-18=7-4y
-7 -7
________
-25=-4y
___ ___
-4 -4
y= 6.25
Answer:
Step-by-step explanation:
- -2n +7 > -11
- -2n > -11 - 7
- -2n > -18
- n < -18/-2
- n < 9
- n = (-oo, 9)
Answer:
D) 5
Step-by-step explanation:
a²+b²=c²
12²+b²=13²
144+b²=169
b²=169-144
b²=25
b=√25
b=5
Take the formula: y=mx+b
m= slope
b=y-intercept
m=2
b=-1
therefore:
y=2x-1
#2 part b. the equation is 100+3x+2x=180 and part c. is 3x=48 and 2x=32
