Answer:
John’s age is 8 years
Step-by-step explanation:
Let
x -----> John’s father's age
y -----> John’s age
z -----> John’s sister's age
we know that
-----> equation A
-----> equation B
-----> equation C
Substitute equation A and equation B in equation C and solve for y
Multiply by 2 both sides to remove the fraction
<em>Find the value of x</em>
<em>Find the value of z</em>
therefore
John’s father's age is 40 years
John’s age is 8 years
John’s sister's age is 4 years
4d² / (d+1) when d=3;
therefore:
4(3)² / (3+1)=4(9) / 4=9
Answer:4d² / (d+1) when d=3 is equal to 9.
#1
(-1,1)
#2
(-1,-5)
#3
last one
#4
y = x - 3(third one)
(a) it is always true -5.2 x ( -1.4 ) =7.28 AND -1.4 x (-3.6) =5.04
(b)the rule for multiplying negatives is negative x negative = positive.
