if you solve using subsitution, the point form would be (2,1) and the equation form = 2, y=1
Answer:
x = -2
y = -23
(x, y) --> ( -2, -23)
Step-by-step explanation:
y = 6x - 11
-2x - 3y = -7
***What you need to do is substitute the "y" with what has been given to us which is "6x - 11"***
-2x - 3(6x - 11) = -7
Now what you need to do, is use the distributive property (multiply what is in the parenthesis "6x - 11" by what is outside of it "3").
-3 × 6x and -3 × -11
-18x and 33
Now we have......
-2x - 18x + 33 = -7
Now we can combine like terms (put the numbers that are the same together - variables with variables, and whole numbers with whole numbers)
-2x - 18x = -20x (2 negatives added together gives u a result of a bigger negative number)
-20x + 33 = -7
Now we need to subtract 33 on both sides
-20x + 33 - 33 = -7 - 33
-20x = -40
Now we need to divide by -20 on both sides to isolate the variable
-20x ÷ -20 = -40 ÷ 20
x = -2
Now that we have what "x" is, we can use that to find what "y" is....
y = 6x - 11
Substitute the "x" with the answer we got "-2".
y = 6(-2) - 11
y = -12 - 11
y = -23
x = -2
y = -23
Now we can check our work
y = 6x - 11
All we need to do is substitute the "x" and "y" with the answer we got above.
y = 6x - 11
-23 = 6(-2) - 11
-23 = -12 - 11
-23 = -23
CORRECT
So now that we checked our work, and saw that it was correct, I can hereby say that x is -2 and y is -23
x = -2
y = -23
(x, y) --> ( -2, -23)
Hope this helped!!!
Out of the 4,500 people who attend the rock concert, forty-six percent purchase a T-shirt. How many people buy T-shirts?

if a triangle has three degrees that measure 75, 75 and 30, what type of triangle is it equilateral, scalene, isosceles
Answer:
it is Isoscales triangle
Step-by-step explanation:
it is Isoscales triangle because Isoscales triangle is the triangle having atheist two sides or angle equal and in that question there is two 75
[tex] \huge\sf \pink{A} \sf \red{n} \sf \orange{s} \sf \blue{w} \sf \green{e} \sf \purple{r}[/tex]
It is an isosceles triangle.
[tex] \huge\sf \pink{R} \sf \red{e} \sf \orange{a} \sf \blue{s} \sf \green{o} \sf \purple{n}[/tex]
Because it's 2 of sides are equal and one is different.

Also,This triangle have two sides with equal length.
15. a
16.c
17. e
18.9
19. h
Answer:
19 h
Step-by-step explanation:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

Use the quadratic equation y = –2x^2 + 4x +5 to complete the statements.
Answer:
Step-by-step explanation:
Given quadratic equation is,
y = -2x² + 4x + 5
y = -2(x² - 2x) + 5
y = -2(x² - 2x + 1 - 1) + 5
y = -2(x² - 2x + 1) + 2 + 5
y = -2(x - 1)² + 7
This equation is in the vertex form of the quadratic equation,
y = a(x - h)² + k
where, (h, k) is the vertex of the parabola.
Therefore, vertex of the given quadratic equation is (1, 7)
The equation can be rewritten as y = -2(x - 1)² + 7.
Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).

B. Noah writes the equation 3 (x+7)=57 to represent the situation. DO YOU agree with him? Explain your answer.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.
What is the partial fraction decomposition of
7x squared- 6x +9/
3x(4x squared +9)
9514 1404 393
Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
[tex]\dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}[/tex]

whoever answers first and at least looks correct gets brainliest!!!
Answer:
2x - 1
Step-by-step explanation:
Simplify. Note that you cannot combine a term with a variable with a constant term. Divide 5 from both terms in the parenthesis:
1/5(10x - 5) = (10x - 5)/5
Divide 5 from both terms in the parenthesis:
10x/5 = 2x
-5/5 = -1
2x - 1 is your answer.
