Answer:
Refer to the attachmentThe value of angle is 40 degrees
The value of angle P is 140 degrees
Properties of a ParallelogramThe opposite angles of a parallelogram are equal. The opposite sides of a parallelogram are equalThe sum of angle in a parallelogram is 360 degree
Therefore,
∠S = x + 15
∠p = 6x - 10
2(x + 15) + 2(6x - 10) = 360
2x + 30 + 12x - 20 = 360
14x + 10 = 360
14x = 350
x = 350 / 14
x = 25 degrees
∠S = x + 15 = 25 + 15 = 40 degrees
∠p = 6x - 10 = 6(25) - 10 = 150 - 10 = 140 degrees

The segments AC, CB, and AB can form a triangle, and the statement is true.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given that AC=9 cm, CB= 8cm and AB=15cm
The segments AC, CB, and AB satisfy the triangle inequality, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
AC + CB = 9cm + 8cm = 17cm, which is greater than AB = 15cm.
Similarly, AC + AB = 9cm + 15cm = 24cm, which is greater than CB = 8cm. CB + AB = 8cm + 15cm = 23cm, which is also greater than AC = 9cm.
Therefore, the segments AC, CB, and AB can form a triangle, and the statement is true.

Let f(x)=x2 2x 3. What is the average rate of change for the quadratic function from x=−2 to x = 5? Enter your answer in the box.
The average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.
What is Slope?A slope is also known as the gradient of a line or the average rate of change of a number that helps to know both the direction and the steepness of the line.
The rate of change of any function is the slope of the function, therefore, the slope of the function is written as,
[tex]m = \dfrac{y_2 - y_1}{x_2-x_1}[/tex]
As the value of the y is the function of the x, while the value of x is given, therefore,
[tex]x_2 = 5\\x_1=-2\\\\[/tex]
Now, the value of y,
[tex]y_2 = f(5) = x^2 +2x+3 = (5)^2+2(5)+3 = 38\\y_1 = f(-2) = x^2 +2x+3 = (-2)^2+2(-2)+3 = 3[/tex]
Substituting the value of x and y in the formula of the slope, we can write the slope as,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{f(x=5) - f(x=-2)}{5-(-2)}\\\\m = \dfrac{38-3}{7}\\\\m= 5[/tex]
Hence, the average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

Find the value of x.
Answer:
155°
Step-by-step explanation:
The obtuse angle of the large (outside) triangle is the supplement of 60°, so is ...
180° -60° = 120°
The angle x is the sum of the remote interior angles of that large triangle:
x = 35° +120° = 155°
__
Check
The other acute angle in the smaller (left) right triangle is 90° -35° = 55°. Then the top acute angle in the larger (bottom, right) right triangle is ...
180° -55° -60° = 65°
The other acute angle in that triangle is 90° -65° = 25°. It is supplementary to angle x. Hence angle x is 180° -25° = 155°, as above. (Note that x is also the sum of 90° and 65°, the remote interior angles of the nearest right triangle to x.)
what is 20/16=d/12? what equals d?
Answer:
d = 15
Step-by-step explanation:
Divide the numbers
[tex]\frac{20}{16} =\frac{d}{12}[/tex]
[tex]\frac{5}{4} =\frac{d}{12}[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]12*\frac{5}{4} =12*\frac{d}{12}[/tex]
Cancel multiplied terms that are in the denominator
[tex]12*\frac{5}{4} =d[/tex]
Multiply the numbers
[tex]15=d[/tex]
Move the variable to the left
[tex]d=15[/tex]
Hence, d= 15.

. What are the coordinates of the point (-1,0) after a translation 5 units to the right?
The coordinates of the point (-1,0) after a translation 5 units to the right?
To get the coordinates of the point 1,0 after a translation 5 units to the right
The point's x-coordinate will rise by 5 units after being moved 5 units to the right, while the y-coordinate stays the same.
The starting point was at (-1, 0).
Increasing the x-coordinate by 5 units:
x-coordinate changed: -1 + 5 = 4.
Therefore, after being moved 5 units to the right, the point's new coordinates are (4, 0).

