Y = -3x + 13
Steps and the graph are on paper
Answer:
The answer will be listed below.
Step-by-step explanation:
First of all, you want x to by itself, so distribute the three to both x and negative 4 so you'll get 3x-12=2x+6.
Now, subtract 2x from both sides and add 12 to both sides and you'll get an answer of x=19. From that, you are able conclude that this equation has one solution.
Answer:
A
Step-by-step explanation:
I know that 20 times 7 is 140 and if I take away 2 sevens that leaves 126. So 126 \div 7 = 18
Answer:
Remaining tickets left to distribute, A = (300 - 10m)
Step-by-step explanation:
a) Let the number of choir members be m
Let the number of tickets remaining after the distribution be A
Each choir member is to get 10 tickets each.
Number of tickets to be given to the members = 10m
original number of tickets = 300
So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)
b) The independent variable in this expression is m (the number of choir members)
And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)
Hope this Helps!!!
Step-by-step explanation:
Take n common
n(n²+2n-15)=0
now factorise the quadratic one as n when goes to RHS it becomes zero
n²-3n+5n-15=0
n(n-3)+5(n-3)=0
n=3,-5
