We set up the equation as follows:
Let x be the first integer
[tex]x+x+1+x+2+x+3=26[/tex]We solve for x:
[tex]\begin{gathered} 4x+6=26 \\ \\ 4x=26-6 \\ \\ x=\frac{20}{4} \\ \\ x=5 \end{gathered}[/tex]The value of the first integer is 5
Determine the slope of the line represented by the equation: y=3/10x+6

Which equation represents a line which is parallel to y=0?A. x=1B. y=x+3C. y=xD. y=6
ANSWER
D. y = 6
EXPLANATION
Parallel lines have the same slope.
In this problem, the given line is y = 0, which is a horizontal line at y = 0. Because it is a horizontal line, its slope is 0. From the options, we have to find which line has a slope of 0.
• Option A: x = 1 is a vertical line passing through x = 1. Its slope is undefined → ,not parallel,.
,• Option B: the slope of this line is 1 → ,not parallel.
,• Option C: the slope of this line is also 1 → ,not parallel.
,• Option D:, y = 6 is also a horizontal line, so its slope is 0 → ,this line is parallel ,to the given line.
Part of the proceeds from a garage sale was $305 worth of $5 bills if there were ) more bills than $20 bills find the number of each denomination
We are asked how many $20 bills and $5 bills can make up $305. To do that we will first divide 305 and 20, like this:
Now, we need to find a number that when multiplied by 20 is the closest to 305, that number is 15, since:
[tex](15)(20)=300[/tex]Therefore:
Now, subtract 300 from 305 and we get:

Given the graph of an inequality, you can identify that the boundary has the form of a "V". Therefore, you can identify that it is an Absolute Value Inequality.
By definition, an Absolute Value Equation written in Vertex Form is:
[tex]y=a|x-h|+k[/tex]Where "h" is the x-coordinate of the Vertex, and "k" is the y-coordinate of the Vertex. If "a" is negative, the graph opens down and if it is positive, the graph opens up.
In this case, the graph opens up, and you can identify in the graph that the Vertex is:
[tex]\mleft(-1,0\mright)[/tex]You can also identify that the boundary is formed by solid lines and the shaded region is below the boundary. This indicates that the inequality has this form:
[tex]\begin{gathered} y\leq a|x-(-1)| \\ \\ y\leq a|x+1| \end{gathered}[/tex]Notice that this inequality is given in the Answer choices:
[tex]y\le\mleft|x+1\mright|[/tex]In order to check it, let's choose two points on the shaded region:
[tex]\mleft(-2,-1\mright),(2,-2)[/tex]Substitute the coordinates into the inequality and evaluate. If they satisfy the inequality, then the are solutions to it:
- For the first point:
[tex]\begin{gathered} -1\le|-2+1| \\ \\ -1\le1\text{ (True)} \end{gathered}[/tex]- For the second point:
[tex]\begin{gathered} -2\le|2+1| \\ \\ -2\le3\text{ (True)} \end{gathered}[/tex]Hence, the answer is: Second option.

What rule describes a dilation with a scale factor of 1/2 and the center of dilation at orgin.
Explanation:
When we dilate a point by a scale factor "a" and the center of the dilation is the origin, the original point (x,y) changes as follows:
[tex](x,y)\rightarrow(ax,by)[/tex]Each coordinate value is multiplied by the scale factor.
In this case, the scale factor is 1/2:
[tex]a=\frac{1}{2}[/tex]Therefore, the transformation rule is:
[tex](x,y)\rightarrow(\frac{1}{2}x,\frac{1}{2}y)[/tex]This rule is shown in option C.
Answer:
C.

