5x + 2y = 7 10x + 4y = 14
Answers
10x+4y=14
divide second euqtion by 2
5x+2y=7
5x+2y=7
they are same
the solution is any oint on the line 5x+2y=7
some points are
(1,1)
(0,3.5)
(1.4,0)
etc
infinitely many

D. 6x+2y=2 @Mathematics
Answers
y=mx + b , where m is the slope. If two lines are parallel they have equal slopes. So first step is to transform these equations to common form:
A) y=-3x+2
B) x-3y =-3
-3 y =- x-3 / :(-3)
y = 1/3 x +1, 1/3 ≠ -3
C) 3x + y = -6
y = -3x - 6
D) 6x + 2 y = 2
2y= - 6x+2 /:2
y = -3x +1
Answer:B)
choice A. y=-3x+2 is right so can being the equation of second line
choice B. x-3y =-3
-3y = -3-x
3y = 3+x
y = 3/3 +x/3
y = 1 + x/3 so this equation not can being the equation of second line sure

Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = £600
r = 3.2% = 3.2/100 = 0.32
n = 1 because it was compounded once in a year.
t = 6 years
Therefore,.
A = 600(1 + 0.032/1)^1 × 6
A = 600(1.032)^6
A = £724.82

Answer:
a. 32
b. 32
Step-by-step explanation:
a. 12 + 4y
They gave us the value of "y" which is "5", and substitute that into the expression.
12 + 4y
12 + 4(5)
12 + 20
32
b. 4 (y + 3)
They gave us the value of "y" which is "5", and substitute that into the expression.
4 ( y + 3 )
4 ( 5 + 3)
Distributive property (multiply what is in the parenthesis by what is out of it (4))
4 * 5 + 4 * 3
20 + 12
32
