Answer:
x = 29
y = 10
Step-by-step explanation:
x - 3y = -1
Add 3y to both sides;
x = 3y - 1
2x - 5y = 8
Substitute x
2x - 5y = 8
2(3y - 1) - 5y = 8
Distribute;
6y - 2 - 5y = 8
Collect like terms;
y - 2 = 8
Add 2 to both sides;
y = 10
Substitute y
x - 3y = -1
x - 3(10) = -1
x - 30 = -1
Add 30 to both sides;
x = 29
Answer. 3(7-x). Good luck with this.
Answer:
x=pi*n/2+1/2arctan(7/5)
Step-by-step explanation:
5sin(2x)=7cos(2x)
5tan(2x)=7/5
2x=pi*n+arctan(7/5)
x=pi*n/2+1/2arctan(7/5) for n e Z
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = 2 and b = - 4
y = 2x - 4 ← equation of line
Answer:
c.
Step-by-step explanation:
c is the only shape on here with acute angles, the top and bottom bases are parallel w/ each other
