13. What is the sum of the solutions of the 2 equations
below?
8x = 12
2y + 10 = 22
A. 23
B. 7
7 1 / 1
C. 9
D. 10
E. 173
Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5
2y+10=22
2y=12
y=6
1.5+6=7.5=7½
Answer:
7.5 or 7½
Step-by-step explanation:
8x = 12
x = 12/8 (12/4 / 8/4)
x = 3/2
x = 1.5
2y + 10 = 22
2y = 12
y = 6
1.5 + 6 = 7.5 = 7½
APEX PRE CALC: For a ____ function, the domain is broken into pieces, with a different rule defining the function for each piece.
Answer:
Piecewise
Step-by-step explanation:
For a piecewise function, the domain is broken into pieces, with a different rule defining the function for each piece.
Piecewise functions are usually a function that equals two or more equations depending on the x or the domain.
Google piecewise functions to see examples.
I hope this helps!
Answer: Piecewise
Step-by-step explanation:
There will be breaks and jumps in the curve, particularly when a value would undefined. So the solution curve looks like disconnected pieces.

Answer:
x^2 - 4x - 3
Step-by-step explanation:
f(x) = x^2 - 6x
g(x) = -2x + 3
(f - g)(x) is the subtraction of the functions, f(x) - g(x)
You need to write it carefully using parentheses for function g(x).
(f - g)(x) = f(x) - g(x) =
= x^2 - 6x - (-2x + 3)
Now take care of the parentheses by distributing the negative sign to its left. It will change every sign inside the parentheses.
= x^2 - 6x + 2x - 3
= x^2 - 4x - 3
how do i do this? -X= 8
Answer:
x = -8
Step-by-step explanation:
-X= 8
Multiply by -1
-X*-1= 8*-1
x = -8
Answer:
x = -8
Step-by-step explanation:
Multiply both side of the equation by -1
-x(-1) = 8(-1)
On the x side, the negatives cancel each other out, making x positive.
On the 8 side, the negative makes the 8 into -8.
x = -8
(essentially, switch the negative/positive signs)
The picture shows the Alamillo bridge in Seville, Spain. In the picture m<1=58 and m<2=24. Find the measure of the supplement of <1= and of <2. Someone please help!
Answer:
Supplement of <1 = 122°
Supplement of <2 = 156°
Step-by-step explanation:
Two pairs of angles are said to be supplementary, if their measures in degrees add up to give us 180°. A supplement of am angle is simply 180° - the measure of that angle.
Given that meadure of angle 1 = 58°, the supplement of angle 1 = 180° - 58° = 122°
Also, if the measure of angle 2 = 24°, the supplement of angle 2 = 180° - 24° = 156°.
Thus:
Supplement of <1 = 122°
Supplement of <2 = 156°

Point B lies on AC between A and C. If AB = 8 and AC = 10, find BC.
A. 2
B. 8
C. 10
D. 18
Answer:
BC = 2
Step-by-step explanation:
If B lies on AC it makes the line segments AB and BC.
AC=10
AB+BC=AC
AB+BC=10
8+BC=10
BC=2
The value of BC is 2 which is the correct answer that would be an option (A).
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment AC , where the length of line segment AC refers to the distance between its endpoints, A and C.
Point B lies on AC between A and C.
A______________B______________C
Given that B lies on AC it makes the line segments AB and BC.
AB = 8 and AC = 10
⇒ AB + BC = AC
⇒ AB + BC = 10
⇒ 8 + BC = 10
⇒ BC = 2
Therefore, the value of BC is 2 which is the correct answer that would be an option (A).

You are correct.
C is the constant, which is also called the slope.
Slope = change in y over the change in x:
Slope = 160-30 / 16-3 = 130/13 = 10
The equation would be y = 10x

Given JB is the segment bisector of AD, AD = 24 and AZ: 2x + 4 Find the value of x.
(ps the side cut off on the right is just point d)
Answer:
x = 4
Step-by-step explanation:
Since JB is the bisector of AD and the length of AD is given as 24 we can conclude that AZ is 12 (half of AD)
2x + 4 = 12
2x = 8
x = 4
A cyclist rode 3.75 miles in 0.3 hours. How fast was she going in miles per hour? Round your answer to the tenths (first) decimal place.
Answer:
12.5 miles per hour
Step-by-step explanation:
The speed is the distance divided by time.
3.75 miles/0.3 hours= 12.5 miles per hour
Answer:
12.5 miles per hour
Step-by-step explanation:
To answer this question you have to make sure that the hours (denominator) equals to 1. To do this, divide 3.75 by 0.3, thus making the 0.3 hours into 1 hour. This results in 12.5 miles per hour, the correct answer. Hope this helped!

Find the distance between (-4,5) and (4,0) round to the nearest hundredth
Answer:
Solution: 9.43
Step-by-step explanation:
Remember that we can determine the distance between any two points using the distance formula, d = √(x₂ - x₁)² + (y₂ - y₁)². Let's substitute known values to determine the distance:
[tex]\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2},}\\ \\\\\mathrm{d}= \sqrt{(4 - (-4))^2 + (0 - 5)^2} = \sqrt{(4 + 4)^2 + (- 5)^2} \\= \sqrt{(8)^2 + 25} = \sqrt{64 + 25} = \sqrt{89}[/tex]
Hence the distance between the points (-4,5) and (4,0) is exactly √89. The question asks us to round off to the nearest hundredth, so your solution will be approximated off to two digits → 9.43.

Step-by-step explanation:
just answered it
The transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.
Option (C) is correct.
It is required to choose the transformations of the graph.
What are transformations?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
We have a given a graph of y = f(-x) – 7.
The transformations in order are the following:
Reflection over the x-axis.
Horizontal translation of 7 units to the left.
Therefore, the transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.

In the diagram below of triangle KLM, N is a midpoint of KL and P is a midpoint
of LM. If mZPNL = 2x + 61, and MKN = 97 - 7x, what is the measure of
ZPNL?
Answer:
Solution:
(1/12)^(-2b) * 12^(-2b+2) = 12
(12^-1)^(-2b) (12)^(-2b+2) = 12
(12^2b)(12)^(-2b+2) = 12
12^(2b-2b+2) = 12
12^2 = 12

No solution.
Step-by-step explanation:
The measure of angle PNL will be equivalent to 69 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle KLM such that N is a midpoint of KL and P is a midpoint of LM.
Triangles LMP and LKM are similar to each other. Therefore, PN will be parallel to MK. So angle PNL will be equal to angle MKN. Therefore -
2x + 61 = 97 - 7x
9x = 97 - 61
9x = 36
x = 4
So, angle PNL will be equal to -
2 x 4 + 61
69 degrees
Therefore, the measure of angle PNL will be equivalent to 69 degrees.

A text message plan costs $2 per month plus $0.23 per text. Fine the monthly cost for x text messages
Answer:
y= 2 + 0.23x
Step-by-step explanation:
Giving the following information:
A text message plan costs $2 per month plus $0.23 per text.
First, we need to structure the total cost formula:
y= total cost
x= number of text messages
y= 2 + 0.23x
Now, we can calculate the total cost for any number of text:
x= 200
y= 2 + 0.23*200
y= $48

O (-1,0) and (3,0)
O (0, -1) and (0,3)
O (-1,0), (3, 0), and (0, -3)
From the graph, we can see that the graph crosses the y-axis at (0,-3) Hence, the correct answer is A (0,3).
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
The y-intercept is where a line crosses the y-axis, so this is the point where x = 0.
From the graph, we can see that the graph crosses the y-axis at (0,-3)
Hence, the correct answer is A (0,3).
