Answer:
Graph the function. f(x) = 3/5x − 5 is the line
x = o : f(0) = 3/5(0) - 5 = - 5
f(x) = 0 : 3/5x - 5 =0
3/5x = 5
3x = 25
x = 25/3
you have two points A(0; -5) B( 25/3 ; 0) you can draw the graph
Answer:
one expression you could use could be, 10.25A +8.50K=total
Step-by-step explanation:
you would take 1.75 and add it to the 8.50 for the adults and 6.75 for the kids
Answer:
x = 3.5
y = 11.75
Step-by-step explanation:
-9x - 2y = -55
6x - 4y = -26
Step 1:
-2(-9x - 2y = -55) → 18x + 4y = 110
Step 2:
18x + 4y = 110
<u> 6x - 4y = -26</u>
<u> 24x </u>= <u>84</u>
24 24
x = 3.5
Step 3:
6(3.5) - 4y = -26
21 - 4y = -26
<u> -21 -21 </u>
<u> -4y </u>=<u> -47</u>
-4 -4
y = 11.75
Answer: The interest rate was 9%.
Step-by-step explanation:
If principal amount P is invested at the rate of r percent with simple interest(I) for t years, the formula to find rate :
As per given,
P = $ 500, I = $45, t = 1 year
Substitute values in formula , we get
Hence, The interest rate was 9%.
