Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.

hopefully this helps and i didnt miss any words
Answer:
perpendicular(p)=5
base(b)=12
hypotenuese(h)=?
using pytha goras theorem,
h^2=P^2+b^2
h^2=(5)^2+(12)^2
h^2=25+144
h^2=169
h^2=13^2
h=13.
Answer:
Here's the graph I did online.
Answer:
-3/5
Step-by-step explanation:
you can use the formula 
to find the slope of a line when given two points.
we are given both the x and y intercepts, and we can use those in the formula.
the x intercept is (5,0) and the y intercept is (0,3)
i will treat (5,0) as my x1 and y1, and (0,3) as my x2 and y2
= -3/5
the slope is -3/5
