This is how you would determine the equation and solve the problem:
- First, it is important that you find how much each eraser cost. You do know that 66 erasers cost $6.60. So create an equation.
- The equation would be: 66/6.60
which means each eraser was 10 cents each
- Now you can create a equation that would determine the cost of 333 erasers since you know how much each eraser actually cost. The equation would be:
- .10×333=?
To create that equation all you need to do is multiply the price of the erasers (10 cents) by how many erasers you are buying (333).

If the graph of y = 72 + 6 is translated 4 units down, which equation describes the new graph?
y = 112 + 6
y=73 + 2
y = 72 +10
O
y = 3x + 6
\left. \begin{array} { l } { y = 112 + 6 }\\ { y = 73 + 2 }\\ { y = 72 + 10 }\\ { y = 3 x + 6 }\\ { \text{Solve for } z \text{ where} } \\ { z = 0 } \end{array} \right.
Answer:
B. y = 7x + 2Step-by-step explanation:
Given function
y = 7x + 6Translation down or up by m units = y + m
y - 4 is7x + 6 - 4 =7x + 2So it is
y = 7x + 2Correct option is B.

I am legit doing this in school but I don't know it lol
Answer:
y = 6x + 4
Step-by-step explanation:
(x₁ , y₁) = (-2 , -8) & (x₂ , y₂) = (2 , 16)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{16-[-8]}{2-[-2}\\\\=\frac{16+8}{2+2}\\\=\frac{24}{4}\\\\= 6[/tex]
m = 6
y - y₁ = m(x - x₁)
y - [-8] = 6(x -[2])
y + 8 = 6(x + 2)
y + 8 = 6x + 6*2
y + 8 = 6x + 12
y = 6x + 12 - 8
y = 6x + 4
The expression 3h? + 4 represents the total amount of grain, in pounds, that is harvested
on a farm h hours into each workday. If the harvesting rate continues to follow this
model, which inequality represents the time, in hours, when the total amount of grain
harvested will be at most 100 pounds?
Answer:
B. [tex] 3h^2 + 4 \le 100 [/tex]
Step-by-step explanation:
total amount of grain, in pounds, harvested = [tex] 3h^2 + 4 [/tex], where, h = hours.
If at most 100 pounds will be harvested, it means the what will be harvested in pounds after working for some h hours, would be 100 pounds or less than 100 pounds. The highest is 100 pounds. "At most 100 pounds" means "less than or equal to 100 pounds".
The inequality that represents the time in hours would be:

700
61
6100
610
Answer:
The first number to subtract is 610
Step-by-step explanation:
In the division of 742 by 61, the first thing to do is to divide 742 by 61 straight and we get 10
So multiplying 10 by 61, we get 610
This is what we proceed to subtract from 742
So the first number to subtract is 610
Answer: 610

If a*b=(a-b)², calculate 2*5
I suppose * is supposed to denote a binary operation with the given definition,
a * b = (a - b)²
as opposed to multiplication, so that, for instance, 1 * 1 = (1 - 1)² = 0.
Using the definition of *, you have
2 * 5 = (2 - 5)² = (-3)² = 9

Without graphing, find the slope of the line that goes through
1. (0,5) and (8,2).
2. (2,-1) and (6,1). 1/2
3. (-3,-2) and (-1,-5).
Answer:1/2,-3/2,-3/8
Step-by-step explanation:
The slope of the lines are -3/8, 1/2 and -7/2 respectively.
A linear equation is given by:
y = mx + b
Where y, x are variables, m is the slope of the line and b is the y intercept.
1) The slope (m) of the line that goes through (0,5) and (8,2). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{2-5}{8-0}\\\\m=-\frac{3}{8}[/tex]
2) The slope (m) of the line that goes through (2, -1) and (6,1). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{1-(-1)}{6-2}\\\\m=\frac{1}{2}[/tex]
3) The slope (m) of the line that goes through (-3, -2) and (-1, -5). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-5-2}{-1-(-3)}\\\\m=-\frac{7}{2}[/tex]
The slope of the lines are -3/8, 1/2 and -7/2 respectively.
