Describe two different methods you can use to graph the equation y=2x+4.

podryga [215]

One way is the 4 is the Y- intercept so you could graph that and the 2 is the slope so you would go up 2 units right 1 unit up 2 units right 1 unit ect.

Another method would be to plug in 0 for X and get the Y intercept then plug in 0 for Y and find the X intercept. graph the points and connect

$x=7.2\ units$

Step-by-step explanation:

we know that

In the right triangle of the figure

The tangent of angle of 67 degrees is equal to divide the opposite side to the angle of 67 degrees (17 units) by the adjacent side to angle of 67 degrees (x units)

$tan(67\°)=17/x$

Solve for x

$x=17/tan(67\°)$

$x=7.2\ units$

The original rectangle has a perimeter of 16

svet-max [94.6K]

12.4 / 6.2 = 2

so other side of enlarged rectangle = 1.8 x 2 = 3.6

Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32

Answer: 32 feet

------------------------

Another way to do:

12.4 / 6.2 = 2

SF = 2

The original rectangle has a perimeter of 16

Perimeter of the enlarged rectangle = 16 x 2 = 32

Marie 2,480 windows Marie washed 4 times as many windows as Elizabeth Elizabeth washed the same number of windows each day over

vlada-n [284]

Answer:

Elizabeth washes 99 windows each day.

Step-by-step explanation:

Given:

Total number of windows (N) = 2480

Marie washes windows = 4 times Elizabeth washes.

Elizabeth washes same number of windows for 5 days.

Let the number of windows washed by Elizabeth each day = 'x'.

Therefore, over the 5 days, the windows washed by Elizabeth = $5x$

Now, as per question:

Marie washes windows = 4 times Elizabeth washes.

So, number of windows washed by Marie = $4(5x)=20x$

Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth

So,

$2480=20x+5x\\\\2480=25x\\\\x=\frac{2480}{25}\approx99$

Therefore, Elizabeth washes 99 windows each day.
