Answer:
(x, y) = (-1, 5/2)
Step-by-step explanation:
The only variable with a coefficient that has a magnitude of 1 is x in the first equation. Using that equation, we can write an expression for x:
x = 2y -6
This can be substituted for x in the second equation.
(7/2)(2y -6) +7y = 14
7y -21 +7y = 14 . . . . . . eliminate parentheses
14y = 35 . . . . . . . . . . . add 21
y = 35/14 = 5/2 . . . . . divide by the coefficient of y
x = 2(5/2) -6 = -1
The solution is (x, y) = (-1, 5/2).

Present age of the Victor as per given condition of the equation formed is equals to [tex]30[/tex] years.
What is equation?" Equation is defined as the relation between the variables and numbers using the sign of equality."
According to the question,
[tex]'x'[/tex] represents the present age of the Victor
[tex]'x+10'[/tex] represents the age of the Victor 10 years now
[tex]'x-10'[/tex] represents the age of the Victor 10 years ago
As per condition given equation we get,
[tex]x-10 = \frac{1}{2} (x+10)[/tex]
Simplify the equation to get the present age ,
[tex]2(x-10) = x+10\\ \\\implies 2x-20 = x+10\\\\\implies 2x-x = 20 +10\\\\\implies x =30[/tex]
Hence, present age of the Victor as per given condition of the equation formed is equals to [tex]30[/tex] years.

Identify the area of the polygon that has vertices T(−3,1), S(−5,−4), A(−8,1), and N(−4,5)
Answer:
22.5
Step-by-step explanation:
The area of the polygon ABCD is 3/2 square units.
What is polygon?"It is two dimensional geometric figure having finite sides and vertices." A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
here, we have,
we know that,
formula to find the area of the polygon:
"If polygon having vertices (x1, y1), ....(xn,yn) then the area of the polygon is,
A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (xny1 - ynx1)
This formula is also known as shoelace formula."
For given example,
the polygon has vertices T(−3,1), S(−5,−4), A(−8,1), and N(−4,5)
Consider given vertices of polygon as,
(x1, y1) = (−3,1)
(x2, y2)=(−5,−4)
(x3, y3)=(−8,1)
(x4, y4)=(−4,5)
Using the formula of area of the polygon the area of the polygon ABCD would be,
A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (x4y1 - y4x1)
so, solving we get,
A = 1/2 | 17 + 27 - 36 -11|
A = 3/2
Therefore, the area of the polygon ABCD is 3/2 square units.

Step-by-step explanation:
i just used multiplication
Answer:
15 students
Step-by-step explanation:

So is 3 is 1/5 you multiply 3 by 5 (since 1/5 is 3 and to find 5/5 its you need a full 5/5)
3*5 = 15
Write the equation of the line, in slope-intercept form, through the
following two points:
(-14, 17)
(-10, 41)
Answer:
y=6*x+101
Step-by-step explanation:
Slope intercept form is y=mx+n, where m is the slope and n is the intercept.
Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.
I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.
Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.
To express the final equation we just plug in the values of m and n in the expression y=mx+n!
Answer:
y=6*x+101
Step-by-step explanation:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

Solve 3x^2+4=436
Please solve step by step
Answer:12
Step-by-step explanation:
Your goal with variables should always be to isolate them.
so the first step is to subtract the 4
3x^2+4=436
-4= -4
3x^2=432
The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.
3x^2=432
/3. =/3
x^2=144
the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.
square root of x^2=x
square root of 144=12
x=12
