Answer:

A: (-3, 1.5)

Step-by-step explanation:

((-5.5, -6.1) + (-0.5, 9.1))/2 = (-6, 3)/2 = (-3, 1.5)

The midpoint coordinates are the average of the two end point coordinates. Add them up and divide by 2.

George's total points is 5 less than susan's total points. Does geroge need more points or fewer susan points?

Firdavs [7]

Answer: Need more points.

Step-by-step explanation:

If George's total point is 5 less than susan's points then George needs more points to make up to susan or pass susan's points.

For example ,

g = s - 5 where g is George's points and s is susan's point.

As you can see for G to catch up with s you will need 5 more points.

Hello I need help on this question!

Sloan [31]

Answer:

Step-by-step explanation:

Refer to attachment for marking of sides.

In the given figure , ∆ABC , ∆ABD and ∆ADC are right angled triangles . Therefore here we can use the Pythagoras theorem , as ,

$\longrightarrow$ base² + perpendicular² = hypotenuse ² .

• In ∆ABD , we have ;

$\longrightarrow$ AB² + BD² = AD²

$\longrightarrow$ AB² + x² = 10²

$\longrightarrow$ AB² = 10² - x²

$\longrightarrow$ AB² = 100 - x²

$\rule{200}2$

• Again in ∆ADC , we have ;

$\longrightarrow$ AC² + AD² = CD²

$\longrightarrow$ AC² = 20² - 10²

$\longrightarrow$ AC² = 400 - 100

$\longrightarrow$ AC² = 300

$\rule{200}2$

Again in ∆ABC , we have ,

$\longrightarrow$ AC² = AB² + BC²

Substituting the values from above ,

$\longrightarrow$ 300 = 100-x² + (20-x)²

$\longrightarrow$ 300 = 100 - x² + 400 + x² - 40x

$\longrightarrow$ 40x = 500 - 300

$\longrightarrow$ 40x = 200

$\longrightarrow$ x = 200/40

$\longrightarrow$ x = 5

<h3>Hence the required answer is 5 .</h3>

WITCHER [35]

Answer:

the answer is D. Y=3/2x+6

Step-by-step explanation:

in the equation y=mx+b, b stands for the y intercept, which in this case is 6.

The measure of the first angle in a right triangle is 10 less than the measure of the second angle.The third angle is the right

prohojiy [21]

Triangle angles add up to a total of 180 degrees.

X will substitute for the second angle.

(X - 10) will substitute for the first angle, which is 10 less than the second angle (x).

The third angle is a right angle which is 90 degrees.

The equation therefore, the summation of the angles:
90 + x + (x - 10) = 180

Join like terms:
80 + 2x = 180

Solve for x:
2x = 100
x = 50

This means that:
The second angle is 50.
The first angle is 50 - 10 which is 40.

We can double check by adding the angles 50, 40, and 90 together to get 180.
