Answer:
a = 2(vt -d)/t^2
Step-by-step explanation:
Add the term containing "a":
d + a(t^2/2) = vt
Subtract d:
a(t^2/2) = vt -d
Multiply by the inverse of the coefficient of "a":
a = 2(vt -d)/t^2
The answer is 2 because 2(3)= 6, and 7-6= 1. And 1 is half of the original, which is 2!
Answer:
B. y² – 5y = 750
C. 750 – y(y – 5) = 0
E. (y + 25)(y – 30) = 0
I'm assuming the 2 in the second option is supposed to be an exponent.
Step-by-step explanation:
Length = y
Width = y-5
Length × Width = Area
Area = <u>y(y-5)</u> = 750
<u>Distribute.</u>
y²-5y=750 (B is correct)
<u>If you factor the equation above</u>
(y + 25)(y – 30) = 0 (E is correct)
Area = y(y-5) = 750
<u>Subtract y(y-5) from both sides.</u>
750-y(y-5) = 0 (C is correct)
Answer:
the similarity statement helps you see that side RQ corresponds to UV, therefore 2x-4 : 5, and VW and QP are corresponding sides
Step-by-step explanation:
set up a proportion, then cross-multiply
2x-4/16 = 5/8
8(2x-4) = 16(5)
x = 7
B. Decreases
(Hopefully I’m right!)
