Answer 1

Step-by-step explanation:

-4.5x -2y = -12.5 -------(1)

3.25x -y = -0.75 --------(2)

From (2) we can make y the subject of the relation

y = 0.75+3.25x -------(3)

Input 0.75+3.25x into y in (1)

-4.5x -2(0.75+3.25x) = -12.5

-4.5x -1.5- 6.5x = -12.5

-4.5x -6.5x -1.5 = -12.5

-11x = -12.5 +1.5

-11x = -11

x = 11/11

x = 1

If x = 1,substitute 1 into x in (3)

y = 0.75+3.25x

y = 0.75 +3.25(1)

y = 0.75 +3.25

y = 4

x = 1,y = 4

M (18, 24) is the midpoint of segment JL with J (- 4, - 2). What are the coordinates for L?

Answers

Answer:

mid point (x,y) = M (18, 24)

let J (- 4, - 2) be ( x1, y1)

     L(a,b) be (x2,y2)

using midpoint formula

(x,y) = [(x1+x2)/2, (y1 + y2)/2]

or, (18, 24) = [(-4+a)/2, (-2+b)/2]

comparing corresponding element we get

18 = (-4+a)/2                 24 =(-2+b)/2

or 36 = -4+ a            or 48 = -2 +b

or a = 40                  or b= 50

L(40,50)

Answers

Answer:

Step-by-step explanation:

Begin at the end. By this I mean to start at the end of that expression and work your way backwards to the beginning. "The difference of t and 8" looks like this: t - 8. "2/3 of" means we are multiplying (the word "of" means to multiply): 2/3(t - 8) is your algebraic translation of that expression.

The required mathematical expression of a statement is 2 / 3 (t - 8 ).

Given that,
To transform the statement into the mathematical form,
2/3 of the difference between a number t and 8

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
given statement,
2/3 of the difference between a number t and 8
implies,
The difference between t and 8 is,
= t - 8
Now the difference is 2/3, now the statement become,
= 2 / 3 (t - 8 )
above equation is the required mathematical expression.

Thus, the required mathematical expression of a statement is 2 / 3 (t - 8 ).

In 2008, Scott Dixon won the Indianapolis 500, completing 500 laps in approximately 3.5 hours. Approximately how long did it take for him to complete 1 lap?

Answers

Answer:

0.007 hour or 25.2 seconds

Step-by-step explanation:

From the question, we are told that for Scott Dixon,he completed

500 laps in approximately = 3.5 hours. 1 lap approximately =

Cross Multiply

= 1 lap × 3.5 hours = 500 laps × a hours

a hours = 1 lap × 3.5 hours/500 laps

a hours = 0.007hours

We can convert 0.007 hours to seconds

60 seconds = 1 minute

60 minutes = 1 hour

1 hour = 60 × 60

= 3600 seconds

1 hour = 3600 seconds

0.007 hour =

0.007 hour × 3600 seconds

= 25.2 seconds

Therefore, it took Dixon approximately 0.007 hour or 25.2 seconds did it take for him to complete 1 lap

Michael and Ming-Wei are selling fruit for a school fundraiser. Customers can buy small boxes of
oranges and large boxes of oranges. Michael sold 3 small boxes and 14 large boxes for a total of $203.
Ming-Wei sold 11 small boxes and 11 large boxes for a total of $220. Find the cost of each size box.

Answers

L = large boxes S=small boxes
3s + 14l = 203
11s + 11l =220
You can eliminate a variable, I'm going to eliminate s but from the 2 equation since it's easier to do the math. I'm going to multiply the equation by -3. I'm going to multiply the first one by a positive 11.
-33s-33L=-660
33s + 154L= 2233
121L=1573
1573÷121 =13
So one large box equals 13, now find the price of a small by plugging it into an equation.
3s + 14 (13)=203
3s+ 182 =203
203-182=21÷3=7
Now a small equals 7, check if both are correct by putting it into another equation.
11 (7)+11 (13)=220
77+143 =220
220=220
A small equals $7, while a large equals $13.

So, what is the pattern? For positive integers a and b: (x^a)^b

Answers

Answer: (x^b)^a

Step-by-step explanation:

the inverse of a monomial with an exponent raised to another power will give the same product if you flip the exponents.

Here we have a general rule for exponents.

We will find that:

[tex](x^a)^b = x^{a*b}[/tex]

To get this, we can first check it with some values for the exponents.

a = 2

b = 3

[tex](x^2)^3 = (x^2)*(x^2)*(x^2) = (x*x)*(x*x)*(x*x) = x^6 = x^{2*3}[/tex]

Similarly, we can prove it for two general values of a and b:

[tex](x^a)^b = (x^a)*(x^a)*...*(x^a)\\b\ times[/tex]

Now each one of these parentheses has a multiplying by itself a times.

So when we write all the x's, we will see that there are a total of b*a x's

Thus we will have:

[tex](x^a)^b = (x^a)*(x^a)*...*(x^a) = x^{a*b}[/tex]

Which graph represents the solution to the inequality?1/3(9x+27)>x+33

Answers

Answer:

its c

Step-by-step explanation:

Graph D represents the inequality of the given Equation.

What is inequality?

An inequality shows whether one value is less than, greater than, or simply not equal to another value by comparing them.

When two quantities are equal, we use the symbol "=," and when they are not equal, we use the symbol "≠". The first value can either be greater than (>) or less than (<).

Given equation 1/3(9x+27) > x+33

simplify the Equation

multiply both sides by 3 we get,

[1/3(9x+27)] 3 > (x+33)3

9x + 27 > 3x + 99

9x > 3x + 99 -27

9x - 3x > 72

6x > 72

x > 12

the Equation of inequality is x > 12

the line will be more than 12 and in which 12 is not included,

option D follows the required conditions, the empty circle in 12 shows 12 is not included and the line moves towards the positive side.

Hence option D is the correct representation of the given inequality.

Answer:

Step-by-step explanation:

To evaluate f(5) substitute x = 5 into f(x), that is

f(5) = (5 - 2)² = 3² = 9

Answer:

f(5) = 9

Step-by-step explanation:

f(x) = ( x - 2)²

To find f(5) substitute the value of x that's 5 into f(x). That's for every x in f (x) replace it with 5

That's

f(5) = ( 5 - 2)²

= 3²

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be solved as below:-

5x = 3x

Multiply both sides of the expression by (1/x ).

( 1/x ) 5x = ( 1/x )3x

5 = 3

Divide both sides by x.

5x = 3x

5x /  x = 3x / x

5 = 3

Therefore, multiply/divide both sides by the same variable expression. The correct option is D.
