Answer:y=-2x-1
Step-by-step explanation:
(1,-3) and a slope of -2
Use Formula
Y= mx +b to find b. By using the slope and point given .
M is slope
Y is -3
X Is 1
Y=mx+b
-3= -2(1)+b
-3= -2+b
-3+2=b
-1=b
Now create the equation by inputting the slope they gave you which is -2 and answer we solved for b which is -1 .
Y= -2x-1
-10/5 or -8/4
You can make up an equation with the solution of -2 by multiplying -2 by any number ( for example -2 x 5 ) and then divide the result by the random factor you chose ( which would be 5 in this case )
Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5
The slant height of the pyramid can be calculated using Pythagoras theorem. Therefore, the slant height is 6.7 mm
<h3>How to find slant height of a pyramid?</h3>
The slant height x, can be found using Pythagoras theorem,
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are other two legs.
Therefore,
x² = 4.5² + 5²
x² = 20.25 + 25
x² = 45.25
x = √45.25
x = 6.72681202354
x = 6.7 mm

Answer:
4x - 5y = 10
Step-by-step explanation:
Any line parallel to 4x - 5y = 35 will have the same equation EXCEPT that the constant will be different.
Starting with 4x - 5y = 35, replace x with the given x-coordinate -5 and the given y-coordinate -6, and finally the given 35 with the constant C:
4(-5) - 5(-6) = C, or
-20 + 30 = C. Thus, C = 10, and the equation of the new line is
4x - 5y = 10
