.2 (simplified from 0.20)

2/10 (simplified from 20/100)

Well, you know that 20% is out of 100.
So, take a fraction that is equivalent to 20% of 100. ( 2/10 works fine) or, 1/5
Then, take 20% and luckily, 20% is a benchmark so .2 (out of 10) works fine.

If you wash your car every 15 days & I wash mine every 20 days, in how many days will we be washing them on the same day?

Nastasia [14]

Answer: 60 days

Step-by-step explanation:

To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:

Multiple of 15 = 15, 30, 45, 60, 75, 90

Multiples of 20 = 20, 40, 60, 80, 100

Lowest common multiple = 60

Therefore, they'll be Washing the car on thesame day on the 60th day.

2. Write an equation in slope-intercept form that is PARALLEL to y = 2x - 2 that passes through the point (-3, 5).

Natalija [7]

Answer: y=2x+b

Step-by-step explanation:

If it is parallel, it has the same slope. So we have:

Y=2x+b

Use the point to find b

5=2(-3)+b

5=-6+b

Add 6 to both sides

11=b

Y=2x+11

Question 6 of 10

klemol [59]

Answer:

The correct option is C.

Step-by-step explanation:

The quadratic parent function is

$f(x)=x^2$

The translation is defined as

$g(x)=k(x+a)^2+b$ .... (1)

Where, k is vertical stretch, a is horizontal shift and b is vertical shift.

If |k|>1, then graph of parent function stretch vertically by factor |k| and if 0<|k|<1, then parent function compressed vertically by factor |k|. Negative k represents the reflection across x axis.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The graph shift 1 unit right,vertically stretch by a factor of 5 , reflect over the x-axis. So, a=-1, |k|=5 and k=-5

Substitute a=-1 and k=5 in equation (1).

$g(x)=-5(x+(-1))^2+(0)$

$g(x)=-5(x-1)^2$

Therefore the correct option is C.
