Answer:
Step-by-step explanation:
the right choice is C
you use c^2=a^2+b^2
where the largest side is the hypotenuse
The answer to that is y = -6
Answer:
x=4, y=-3. (4, -3).
Step-by-step explanation:
5x+4y=8
2x-3y=17
--------------
2(5x+4y)=2(8)
-5(2x-3y)=-5(17)
---------------------
10x+8y=16
-10x+15y=-85
-----------------
23y=-69
y=-69/23
y=-3
5x+4(-3)=8
5x-12=8
5x=8+12
5x=20
x=20/5
x=4
Answer:
28+4v
Step-by-step explanation:
multiply each term in parenthesis by 4.
multiply the numbers <u>4×7</u>+4v
= the solution 28+4v
