Answer:

y = 2x - 3

Step-by-step explanation:

To solve for y, use the point slope formula: y2 - y1 / x2 - x1

Given the points (3, 3) and (4, 5) 5 - 3/4 - 3

2/1

m = 2

Use the slope m = 2 and one of the given points such as

(3,3) to substitute for x1 and y1 in the point-slope form

So, y - y1 = m x (x - x1)

y - (3) = 2 x (x-3)

Solve for to get the equation. y = 2x - 3

an architect wants to build three similar triangles such that the ratio of the middle triangle. The smallest one has side length

vampirchik [111]

Answer: 15

<u>Step-by-step explanation:</u>

small: 5 12 13

middle: __ 36 39

large: 45 108 117

Notice that to get from the small to the large, multiplied by 9

5(9) = 45 12(9) = 108 13(9) = 117

That is because the sides are proportional $\dfrac{5}{45}=\dfrac{12}{108}=\dfrac{13}{117}\rightarrow\dfrac{1}{9}$

To get from small to middle, multiply by 3

5(3) = 15 12(3) = 36 13(3) = 39

To solve it using proportions:

$\dfrac{5}{x}=\dfrac{12}{36}\\\\\\\text{Cross Multiply and solve for x:}\\5(36)=12x\\\\\dfrac{5(36)}{12}=x\\\\5(3)=x\\\\\large\boxed{15}=x$

Answer:

4th one

Step-by-step explanation:

a^-2 goes down and become a^2 and

${a}^{2} \times {a}^{2} = {a}^{4}$

b^-1 goes up and become b

${b}^{2} \times {b}^{1} = {b}^{3}$
