Answer:

Area= L*W= 13*7 = 91ft^2

Step-by-step explanation:

L= 6+W

Perimeter of the rectangle=2(L+W)=40

2(6+W+W)=40

2(6+2W)=40

12+4W=40

4W=40-12

4W=28

W=28/4

W=7ft

L=6+7=13ft

Area=L*W=13*7=91ft^2

An equation of a line through (-1, 4) which is perpendicular to the line y = 4x + 1 has slope and y-intercept
Assoli18 [71]

Answer:

The answer to your question is   y = -1/4x + 15/4

Step-by-step explanation:

Data

P (-1, 4)

⊥ y = 4x + 1

Process

1.- Find the slope of the line given

       y = 4x + 1

slope = 4

2.- Find the slope of the new line

     slope 2 = -1/4

3.- Find the equation of the line

       y - y1 = m(x - x1)

Substitution

       y - 4 = -1/4(x + 1)

Simplification

       y - 4 = -1/4x - 1/4

       y = -1/4x - 1/4 + 4

       y = -1/4x - 1/4 + 16/4

Result

       y = -1/4x + 15/4

Mariah spent $9.50 on 9 pounds of limes and pears. Limes cost $0.50 per pound and pears cost $1.50 per pound. Let l be the numbe
Mashcka [7]

Answer:

4 pounds of lime and 5 pounds of pears

Step-by-step explanation:

I + P = 9

0.5l + 1.5P = 9.5

I = 9 - P

0.5(9 - P) + 1.5P = 9.5

4.5-0.5P + 1.5P = 9.5

4.5 + P (1P) = 9.5

P = 9.5-4.5 = 5

I = 9 - 5 = 4

Answer: 4 pounds of lime and 5 pounds of pears

Write the equation for the quadratic function in the graph
Hoochie [10]

Answer:

{x}^{2}  - 16 = 0 \: is \: the \: equation

Step-by-step explanation:

x =  - 4 \\ or \: x = 4

(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket

x(x - 4) + 4(x - 4) = 0

{x}^{2}  - 4x + 4x - 16 = 0 \\  {x}^{2}  - 16 = 0
