I'm really sorry, but I only know the first question.
The answer is 340.
Answer:
C multiply the first equation by 3
Step-by-step explanation:
3x-y =5
2x+3y = 10
We want to eliminate y
Since the first equation has a negative 1y and the second equation has 3y
I would multiply the first equation by 3 and then the y's cancel
3(3x-y =5)
9x -3y = 15
2x+3y = 10
------------------
11x = 25
Answer:
Oh...okay
Step-by-step explanation:
Answer:
1: x-intercept(s): (
,0)
y-intercept(s): (0,10)
2: x-intercept(s): (13,0)
y-intercept(s): (0,−
)
Step-by-step explanation:
A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer
