Help please!! Triangle QRS is similar to triangle TUV. Write the equation, in slope-intercept form, of the side of triangle QRS
Vanyuwa [196]

Answer:

  y = x +9

Step-by-step explanation:

Side RS of triangle QRS is the one that is parallel to side UV. Being parallel, it has the same slope as UV. We observe that UV has a "rise" of 3 units (from 2 to 5) and a "run" of 3 units (from 1 to 4). Its slope is ...

  m = rise/run = 3/3 = 1

__

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

We observe that point S has coordinates (-8, 1), so we can write the equation of line RS in point-slope form as ...

  y -1 = 1(x -(-8))

Adding 1 to both sides and simplifying, we have the slope-intercept equation ...

  y = x +9

I promise I will mark as brainiest if a speed of a car increase its average speed in a journey of 200 miles by 5 mile/hour the j
jok3333 [9.3K]

Answer:

\large \boxed{\sf \ \ \ \dfrac{\sqrt{4025}-5}{2}=29.22144... \ \ \ }

Step-by-step explanation:

Hello

<u>Let's note the original speed of the car v</u>

it means that in 1 hour he is going v miles

so to go 200 miles it takes ( in hour)

\dfrac{200}{v}

If the speed of the car is v+5 than to go 200 miles it takes (in hour)

\dfrac{200}{v+5}

and this time is one hour less so we can write

\boxed{\sf \ \ \dfrac{200}{v+5}=\dfrac{200}{v}-1 \ \ }

We can multiply by v(v+5) both parts of the equation so

200v=200(v+5)-v(v+5)\\\\200v=200v+1000-v^2-5v\\\\v^2+5v-1000=0

\Delta=b^2-4ac=5^2+4*1000=4025\\\\ \text{There are potential solutions }\\\\\ \ \ \ \ x_1=\dfrac{-5-\sqrt{4025}}{2}\\\\\ \ \ \ \ x_2=\dfrac{-5+\sqrt{4025}}{2}

Only one is positive and this is is

x_1=\dfrac{\sqrt{4025}-5}{2}=29.22144...

So the original speed is 29.22144... mph

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Which inequality has an arrow pointing to the left when the solution set is graphed on a number line?
kupik [55]

Answer:

x \le 5

Step-by-step explanation:

Given

Options (a) to (d)

Required

Which represents an arrow pointing left

When an arrow points left on an inequality graph, the inequality is either of the following:

x < a or x \le a

From the given options (a) to (d), only x \le 5 fits the above description.

Other options illustrate an arrow pointing to the right

To further explain this;

Looking at (b), we have:

4 \le x

This is rewritten as:

x \ge 4 --- the same form as (c) and (d)
