Answer:
13
Step-by-step explanation:
Draw a picture!
You have a right triangle with legs of 5 and 12.
By the Pythagorean Theorem, the hypotenuse is √(5²+12²) = 13
Answer:
Its the first one
Step-by-step explanation:
Answer:
(using substitution to solve the problem)
x=y-3
2x+y=12
2(y-3)+y=12
2y-6+y=12
3y=18
y=6
y=6
x=6-3
= (3, 6)
Step-by-step explanation:
using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.
i hope this helps :)
Answer:

Step-by-step explanation:
Choices aren't given, so i will solve this equation and find the first positive x-intercept angle.
First, x-intercept means the x-cutting point of the graph. This occurs when y = 0. So we will solve the equation for x. Shown below:

Inverse Cotangent (ArcCot) of 0 is at
, so we can now solve for x:

So, the x-intercept is at x = pi/6
Answer:
y=-1/2x+2
Step-by-step explanation:
for x-intercept
put y=0
0= -1/2x+2
1/2x=2
x=4
(4,0)
for y-intercept
put x=0
y= 2
(0,2)
