We are given 2 points with there coordinates easy to calculate:

the upper one A(1,15) & the lower one B(6,10). Moreover the equation of this linear function is y = mx + b

1st) calculate m= (10-15) / (6-1) [FOMULA m=(y₂ - y₁) / (x₂ - x₁)]

m= -5/5 ==> m= - 1==> y=-x + b. To calculate b, replace x & y by any of the 2 points A, B. Say A(1,15)

15 = - (1) + b ==> b= 16 & final equation y = -x +16

The bricks are built to form a garden. The perimeter of the outer square is 264 centimeters. The area of the inner square is 900

zhenek [66]

Answer:

Length: 124.7875 cm

Width: 7.2125 cm

Step-by-step explanation:

The perimeter of this area can be calculated as:

P = 2L + 2W

Where P is the perimeter, L is the length and W is the width

If the perimeter is 264 centimeters, we have that:

2L + 2W = 264

L + W = 132

The area can be calculated as:

A = L*W

Where A is the area.

If the area is 900 cm2, we have that:

L*W = 900

From the first equation, we have that L = 132 - W

Using this value in the area equation, we have:

(132-W)*W = 900

132W - W2 = 900

W2 - 132W + 900 = 0

delta = b2 - 4ac = 17424 - 3600 = 13824

sqrt(delta) = 117.575

W1 = (132 + 117.575) / 2 = 124.7875 cm

W2 = (132 - 117.575) / 2 = 7.2125 cm

Using the smaller value for W, the length will be:

L + 7.2125 = 132

L = 124.7875 cm

Answer:

10.3 miles

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + 5^2 = c^2

81 + 25 = c^2

106 = c^2

the square root of 106 and c^2 is approximately c = 10.3

Graph the equation on the coordinate plane.<br><br><br><br> y = 4x+4

Alla [95]

To graph the equation of the line, find the x-intercept and the y-intercept of the function

we have

$y=4x+4$

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

Step 1

<u>Find the x-intercept</u>

For $y=0$

$0=4x+4$

$4x=-4$

$x=-1$

the x-intercept is the point $(-1,0)$

Step 2

<u>Find the y-intercept</u>

For $x=0$

$y=4*0+4$

$y=4$

the y-intercept is the point $(0,4)$

Step 3

Graph the points and draw the line

see the attached figure

therefore
