Step-by-step explanation:

Calculate the distance between (x, y) and the 2 given points and equate them.

Using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = P(- 3, 4)

d = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]

Repeat with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = Q(2, - 1)

d = [tex]\sqrt{(2-x)^2+(- 1- y)^2}[/tex]

Equating both distances

[tex]\sqrt{(2-x)^2+(-1-y)^2}[/tex] = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]

Square both sides

(2 - x)² + (- 1- y)² = (- 3 - x)² + (4 - y)² ← expand and simplify both sides

4 - 4x + x² + 1 + 2y + y² = 9 + 6x + x² + 16 - 8y + y²

subtract x² + y² from both sides

5 - 4x + 2y = 25 + 6x - 8y ( add 8y to both sides )

5 - 4x + 10y = 25 + 6x ( subtract 5 from both sides )

- 4x + 10y = 20 + 6x ( add 4x to both sides )

10y = 10x + 20 ( divide all terms by 10 )

y = x + 2 ← as required

The equation representing the change will be y = 30 - 1.95C. the correct option is C.

Expression in maths is defined as the collection of 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.

Given that Jon’s teacher wants to buy giant cookies for the entire class. If cookies cost $1.95 each.

The equation can be written as:-

y = 30 - 1.95C

Here, y is the change amount and C is the number of cookies.

X+2x+5x = 56. Divide 56 by 8 to get 7 = x. First=7. Second=14, third=35

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

first multiply them out: 5x+20=2x+11

then subtract both sides by 2x: 3x+20=11

subtract both sides by 20: 3x=-9

divide both sides by 3: x=-3

Answer:

x = -3

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

5(x + 4) = -2(-4 - x) + 3

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

Here we see that 5 does indeed equal 5. ∴ x = -3 is a solution of the equation.

And we have our final answer!

Answer:

Lauren's percent error = 13.95% Approx

Step-by-step explanation:

Given:

Number of photos predict = 129

Number of photos actual = 111

Find:

Lauren's percent error

Computation:

Lauren's percent error = [(Number of photos predict - Number of photos actual)/(Number of photos predict)]100

Lauren's percent error = [(129 - 111)/129]100

Lauren's percent error = [(129 - 111)/129]100

Lauren's percent error = [(18)/129]100

Lauren's percent error = 13.95% Approx

Answer:

a) The next two terms are: 13, 16

b) nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]

Step-by-step explanation:

a) Find the next two terms of sequence: -2,1,4,7 and 10

The common difference d: a₂-a₁ = 1-(-2)= 3

a₃-a₂= 4-1 = 3

a₄-a₃=7-4=3

So, common difference is : 3

Next two terms are: 10+3 = 13

13+3= 16

The next two terms are: 13, 16

b) Find nth term of the sequence

The nth term can be found using formula:

[tex]a_n=a_1+(n-1)d[/tex]

where a₁=First term and d=Common Difference

In the sequence given we have a₁=-2 and d=3

So, the nth term will be:

[tex]a_n=a_1+(n-1)d\\a_n=-2+(n-1)3\\a_n=-2+3n-3\\a_n=3n-5[/tex]

So, nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]

Step-by-step explanation:

If you look at the two angles, one is 7x and the other is 11x, they appear to be next to each other and make a right angle, if you look at the bottom corner of them there is a square which means it is a right angle. this means that if you put 7x with 11x it would = 90

Answer:

x = 2

Step-by-step explanation:

Solve for x:

8 x + 4 (x - 1) = 15 x - 10

Hint: | Distribute 4 over x - 1.

4 (x - 1) = 4 x - 4:

4 x - 4 + 8 x = 15 x - 10

Hint: | Group like terms in 8 x + 4 x - 4.

Grouping like terms, 8 x + 4 x - 4 = (8 x + 4 x) - 4:

(8 x + 4 x) - 4 = 15 x - 10

Hint: | Add like terms in 8 x + 4 x.

8 x + 4 x = 12 x:

12 x - 4 = 15 x - 10

Hint: | Move terms with x to the left hand side.

Subtract 15 x from both sides:

(12 x - 15 x) - 4 = (15 x - 15 x) - 10

Hint: | Combine like terms in 12 x - 15 x.

12 x - 15 x = -3 x:

-3 x - 4 = (15 x - 15 x) - 10

Hint: | Look for the difference of two identical terms.

15 x - 15 x = 0:

-3 x - 4 = -10

Hint: | Isolate terms with x to the left hand side.

Add 4 to both sides:

(4 - 4) - 3 x = 4 - 10

Hint: | Look for the difference of two identical terms.

4 - 4 = 0:

-3 x = 4 - 10

Hint: | Evaluate 4 - 10.

4 - 10 = -6:

-3 x = -6

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 x = -6 by -3:

(-3 x)/(-3) = (-6)/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

x = (-6)/(-3)

Hint: | Reduce (-6)/(-3) to lowest terms. Start by finding the GCD of -6 and -3.

The gcd of -6 and -3 is -3, so (-6)/(-3) = (-3×2)/(-3×1) = (-3)/(-3)×2 = 2:

Answer:

∠ C = 55°

Step-by-step explanation:

∠ W and ∠ A are adjacent angles and are supplementary, then

∠ A = 180° - ∠ W = 180° - 134° = 46°

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for ∠ C

∠ C = 180° - (46 + 79)° = 180° - 125° = 55°
