Answer:
f(-2) = -15
Step-by-step explanation:
f(x) = 5x-5
Let x = -2
f(-2) = 5(-2) -5
= -10 -5
=-15

Answer:
2.5 years
Step-by-step explanation:
Given data
P=9000
r= 1.25%
A= 9281.25
The simple interest expression is given as
A=P(1+rt)
substitute
9281.25= 9000(1+0.0125*t)
9281.25=9000+112.5t
collect like terms
9281.25-9000=112.5t
281.25= 112.5t
t= 281.25/112.5
t= 2.5
Hence the time is 2.5 years

ANSWER
3x+4y=10 …………..(1)
2x−2y=2 (or) x−y=1 …………(2)
(1) ⇒(3x+4y=10)1
(2) ⇒(x−y=1)3
_____________________
3x+4y=10
3x−3y=3
_____________________
7y=7
∴y=1
Put y=1 in (1) we get 3x+4×1=10
3x=10−4=6
∴x=36=2
Hence x=2,y=1.
Answer: A= 460 mm2
Step-by-step explanation:
Hi, since the circumference formula is :
C = 2 π r
Where r is the radius, we can solve the formula for the radius replacing with the value given:
76 =2 π r
76 / (2 π) = r
r = 12.1 mm
Now , we have to apply the formula for the area of a circle.
A = π r^2
A = π (12.1)^2
A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)
