Answer:

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

Answer:

n= -9, t= -9

Step-by-step explanation:

1) -1/3(n+15)=-2

-1/3×n+-1/3×15=-2

-1/3×n -5= -2

-1/3 n-5+5= -2+5

-1/3×n=3

3/-1×-1/3×n=3/-1×3

n= -9

2) 46 = -6t -8

−6t−8=46

−6t−8+8=46+8

−6t=54

Divide both sides by -6

t=-9

Answer:

" The x-coordinato is negative, and the y coordinato is negativo. "

Step-by-step explanation:

Both are in the bottom left quadrant: -x -y

You started here:

And reflected across the ☝ line aka Y

Which means it would now be on the left

Step-by-step explanation:

When you multiply exponents of the same base (variable), add the exponents.

1. The exponents are 12 - 4 + 6 = 14 or c^14

When you divide exponents of the same base, subtract them.

2. 8 - 2 = 6 or c^6

When you raise a power to a power, you multiply the exponents.

3. 4 * 5 = 20 or c^20

When a number is raised to a negative exponent it can be re written like this x^-n = 1/x^n.

4. x^-2 * y / x^4 * y^-1; using the above information, rewrite everything to have positive exponents. If the negative exponent is in the denominator, then it becomes x^n/1

y * y / x^2 * x^4 ; then just add your exponents to simplify

y^2 / x^6

As we said before, a power raised to a power is exponent x exponent.

5. (a^2 * b) ^-1 / (a^-3 * b^2)^-1 ; as before a power raised to a power, multiply the powers.

a^-2 * b-1 / a^3 * b^-2 rewrite this as before, inverting negative exponents. a^3 / a^2 * b^1 * b^2 = a^3 / a^2 * b^3

Simolifynthe new expression to reduce the a variable by subtracting the bottom a^2 from the top a^3 and are left with

a / b^3

Work number 6 like 5, no negative exponents, so there won't be any inversions. Just multiply the outside power times every exponent, then do the division by subtracting exponents of like bases.

When figuring out the problems with constants, treat them like the variables. In number 7 the 5a^2 when raised to the 2nd power would be 5^2*(a^2)^2 = 25 a^4

Unit rate is 1.5

Step-by-step explanation:

4 pounds  = $6

Divide 6 by 4 = 1.5

Check: 4 * 1.5 = 6

Hence,

1 pound = $1.5

Answer:

15. 1.125 hours = 1 hour 7 minutes 30 seconds

17. 3840 cal

18. 60 g

Step-by-step explanation:

15.

8 miles is to 3 hours as 3 miles is to x hours

8/3 = 3/x

8x = 3 * 3

8x = 9

x = 1.125

Answer: 1.125 hours = 1 hour 7 minutes 30 seconds

17.

1/2 avocado is to 160 cal as 12 avocados are to x cal

(1/2)/160 = 12/x

(1/2)x = 12 * 160

x = 24 * 160

x = 3840

Answer: 3840 cal

18.

We need the same units. We convert 2 1/2 cups into tablespoons.

1 cup = 16 tablespoons

2 1/2 cups = 2 1/2 * 16 tablespoons = 2.5 * 16 tablespoons = 40 tablespoons

Now we start the proportion.

1.5 g to 1 Tbsp is as x is to 40 Tbsp

1.5/1 = x/40

x/40 = 1.5

x = 1.5 * 40

x = 60

Answer: 60 g

Answer:

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Step-by-step explanation:

Step(i):-

Let x and y are two numbers

Given that the sum of two numbers

 x + y = 15 ..(i)

Given that the difference of two numbers

x - y = 3 ..(ii)

adding (i) and (ii) , we get

x + y + x -y = 15 +3

  2 x = 18

    x =9

Step(ii):-

Substitute x = 9 in equation (i) , we get

x + y = 15

9 + y = 15

     y = 15 - 9

    y = 6

Final answer:-

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Answer:Add x to both sides of the equation.y=3+2x

Step-by-step explanation:

could y be 9 im lost

Answer:

Geometric

Step-by-step explanation:

A geometric setting does not have a set number of trials, and the variable in question is the number of trials it takes to get the first success.

The upgrades are independent, and the probability of the customer upgrading is the same each time.

The type of variable NNN is Geometric

Suppose a number is 'a'

Suppose another number is 'b'

We want to know how much percent of 'b' is 'a'.

We are given that Alma wrote a phone app. She has noticed that 3%, percent of the users who download her app upgrade it the same day.

Let N be the number of customers who download Alma's app until one upgrades it on the same day.

( 5 + s ) 4 = 20 + 4 s

Step-by-step explanation:

Distribution property

Let a, b and c are numbers then distribution property is defined by

a( b + c) = a b + a c

(a+ b) c = a c + b c

Given that

( 5 + s ) 4 = 5× 4 + s× 4

               = 20 + 4 s

Final answer:-

( 5 + s ) 4 = 20 + 4 s

Answer:

This is the subtraction method

Y -3X = -10

(-Y -2x = -5)  -Y + 2X = 5

Y -3X = -10

-Y + 2X = 5

      -X = -5

X = 5  Now fill in the 5 for X and Y =  5

Answer:

x = 5, y = 5

or

(5, 5)

Step-by-step explanation:

they both equal y so they also equal each other.

3x - 10 = 2x - 5

3x - 2x = -5 + 10

x = 5

substitute x for 5

y = 3x - 10

y = 15 - 10

y = 5

edit, whops forgot to check

just plug the variables in with their values and see if it makes sense:

y = 2x - 5

5 = 2*5 - 5

5 = 10 - 5

5 = 5

since 5 does equal 5, the solution is correct.
