Answer:

Step-by-step explanation:

The slope = 4/2 = 2

and one point on the graph ( point B) is (5, 6) so point-slope equation is

y - 6 = 2(x - 5)

You can find the two coordinate points on graph as A(3,2) and (5 , 6)

Slope = (y2 - y1)/(x2 - x1)

Slope = (6 - 2)/(5-3) = 4/2 = 2

Point slope form formula:

y - y1 = m(x - x1)

Equation

y - 6 = 2(x - 5)

y - 2 = 2(x - 3)

Answer

(D) y−6=2(x−5)

Hope that helps

Given the function f(x) = 4(2)x, section a is from x = 1 to x = 2 and section b is from x = 3 to x = 4. part

Aliun [14]

A. Average rate of change for x=1 to 2: 4(2²)-4(2)=16-8=8; from x=3 to 4: 4(2⁴)-4(2³)=64-32=32.
b. Section b is 32/8=4 times greater. As the exponent of 2 increases, the gaps between consecutive powers of 2 gets wider and therefore the rate of change is greater.

Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)

castortr0y [4]

Answer:

The answer to your question is x = 21

Step-by-step explanation:

Equation

$\frac{2}{7} x = 6$

- Multiply both sides by 7

$\frac{(2)(7)x}{7} = 6(7)$

- Simplify

2x = 42

- Divide both sides by 2

$\frac{2x}{2} = \frac{42}{2}$

- Simplify

x = 21

Someone please help or i’ll be failing geometry this year

Step-by-step explanation:

I don't know what constructions you were taught.

a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.

by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).

and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.

I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.

we would get the triangles ABC, AMN and AXY.

the points B and C would be then halfway on AM and AN.

and M and N would then a bit before X and Y on AX and AY.

the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.

let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.

now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.

and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.

and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).
