what is the solution to the system graphed below? (1,1) (1,-1) (-1,1) (-1,-1)
Answers
Answer:
(-1, -1)
Step-by-step explanation:
The two lines intersect in the third quadrant, at (-1, -1), so that is the solution.
The solution to the system graphed below is (-1,-1) which is option D.
What is a graph?It is a collection of various points and it is used to draw lines of different functions or equations by finding out two points and by joining them.
How to identify points on the graph?We have to check solution of the system graphed in the question. There are two lines graphed. Both are intersecting each other at one point. A solution of a line exists at a point where they are intersecting. If we try to find the point then we need to identify origin first and then according to x and y axis points will be found. The required points will be (-1,-1).
Hence the solution of graphed system is (-1,-1).

B) 1 and 5
C) 3 and 5
D) 7 and 2
will mark brainliest if correct and give 50 pts.
Answers
Supplementary angles are angles that add up to 180 degrees, aka one straight line. The supplementary angles here are:
1 and 2, 1 and 3, 2 and 4, 3 and 4, 5 and 6, 6 and 8, 7 and 8, and 6 and 7. Well, those are the more obvious ones. 1 and 7 are supplementary because if you envision them next to each other, you’ll see that they create a straight line. So, with that logic, 3 and 5 are supplementary because when you put them together, they create a straight line
Angle ∠5 and angle ∠3 are supplementary angles. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
From the figure, the supplementary are given below.
The angles ∠1 and ∠2, ∠3 and ∠4, ∠5 and ∠6, ∠7 and ∠8, ∠1 and ∠3, ∠2 and ∠4, ∠5 and ∠7, and ∠6 and ∠8 are supplementary angles.
The sum of angle ∠5 and angle ∠3 is 180 degrees.

Colin invests £1200 into his bank account. He receives 3% per year simple interest. How much will Colin have after 4 years? Give your answer to the nearest penny where appropriate.
Answers
Colin will have £1344 in his bank account after 4 years. This is calculated using the simple interest formula I = PRT (Interest = Principal x Rate x Time) yielding an interest earned of £144 over four years, which was then added to the initial investment.
Explanation:First, understand that simple interest is calculated as (principal amount × interest rate × time in years). The principal amount here is £1200, the interest rate is 3%, and the time period is 4 years.
Before doing the calculation, convert the 3% interest rate into decimal form by dividing by 100, yielding 0.03.
War is represented by the formula I = PRT, which means Interest = Principal x Rate x Time. So, use these values in the formula: £1200 * 0.03 * 4. This gives you £144, which is the interest earned after 4 years.
To find the total amount in Colin's account after 4 years, you need to add the interest earned to the principal amount. Therefore, £1200 (original amount) + £144 (interest) = £1344.
So, after 4 years, Colin will have £1344 in his bank account.

Suppose that you ask three friends to go to the mall. Each one has a 0.70 chance of saying yes. What is the probability that all three friends will say they can go to the mall with you? a. 0.027 c. 0.343 b. 0.21 d. 0.657
Answers
____________________________________________________
Answer:
Your answer would be 0.343.
____________________________________________________
Step-by-step explanation:
In the probability questions like this one, in order to get the answer,we would use the multiplication rule.
In your questions, we are trying to find the probability of ALL of your friends going to the mall with you.
Lets make it easier for you.
Whenever in probability you can say and, you multiply.
This means that you would try to find if friend 1 and friend 2 and friend 3 will say yes.
That's the same as saying friend 1's probability × friend 2's probability × friend 3's probability
We know that each friend has a 0.70 chance of saying yes.
Using the multiplication rule, we would just multiply 0.7 three times.
[tex]0.7 *0.7*0.7=0.343[/tex]
When you multiply, you should get 0.343.
There is a 0.343 chance of ALL your friends saying yes to go to the mall with you.
0.343 would be your FINAL answer.
____________________________________________________
To solve this problem, you need to consider the probability of each friend agreeing to go to the mall individually, then multiply these probabilities together to find the probability that all three will say yes.
Since each friend has a 0.70 chance of saying yes, we can calculate the combined probability as follows:
For the first friend, the probability is 0.70.
For the second friend, the probability is also 0.70.
For the third friend, the probability remains 0.70.
To find the combined probability that all three friends will say yes, we multiply the individual probabilities together:
\( Probability (All Say Yes) = Probability (Friend1 says Yes) \times Probability (Friend2 says Yes) \times Probability (Friend3 says Yes) \)
\( Probability (All Say Yes) = 0.70 \times 0.70 \times 0.70 \)
When you calculate this, you get:
\( Probability (All Say Yes) = 0.343 \)
So the answer is c. 0.343.

Find the vertical, horizontal, and slant asymptotes, if any, for f(x)=5x^3-51x^2+77x+100/x^2-11x+24
Answers
Answer:
Step-by-step explanation:
Given: f(x)=5x^3-51x^2+77x+100/x^2-11x+24
Please use parentheses to eliminate any ambiguity:
f(x) = (5x^3-51x^2+77x+100) / (x^2 - 11x + 24)
or (better yet):
5x^3-51x^2+77x+100
f(x) = ---------------------------------
x^2 - 11x + 24
The vertical asymptotes here are at the zeros of the denominator:
x^2 - 11x + 24 = 0, This quadratic equation has coefficients a = 1, b = -11 and c = 24. Thus, its roots (zeros) are:
-(-11) ± √( 121 - 4(1)(24) )
x = -------------------------------------
2(1)
or:
11 ± √( 25 )
x = --------------------
2
or: x = 8 and x = 3
The vertical asymptotes are x = 8 and x = 3.
If we attempt to divide x^2 - 11x + 24 into 5x^3 - 51x^2 + 77x + 100, we see that the first term of the quotient is 5x. As x increases or decreases without bound, 5x goes to either ∞ or -∞, so we conclude that there is no horiz. asymptote. Continuing this division results in:
5x + 4 + a fraction
This represents the slant asymptote, y = 5x + 4
