Answer:
x = -17/2
Step-by-step explanation:
2(x+13)=9
2x+26=9 (multiplying 2 with both the numbers)
2x=9-26 (shifting 26 on the other side of the equation changes its sign)
2x=-17
x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)
Answer:
2 x x + 2x13=8
or,2x+26=9
or,2x=9-26
or,2x= -17
or,x= -17/2
so, x= -8.5

Answer:
35/16 2 2/16
Step-by-step explanation:
1 1/4 = 5/4
1 3/4 = 7/4
5 * 7 = 35
4 * 4 = 16

2 3/16
Step-by-step explanation:
First, we have to convert our mixed numbers to improper fractions, so our new equation is:
5/4 x 7/4 = 35/16
35/16 = 2 3/16

Answer:
-41/20
Step-by-step explanation:
Hi there!
From the question, I believe you’re asking [tex]\frac{3}{4}[/tex] - [tex]2 \frac{4}{5}[/tex]
First, put the whole number 2 back into the fraction to create an improper fraction.
This would become [tex]\frac{14}{5}[/tex]. Now, we have to find a common denominator between the two fractions. Both 4 and 5 can go into 20, so that will be our common denominator. To turn [tex]\frac{3}{4}[/tex] into a fraction with a denominator of 20, we have to multiply both the numerator and denominator by 5. [tex]\frac{3}{4}[/tex] becomes [tex]\frac{15}{20}[/tex]. We do the same thing for [tex]\frac{14}{5}[/tex] except we multiply the numerator and denominator by 4. We end up with [tex]\frac{56}{20}[/tex]. Now we just have to subtract!
[tex]\frac{15}{20} - \frac{56}{20}[/tex] leaves us with [tex]- \frac{41}{20}[/tex] , which can’t be simplified any further.
Given: LMNK is a parallelogram.
Find x.
N
12x - 2
K
M
22
L X= ?
Answer:
The value of x is 2
Step-by-step explanation:
In the parallelogram, every two opposite sides are equal in lengthsLet us solve the question
In the given figure
∵ LMNK is a parallelogram
∵ ML and NK are opposite sides
→ By using the rule above
∴ ML = NK
∵ ML = 22
∵ NK = 12x - 2
→ Equate them
∴ 12x - 2 = 22
→ Add 2 to both sides
∵ 12x - 2 + 2 = 22 + 2
∴ 12x = 24
→ Divide both sides by 12
∴ x = 2

I have the inequality 120A + 100B <= 220 how do i graph this?
Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
Answer:
See below
Step-by-step explanation:
Given inequality
120a + 100b ≤ 220This is a linear inequality, to graph first find intercepts:
a- intercept, when b = 0
120a = 220a = 220/120 = 1.833b- intercept, when a = 0
100b = 220b = 220/100 = 2.2We got two points:
(1.833, 0) and (0, 2.2)Now graph this with following steps
1. Plot these points on the coordinate plane. 2. Construct a solid line passing through those two points. (it would be dotted line is inequality sigh was > or < )3. Shade the area left to the line. (it would be the area to right if inequality sign was ≥)The graph is attached

What does the 180 mean in this (n-2)180 and why do we multiply it
Answer:
Polygons can be separated into triangles by drawing all the diagonals that can be drawn from one single vertex. If you look back at the formula, you'll see that n – 2 gives the number of triangles in the polygon, and that number is multiplied by 180, the sum of the measures of all the interior angles in a triangle.

A quadratic function is defined by
g(x) = (x + 4)2 + 7
1. What is the vertex of the graph of function g?
2. Does the vertex represent the minimum value or the maximum value of the function?
Explain or show how you know.
3. If you were to shift this graph 6 units down from where it is now, what would be the equation represented by the new graph?
Answer:
1. The vertex of the graph of the function is (-4, 7)
2. The vertex represents a minimum value
3. The equation represented by the new graph is g(x) = (x + 4)² + 1
Step-by-step explanation:
The given quadratic function is given in vertex form, y = a·(x - h)² + k, as follows;
g(x) = (x + 4)² + 7
1. By comparing the given quadratic function and the vertex form of a quadratic equation, we have;
a = 1, h = -4, and k = 7
The vertex of the graph of the function, (h, k) = (-4, 7)
2. Given that a = 1 > 0, the graph of the quadratic function opens upwards and the vertex represents a minimum value
3. Shifting the graph 6 units down from where it is now will give;
The vertex = (h, k - 6) = (-4, 7 - 6) = (-4, 1)
h = -b/(2·a), k = (-b²/(4·a) + c = -a·h² + c
c = k + a·h²
Therefore, initial value of the constant term, c = -1×(-4)² + 7 = 23
After the shifting the graph 6 units down, c = 23 - 6 = 17
∴ k = 1 = -a·(-4)² + 17
∴ -16/16 = -1 = -a
a = 1
Therefore, the equation represented by the new graph is g(x) = (x + 4)² + 1.
1. The vertex of the graph of the function is (-4, 7)
2. The vertex represents a minimum value
3. The equation represented by the new graph is g(x) = (x + 4)² + 1
What is a graph?
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given quadratic function is given in vertex form, y = a·(x - h)² + k, as follows;
g(x) = ( x + 4 )² + 7
1. By comparing the given quadratic function and the vertex form of a quadratic equation, we have;
a = 1, h = -4, and k = 7
The vertex of the graph of the function, (h, k) = (-4, 7)
2. Given that a = 1 > 0, the graph of the quadratic function opens upwards and the vertex represents a minimum value
3. Shifting the graph 6 units down from where it is now will give;
The vertex = (h, k - 6) = (-4, 7 - 6) = (-4, 1)
h = -b/(2·a), k = (-b²/(4·a) + c = -a·h² + c
c = k + a·h²
Therefore, initial value of the constant term, c = -1×(-4)² + 7 = 23
After the shifting the graph 6 units down, c = 23 - 6 = 17
∴ k = 1 = -a·(-4)² + 17
∴ -16/16 = -1 = -a
a = 1
Therefore, the equation represented by the new graph is g(x) = (x + 4)² + 1.
