party she plans and $100 for every wedding she plans. Her goal every summer is to make
$1000 to put towards college. Write an equation that represents the number of parties (x) and
the number of weddings (y) that Vanessa could plan during the summer in order to meet her
$1000 goal:
The required equation for the given condition is 50x + 100y = 1000.
What is an algebraic expression?
An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression (addition, subtraction, multiplication, division, and exponentiation by an exponent that is a rational number).
Given, the charge for every birthday party =$50
number of birthday parties = x
So, the total charge for birthday parties = 50x
the charge for every wedding = $100
the number of weddings = y
So, the total charge for the wedding = 100y
Then,
Total amount achieve = $1000
or, 50x + 100y = 1000
Hence, the required equation is 50x + 100y = 1000.

answer:
x = 18, 60.
step-by-step explanation:
evaulating (3x+6) = (4x-12) and solving for x gives us x = 18. you didn't include the angle, so i can't give you that. but

you have 600 ft of fencing to make a pen for hogs. if you have a river on one side of your property, what are the dimensions (in ft) of the rectangular pen that maximize the area?
The dimensions that maximize the area are 150ft × 300ft.
What do we mean by dimensions?A topological measurement of an object's dimension is the extent of its covering qualities. It is, essentially, the number of coordinates required to specify a location on the object. A cube is three-dimensional, whereas a rectangle is two-dimensional.So, let y be the length of the side parallel to the river and x be the length of each of the two sides perpendicular to it.
The following provides the total fencing length:
2x + y = 600y = 600 - 2xThe rectangular pen's surface area is:
A = xyA = x(600 - 2x)A = 600x - 2x²We may determine the value of x required to maximize the area by determining the value of x for which the derivative of the area function is zero:
dA(x)/dx = d(600x - 2x²)/dx0 = 600 - 4xx = 150The value of y is: for x=150
y = 600 - 2x = 600 - (2 × 150)y = 300Therefore, the dimensions that maximize the area are 150ft × 300ft.

The red throated loon dived down to a distance of 12 feet under the water in 8 seconds.
We can assume that the loon is diving at a constant rate.
The relation between the elevation wise of the loan after 1 second into the dive can be represented by the linear equation which has the slope,
Slope = 12/8
Slope = 3/2
Now as we have the slope of the equation we can write the equation by using the point slope form, with the point, (8,12)
(y - 12)/(x - 8) = 3/2
2y - 24 = 3x - 24
3x - 2y = 0
This is the equation that represent the elevation y of the loan after x seconds.
When the elevation of The Loon is 22 feet,
We can put y = 22,
3x = 2(22)
x = 14.67 seconds.
So, the loon has been diving for 14.67 seconds.

What is the solution to the following equation?
x² + 3x + 7 = 0
A. x= 3+-√25/2
B. x= -3+-√37/2
C. x= -3+-√²7/2
D. x= -3+-√-19/2
Answer: D
Step-by-step explanation:
Answer: Choice D
[tex]x = \frac{-3\pm\sqrt{-19}}{2}\\\\[/tex]
==================================================
Explanation:
Compare the given equation x² + 3x + 7 = 0 to ax² + bx + c = 0 to find that,
a = 1b = 3c = 7Those values are plugged into the quadratic formula to get the following:
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-3\pm\sqrt{(3)^2-4(1)(7)}}{2(1)}\\\\x = \frac{-3\pm\sqrt{-19}}{2}\\\\[/tex]
which points us to choice D being the final answer.

Side note:
The discriminant [tex]d = b^2 - 4ac = (3)^2-4(1)(7) = -19[/tex] is negative, so there are no real solutions. Instead, the two solutions are non-real complex numbers.

The equation of the given line written in the slope-intercept form is: y = 21x + 10.25.
What is a slope?
The slope or gradient of a line in mathematics is a quantity that specifies both the direction and the steepness of the line.
Note that the general slope equation is:
y = mx + b
Where
m is the slope of the line and
b is the y-intercept.
In this specific instance, m is the change in the price of the ticket
b is the additional fee value that needs to be included for each ticket
Hence, the cost of the ticket (y) is given as:
y = (change rate of x) + added fee to every order
Where rate of change = 21; and
The fee added to each order is 10.25
Given the above, the general equation becomes:
y = 21x + 10.25
