The answer is 70. When you multiply a negative and a positive you get a negative. For example, -5 x 7 = -35. Now when you have to multiply that by -2, negative times a negative is a positive because they cancel each other out. -2 x -35 =70

Answer:

hey there,

hey there,in this question

-7 is multiply by 5 then multiply by-2

use estimation to check whether 96.26 is a reasonable solution fot the equation m-62.74=159

Answers

Answer:

See below

Step-by-step explanation:

I hope you wrote down the right equation using a minus sign instead of a plus.

Rounding 96.26 off to just 96  and then rounding 62.74 off to 62, you can subtract the two in your head real quick.

96 - 62 = 34

So using this estimation you can see that the answer of 159 is no where near correct.

Find the exterior angle

Answers

Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

For any of you coding experts. I'm just beginning to take coding seriously and I want to know which coding language is the easiest for beginners. Any tips?​

Answers

Answer:

binary codenis the easiest bro it's just 1 and 0 right?

I believe HTML & MySQL are the easiest coding languages for beginners. If you are a starter you might prefer to take HTML which is comparatively really easy & understandable as well. HTML allows you to create webpages in no time with simple coding & there's no use of binary digits. Moving onto MySQL..this is also easy but it's advanced when compared to HTML. But, the work is more neat & good if you program it through SQL. After mastering both of them you can go for Python / Java, which are hard but it should be ok if you studied the first 2 languages. There's Xojo as well, lesser known but still good.

What is the equation of the line that passes through the point (-6, -5) and has a slope of -3/2?

Answers

Answer:

y=3/2x+3/2

Step-by-step explanation:

point at (-6,-5)

slope = m = 3/2

y = mx+b

(-6)=(3/2)(-5)+b >>> substituting x & y to solve for b

-6 = (-15/2)+b >>> simplify previous equation

-6 + (15/2) = b >>> isolate and solve for m

3/2 = b

therefore, the equation of the line passing through the point (-6,-5) with a slope of 3/2 is y=(3/2)x+(3/2)
