I do not know if there is a photo for your question but here is a very easy way to tell if a triangle is a right triangle!

A right triangle will always have a 90 degree angle and two acute angles. A 90 degree angle is a angle like the corner of a book or table. An acute angle is anything smaller than a 90 degree angle.

What is the slope of a line that passes through (-4,-13) and (19,11)?

raketka [301]

We can find the slope from the two given points using the standard formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{11-(-13)}{19-(-4)}$
$m=\frac{24}{23}$

JulijaS [17]

Answer:

$y = -3+ rx$

Step-by-step explanation:

Given

$Base = -3C$

$Time = x$

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

$y = Base + Rate * Time$

$y = -3+ r* x$

$y = -3+ rx$

Divide 36 books into two groups so the ratio is 5 to 7. (Use the double number line strategy)

lutik1710 [3]

A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)

So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.

P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)
