Assuming it is a square plate, and the area is 49 square cm, each side length should be 7. Length times width equals the area, and 7 times 7 is 49 square cm. Hope this helps!

Indicate in standard form the equation of the line passing through the given points, writing the answer in the equation

Kryger [21]

Answer:

$y + x - 6 = 0$

Step-by-step explanation:

Given

$M(0,6) \ and \ N(6,0)$

Required

Find the equation of the line

First, the slope of the line has to be calculated using the following formula;

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

$where\ (x_1,y_1) = (0,6) \ and \ (x_2,y_2) = (6,0)$

So, the equation becomes

$m = \frac{0 - 6}{6 - 0}$

$m = \frac{-6}{6}$

$m = -1$

The equation of the line can then be calculated using

$m = \frac{y - y_1}{x - x_1} \ or \ m = \frac{y - y_2}{x - x_2}$

$Using \ m = \frac{y - y_1}{x - x_1}$

$-1 = \frac{y - 6}{x -0}$

$-1 = \frac{y - 6}{x}$

Multiply both sides by x

$-1 * x = \frac{y - 6}{x} * x$

$-x = y - 6$

Add x to both sides

$x -x = y - 6 + x$

$0 = y - 6 + x$

Reorder

$y + x- 6 = 0$

$Using \ m = \frac{y - y_2}{x - x_2}$

$-1 = \frac{y - 0}{x - 6}$

$-1 = \frac{y}{x - 6}$

Multiply both sides by x - 6

$-1 * (x-6) = \frac{y}{x - 6} * (x-6)$

$-1 * (x-6) = y$

$-x+6 = y$

Add x - 6 to both sided

$x - 6 -x+6 = y +x - 6$

$0 = y + x - 6$

$y + x - 6 = 0$

Hence, the equation of the line is $y + x - 6 = 0$

Jack and Susie want to save to buy a trampoline for their children. They each open a savings account that earns 1.5% a

olasank [31]

Answer:

$1,800(1.015)^{x}$

Step-by-step explanation:

we have

$f(x)=1,000(1.015)^{x}$

$g(x)=800(1.015)^{x}$

we know that

To find the function that represent the total amount Jack and Suzie will save in x years, adds f(x) and g(x)

so

$f(x)+g(x)=1,000(1.015)^{x}+800(1.015)^{x}$

$f(x)+g(x)=[1,000+800](1.015)^{x}$

$f(x)+g(x)=1,800(1.015)^{x}$

The length of a rectangle exceeds three times its width by 9 if the perimeter is 66 find the width of the rectangle?

morpeh [17]

Answer: 6
Step by step:
W is width, l is length, p is perimeter
The perimeter of a rectangle is 2w+2l.
l=3w+9
2l=6w+18
2l+2w=8w+18
P=8w+18
66=8w+18
48=8w
W=6
Hope this helps.
