Answer:
y - 25 = 4
Step-by-step explanation:
i’m guessing you meant this as “25 less than a number = 4.” so i can put tha as an expression.
Basically you’re gonna want to take the unknown number and turn it into a variable.
You should know what a variable is but if not it’s just a letter in place for an unknown number.
so since the unknown number, we will use the letter y as the variable.
so y-25=4
boom that’s it.
since there’s an unknown number in place of the bigger number, we can just put the variable and write the rest out as a regular problem.
and if you need to know the variable number it’s 29.

Convert the equation 9x + y = 4 Into slope-intercept form. Make sure to simplify if possible.
Answer:
x = -1/9y + 4/9
Step-by-step explanation:
9x+y=4
Step 1: Add -y to both sides.
9x+y+−y=4+−y
9x=−y+4
The required equation in slope intercept form is given by y = -9x + 4.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
here,
The slope intercept of the line is given as,
y = mx + c,
Where m = slope of the line and c = y-intercept of the line,
Given equation of line 9x + y = 4
Rearrange the equation,
9x + y = 4
y = -9x + 4
Thus, the required equation in slope intercept form is given by y = -9x + 4.

"Y varies directly as x". If y = 3 when x = 24, find y when x = 10.
Answer:
24=10
Step-by-step explanation:
The value of y when x = 10 is 5/4
If y varies directly as x, this is expressed as:
[tex]y \alpha x\\y = kx\\[/tex]
where
k is the constant of proportionality
If y = 3 when x = 24, then:
3 = 24k
k = 3/24
k = 1/8
In order to get the value of x when y = 10
Recall that y = kx
y = 1/8 * 10
x = 10/8
y = 5/4
Hence the value of y when x = 10 is 5/4

Answer:
[tex]x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Step-by-step explanation:
Given;
x² - 2x - 1 = 0
Solve by completing the square method;
⇒ take the constant to the right hand side of the equation.
x² - 2x = 1
⇒ take half of coefficient of x = ¹/₂ x -2 = -1
⇒ square half of coefficient of x and add it to the both sides of the equation
[tex]x^2 + (-1)^2 = 1 + (-1)^2[/tex]
[tex](x-1)^2 = 1 + 1\\\\(x-1)^2 = 2\\\\[/tex]
⇒ take the square root of both sides;
[tex]x-1 = +/- \ \ \sqrt{2} \\\\x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Therefore, option B is the right solution.

An employee at a company that assembles chandeliers is packing boxes
for shipping. In the first box, he packed 3 small chandeliers and 4 large
chandeliers, which weighed a total of 122 kilograms. In the second box,
he packed 3 small chandeliers and 2 large chandeliers, which had a
weight of 76 kilograms. Assuming the weight of the box isn't included in
the shipping weight, how much does each size of chandelier weigh? *
Answer:
Each Large chandelier weighs 23 kilograms (fat chandelier) and each small chandelier weighs 10 kilograms.
Step-by-step explanation:
I found this by subtracting the 122 from the 76 which gave me a 46 difference I then divided it by 2 since they took away 2 large chandeliers which gave me 23. I then multiplied 23 by 4 which gave me 92 and I saw that to get to 122 I would need 30 kilograms so I divided the 30 by the 3 small chandeliers.

This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
