It is possible for a system of linear equations to have exactly 2 solutions.
Answer:
Number of Solutions
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

how do i do slope-intercepts
Answer:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
Step-by-step explanation:
area of shape A = 3cm²
number of A shape in shape B = 9 and half
1 shape A = 3cm²
9 shape A = 3×9 = 27cm²
1 half shape A = 3 ÷ 2 = 1.5cm²
area of shape B = 27cm² + 1.5cm² = 28.5cm²

Answer:
938 feet
Step-by-step explanation:
The diagonal is the hypotenuse of a right triangle with side lengths 900 ft and 264 ft. The Pythagorean theorem tells you how to compute its length.
d² = 900² +264² = 879,696
d = √879,696 ≈ 937.92 . . . . feet

10. In how many ways can a student select 7 out of 10 questions to work on an exam
Answer:
Step-by-step explanation:
7C10 = 10!/(7!)(10-7)!
7C10 = 10!/(7!)(3!)
7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)
7C10 = (10 x 9 x 8)/6
7C10 = 720/6
7C10 = 120

The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain
day 369 people entered the park, and the admission fees collected totaled 1016 dollars. How many
children and how many adults were admitted?
Answer:
184 children and 185 adults!
Step-by-step explanation:
So let's suppose there are x children who entered the park that day, then there will be (369-x) adults who entered the park that day.
So we have an equation!
1.5x+4(369-x)=1016
1.5x+1476-4x=1016
Then we swivel things around a bit.
1476-1016=4x-1.5x
2.5x=460
x=184
There are 184 children in that park that day! Wow, that's a lot of people, next we calculate the number of adults:
369-184
=185
OK, 184 children and 185 adults!
Hoped I helped! Have a nice day!

In 2010 an item costs $9.00. The price increases by 1.5% each year. How much will it be in 2030?
Answer:11.7
Step-by-step explanation:
1. Recognize variables. Starting price is 9, it’s increasing by 1.5% each year, the question asks for the price in 20 years.
2. Convert percentage to decimal. Most calculators won’t understand multiplying by percentages, and instead will understand multiplying by decimals. A decimal is something we can easily work with. It is more commonly taught to work with decimals as well. With that said 1.5% equals .015. (The number in the ones place in the percentage is always in the hundredths place when converted to a decimal, the tens to the tenths, the hundreds in the percentage to the ones place in the decimal, the hundredths in the percentage to the ten thousandths in the decimal. Basically, every individual number [the 5 in 1.5] moves two spaces to the right when going from percentage to decimal form, likewise two to the left going from decimal to percentage form. 23%=.23, 104%=1.04, 0.5%=.05, 1.234%=.01234)
3. Make your equation
20(9*(.015))+9
+9 is your starting point
9*(.015) gives you the amount the price increases per year
20 is multiplied then to that increased price for the next 20 years
4. Crunch em numbers
PEMDAS
The cost of the item in 2030 is $10.449.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Cost of an item = $9
The item increases per year = 1.5%
Now,
The equation for the cost of the item after x years.
= 9[tex](100 + 1.5)^x[/tex]
Now,
There are 10 years from 2010 to 2030.
So,
x = 10
= 9 [tex](1 + 0.015)^{10}[/tex]
= 9 x [tex]1.015^{10}[/tex]
= 9 x 1.161
= 10.449
Thus,
The item will cost $10.449 in 2030.
