The points that could be on the line
y = 7x - 16 are (-2, -30)
-30 = 7 X -2 - 16
-30 = -14 - 16
-30 = -30
Option B is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
A line has a slope = 7 and passes through the point (3, 5).
Now,
The equation of a line can be written as,
y = mx + c
m = 7
y = 3x + c
Now,
(3, 5) = (x, y)
5 = 7 x 3 + c
5 = 21 + x
5 - 21 = c
c = -16
The equation of the line.
y = 7x - 16
The points that could be on the line have to satisfy the equation.
y = 7x - 16
A.
(-1, -24)
y = 7 x -1 - 16 = -7 - 16 = -23
This is not true
B.
(-2, -30)
y = 7 x -2 - 16 = -14 - 16 = -30
This is true.
C.
(6, 24)
y = 7 x 6 - 16 = 42 - 16 = 26
This is not true.
D.
(10,55)
y = 7 x 10 - 16 = 70 - 16 = 54
This is not true.
Thus,
The points that could be on the line
y = 7x - 16 are (-2, -30)
-30 = 7 X -2 - 16
-30 = -14 - 16
-30 = -30
Option B is the correct answer.

A triangle has sides with lengths of 12 miles, 84 miles, and 85 miles. Is it a right triangle?
Answer:
[tex]\boxed {\boxed {\sf No}}[/tex]
Step-by-step explanation:
If a triangle is a right triangle, it can satisfy Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
12 and 84 are the legs because are they shortest. 85 is the hypotenuse because it is the longest side.
[tex]a= 12 \\b=84 \\c=85[/tex]
Substitute the values into the formula.
[tex](12)^2+(84)^2=(85)^2[/tex]
Solve the exponents.
12²= 12*12=14484²=84*84=7056 85²= 85*85=7225[tex]144+7056=7225[/tex]
Add on the right side.
[tex]7200\neq 7225[/tex]
7220 is not equal to 7225, so these sides cannot be a right triangle.
Solve the system by substitution. y = 6x – 20
y = -4x
Answer:
(2, -8)
Step-by-step explanation:
y=6x-20
y=-4x
since the bottom equation shows us that y=-4x, we can substitute 4x in place of y in the first equation and solve:
-4x=6x-20
-10x=-20
x=2
since the bottom equation shows y=-4x, and we already know that x=2:
y=-4(2)
y=-8

shown. Find the total surface area of the box.
cereal
13.5 in.
2.5 in.
8 in.
Total surface area?
Answer:
323.5 square inches
Step-by-step explanation:
The cereal box is not shown. However, the given details are enough to arrive at a solution
[tex]Length = 13.5in[/tex]
[tex]Width = 2.5in[/tex]
[tex]Height = 8in[/tex]
Required
The total surface area (TSA)
This is calculated as:
[tex]TSA = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
[tex]TSA = 2 * (13.5 * 2.5 + 13.5 * 8 + 2.5 * 8)[/tex]
[tex]TSA = 2 * (161.75)[/tex]
[tex]TSA = 323.5[/tex]
Hence, the total surface area is 323.5 square inches
Maggie has half as many apple muffins as she does blueberry muffins. Let b represent the number of blueberry muffins Maggie has.
Create an expression to represent the number of apple muffins Maggie has. Move a number, a variable, and a symbol to the lines to create
the expression.
Answer: b/2
Step-by-step explanation:
From the question, we are informed that Maggie has half as many apple muffins as she does blueberry muffins where,
b = the number of blueberry muffins that Maggie has.
Therefore, an expression to represent the number of apple muffins Mmthat Maggie has will be:
= 1/2 × b.

A total of 1,650 boxes of Girl Scout cookies were sold last week. Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group
earned $4,650. How many large boxes and how many small boxes of cookies were sold?
Answer:
900 large boxes were sold, and 750 small boxes.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of large boxes of cookies sold.
y is the number of small boxes of cookies sold.
A total of 1,650 boxes of Girl Scout cookies were sold last week.
This means that
[tex]x + y = 1650[/tex]
So
[tex]x = 1650 - y[/tex]
Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.
This means that
[tex]3.5x + 2y = 4650[/tex]
Since [tex]x = 1650 - y[/tex]
[tex]3.5(1650 - y) + 2y = 4650[/tex]
[tex]5775 - 3.5y + 2y = 4650[/tex]
[tex]1.5y = 1125[/tex]
[tex]y = \frac{1125}{1.5}[/tex]
[tex]y = 750[/tex]
[tex]x = 1650 - y = 1650 - 750 = 900[/tex]
900 large boxes were sold, and 750 small boxes.

A rectangular field is 62 meters long and 48 meters wide. Diane estimates the length of the field
to be 60 meters and the width to be 45 meters. What is the percent error of Diane's estimated
area measurement? Round your answer to the nearest whole percent.
Enter your answer in the space provided.
Answer:
9%
Step-by-step explanation:
Original area of the rectangle = length × width
= 62 × 48
= 2,976 m²
Diane area of the rectangle = length × width
= 60 × 45
= 2700 m²
Percent error = (original - estimated)/original × 100
= (2976 - 2700)/2976 × 100
= 276/2,976 × 100
= 0.0927419354838 × 100
= 9.2741935483870%
Approximately to the nearest whole percent = 9%

Step-by-step explanation:
Rise over run we see two points how many times do we rise and run to get there?
(Slope= rise/run)
So you rise 300 times (Since half of 600 is 300) then you run 1 time which is 300/1 which is 300
John and Adam are selling candy. John sells 6 pieces of candy for $10. Adam sells 13 pieces of candy for $20. Whose candy costs less?
Answer:
John sells candy at the lowest price.
Step-by-step explanation:
If John sells 6 candies at 10$, then that's what's called a ratio between the price and the candy. We can double the amount of candy and the price to $20 for each 12 candies, $30 for 24, $40 for 36, etc. But it would still maintain the ratio of 6 candies for each 10$. Adam however, sells candy at 13 pieces for $20. We can divide the ratio down to 6.5 candies for 10$. But since we "can't" split a candy in half, we'll round it to 7 pieces for 10$, which costs more than 6 for 10$: Therefore, John sells candy at the lower price.
