Find the length of the
missing side of the triangle
to the nearest tenth.

Answer:

3 or 3/1

Step-by-step explanation

the equation for finding the slope when given two coordinate pairs is (y₂ - y₁)/(x₂ - x₁), aka change in y over change in x.

pick one of your coordinate pairs to be y₂ and x₂. it doesn't matter which coordinate pair you choose. the remaining coordinate pair will be your y₁ and x₁.

for this example, i'll use the coordinate pair (7, 2) as my y₂ and x₂ and (1, 4) as my y₁ and x₁.

first, substitute the x-value and y-value from the first coordinate pair.

(y₂ - y₁)/(x₂ - x₁) ⇒ (7 - y₁)/(2 - x₂)

then substitute the y-value and x-value from the remaining coordinate pair.

(7 - y₁)/(2 - x₂) ⇒ (7 - 4)/(2 - 1)

subtract 7 - 4.

(7 - 4)/(2 - 1) ⇒ (3)/(2 - 1)

subtract 2 - 1.

(3)/(2 - 1) ⇒ (3)/(1) or 3/1

simplify.

3/1 ⇒ 3

Answer:

40 but see below.

Step-by-step explanation:

You have to assume that the figure is a parallelogram. That is never a safe assumption, but you have to make it because there is nothing else you can do.

That being the case, to get the perimeter, you just add the sides. If say well y could be just about any value with some limitations, you would be correct.

Per = 12 + 12 + 8 + 8 = 40

Answer:

yes,  point (4, 25) satisfies the equation y = 7x + –3

Step-by-step explanation:

to see if the point satisfies the equation, we need to plug in the x coordinate to get y

if y is equal to the y-coordinate, then the point satisfies the equation

if y does not equal the y-coordinate, then the point does not satisfy the equation:

y = 7(4) + - 3

y = 28 + -3

y = 25

does 25 = 25? Yes! so the point satisfied the equation

Answer:

yes

Step-by-step explanation:

7(x)- 3 = y

7(4) - 3 = (y)

28 - 3 = 25

Answer:

Pythagoras's theorem

Step-by-step explanation:

In the given drawing, there are three right triangles (two smaller triangles formed inside one right triangle), which are;

1) The smallest right triangle with side lengths 'b', 'f', and 'd'

2) The intermediate right triangle with side lengths 'f', 'a' and 'c - d'

3) The right triangle ΔABC containing the other two with side lengths, 'a', 'b', 'c'

By trigonometric ratio we have;

1/cos(B) = a/(c - d) = c/a

By cross multiplication, we get

a² = c² - c·d

Similarly, we have;

The vertex angle for the small right triangle at C = ∠B

1/sin(B) = b/d = c/b

∴ b² = c·d

Therefore, adding the values of 'a²', and 'b²' together, we get;

a² + b² = c² - c·d + c·d = c²

Therefore;

a² + b² = c² which is Pythagoras's theorem.

Answer:

169/4

Step-by-step explanation:

Take the coefficient of the x term.  Here it's -13.  Now halve that, obtaining -13/2.  Finally, square this result.  We get 169/4.  This is the desired number.

x^2 - 13x + 169/4 - 169/4 + 14 = 0

Answer:

6n-14

Step-by-step explanation:

First, put 6 times a number down, which is 6n, then minus 14, so it would be 6n-14.

The numerical form of statement 4 is less than 6 times a number, and n is

6n - 4.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

The given statement is 4 less than 6 times a number, n.

Therefore, The statement can be numerically expressed as,

6×n - 4.

= 6n - 4.

If 6n - 4 is an expression then 6n - 4 = 0  is an equation.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Answer: 25 chocolate frogs eaten by Luna

Step-by-step explanation:

let the amount of chocolate frogs eaten by Luna = x

and the amount of chocolate frogs eaten by Harry = 6+ x

Such that total a,mount of chocolate frogs eaten by both of them

= x +( 6+x) = 56

Step 2- Solving

x+6+x=56

6 + 2x= 56

2x= 56-6

2x= 50

x= 50/2

x= 25

x= 25 chocolate frogs eaten by Luna

6 +x= 6+ 25= 31 chocolate frogs eaten by Harry.
