Answer:
Step-by-step explanation
taco: góc FBC + góc FBA = 90° mà góc FBA + góc FAB = 90
⇒góc FAC = góc FBC mà góc FBC = góc EDC ⇒ góc FAC = góc EDF
xét Δ ABF và Δ DCE có
góc FAC = góc EDF
góc F = góc E = 90°
⇒ tam giác ABF đồng dạng với tam giác DCE
⇒ AB/DC = BF/EC ⇒ AB.EC = DC.BF mà AB = DC ⇒ EC=BF=4
Answer:
(x-6)(4) = 4x-24 (Answer is 4x-24)
Step-by-step explanation:
<u>ok here's the step </u>
<h2><u>
(x-6)(4) so you do this read it </u></h2><h2><u>
so the steps are =(x+−6)(4)</u></h2><h2><u>
=(x)(4)+(−6)(4) so then you will get 4x-24</u></h2><h2><u>
</u></h2>
Answer:
The general form of an exponential function is
.... (1)
Where, a is initial value and b is growth or decay factor.
If b>1, then it is an increasing function and if 0<b<1, then it is a decreasing function.
The given function is
.... (2)
From (1) and (2) it is clear that
The value of a is 6. It means the initial value or y-intercept of the function is 6.
The value of b is 0.4, which is less than 1. It means the function is a decreasing function.
Y=d-3. Y is equal to the cost of the sweaters before the price was raised. D represents the price of the sweaters after the price jump. The three is how much the sweater price was raised by. Say the new price of the sweaters are $29.99 each. You would plug in 29.99 for d. y=29.99-3. The new price of the sweaters would be $26.99 (this is just a sample problem)
