A sports camp has a total of $2,880 to purchase new equipment. They need baseballs and baseball gloves. A pack of baseballs cost

s $16, and a glove costs $48. The camp needs to include at least 50 items in its order. Let x represent the number of gloves and y represent the number of packs of baseballs. Draw a graph to represent the number of packs of baseballs and baseball gloves the camp can purchase with its budget.

Answer:

Step-by-step explanation:

Problem to start doing linear programming, excellent.

Number of packs of baseballs to be purchased = x

Cost of a pack of baseballs,  C= 16

Number of gloves to be purchased = y

Cost of a glove, G = 48

Minimum number of items = 50   [x+y >= 50]

Maximum amount to be spent = 2880   [Cx + Gy <= 2880]

Graph drawn and attached.

Shaded area (grey) represent all feasible purchases.

Maximum number of pairs of gloves = 60 (zero balls), or

maximum number of sets of balls = 180 (no gloves)

Which system of linear inequalities is graphed?
ANEK [815]

To determine the system of inequality that has been graphed, we need to be very smart.


Observe that all the equations are the same.


Also note that all the lines are solid. This should tell you that the inequities should involve.


\ge \:or\: \le



Therefore the answer is between option A and B.



So we choose a point in the solution region to discriminate between A and B.


Let us choose the origin since that is easy to evaluate.


We substitute into option A to get.

y\le 3x-1\:and\: x+ 3y \ge 6




0\le 3(0)-1\:and\: 0+ 3(0) \ge 6




0\le -1\:and\: 0\ge 6


The above statements are false



We now substitute into option B



y\ge 3x-1\:and\: x+ 3y \le 6




0\ge 3(0)-1\:and\: 0+ 3(0) \le 6




0\ge-1\:and\: 0 \le 6


Both statements are true, therefore the correct answer is option B.

Answer:

2, 1, 1/2, 1/4

Step-by-step explanation:

2¹ = 2

2^0 = 1

2^-¹

= 1/2¹

= 1/2

2^-2

= 1/2²

= 1/2*2

= 1/4

To complete the table

2² 2¹ 2^0 2^-1 2^-2

4 2 1 1/2 1/4

A line has a slope of –5 and a y-intercept of (0, 3). What is the equation of the line that is perpendicular to the first line a
neonofarm [45]
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept

Data of the first line:
m=-5
b=y-intercept=3  (y-intercept=it is the value of "y" when x=0)

y=-5x+3

A line perpendicular to the line y=mx+b will have the following slope:
m`=-1/m

Therefore: the line perpendicular to the line y=-5x+3 will have the following slope:
m´=-1/(-5)=1/5

Point-slope form of a line: we need a point (x₀,y₀) and the slope (m):
y-y₀=m(x-x₀)

We know, the slope (m=1/5) and we have a point (3,2) therefore:
y-y₀=m(x-x₀)
y-2=1/5(x-3)     (point-slope form)
y-2=(1/5)x-3/5
y=(1/5)x-3/5+2
y=(1/5)x+7/5    (slope-intercept form)

Answer: the line perpendicular to the first line will be: y=(1/5)x+7/5
