Mrs. Morales wrote a test with 15 questions covering spelling and vocabulary. Spelling questions (x) are worth 5 point and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100.Write an equation in slope-intercept form to represent the number of questions on the test.
Write an equation in slope-intercept form to represent the total number of points on the test.
Graph the solution for both equations.
Use your graph to tell how many of each question type are on the test.

Answers

Ok, so you are basically finding a solution of equations.
x + y = 15, since there are 15 questions.
5x +10y = 100, since the maximum number of points is 100
Now what you do is change the equations to slope intercept form, which changes to y = -x+15
and y = 1/2x + 10
I assume you can graph these?

Ballpoint pens cost $1.50 a dozen for the first 200 dozen a store buys from a wholesaler and $1.25 a dozen for those bought in addition to the first 200 dozen. If the store buys 250 dozen pens from the wholesaler, then what is the average cost of ballpoint pens per dozen.

Answers

Solution:

We are given that

Ballpoint pens cost $1.50 a dozen for the first 200 dozen a store buys from a wholesaler.

$1.25 a dozen for those bought in addition to the first 200 dozen.

we have been asked to find

If the store buys 250 dozen pens from the wholesaler, then what is the average cost of ballpoint pens per dozen.

Cost of first 200 dozens of pens $=1.5*200=300dollars$

Cost of 50 dozens of pens $=50*1.25=62.5 dollars$

Total cost of 250 dozens of pens $=300+62.5=362.5dollars\n$

Average cost per dozen $=(362.5)/(250)= 1.45dollars$

4b×3b-2b=102 what is b

Answers

4b×3b-2b=102
12b^2 - 2b = 102
12b^2 - 2b - 102 = 0
divide by 2
6b^2 - b - 51
(6b + 17)(b - 3) = 0
6b + 17 = 0
6b = -17
b = -17/6 or 2 5/6
b - 3 = 0
b = 3

$4b\cdot3b-2b=102\n 12b^2-2b-102=0\n 6b^2-b-51=0\n 6b^2+17b-18b-51=0\n b(6b+17)-3(6b+17)=0\n (b-3)(6b+17)=0\n\ b=3 \vee b=-(17)/(6)$
