x=2 y=2
4xy^2-6
Answer:
→ 26
Step-by-step explanation:
Given that: x = 2, y = 2→ 4xy²-6
→ 4(2)(2)²-6
→ 8*4-6
→ 32-6
→ 26
Solution:
4xy² - 6x = 2y = 2Let's substitute the values to obtain our answer.
Solving the term "4xy² - 6"
4xy² - 6=> 4(x)(y²) - 6=> 4(2)(2²) - 6=> 4(2)(4) - 6=> 32 - 6=> 26Hoped this helped!

Which of the equations below could be the equation of this parabola?
A. y = 4x2
B. x = 4y2
C. X=-4x2
D. Y=-4x2
Answer:
D
Step-by-step explanation:
The graph opens downward so we would expect the integer to be negative. Also because the parabola opens downward you cannot have the equation be X=, this leaves Y=-4xsquared as the only viable option
Angle between 0 and 360 coterminal to 444 degrees
Answer:
444 is coterminal to 84
Step-by-step explanation:
Just subtract 360 from 444 and you have your answer
444 - 360 = 84
If - 20 is added to a number, the sum will be 8 times the number. Find the number.
...
I’m not understanding this equation
Let the number = x
add -20’tonx to have x + -20 which becomes x-20
That equals 8 times the number x
The equation becomes
X-20 = 8x
Subtract x from both sides :
-20 = 7x
Divide both sides by 7:
X = -20/7
The number is -20/7

The number of solutions the system of equation x - y = -2; y = (2x + 3) is one solution.
The correct answer option is option c
How to find number of solutions in a system of equationx - y = -2
y = (2x + 3)
Substitute equation (2) into (1)x - y = -2
x - (2x + 3) = -2
x - 2x - 3 = -2
-x = -2 + 3
-x = 1
x = -1
Substitute the value of x into equation (1)x - y = -2
-1 - y = -2
Add 1 to both sides-y = -2 + 1
-y = -1
divide both sides by the coefficient of -y which is -1y = -1/-1
y = 1
In conclusion, the equation x - y = -2; y = (2x + 3) has only one solution.

What is the value of Fraction 1 over 2x3 + 3.4y when x = 2 and y = 5? 80 points
Answer:
1/29 (≈ 0.0345 if you want it in decimals)
Step-by-step explanation:
[tex]\frac{1}{2x3+3.4y}[/tex] then plug in the numbers given
[tex]\frac{1}{2(2)3+3.4(5)}[/tex]then simplify
2(2)3=4*3=12
3.4(5)=17
1 over 12+17
1 over 29

A downtown parking lot charges $5 per hour for the fort 2 hours, then $2.50 per hour after that. Which equations describes the total cost y as a function of the hours x?
We will get the piecewise function:
y = f(x) = $5*x for 0 ≤ x ≤ 2y = f(x) = $10 + $2.50*(x - 2) for 2 < xHow to write the piecewise function?
We know that the parking lot charges $5 per hour for the first two hours, and then $2.50 per hour after that.
So the function behaves differently in different intervals of its domain, this will be a piecewise function. To write it, we just need to clarify how the function behaves in each part of the domain.
Here the function will be:
y = f(x) = $5*x for 0 ≤ x ≤ 2y = f(x) = $10 + $2.50*(x - 2) for 2 < xSo for the first two hours (x is the number of hours), the cost is $5, then for any hour after that, the cost will be the $10 for the first two hours plus $2.50 for each hour after that.
That is the piecewise function that describes the total cost y as a function of the number of hours, x.

Quadratic equation: [tex]y = ax^2 + bx + c[/tex]
The graph of a quadratic equation is a parabola. The value of [tex]a[/tex]determines its orientation.
If [tex]a>0[/tex] then the parabola opens upwards and its vertex is its minimum point.
If [tex]a<0[/tex] then the parabola opens downwards and its vertex is its maximum point.
Given:
f(x) = x²g(x) = x² + 2⇒ g(x) = f(x) + 2
So the transformation of f(x) to g(x) is an upward shift of 2 units, or
a translation of f(x) by the vector [tex]\left(\begin{array}{ccc}0\\2\end{array}\right)[/tex].
Therefore, the y-coordinate of the vertex of g(x) will be 2 units more than the y-coordinate of the vertex of f(x).
Therefore,
f(x) is a parabola that opens upwards with a vertex at (0, 0)g(x) s a parabola that opens upwards with a vertex at (0, 2)PLEASE HELP ME QUICKKK, FIRST CORRECT PERSON GETS BRAINLIEST
