Segment PE has endpoints P(-4,4) and E(0,-4). Find the coordinates of point Q such that PQ:QE is 1:3. Enter the coordinates belo
Natalka [10]

Answer:

(-3, 2)

Step-by-step explanation:

Given that point Q, partitions segment PE, such that PQ:QE is 1:3, coordinates of point Q is found using the formula below:

x = \frac{mx_2 + nx_1}{m + n}

y = \frac{my_2 + ny_1}{m + n}

Where,

P(-4, 4) = (x_1, y_1)

E(0, -4) = (x_2, y_2)

m = 1, n = 3

Plug in the necessary values to find x and y coordinates for point Q as follows:

x = \frac{mx_2 + nx_1}{m + n}

x = \frac{1(0) + 3(-4)}{1 + 3}

x = \frac{0 - 12}{4}

x = \frac{-12}{4}

x = -3

y = \frac{my_2 + ny_1}{m + n}

y = \frac{1(-4) + 3(4)}{1 + 3}

y = \frac{-4 + 12}{4}

y = \frac{8}{4}

y = 2

The coordinates of the point Q are (-3, 2))

Use the graph of the function f(x) = (x + 1)² + 2. Identify the vertex and<br> the axis of symmetry.
zalisa [80]
1. Vertex: f(x)=x^2+2x+3
=> a=1 b=2
=> x=-2/2*1 => x=-2/2
=> x=-1
=> (-1,2)

2. Axis of symmetry: x=-1

Maggie wants to buy 4 roses , 6 carnations, and 9 tulips . She estimates that she will spend about $14 on these flowers. Do you
Andrew [12]
Well, 4 + 6 + 9 = 19, so $14 is a reasonable answer. If we have $19 assuming that each flower costs $1, then if the estimate is $14, that means that each flower is less than $1, which makes sense. Assuming that all of the flowers cost the same, then each flower would be about 74 cents. This would make sense considering that you are buying tulips, roses, and carnations. I really hope this helps; if not, good luck on your homework.

1.36 is 17% of x, 1.05 is y% of 15 <br><br> solve x and y
cupoosta [38]

Answer:

The answers are that x = 8 and y = 7%

Step-by-step explanation:

To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).

1.36/17% = 8

And now to find y, we divide 1.05 by 15

1.05/15 = 7%
