Answer:

The third one is the only one that is not a function.

Step-by-step explanation:

5. Find the point P along the directed line segment from X(-3, 3) to Y(6,-3) that divides
ASHA 777 [7]
Consider point P(x,y) such that P, X and Y are collinear,

As vectors

XP = XO + OZ where O(0,0)
XP = OZ - OX
XP= (x,y) - (-3,3)
XP = (x+3, y-3)

Similarly,

PY = (6-x, -3-y)

But XP= 2^PY

[x+3, y-3] = [2(6-x), 2(-3-y)]

Given both vectors are equal, as they go in the same direction, Solve for x and y accordingly:

x+3 = 12 - 2x

x = 3

y-3 = -6-2y

y = -1

Therefore, P(3,-1)

Please answer this correctly
MAVERICK [17]

Answer:

1:50 PM

Step-by-step explanation:

Left school at 10:38 AM,

took them 51 minutes,

38+51=89,

89-60=29,

so when they drove to the museum, it was 11:29 AM.

From here, they stayed at the museum for 1 hour and 26 minutes,

so they stayed at the museum until 12:55 AM since 29+26=55.

Now, it took them 55 minutes to drive back to the school,

so 12:55 plus another 55 minutes,

it's going to be 1:50 PM when Dale's class got back to school.

What is the graph description for y=-10x
Serga [27]
Y = - 10x has a negative slope, m = -10, and a y-intercept of (0, 0).

The graph includes the following points:

{(-2, 20), (-1, 10), (0, 0), (1, -10), (2, -20)}.

Attached is a screenshot of the graph, where it includes the y-intercept crossing along the point of origin, (0, 0).

NEED HELP I WILL MARK BRAINLIST AND DO NOT SPAM
gavmur [86]

Answer: it will take 14 years

Step-by-step explanation:

A savings account is started with an initial deposit of $600. This means that the principal P is

P = 600

It was compounded annually. This means that it was compounded once in a year. Therefore,

n = 1

The rate at which the principal was compounded is 2.1%. So

r = 2.1/100 = 0.021

The duration of time that for which the money stayed in the account is t years. So

Time = t

The formula for compound interest is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years. Therefore,

a) the equation to represent the amount of money in the account as a function of time in years would be

A = 600 (1+0.021/1)^1×t

A = 600 (1.021)^t

b) the amount of time it takes for the account balance to reach $800 would be

800 = 600 (1.021)^t

Dividing both sides of the equation by 600, it becomes

1.33 = (1.021)^t

t = 14
