4. Find the value of x in the given parallelogram.
(2x+5)*
1159
Your answer
Answer:
x = 55
Step-by-step explanation:
Use the property of a parallelogram,
" Opposite interior angles of a parallelogram are equal in measure"
By this property, opposite angles given in the figure will be equal.
(2x + 5)° = 115°
2x = 115 - 5
2x = 110
x = [tex]\frac{110}{2}[/tex]
x = 55
Therefore, x = 55 will be the value.

9z - 6+ 7z = 16z - 6
Answer:
z = z
Step-by-step explanation:
first you should combine like terms on the left side of the equation
9z + 7z = 16z
now rewrite
16z-6 = 16z-6
add 6 to both sides
16z = 16z
divide both sides by 16
z = z
Answer:
Both sides are equal. z has no solution. The input is an identity. It is true for all values.
Step-by-step explanation:
9z - 6 + 7z = 16z - 6
16z - 6 = 16z - 6
Both sides are equal. z has no solution. The input is an identity. It is true for all values.

find the value of x and y
The quantities x and y are positive. If x is
decreased by 20 percent and y is increased by
20 percent, then the product of x and y is
Answer:
Positive
Step-by-step explanation:
Two negative numbers, no matter how small or large are always positive when multiplied. Same goes for two positive numbers. If it was positive beforehand that means both numbers were either negative or positive. A percentage of a negative number is still negative and a percentage of a positive number is still positive so the answer won't change.

El punto p se muestra en la recta numerica.
La distancia entre el punto Q y el punto P es de 6 1/2 unidades . Que numero podria representar el punto Q ?
Answer:
2 1/2 o 10 1/2
Step-by-step explanation:
q podría estar 6.5 unidades a la derecha ... oa la izquierda ... del punto p.
a la derecha: p + q ⇒ -4 + (6 1/2) = 2 1/2
a la izquierda: p - q ⇒ -4 -(6 1/2) = -10 1/2

y=x+3
y=1/3x-5
solve and graph
Answer:
(-9, -12)
Step-by-step explanation:
Given the expressions
y=x+3
y=1/3x-5
Equating both expressions;
y = y
x + 3 = 1/3x - 5
x - 1/3x = -5 -3
2/3 x = -8
x/3 = -4
x = -12
Since
y = x+ 3
y = -12 + 3
x = -9
Hence the required solution is (-9, -12)
The vertices of triangle PQR are given in the standard (x,y) coordinate plane below. What is the area, in the square coordinate units, of triangle PQR?
Answer:
Area = 12
Step-by-step explanation:
Given
See attachment
Required
Area of [tex]\triangle PQR[/tex]
From the attached image, we have:
[tex]P = (6,10)[/tex]
[tex]Q = (10,8)[/tex]
[tex]R = (6,4)[/tex]
The area is then calculated as:
[tex]A = \frac{1}{2}|(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y1 - x1y3)|[/tex]
So, we have:
[tex]A = \frac{1}{2}|(6*8 - 10*10) + (10*4 - 6*8) + (6*10 - 6*4)|[/tex]
Using a calculator:
[tex]A = \frac{1}{2}|-24|[/tex]
Remove absolute bracket
[tex]A = \frac{1}{2} * 24[/tex]
[tex]A = 12[/tex]
The graph shows the line y= -3x - 6.
Complete the table so it includes two solutions to the equation.
Answer:
0 | -6
____
3 | -15
Step-by-step explanation:
just plug in the numbers they give u in the chart
when x = 0 -> y = -3*0-6 = -6
when y = -15 -> -15 = -3x-6 -> x = 3
The graph of the line y = -3x -6 is giving the solution (0,-6) and (3,-15).
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
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 equation of the line is y = -3x - 6. the two points on the graph are satisfying the equation.
x = 0 , y = -3 x 0-6 = -6
y = -15 -> -15 = -3 x-6 -> x = 3
Therefore, the graph of the line y = -3x -6 is giving the solution (0,-6) and (3,-15).

An exponential function is given by the equation y=3x. Using the points xx and x+1x+1, show that the y-values increase by a factor of 3 between any two points separated by x2−x1=1.(4 points)
Answer:
Here we have the function:
y = f(x) = 3^x
Using the values:
x and (x + 1)
We need to find that the y-value increases by a factor of 3.
So we need to prove that:
f(x + 1) = 3*f(x).
Or we can see the quotient:
f(x + 1)/f(x) = 3
Here we can find the values:
f(x + 1) = y = 3^(x + 1)
f(x) = y' = 3^x
If we take the quotient, we get:
[tex]\frac{f(x + 1)}{f(x)} = \frac{3^{x + 1}}{3^x}[/tex]
Here we can use the properties:
[tex]a^n*a^m = a^{n + m}[/tex]
[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]
Using these in the quotient equation we get:
[tex]\frac{f(x + 1)}{f(x)} = \frac{3^{x + 1}}{3^x} = \frac{3^x*3^1}{3^x} = \frac{3^x}{3^x}*3 = 1*3 = 3[/tex]
Then:
[tex]\frac{f(x + 1)}{f(x)} = 3[/tex]
[tex]f(x + 1) = 3*f(x)[/tex]
So we found that the y-value increases by a factor of 3 between any two points x₂ and x₁ such that: x₂ - x₁ = 1.
Find the area of the Regular Octagon below and show all mathematical reasoning.
9514 1404 393
Answer:
200√2 square units
Step-by-step explanation:
The area of a regular polygon with n sides and radius r is given by the formula ...
A = (n/2)r²·sin(360°/n)
Here, we have n=8 and r=10, so the area is ...
A = (8/2)(10²)sin(360°/8) = 4·100·√2/2
A = 200√2 . . . square units
if the HCF of 408 and 1032 is expressible in the form of 1032 into 2 + 408 into P then find the value of p
Answer:
below.
Step-by-step explanation:
408 = 2*2*2*3*17
1032 = 2*2*2*3*43
So the HCF is 2*2*2*3 = 24
24 = 2/1032 + p/408
24 - 2/1032 = p/408
p = (24 - 2/1032) * 408
p = 9791.21 to nearest hundredth.