Find the savings to thenearest cent on buying 96 ounces of applesauce in 16-oz. cans compared to 12-oz. cans.$6.98$7.87$8.12$9.06None of these choices are correct.
To do the comparison, we need to calculate the cost of buying 96 ounces using both options.
For 16-oz can
The number of cans required to get 96 ounces will be
[tex]\begin{gathered} \frac{96}{16} \\ =6\text{ cans} \end{gathered}[/tex]The cost will be
[tex]\begin{gathered} 6\times7.78 \\ =46.68 \end{gathered}[/tex]The cost of 96 ounces of applesauce in 16-oz cans is $46.68.
For 12-oz can
The number of cans required to get 96 ounces will be
[tex]\begin{gathered} \frac{96}{12} \\ =8\text{ cans} \end{gathered}[/tex]The cost will be
[tex]\begin{gathered} 8\times6.85 \\ =54.80 \end{gathered}[/tex]The cost of 96 ounces of applesauce in 16-oz cans is $54.80.
The savings on buying in 16-oz cans will be
[tex]\begin{gathered} 54.80-46.68 \\ =8.12 \end{gathered}[/tex]The savings will be $8.12.
Parts of a CircleFor this assignment, you will draw and label the parts of a circle. Follow the directions below to construct your circle.

If you do not have a scanner, you may take a picture with a digital camera or cell phone and then embed the image into a Word document.Draw circle A.Draw radius AB.Draw diameter CD.Draw chord EF.Draw central angle GAH.
It's important to consider that a radius is a segment from the center of the circle to the circumference, diameter is a segment that crosses the center of the circle and divides the circle into two equal parts, a chord is a segment that goes from one point on the circumference to another without intersecting the center of the circle, at last, a central angle is an angle formed by two radii and it has the center as the vertex.
First, let's draw circle A.
Second, let's draw radius AB.
Third, let's draw diameter CD.
Fourth, let's draw chord EF.
At last, let's draw angle GAH.

The equation of the line in fully simplified slope intercept form is y = -5x + 8.
From the graph:
Take any two points:
suppose (1,3) and (2,-2)
slope m = y2 - y1 / x2 - x1
= -2 - 3 / 2 - 1
= -5/1
= -5
substitute m and (1,3) in y = mx + c
3 = -5*1 + c
3 = -5 + c
c = 3+5
c = 8
y = mx+c
y = -5x + 8.
Therefore the equation of the line in fully simplified slope intercept form is y = -5x + 8.

The triangles ABC and JGH are similar figures.
For two figures to be simmilar, the coresponding angles must be congruent and the corresponding sides must be proportional.
For these triangles:
The corresponding sides of the simimilar figures are proportional, you can express this as:
[tex]\frac{JH}{AC}=\frac{JG}{AB}=\frac{GH}{BC}[/tex]This expression indicates that the proportion between the corresponding sides is the same for all three pairs of sides. Using this information, we can determine the value of side GH
The proportion between the corresponding sides of the triangles is:
[tex]\frac{JH}{AC}=\frac{5.8}{11.6}=\frac{1}{2}[/tex]Now calculate GH as:
[tex]\begin{gathered} \frac{GH}{BC}=\frac{1}{2} \\ \frac{x}{6}=\frac{1}{2} \\ x=(\frac{1}{2})\cdot6 \\ x=3 \end{gathered}[/tex]Now the corresponding angles of the similar figures must be congruent, i.e. have the same measure so that:
[tex]\begin{gathered} \angle A=\angle J=31º \\ \angle C=\angle H=59º \end{gathered}[/tex]So a and y are

Recall how to find the mean, the median, the midrange and the mode of a data set.
To find the mean, add all the values and divide the result over the amount of values:
[tex]\frac{15+11+4+15+9+7+12+5+15}{9}=\frac{93}{9}=10.333...\approx10.3[/tex]To find the median, list the data from smallest to largest and identify the number that is placed at the middle of the list. If the number of data points is even, the median is the average of the two middle data points in the list:
[tex]4,5,7,9,11,12,15,15,15[/tex]In this case, the median is 11 because there are 4 numbers before it and 4 numbers after it.
To find the midrange, calculate the mean between the minimum and maximum numbers of the data set:
[tex]\frac{4+15}{2}=9.5[/tex]The mode is the value that appears most frequently in the data set. In this case, the number 15 appears three times and the rest just 1. Then, the mode is 15.
Therefore, the answers are:
