John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling live bait for $12 a pound and natural bait for $7 a pound. John would like to get at least 3 pounds of live bait, but he only has a budget of $63. Let be the amount of live bait and be the amount of natural bait.
Answers
Answer:
Step-by-step explanation:
x= live bait and y= natural bait
12x+7y=63
x>3
x can be anywhere between 3 and 5.
when x=3, y=3
when x=4, y=2
when x=5, y=0
you can get 3 pounds of each bait and have 1 dollar left

Mr. collins counts 54 Cartons and 5 boxes of paper clips Each carton contains 8 boxes a box of paper clips cost $2How many How many boxes are clips does he have?
Answers
The number of boxes of clips that Mr. Collins has is 437 boxes.
In order to determine the number of boxes of clips that Mr. Collins has, we have to determine the number of boxes of clips in the 54 cartons.
The boxes of clips in the carton can be determined by multiplying 54 by 8
The boxes of clips in the carton = 54 x 8 = 432
The second step is to add 432 to 5.
432 + 5 = 437 boxes

3(x+2) = 2(x+5)? What does it equal?
Answers
Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
x = 4
Step-by-step explanation:
Original Equation:
3(x + 2) = 2(x + 5)
Use distributive property
3 · x = 3x
3 · 2 = 6
Your equation should look like this now:
3x + 6 = 2(x + 5)
Use distributive property for the other side
2 · x = 2x
2 · 5 = 10
Your equation:
3x + 6 = 2x + 10
Subtract 6 from both sides
3x = 2x + 4
Subtract 2x from both sides
1x = 4
Divide both sides by 1
x = 4

Enter the equation of the line in slope-intercept form.
The line parallel to y = −x that passes through (7, 2.5).
The equation of the line that passes through (7, 2.5) is y = .
Answers
Given:
The line parallel to y = −x that passes through (7, 2.5).
To find:
The slope intercept form of the given line.
Solution:
Slope intercept form of the line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
On comparing y = −x with slope intercept form, we get
[tex]m=-1[/tex]
So, slope of y=-x is -1.
Slope of parallel lines are same. Thus, slope of required line is -1.
Required line passes through (7,2.5) with slope -1. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-2.5=-1(x-7)[/tex]
[tex]y-2.5=-x+7[/tex]
Add 2.5 on both sides.
[tex]y-2.5+2.5=-x+7+2.5[/tex]
[tex]y=-x+9.5[/tex]
Therefore, the equation of the line that passes through (7, 2.5) is [tex]y=-x+9.5[/tex].

B: The rate of change in linear functions is always a constant slope, the m value.
C: The initial value of a linear function could be zero. It depends on the line.
D: It makes sense that the graph of a linear function is a line.
E: A vertical line is not a function. You can do the vertical line test: if a vertical line were to hit more than one point at a single x-value, the line is not a function.

Answer:
y - 5 = - [tex]\frac{3}{5}[/tex](x + 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Given
5x = 3y , that is
3y = 5x ( divide both sides by 3 )
y = [tex]\frac{5}{3}[/tex] x ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{3} }[/tex] = - [tex]\frac{3}{5}[/tex] and (a, b) = (- 5, 5), then
y - 5 = - [tex]\frac{3}{5}[/tex] (x - (- 5) ), that is
y - 5 = - [tex]\frac{3}{5}[/tex] (x + 5) ← equation of perpendicular line