Solve the system of equations by the substitution method.
x+11y=51 3x+5y=13
Answer:
(-4, 5)
Step-by-step explanation:
Hi there!
We are given the following system:
x+11y=51
3x+5y=13
And we want to solve it by substitution.
When we solve a system by substitution, we want to solve one of the equations for a variable; the variable should equal an expression containing the other variable. Then, we substitute that expression into the other equation as the variable we solve for, solve for that variable, and then use the value of the solve variable to find the value of the first variable
It's easier to solve for a variable if the leading coefficient in front of that variable is 1, like with x in the first equation (x+11y=51)
To solve this equation for x, we can subtract 11y from both sides.
x+11y=51
-11y -11y
_____________
x=51-11y
Now substitute 51-11y as x in 3x+5y=13:
3(51-11y)+5y=13
Multiply
153-33y+5y=13
Combine like terms.
153-28y=13
Subtract 153 from both sides
-28y=-140
Divide both sides by 28
y=5
Now substitute 5 as y in 51-11y to solve for x.
x=51-11y
x=51-11(5)
multiply
x=51-55
Subtract
x=-4
The answer is x=-4, y=5, or as a point, (-4, 5)

Find the value of log 1 2 462 to four decimal places.
The value of logarithm function log₀.₅ 462 around the four decimal places is -8.8517.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The expression is [tex]\rm log _{\frac{1}{2}} 462[/tex].
We know the formula of a logarithm.
[tex]\rm log_ab = \dfrac{log\ b}{log\ a}[/tex]
Then we have
[tex]\rm log _{\frac{1}{2}} 462 = \dfrac{log\ 462}{log\ \frac{1}{2}}\\\\\\log _{\frac{1}{2}} 462 = \DFRAC{2.66464}{-0.3010299}\\\\log _{\frac{1}{2}} 462 = -8.852[/tex]

find all values of x for which the perimeter is at most 32
Answer:
0 < x ≤ 11
Step-by-step explanation:
perimeter = (x - 6) + (x - 6) + x + x
⇒ perimeter = 4x - 12
If the perimeter is "at most 32" then
4x - 12 ≤ 32
⇒ 4x ≤ 44
⇒ x ≤ 11
Therefore, 0 < x ≤ 11
Ashley compares the fees charged by two babysitting agencies.The fees are shown below. Determine which function is described in the table below.Drag-and-drop either agency A or agency B into each box to correctly identify which function is described.

Agency A: y = 12x

To create a straight line equation for the data in table, use [tex]y = mx + b[/tex], where m is the slope and b is the y-intercept.
To find the slope m, take 2 points from the table and use the slope formula.
Let [tex](x_1,y_1)[/tex] = (3, 36)
Let [tex](x_2,y_2)[/tex] = (5, 60)
Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{60-36}{5-3}=12[/tex]
Now use the point-slope formula to create the final equation:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-36=12(x-3)[/tex]
[tex]\implies y=12x[/tex]
Therefore, Agency A pays a rate of $12 per hour.
Agency B
From inspection, the function is a straight line.
Therefore we can use the straight line equation [tex]y = mx + b[/tex],
where m is the slope and b is the y-intercept.
From inspection, we can see that the line crosses the y-axis at (0,20). Therefore, the y-intercept is 20.
[tex]\implies y=mx+20[/tex]
Taking 2 points on the line and using the slope formula to find the slope m:
Let [tex](x_1,y_1)[/tex] = (0, 20)
Let [tex](x_2,y_2)[/tex] = (3, 50)
Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{50-20}{3-0}=10[/tex]
Therefore, the final equation is: [tex]y=10x+20[/tex]
Therefore, Agency B pays an initial fee of $20 plus a rate of $10 per hour.

x=25.5
The required solution of the given equation is given as x = 25.5.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
x + 9.5 = 35
Subtract 9.5 from both sides.
