The length of a side of square a is 7 more than the length of a side of square

1 answer:

8 0

(8x+32)/4= 2x+8
2x+8=y+7 With y being the length of a side of square b
y=2x+1
Perimeter of square b: 4(2x+1)=8x+4

Or you could just do this:
32-4(7)=4 so Perimeter of b is 8x+4

Solve for c R=5(c/a-0.3)

aalyn [17]

we have

$R=5(c/a-0.3)$

Solve for c--------> that means that clear variable c

Divide by $5$ both sides

$R/5=(c/a-0.3)$

Adds $0.3$ both sides

$(R/5)+0.3=(c/a)$

Multiply by $a$ both sides

$a[(R/5)+0.3]=c$

$c=a[(R/5)+0.3]$

therefore

the answer is

$c=a[(R/5)+0.3]$

What is the slope of this graph?

pishuonlain [190]

Answer:

Slope = -1

Step-by-step explanation:

Since, slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

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

Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,

Slope = $\frac{4-2}{1-3}$

= (-1)

Therefore, slope of the line is (-1).
