Answer:
9)=95°
10)=120°
Step-by-step explanation:
9) = 10x+5 = -4+11x - vertically opposite
or, 5+4 = 11x-10x
or, x = 9
now
10x+5
= 10*9+5
= 90+5
= 95
9)= 95°
10)= soln
16x-4+31x-4=180-being cointerior
or, 47x-8=180
or, 47x= 188
so, x = 4
now
31x-4
= 31.4-4
=124-4
=120
10)=120°
Answer:
Jenn's account has a greater simple interest rate.
Lindsey's interest in 1 year was $3
Jenn's interest in 2 years was $7.50 if you divide $7.50 by 2 the answer would be 3.75 therefore Jenn's account has the greater simple interest rate.
Answer:
20
Step-by-step explanation:
we first find the formula of the line
y = mx+b
m = (y2-y1)/(x2-x1)
m = 10/10
m = 1
y = 1x + b
y = x + b
plug in points from the table
10 = -10 + b
20 = b
b = 20
b is the y-intercept
