Answer:
(x,y) (-6,2)
Step-by-step explanation:
3x+11y =4
-2x-6y=0
3x+11y = 4
x= -3y ( add this for x)
3(-3y) +11y =4
-9 +11y =4
2y = 4
y = 2
slove for x now
x =3x2
x = -6
answer
(x,y)(-6,2)

Solving for x you get the answer
ERROR ANALYSIS Describe and correct the error in
graphing and comparing
y= x^2and y = 0.5x^2.
Answers
Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph
Need answer fast please. Which line is perpendicular to y = x + 2 and passes through (4,-1)?
y = -x+1
y = -x + 3
y = -x + 2
y = -x +4
Answers
Answer:
C. y = -x + 3
Step-by-step explanation:
y = x + 2
Find perpendicular slope (opposite reciprocal):
x/1 --> -1/x or -x
Convert to point-slope form:
y - (-1) = -1 (x - 4)
y + 1 = -1x + 4
y = -x + 3

Write 3-5 sentences about why you should receive brainliest. Best answer gets brainliest. ::)
Answers
Answer:
First off, I LOVE helping people even if I'm not a professor teacher, or tutor. However, I always do my best to answer the questions as close to perfection as possible even if it can take an hour. I want people to easier to understand and leaner better when I gave an answer to their question, by doing that, I felt very proud of myself and felt like I accomplished a goal. I'm still very young and just started using Brainly, so I don't really know what a brainlist is (DON'T LAUGH). Even so, if you don't think that I deserve the brainlist, it's fine because once I'm older and have more experience, I could help more and more people with their questions or problems. If you actually gave me a brainlist, I'll be really grateful and I might give you a brainlist if you answered my questions. Anyway, when I received a brainnlist, the first thing that came up in my mind is that my answers are actually useful for once. P.s. if you give a brainlist, Thank u

you install 618 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 152 feet. What is the length of the yard?
Answers
Answer:
The length of the yard is 157 feet
Step-by-step explanation:
P= L+L+W+W or 2L+2W. (P is perimeter, L is length, and W is width.)
Substitute in known values for the variables.
618=2L+2(152)
Multiply.
618=2L+304
Now solve for L by doing inverse operations (subtract).
314=2L
Divide.
L=157
So the yard is 157 feet long.

x approximately = 11.971, y approximately = 0.837
Step-by-step explanation:
the 12 ft is the hypotenuse of the right angle triangle formed
Cos (theta) = adjacent/hypotenuse
so Cos(4) = x/12, solving for x = 11.971
Sin(theta) = opposite/hypotenuse
so Sin(4) = y/12, solving for y = 0.837

Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same operations. Is Larry correct?
Answers
Answer:
Larry is wrong
Step-by-step explanation:
Multiplying big numbers will give significantly bigger results then multiplying smaller numbers then adding them. 14 + 12 = 26 & 8 + 12 = 20. 14 x 12 = 68 & 8 x 12 = 96. 96 + 168 is alot less then 26 * 20 so that is why larry is wrong
