First you had to multiply with negatives seven and negative five. You can also multiply by the numbers.

-7*-5=-35

Final answer: \boxed{=-35}

35/5=7

7*5=35

5*7=35

35/7=5

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!

3w + 2 = 7w Please help
mash [69]
3w +2 =7w
-3w       -3w
2=4w
Divide each side by 4
1/2=w

Check your answer:
3 (1/2) + 2 = 7 (1/2)
(3/2) + (4/2) = (7/2)
(7/2) = (7/2)

Hope this helps.

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3).
poizon [28]

The first thing I'll do is solve "5y = 2x + 20" for "<span>y=</span>", so that I can find my reference slope:

y = (2/5)x + 4;

So the reference slope from the reference line is <span>m = 2/5;</span>.

Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line. 

Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope <span>m = 2/5</span>. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);

Finally, y = (2/5)x + 17/5;
