Answer:

1. Use the Pythagorean theorem to find AD. Show your work.

AD=9

Side BD=12, and side AB=15. We know that side AB is the hypotenuse, so AD^2+144=225

225-144=81, so side AD=9

2. Find AC. Show your work.

AC=25

To find AC, we can add AD and DC

9+16=25

3. Is ΔABC a right triangle? Explain.

ABC is a right triangle because AB^2+BC^2=AC^2

Answer:

Pythagorean theorem: a^2 + b^2 = c^2

1. we have to find a. b is 12 and c is 15 because the right angle is pointing towards 15 so that is the hypotenuse. then we simply plug the info in the equation we have above.

a^2 + 12^2 = 15^2

a^2 + 144 = 225

a^2 = 81 --> sqaure root to find the answer basically.

a = 9

- we put AD as a so AD = 9

final answer : 9

2. to find AC, simply add AD and DC.

9 + 16 = 25

final answer: AC = 25

3. ABC is not a right triangle because it does not have a right angle. the smaller triangles do, but that does not mean that ABC is a right triangle.

The table represents a liner function. What is the slope of the function?
Liono4ka [1.6K]

Answer:

The slope is 3.

Step-by-step explanation:

Let's use the slope formula to calculate the slope of this function. Remember, slope equals rise over run, or the difference between y coordinates divided by the difference between x coordinates of 2 points on the graph.

Let's use the last 2 points in the table: (1, 7) and (2, 10)

\frac{y_{2} - y_{1} }{x_{2} - x_{1} }

= \frac{10 - 7}{2 - 1}

= \frac{3}{1}

The slope of this function is 3!

Hope this helps :) Feel free to ask me any questions!

What is a equation in slope intercept form for the line that has a slope -1 that passes through (-4,3)
aleksley [76]

slope is -1

m=-1

we have a point as (-4,3)

we can use slope intercept form of line

y=mx+b

we can plug m=-1

y=-x+b

now, we can plug point (-4,3)

x=-4 and y=3 and then we can find b

3=-1*-4+b

b=-1

now, we can plug back

and we get

y=-x-1............Answer
