Answer:

6.33

Step-by-step explanation:

Given the coordinates;

G(-4,2), O(5,-1), and T(10,8).

Midpoint of GT is expressed as;

M = (-4+10/2, 2+8/2)

M = (6/2, 10/2)

M = (3, 5)

Hence the midpoint of GT is (3,5)

Find the length of M and O

M (3,5) and O(5,-1)

MO = √(3-5)²+(5+1)²

MO = √2²+6²

MO = √4+36

MO = √40

MO  = 6.33

Hence the length of the segment joining the midpoint of GT and O is 6.33

Lines m and n are parallel. Line m is described by y=4x+2. Line n contains the point (1, -3). Which of the following is an equat
Semmy [17]

The equation of <em>line m</em>, in point-slope form is: y + 3 = 4(x - 1)

<em><u>Recall:</u></em>

  • The slopes of parallel lines are equal to each other.
  • Slope-intercept form equation is: y = mx + b, where m is slope and b is y-intercept.
  • Point-slope form equation is: y - y_1 = m(x - x_1) where, (x_1, y_1) is a point and m is the slope.

Equation of line m is y = 4x + 2

Slope of line m is 4

Since line m and line n are parallel, both lines will have the same slope. Therefore, the slope of line n is 4.

To write the equation for line if it contains the point (1, -3), substitute (x_1, y_1) = (1, -3) and m = 4 into y - y_1 = m(x - x_1):

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

Therefore, the equation of <em>line n</em>, in point-slope form is: y + 3 = 4(x - 1)

Alex17521 [72]
Nayeli - 4x19= 76 total candies
jayden- 5x15= 75 total candies
so nayeli has 1 more piece of candy than jayden does.

Which shows a perfect square trinomial?
anastassius [24]
The answer is <span>c. 16x2 + 24xy + 9y2.

Since we need trinomial (three term expression) choices a and b are incorrect because they have only two terms.

So, our square trinomial is a</span>² + 2ab + b² or a² - 2ab + b²
a² + 2ab + b² = (a + b)²
a² - 2ab + b² = (a - b)²

Let's check choices c and d:
c) 16x² + 24xy + 9y²
a² = 16x²
a² = (4x)²
a = 4x

b² = 9y²
b² = (3y)²
b = 3y

a² + 2ab + b² = (4x)² + 2 * 4x * 3y + (3y)² = 16x² + 24xy + 9y²
CORRECT

d) 49x² - 70xy + 10y²
a² = 49x²
a² = (7x)²
a = 7x

b² = 10y²
b² = (y√10)²
b = y√10

a² + 2ab + b² = (7x)² + 2 * 7x * y√10 + (y√10)² = 49x² + 14xy√10 + 10y²
INCORRECT

So, c) is correct answer
