Help me please thank you :)

Daphne has 3 days to drive 932.4 miles . she wants to have completed about 75% of the drive by the start of day three.which of t

nekit [7.7K]

So, 932.4miles (.75)=699.3miles are the miles that she wants to drive by the start of three days. so each day is 25% because of 75%/3=25%
In two days it will be 50% so, .50(932.4miles)=466.2 miles is the answer.

A line passes through (2,4) and (-2,2). find the value of y if (6,y) lies on the same line

katrin2010 [14]

Answer:

y = 6, rendering the coordinate pair: (6,6)

Step-by-step explanation:

We start by writing the equation of the line that passes through two given points on the plane: $(x_1,y_1)$ and $(x_2,y_2)$ beginning with finding the slope of the segment that joints the points using the slope formula: $slope=\frac{y_2-y_1}{x_2-x_1}$

Let's call $(x_1,y_1)$ = (2,4), and $(x_2,y_2)$ = (-2,2). Then we have the formula for the slope:

$slope=\frac{y_2-y_1}{x_2-x_1}=\frac{2-4}{-2-2} =\frac{-2}{-4} =\frac{1}{2}$

Now that we have the slope of the line, we can find the actual equation of the line by using one of the given points, and the "point-slope" form of a line with slope "m" and going through a point $(x_0,y_0)$ - which in our case we defie as one of our given points, let's say (2, 4):

$y-y_0=m\,(x-x_0)\\y-4=\frac{1}{2} (x-2)\\y-4=\frac{1}{2} x-1\\y=\frac{1}{2} x-1+4\\y=\frac{1}{2} x+3$

now we find what is the "y" value in such line that corresponds to an x-value of "6" to complete the coordinate pair (6, ?). For such we simply evaluate the equation above at x = 6:

$y=\frac{1}{2} x+3\\y=\frac{1}{2} (6)+3\\y=3+3\\y=6$

Therefore, y must be "6".

50pts and brainliest to whoever can solve this problem TWO ways: 3/7(x + 9)=12, 3/7 being a fraction

Mnenie [13.5K]

x = 19

Step-by-step explanation:

$\begin{aligned}\frac{3}{7}\left(x+9\right)&=12\\3\left(x+9\right)&=12\times 7\\3x+27&=84\\3x&=84-27\\3x&=57\\x&=\frac{57}{3}\\ x&=\underline{\underline{\bf 19}}\end{aligned}$

If 35 tickets are sold and 2 prizes are to be awarded, find the probability that one person will win both prizes if that person

PolarNik [594]

2/35 because there is still only 35 tickets and he/she buys 2. That means no matter what they have the 2 tickets. That gives them a 2 in 35 chance to win.
