From the graph the at x-intercept

(-3, \: 0)
(0, \frac{ - 3}{4} )

Using the intercepts ,the equation is given by,

\frac{x}{a}  +  \frac{y}{b}  = 1

where
a =  - 3
and
b =  \frac{ - 3}{4}
This implies that

\frac{x}{ - 3}  +  \frac{y}{ \frac{ - 3}{4} }  = 1


This implies that

x + 4y =  - 3
Multiplying through by 2 gives

2x + 8y =  - 6
<b> The correct answer is D </b>

(-3,0) and (5, -2)

slope = (0 + 2)  /(-3 - 5) = -2/8

y - 0 = -2/8 (x + 3)

y = -2/8 x - 6/8

8y = -2x - 6

2x + 8y = - 6

Answer is

D. 2x + 8y = -6

A pot is being used to boil off 1 kg of water. The specific energy required to cause the phase change is 2297 kJ/kg. Assuming th
lana66690 [7]

Answer:

It will take 58 seconds

Step-by-step explanation:

If you have 1 kg of water in the jar, half of it will be 0.5 kg.

To vaporize half of the water (0.500 kg) the energy supply needed is

2297 kJ/kg*0.5kg=1148.5 kJ

If the stove is supplying 20 kJ/s, the time its needed is

\frac{1148.5 kJ}{20\frac{KJ}{s} }=57.425 s

It will last at least 58 seconds to vaporize half of the water.

A rectangle school banner has a length of 44 inches, a perimeter of 156 inches , and an area of 1496 square inches. The cheerlea
Andrej [43]
Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.

So, 44 ÷ 4 = 11.

For the perimeter, 156 ÷ 4 is 39.

For the area, you have to do A=bh
(Area = base × height)

The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.

Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2

The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in

I hope that helps!

Two lines, A and B, are represented by the equations given below:
SashulF [63]
Given:
Line A: 2x +  2y = 8
Line B:    x + y = 4

x = 4 - y
2(4-y) + 2y = 8
8 - 2y + 2y = 0
0 = -8

y = 4 - x
2x + 2(4-x) = 8
2x + 8 - 2x = 8
0 = 0

There is no solution.
