solve for x 2/3x + 9 = - 13
Answer:
X=-33
Step-by-step explanation:
Answer:
x= -33
Step-by-step explanation:
Subtract 9 from both sides:
2/3x+9-9=-13-9
Simplify the arithmetic:
2/3 · x =-13-9
Simplify the arithmetic:
2/3 · x = -22
Multiply both sides by inverse fraction 3/2:
2/3x ·3/2= -22 ·3/2
Group like terms:
2/3 ·3/2x= -22 ·3/2
Simplify the fraction:
x=-22 · 2/3
Multiply the fractions:
x= -22·2/3 ÷2
Simplify the arithmetic:
x = -33

The perimeter of a rectangle is 50 cm, the length is 10 cm. What is the width? Area?
Width=
area=
Answer:
Width: 15 cm
Area: 150 cm squared
Step-by-step explanation:
I did 10 + 10 to get the total of the two sides of the rectangle.
I subtracted 20 from 50 to get what the two widths are supposed to add up to.
The answer was 30 so I divided 30 by 2 to get what one width equals.
The width equals 15.
To get the area of a rectangle you have to multiply the length by the width which would be 150 cm squared.
Step-by-step explanation: the width is 15cm
Write the equation 12y = 4x + 1 in standard form.
Answer:
4x - 12y = -1
Step-by-step explanation:
Standard form Ax +By = C
12y = 4x + 1
0 = 4x - 12y +1 Substract 12y from both sides
-1 = 4x - 12y as 4x - 12y = -1 Substract -1 from both sides

what is –0.025 as a fraction??
Answer:
- 1/40
Step-by-step explanation:
-0.025 = -0.025/1
we have 3 numbers after the decimal point so we multiply both numerator and denominator by 1000
( -0.025 x 1000)/(1 x 1000) = -25/1000
reduce the above fraction by dividing both numerator and denominator by the greatest common divisor between them. in this case GCD (25,1000) = 25.
(-25/25)/(1000/25) = - 1/40

write a linear function f with the given values
(The top one please)
Answer:
y=-6.
Step-by-step explanation:
1) the condition f(-1)=-6 and f(4)=-6 mean points A and B have coordinates (-1;-6) and (4;-6);
2) the points A and B has the same y-coordinate, it means, the required line is parallel to the x-axis and the required function is: y=-6.
P.S. the suggested way is not the only one.
The linear function f is f(x) = -6.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(-1) = -6
f(4) = -6
The linear function f can be in the form of f(x) = mx + c.
Now,
m = (-6 + 6) / (4 - 1)
m = 0/3
m = 0
Now,
f(-1) = -6
x = -1
f(x) = mx + c
f(-1) = 0 x -1 + c
-6 = 0 + c
c = -6
Now,
f(x) = -6
Thus,
The function f is a constant function.
f(x) = -6

The construction of copying is started below. The next step is to set the width of the compass to the length of. How does this step ensure that the new angle will be congruent to the original angle?
How is copying a line segment similar to copying an angle?
1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.
What is geometry ?
Geometry is the branch of mathematics focused on the relationships and characteristics of solids, surfaces, solids, and other such objects.
Given, we must describe the first stage , which will be the process of copying a line segment, which ensures that the new line segment is the same length as the original line segment. An angle and a segment must be copied as a first step. The picture gives a description of the copying construction.
The width of the compass must then be adjusted to the segment length. The new angle will now be consistent with the original angle. This is the next step.
Making a perpendicular line is the next step. Here, it is demonstrated how to draw a line through a point that is perpendicular to the given line.
Therefore , 1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.

6x^3y + 12x^2y^2 - 15x^3y^3
Please help me solve for x in
Inx + In(x +25)=0
Step-by-step explanation:
ln(x) + ln(x + 25) = 0
ln(x(x + 25)) = 0
ln(x² + 25x) = 0
ln(x² + 25x) = ln(1) , x ≥ 0
x² + 25x = 1
x² + 25x + 625/4 = 1 + 625/4
(x + 25/2)² = 629/4
x + 25/2 = ±√(629/4)
x = ( -25 ±√629)/2
x = (-25 - √629)/2 atau ( -25 + √629)/2

8. GARDEN A rectangular garden is 12 feet across and 16 feet long. It is
surrounded by a border of mulch that is a uniform width, x. The
maximum area for the garden, plus border, is 285 ft.
a. Write a polynomial equation to represent the situation.
12 it
b. Write and solve a system of equations.
c. What are the dimensions of the garden plus border?
The dimensions of the border is 1.5 feet for the garden
A rectangle is a quadrilateral with four sides and four angles in which opposite sides are equal and parallel.
The area of a rectangle = Length * breadth
Given that length of garden = 16 ft., width of garden = 12 ft.
It is surrounded by a mulch of width x, hence:
New length = 16 + x + x = 16 + 2x
New width = 12 + x + x = 12 + 2x
The area of garden = 16 + 2x(12 + 2x) = 192 + 56x + 4x²
Since the maximum area is 285 ft, hence:
192 + 56x + 4x² = 285
4x² + 56x - 93 = 0
x = 1.5 feet
The dimensions of the border is 1.5 feet

graph the equation y=5x
Answer:
Make a line connecting points (0,0) (1,5) and (-1,-5)
Step-by-step explanation:
Okay, so you have to start your first point at (0,0), which is the origin, because there is no y-intercept in the equation.
Next you use slope, Rise/Run to plot your next point. In the equation y=mx+b, the slope is in m. So in y=5x, the slope is 5/1 .
So, you're going to move up 5 from the origin and move to the right once, which will give you the point (1,5).
If you need another point to make a line go the opposite way from the origin. So we would go down 5 and left 1. That would give us the point (-1,-5)
