solve 2x + 5y = -1for y. Then find the value of y when x=-2
solve 2xy - x = 3for y. Then find the value for y when x=2
In equation (1) the value of y = 3/5 and In equation (2) the value of y = 5/4
In the given statement is
Solve 2x + 5y = -1 for y.
To find the value of y when x= -2
Now, Equation is 2x + 5y = -1 …..(1)
Put the value of x = -2 in eq. 1
2 (-2) + 5y = -1
-4 + 5y = -1
5y = -1 + 4
y = 3/5
Again, Solve 2xy - x = 3 for y
To find the value of y when x = 2
Now, Equation is : 2xy - x = 3 ….(2)
Put the value of x = 2 in eq. (2)
2(2)y - 2 = 3
4y - 2 = 3
4y = 5

Let f ( x ) = 1 x and g ( x ) = x 2 + 5 x . a. Find (f · g)(x). b. Find the domain and range of (f · g)(x).
The answer to all the subparts are given:
(f · g)(x) = [(f X g)(x) = x + 5]The domain of the given function: (-∞, 0) ∪ (0, ∞)The Range of the given function: (-6.25, 0) ∪ (0, ∞)(A) (f · g)(x):
So,
(f×g)(x)=f(x)*g(x)Plug in:
[tex](f X g)(x)=\frac{1}{x}\left(x^2+5 x\right)[/tex]Simplify as follows:
[tex]\begin{aligned}&(f X g)(x)=\frac{1}{x}(x(x+5)) \\&(f X g)(x)=x+5\end{aligned}[/tex]
(B) Domain:

Then we can look for a common domain.
The domain of f(x):
[tex]f(x)=\frac{1}{x}[/tex]At x=0, we know that f(x) is undefined.
As a result, the domain will be:

If g+9=4 and h-8--3, what is the
value of g + h?
Answer:
g + h = 6
Step-by-step explanation:
We are told that:
• [tex]g + 9 = 4[/tex]
• [tex]h- 8=3[/tex].
To calculate the value of g + h, we have to rearrange the above equations to make g and h their respective subjects:
• [tex]g + 9 = 4[/tex]
⇒ [tex]g + 9 - 9 = 4 - 9[/tex] [Subtracting 9 from both sides]
⇒ [tex]g = \bf -5[/tex]
• [tex]h- 8=3[/tex]
⇒ [tex]h - 8 + 8 = 3 + 8[/tex] [Adding 8 to both sides]
⇒ [tex]h = \bf 11[/tex]
Now that we know the values of g and h, we can find the value of g + h:
[tex]g + h[/tex]
[tex]= -5 + 11[/tex]
[tex]= \bf 6[/tex]
Therefore the value of g + h is 6.

Write an equation of a parabola with the given information.
vertex (0,0) , focus (0, 1/2)
The equation that defines the parabola with vertex at the point and focus at (0, 1/2) is
y = 2x²
What is a parabola?The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.
The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.
In this case we have the vertex of the parabola at the point (0,0) and the focus at the point (0, 1/2) this is displaced on the y-axis upward, so the parabola is of the form.
y = x²
Canonical equation
(y - yo) = 4p(x - xo)
Vertex (0, 0)xo, yo = (0 , 0)
Focus:

rate in miles per hour if there are 5,280 feet in a mile?
Which girl bikes faster?
Nina's rate in miles per hour is 12.711 and Nina bikes faster than Sophia.
Nina's speed can also be defined as her Average Speed.
Similarly, Sophias's speed can also be defined as her Average Speed.
We have Sophia's speed = 10 miles in hour = 10 miles per hour
What is average speed and average?
Average speed is the total distance travelled by an object to the total time taken. means,
[tex]Average Speed = \frac{Total Distance}{Total Time }\\[/tex]
Total Distance covered by Nina = 63,360ft.
[tex]1 \ mile = 5280 \ feet\\[/tex]
So,Nina's Distance (in miles) [tex]\frac{63360}{5280}= 12 \ miles[/tex]

evaluate the expression 13 divided by (2.5 - |-3 1/8|) times 3 to the third power
Answer: -561.6
Step-by-step explanation:
First, recall PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)
In the equation, we need to work through (2.5 - |-3 1/8|) first.
The absolute value of |-3 1/8| is 3 1/8
We change 3 1/8 to a decimal
3 1/8 = 3.125
Now Subtract (2.5 - 3.125)
This equals -0.625
Next, divide 13 by -0.625
13 ÷ -0.625 = -20.8
Then, multiply -20.8 by 3³
3³ = 27
So -20.8 × 27 = -561.6

Area of triangle A is 72.2 cm square.
Here, we are given that triangles A and B, as shown in the figure are congruent to each other.
They are also both right angle triangles.
The length of the hypotenuse of A is 17cm
and the height of triangle be = 12cm
But as these two are congruent,
height of triangle A will also be 12cm.
Now, according to Pythagoras theorem,
[tex]hypotenuse^{2} = base^{2} +height^{2}[/tex]
[tex]17^{2}[/tex] = [tex]12^{2}[/tex] + [tex]base^{2}[/tex]

Thus, the area of the triangles = 1/2 * base height

Thus the area of triangle A will be 72.2 cm square.

The decimal point should be moved two places to the right.
The number we have given is = 6.8
We have to find how many decimal point should be moved when 6.8 is multiplied by 100
We know that when we multiply a decimal number with 10, 100, 1000,…. and so on. We shift the decimal point to the right side according to the number of zeroes present.
According to the question, we have two zeroes therefore we will shift the decimal point to the rights side two times, that is,
6.8 * 100 = 680
