Two lines, E and F, are represented by the equations given below. Line E: 5x + 5y = 40
Line F: x + y = 8
Which statement is true about the solution to the set of equations?
a
It is (40,8).
Oь
It is (8, 40)
C
There is no solution.
There are infinitely many solutions.

d

Step-by-step explanation:

if you line e by 5 then it would be x + y = 8  they would be the same line meaning infinite solutions

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
