A cross between two heterozygous pea plants with yellow seeds

Mekhanik [1.2K]

Okay all you have to do is complete the square of the x and y's
so divide the coefficient of x by -2, then square it all and minus the square of the coefficient of x
hence (x-3)^2 - 9
then do the same for y
(y-4)^2 - 16
so (x+3)^2 + (y+4)^2 = 36
the radius is the root of the 36 so 6, and the centre is (-3,-4) because it's whatever would make the (x+3) or (y+4) equal to 0

a big cruise ship dropped anchor off the Caribbean island of antigua. the heavy anchor dropped into the water at a rate of 2.5 m

AysviL [449]

Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell

(2.5 m/s) x (45 s) = 112.5 meters .

If it wound up only 40 meters underwater, then it must have fallen

(112.5 m - 40 m) = 72.5 meters

from its storage position on the big cruise ship,
before it ever reached the water.

Since it was falling at the rate of 2.5 m/s, it took

(72.5 m) / (2.5 m/s) = 29 seconds

to get down to the water surface after it started dropping.

What is the answer for this math problem

Answer:

The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) ⇒ D

Step-by-step explanation:

<em>To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line</em>

The form of the linear equation is y = m x + b, where

m is the slope of the line

b is the y-intercept (value y at x = 0

The rule of the slope of the line that passes through points (x1, y1) and (x2, y2) is m = $\frac{y2-y1}{x2-x1}$

From the given figure

∵ The line passes through points (-4, 0) and (0, 4)

∴ x1 = -4 and y1 = 0

∴ x2 = 0 and y2 = 4

→ Substitute them in the rule above

∵ m = $\frac{4-0}{0--4}$ = $\frac{4}{0+4}$ = $\frac{4}{4}$

∴ m = 1

∵ b is the value of y at x = 0

∵ y = 4 at x = 0

∴ b = 4

→ Substitute the values of m and b in the form of the equation above

∴ y = 1(x) + 4

∴ y = x + 4 ⇒ equation of the given line

Let us check every group

∵ The ordered pairs are (7, 3), (6, 2), (2, -2)

∵ y = x + 4

∵ x = 7

∵ y = 7 + 4 = 11

∵ y-coordinate = 3

∴ Point (7, 3) doesn't lie on the line

∵ The ordered pairs are (5, 1), (3, 7), (2, 6)

∵ x = 5

∴ y = 5 + 4 = 9

∵ y-coordinate = 1

∴ Point (5, 1) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = 2

∴ y = 6

∵ y-coordinate = 2

∴ Point (2, 2) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (-2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = -2

∴ y = -2 + 4 = 2

∵ y-coordinate = 2

∴ Point (-2, 2) lies on the line

∵ The three ordered pairs lie on the line

∴ The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)

∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)

∵ x = 1

∴ y = 1 + 4 = 5

∵ y-coordinate = 5

∴ Point (1, 5) lies on the line

∵ x = -6

∴ y = -6 + 4 = -2

∵ y-coordinate = 2

∴ Point (-6, 2) doesn't lie on the line
