What is the solution to the system of equations? O (-6,-) O (-2, 6) O (6,2) O (-2,-6)​

Answer:

A. 190/5.

Step-by-step explanation:

Adele made 190 cookies, which is five times the amount of cupcakes she made. To find the amount of cupcakes she made, we must divide 190 by 5. By doing this we get the answer: 38 cupcakes.

Answer:

colinear pts (meaning gradient is same throughout)

Step-by-step explanation:

since grad is same,

(2-0)/(2-3) = (a-0)/(0-3)

-2 = a/-3

6 = a (multiply both sides by -3)

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The total number of cards the child has can be calculated using the steps below.

We can use the following steps:

- Prime factorization of each number:

2= 2

4=  2²

8 = 2³

12 = 2² x 3

- For each prime factor, choose the maximum exponent in any row, and multiply those together to get the least common multiple.

i.e

The maximum exponent of 2 is 3 and the exponent of 3 is 1.

- The least common multiple.

= 2³ x [tex]3^1[/tex]

= 24

- Add one to get the total number of cards.

Now,

The child's baseball cards.

= 24 + 1

= 25

Therefore,

The child has 25 baseball cards.

Q1

|a-b| = b-a when a<b

Q2

104159/33000

Step-by-step explanation:

Q1

If a<b then a-b will always be negative.  To get the absolute value, we can take -(a-b) = -a+b = b-a.

Q2

Let x = 3.12789789789...

We isolate the repeating decimal to start after the decimal, so we multiply by 100.

100x = 312.789789789...

We want to multiply by 10 for each digit that repeats (in this case 3), to get the repeating part to the left of the decimal.

100000x = 312789.789789

Subtracting the two...

x(100000-100) = 312789.789789 - 312.789789

99900x = 312477

x = 312477/99000 = 104159/33000

Step-by-step explanation:

Start with the series representation for eˣ.

eˣ = ∑ₙ₌₀°° xⁿ / n!

Substitute -x².

e^(-x²) = ∑ₙ₌₀°° (-x²)ⁿ / n!

e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ) / n!

Multiply by x².

x² e^(-x²) = x² ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ) / n!

x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ⁺²) / n!

Integrate both sides (use power rule).

∫ x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ⁺³) / ((2n + 3) n!)

Evaluate between x=0 and x=0.5.

∫ x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (0.5²ⁿ⁺³) / ((2n + 3) n!)

This is an alternating series, so use alternating series estimation.

(0.5²⁽ⁿ⁺¹⁾⁺³) / ((2(n+1) + 3) (n+1)!) ≤ 0.001

(0.5²ⁿ⁺⁵) / ((2n + 5) (n+1)!) ≤ 0.001

n ≥ 1

So the estimate of the integral is the sum of the first two terms (n=0 and n=1).

I = (-1)⁰ (0.5³) / ((3) 0!) + (-1)¹ (0.5²⁺³) / ((2 + 3) 1!)

I = (0.5³) / 3 − (0.5⁵) / 5

I = 1/24 − 1/160

I = 17/480

I = 0.0354

c. 32 ounces

Step-by-step explanation:

Given that:

The weight of the Spot = 12 ounces

The weight of Rascal = 9.5 ounces;  &

The weight of Socks = 10.2 ounces.

To find the litters' total weight, we will sum all the given number of the puppies.

i.e. Total weight of the litter = (12 + 9.5 + 10.2) ounces

Total weight of the litter = 31.7 ounces

Total weight of the litter [tex]\simeq[/tex] 32 ounces to the correct number of significant figures.

c=5/2k+ −45/2

Step-by-step explanation:

Answer:

K= 9 + 2/5C

Step-by-step explanation:

1. Remove the parentheses

C= 5/2 x (k-9)

2. Multiply both sides

C= 5/2k- 45/2

3. Move the terms

2C= 5k- 45

4. Divide both sides

-5k= -45- 2C

100 feet : 15 inches

3 1/3 feet : 1/2 inch

Answer:

[tex]3\frac{1}{3}[/tex] feet

Step-by-step explanation:

Inches : Feet = 15 : 100

Let 'x' be the feet required to find

15 : 100 :: 1/2 : x

Product of extremes  = product of means

          15 * x = 100 * (1/2)

          15 * x = 50
