we will add this to our total.
10+15
And then we have our 5 drinks, each costing $8. 8×5 is 40, so we will add 40 to our total.
10+15+40=65
So, we need $65 dollars to go out shopping.

The area of triangle ABC is
square units.
Answer: Area = 17.5 unit²
Concept:
Here, we need to know how to calculate the area of a triangle.
Area (triangle) = b · h · (1/2)
b = base
h = height
Solve:
Given information (By counting grids on the graph)
b (AB) = 7
h (BC) = 5
Given expression
Area = b · h · (1/2)
Substitute values into the expression
Area = (7) · (5) · (1/2)
Simplify by multiplication
Area = (35) · (1/2)
Area = [tex]\boxed{17.5}[/tex]

find the complement of the B in universe U. U is the set of natural numbers less than or equal to 8. B is the set of even factors of 8.
Answer:
{1,3,5,6,7,8}
Step-by-step explanation:
U={1,2,3,4,5,6,7,8}
B={2,4}
B is even factors so you won't start with one
The complement of set B will be {1, 3, 5, 6, 7}
A set is an arrangement or collection of numbers. Given the universal sets:
Natural numbers are positive integers starting from 1. Hence the universal set will be:
U = {1, 2, 3, 4, 5, 6, 7, 8}
Factors of 8 are 1, 2, 4 and 8
Set of even factors of 8 will be 2, 4 and 8
B = {2, 4, 8}
Compliment of a set B are sets that are in the universal set but not in set B. Hence the complement of B will be {1, 3, 5, 6, 7}

The equation of a line in the point-slope form is show below. 4 – 9 = (x – 2) What is the slope of this line?
Answer:
undefined
Step-by-step explanation:
4 - 9 = x - 2
-5 = x - 2
-3 = x
this is a vertical line (parallel to the y-axis) at x = -3.
that means the slope of this line is "undefined". or some would call it "infinite".
as the slope is the ratio of y/x describing how many units y changes, when x changes a certain amount of units.
now the change of x for this line is constant 0.
so, we have a slope y/0, which is undefined.
What is Slope=2, y-intercept =5
y = 2x + 5
x= -3 , y= -11x= -2 , y= -9x= -1 , y= -7x= 0 , y= 5x= 1 , y= 7x= 2 , y= 9x= 3 , y= 13
1458 smallest whole number by which it should be multiplied so as to get a perfect square number.also find the square root of the square number obtained
9514 1404 393
Answer:
254Step-by-step explanation:
The prime factorization of 1458 is ...
1458 = 2·3^6
The exponent of 3 is even, but we need another factor of 2 to make the exponent of that factor even. You will get a perfect square by multiplying by 2.
√(2·1458) = √2916 = 54
Multiplying by 2 will give the square of 54.
