Answer:
Step-by-step explanation:
move x to the right making the equation 5y=-9x-1 then divide both sides by 5 to get y= -9/5x-1/5. the slope of a perpendicular line is the opposite reciprocal of the slope from the og eq. so the slope of the new line is 5/9x and the y-intercept stays the same so the equation should be y=5/9x-1/5
Answer:
B. 1.55 x 106
Step-by-step explanation:
This is an example of the distributive property. In order to turn it back to the regular form, you need to do this:
3.40
-
1.85
--------
1.55
Don't forget to put the 106!
3.40
-
1.85
--------
1.55 x 106
You can do it in both forms and get the same answer. It depends on what the question asks for or whichever form you like best/you think is the easiest.
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
Answer:
19375
Step-by-step explanation:
625*31=19375
Answer:
Multiplying by 1 does not change the ratio
Step-by-step explanation:
Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
