Answer:
y=3/4x-14
Step-by-step explanation:
Remember that slope-intercept form is y=mx+b
We can see that our givens is that the slope is 3/4 and our point is (8,-8)
Let's plug this in and solve for b (b is the y-intercept)
-8=3/4*8+b
-8=24/4+b
-8=6+b
-14=b
Now we write out the equation which is y=3/4x-14

Gary wanted to determine the average height of boys at the high school. His older brother is on the basketball team, so he asked him to measure his teammates. After interpreting the results, Gary determined the average height of a high-school-aged boy to be 6 feet, 1 inch. HELP ASAPPPPP
Would you consider these results to be valid?
Yes, because only high-school boys were surveyed.
Yes, because the results were obtained randomly by measuring the boys basketball team.
No, because boys on the basketball team are likely to be taller than the average high school boy.
No, because there are no girls surveyed.
Answer:
The answer would be "no because boys on the basketball team are likely to be taller than other boys at the school"

What is the value of x?
Answer:
x = 88 -5y/2
Step-by-step explanation:
(2x - 4) + 5y + x = 180
x = 180 - (2x - 4) -5y -x
x = 180 - x - 4 -5y
x = 176 - x -5y
2x = 176 - 5y
x = 88 -5y/2

The mean, median, mode, and range of the data set will be 7.5, 8, 8, and 2, respectively.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.
The quantities of hours mary works over a time of 8 days are 8, 7, 8, 8, 8, 7, 6, and 8.
Arrange the data in increasing order, then we have
6, 7, 7, 8, 8, 8, 8, 8
The mean of the data is given as,
Mean = (6 + 7 + 7 + 8 + 8 + 8 + 8 + 8) / 8
Mean = 60 / 8
Mean = 7.5
The median of the data is given as,
Median = {[8 / 2 + (8 + 2)/ 2] / 2}
Median = (4th + 5th) / 2
Median = (8 + 8) / 2
Median = 16 / 2
Median = 8
The mode of the data is given as,
Mode = Frequency of the number
Mode = 8
The range of the data set is given as,
Range = 8 - 6
Range = 2
The mean, median, mode, and range of the data set will be 7.5, 8, 8, and 2, respectively.

Consider the enlargement of the pentagon. A small pentagon has a bottom side length of x centimeters and left side length of 7 centimeters. A larger pentagon has a bottom side length of 7 centimeters and left side length of 15 centimeters. Not drawn to scale What is the value of x, rounded to the nearest tenth? 2. 1 centimeters 3. 3 centimeters 7. 0 centimeters 15. 0 centimeters.
When the pentagon is drawn to scale then its value of x will be x=3.3 cm
What is the pentagon?The pentagon is defined as the shape having five sides connected together.
Now it is given in the question that
For small pentagone
Bottom =x
left =7 cm
For larger pentagone
Bottom=7cm
left=15cm
Now since the pentagon is actually dilated from its size to the new bigger size. It means that the equivalent ratio of both the pentagons will be equal.
For smaller pentagon
[tex]\rm Equivalent \ Ratio = \dfrac{Bottom}{Left} =\dfrac{x}{7}[/tex]
For bigger pentagon
[tex]\rm Equivalent \ Ratio = \dfrac{Bottom}{Left} =\dfrac{7}{15}[/tex]
Since both, the ratio is the same
[tex]\dfrac{x}{7} =\dfrac{7}{15}[/tex]
[tex]x=\dfrac{49}{15} =3.3\ cm[/tex]
Thus the pentagon is drawn to scale than its value of x will be x=3.3 cm

Julian has a points card for a movie theater. He receives 85 rewards points just for signing up. He earns 3.5 points for each visit to the movie theater. He needs 120 points for a free movie ticket. Which equation or tape diagram could be used to represent the context if xx represents the number of visits Julian must make to earn a free movie ticket?
Answer:
an equation that can be used to represent the number of visits needed to earn a free movie ticket is
3.5x+85=120
Step-by-step explanation:
you would multiply 3.5 by the number of visits (x) to determine how many points Julian would have earned in total. you would add 85 to the product of 3.5(x) because he had started with 85 points.
if you want to find how many times Julian would need to visit the movie theater to get a free movie ticket you can subtract 85 from 120, to find out how many visits are necessary before adding the extra 85 points. subtracting that leaves you with 35, and if you divide that by 3.5, the number of points per visit, you are left with 10. Julian would need to visit the theater 10 times before earning a free movie ticket.
if you want to check to see if that's right, you can just do the equation in reverse. rather than 85-120=35/3.5=10, you can do 10*3.5=35+85=120

What is the area of this figure?
Answer:
234 mm^2
Step-by-step explanation:
These questions are tricky but to make them easier, try to break down the shape into smaller regular shapes and work them out.
I would divide this shape into 2 rectangles and one triangle
Area of small bottom rectangle: 4 x 11 = 44mm^2
Area of rectangle in the middle: 14 x 8 = 112mm^2
Area of triangle: 12 x 13/2 = 78mm^2
Add all the areas together = 44+112+78 = 234mm^2

find the missing side length please!
Answer:
20.25
Step-by-step explanation:
The area of a rectangle is calculated by multiplying its width and length:
The area of the smaller rectangle is given as 9 ft^2 so to find its width we divide the given area with length which is 4.5
9/(4.5) = 2
The given rectangles are similar so their side lengths must be proportional
(4.5)/x = 2/9 cross multiply expressions
2x = 40.5 divide both sides by 2
x = 20.25

First, complete the sentence to show how the figure can be decomposed into triangles and rectangles with the fewest number of pieces.
Then find the area of the divisions.
The figure can be divided into a triangle and a rectangle.
The area of a triangle is 10 sq inches.
The area of a rectangle is 80 sq inches.
The total area of the figure is 90 sq inches.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
The figure can be divided into a triangle and a rectangle.
The height of the triangle is 2 inches and the base is 10 inches.
We know the area of a triangle is (1/2)×base×heiht.
∴ Area = (1/2)×10×2 sq inches.
Area = 10 sq inches.
We know the area of a rectangle is length×width.
∴ Area = (10×8) sq inches.
Area = 80 sq inches.
The total area of the figure is (10 + 80) sq inches = 90 sq inches.
