Given:
The equation of line is

To find:
The x and y-intercept of the given line.
Solution:
We have,

Putting x=0, we get

Add 6 on both sides.


Divide both sides by 4.

So, the y-intercept is
.
Putting y=0 in given equation, we get

Add 5 on both sides.


Divide both sides by 7.

So, the x-intercept is
.
Answer:
B) 6, 8, 10
Step-by-step explanation:
All right triangles will follow the following theorem (Pythagorean theorem):
, where
and
are two legs of the triangle and
is the hypotenuse. Out of all answer choices, only B) 6, 8, 10 follow this theorem.
Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
