Answer:
Step-by-step explanation:
Let the scale factor is k.
<u>Then the transformation is:</u>
<u>We have:</u>
<u>The scale factor is k = 12, find the value of a:</u>
- 3a² = 12
- a² = 4
- a = √4
- a = ± 2
Its 17, because i made a graph
Answer:
4x+3
How: -2x - (-6x) = 4
3 cannot be added there you go
5.4/7=27/h
We simplify the equation to the form, which is simple to understand
<span>5.4/7=27/h
We move all terms containing h to the left and all other terms to the right.
<span>-1h=-0.77142857142857
We simplify left and right side of the equation.
<span><span>-1h=-0.77142857142857
</span>We divide both sides of the equation by -01 to get h.
<span>h=0.77142857142857</span></span></span></span>
Answer:Number of minutes of second Song = 5 1/4 minutes
Number of minutes of third Song =3 1/2 minutes
Step-by-step explanation:
Number of minutes of First Song = 3 1/2 minutes
Number of minutes of second Song = one 1/2 times as long as her first
= 1 1/2 X 3 1/2 minutes
3/2 X 7/2
21/4 = 5 1/4 minutes
Number of minutes of third Song = 2/3 times as long as her second song
2/ 3 x 5 1/4
= 2/3 x 21/4 =42/12
Dividing the numerator and denominator by 3 to reduce the fraction
42/ 12 / 3/3 = 14/4
14/4 = 3 2/4 = 3 1/2 minutes
