x = price of a senior ticket
y = price of a student ticket
First day: x + 14y = $225
Second day: 7x + y = $120
Let's solve this system of equations by substitution
Subtract 14y from both sides on our first equation
First day: x = $225 - 14y
Substitute this value into our second equation for x
7($225 - 14y) + y = $120
Distribute the 7
$1575 - 98y + y = $120
Combine like terms
$1575 - 97y = $120
Subtract $1575 from both sides
-97y = -1455
Divide both sides by -97
y = $15
Plug this value into our first equation
x + 14(15) = $225
Simplify
x + $210 = $225
Subtract $210 from both sides
x = $15
The senior and student tickets cost $15
y = -X² -2x +3
What does y equal to?
Answer:
y= -1(x-1)(x+3)
Step-by-step explanation:
The way you can solve this is by factoring and using quadratics
First, you factor out the -1 in the x term
Then, you rewrite the equation into
y= -1(x^2+2x-3)
After that you factor as normal into y= -1(x-1)(x+3)

there are 614,952 pepole living in a city round this number ot the nearest thousand
Answer:
615,000
Step-by-step explanation:
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Answer:
615,000
Step-by-step explanation:
614,952
Locate the thousands place:
614,952
Check next door:
614,952
If the number is greater than or equal to 5, then we round up. If it is less than or equal to 4, we round down.
9 is greater than 5. We would round up.
614,952 ≈ 615,000

An arithmetic sequence is represented by the function f(n) = 8 + 3(n-1). What is the 4th term of the sequence?
Answer:
f(4) = 17
Step-by-step explanation:
f(n) = 8+3(n-1)
f(4) = 8+3(4-1)
f(4) = 8+3(3)
f(4) = 8+9

Answer: 41/100
Step-by-step explanation: hope this helps
Answer:
41/100
Step-by-step explanation:
All you need to do to turn a decimal into a fraction is move the decimal over however many times to get through the number and put it over "1 (+ a zero for every point you move over)"
For example if that didn't make sense:
0.645 -> 645/1000
0.4 -> 4/10
0.66 -> 66/100

Logs are stored in apile of 20 rows,with each row having one fewer log than the one below it. If there is 48 logs on the bottom row how many logs are in the pile?
Answer:
754 logs
Step-by-step explanation:
If you are starting at 48 logs on the bottom row subtracting one log for each row you go up, then you should have 28 logs in the top row.
This is because 48-20=28
now you need to find the factorial of 48 starting at 28.
Factorial is like 1+2+3+4+5=15. So it is basically just adding every single whole number that are in between 2 whole numbers.
So for this equation you would need to do: 28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48= 754.

A baker is stocking up on ingredients for the next day. She needs to bake between 32 and 48 loaves of bread. Each loaf requires 3.5 cups of flour plus an additional 0.25 cup for dusting. Complete the statement to describe the amount of flour the baker should buy to have enough flour to meet her needs without any left over.
Answer: The baker should buy a minimum of 120 cups of flour and a maximum of 180 cups.
Step-by-step explanation:
The baker should buy between 120 cups of flour to 180 cups of flour to meet her needs.
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the number of bread made from x cups of flour.
Each loaf requires 3.5 cups of flour plus an additional 0.25 cup for dusting. Hence:
y = (3.5 + 0.25)x = 3.75x
For 32 loaves:
x = 32 * 3.75 = 120
For 48 loaves:
x = 48 * 3.75 = 180
The baker should buy between 120 cups of flour to 180 cups of flour to meet her needs.
