Answer:
x=0 y=-11 (0,-11)
Step-by-step explanation:
1. take what y equals (3x-11) and plug it in for y in the second equation
Should look like this: O= 6x-2(3x-11)-22
2. Then distribute O=6x-6x+22-22
3. Then combine like terms O= 0 the 22's cancel out as well as the x's
x= 0
4. plug 0 in for x in the first equation y=3(0)-11
5. y= -11
6. x=0 y=-11 (0,-11)
There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Key skills needed: Probability, Possible Outcomes
1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8
That means there are 8 numbers on the spinner.
2) The problem asks what is the probability that the spinner will not land on 5 or the 8.
To calculate this --> [tex]\frac{acceptedoutcomes}{total}[/tex]
3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7
That is 6 accepted outcomes.
4) The total outcomes is 8 (since there are numbers the spinner can land on).
5) Therefore, the answer would be [tex]\frac{6}{8}[/tex]
[tex]\frac{6}{8}[/tex] can be simplified into [tex]\frac{3}{4}[/tex] as both the numerator (6) and the denominator (8) share a factor of 2.
6) With this --> [tex]\frac{3}{4}[/tex] is the answer.

3/10 and 2/5
1/3 and 3/4
THESE TWO ONLY!
Answer:
3/10 and 2/5 = 3/10 and 4/10
1/3 and 3/4 = 4/12 and 9/12
Step-by-step explanation:
For 3/10 and 2/5
* Find the lcm (least common multiple) of the denominators which are 10 and
5. The multiples of 10 are: 10, 20, 30 etc and the multiples of 5 are: 5, 10 15,
etc. So, the lcm is 10. It is the smallest multiple that the denomitaotrs share.
* Next multiply the numerators (3 and 2) by whatever number you use to
multiply the denominator by to get 10. For 3/10, the denominator stayed the
same, so to get 10, you need to multiply 10 by 1. Do the same for the
numerator. 3 x 1 = 3. So, the first factor pair is 3/10.
* The second factor pair is 2/5, so we are still using the lcm of 10. So, what
do you need to multiply 5 by to get 10? The answer is 2. Now just multiply
the numerator (2) by 2 and you get 4. The second factor pair is now 4/10.
Jennifer opened a savings account a year ago. Her savings account earned $12 in interest and now has a balance of $1012. What was her initial investment (principal)?
Answer:
I think its $1000
Step-by-step explanation:
if she earned $12 the 1012-12=1000
Answer:
I really don't know much but this is what I know
If she has $12 dollars in interest and a year later she has $1012 making it so she earned EXACTLY $1,000 in the time being.

What is the radius of the circle shown, given that point P is its center?
A)13.5 ft
B)27 ft
C)54.5 ft
D)729 ft. PLSSS HELP ASAP
The radius of the circle with point P as its center is 13.5 ft.
A circle is the locus of a point such that its distance from a fixed point is always constant (the same).
The diameter of a circle is a straight line segment that passes through the center of the circle and has endpoints on the circle.
The radius of a circle is half the diameter of the circle.
Given that the diameter of the circle is 27 ft. hence, the radius of the circle is:
Radius = Diameter / 2
Radius = 27 ft / 2 = 13.5 ft.
Hence the radius of the circle is 13.5 ft.

The circumference of this tabletop is 24π inches, Which of the following best describes how to determine the area of the tabletop?
A) Multiply 2(24) to calculate the diameter. Then multiply the diameter by π
B Find half of 24 to calculate the radius. Then multiply the radius by π.
C Multiply 2(24) to calculate the diameter. Then square the diameter and multiply the result by it π
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Answer:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Step-by-step explanation:
Given that circumference of circle is: [tex]24 \pi[/tex]
The formula for circumference of circle is:
[tex]C = 2\pi r[/tex]
Comparing both formulas, we get
[tex]24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12[/tex]
The radius is obtained by dividing 24 by 2.
We also know that the area of circle is:
[tex]A = \pi r^2[/tex]
The radius is being squared and then multiplied by pi to get the area.
Hence,
The correct answer is:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.

R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
R3 = {(x, y) (y, z) (z, t) (t, v)}
R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images

A store marks its merchandise up 225% from the price it pays. The store buys a bag of chips for $1.20. How much will the store charge for the bag of chips? (PLS give an explanation too!!)
Answer:
$3.90
Step-by-step explanation:
multiply 1.20 x 2.25 and add the answer to 1.20
They would have to add that change up to cents because the store marks up to 225% from the prince it’s pays and we only add the 25 because if we add the 225 that changes the dollar that’s suppose to stay as 1$.
20+25=46 cents. U know it’s equals 45 cents because it’s just like counting by fives.
Sorry this is all I know about this problem.
