Slope of the line formed by points (-1,-2) and (3,-3) is Slope=\frac{-1}{4}

Step-by-step explanation:

We need to find slope of the line formed by points (-1,-2) and (3,-3)

Finding slope:

The formula used is:

Slope=\frac{y_2-y_1}{x_2-x_1}

here, x_1=-1,y_1=-2,x_2=3,y_2=-3

Putting values and finding slope:

Slope=\frac{y_2-y_1}{x_2-x_1}

Slope=\frac{-3-(-2)}{3-(-1)}

Slope=\frac{-3+2}{3+1}

Slope=\frac{-1}{4}

So, slope of the line formed by points (-1,-2) and (3,-3) is Slope=\frac{-1}{4}

Write down the 3rd term in the sequence given by: T(n) = n2 + n
Sergio [31]
The solution for the problem is:
I will first get the first five terms so that I could easily locate the third term of this problem:So, substituting the values:
T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25
So the third terms is T(3) = 3^2 = 9

PLEASE HELP DUE TOMORROW 1. An artist is selling children’s crafts. Necklaces cost 2.25 each and bracelets cost 1.50 per each. a
Tems11 [23]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost per bracelet = 1.50

Cost per necklace = 2.25

Let :

number of necklace = n

Number of bracelet = b

Cost equation C ;

C = 1.5b + 2.25n

Number of necklace that could be sold for exactly $12

5 necklaces and 1 bracelet :

1.5 + 2.25(5) = 12.75

•2 necklaces and 5 bracelets:

1.5(5) + 2.25(2) = 12

• 3 necklaces and 3 bracelets

1.5(3) + 2.25(3) = 11.25

• 4 necklaces and 2 bracelets

1.5(2) + 2.25(4) = 12

• 3 necklaces and 5 bracelets

1.5(5) + 2.25(3) = 14.25

• 6 necklaces and no bracelets •

1.5(0) + 2.25(6) = 13.5

No necklaces and 8 bracelets

1.5(8) + 2.25(0) = 12

Amount charged per Tshirt = c

Setup fee = $40

Number of students in drama club = 21

Total cost of order = $187

Calculate C ;

Total order cost = set up fee + (cost per shirt * number of shirts)

Total order cost = 40 + 21c

187 = 40 + 21c

187 - 40 = 21c

147 = 21c

c = 147 / 21

C = 7

Hence cost per shirt = $7
