Answer:

$x = 3$

Step-by-step explanation:

$1 0x -3 + 3 = 5 + 1 2 + 3$

$1 0 x = 5 + 1 5$

$1 0 x - 5x = 5 x + 1 5 - 5x$

$5x=15$

$\frac{5x}{5} = \frac{15}{5}$

$x = 3$

Find the equation of line (use exact numbers)

maw [93]

Answer:

$y=3x+3$

Step-by-step explanation:

Use the slope-intercept form:

$y=mx+b$

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( $\frac{rise}{run}$ ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

$y=mx+3$

Now find the slope. Use the slope formula:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}$

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

$(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3$

The slope is 3. Insert this value:

$y=3x+3$

The great Pyramid outside Cairo, Egypt, has a square base measuring 756 feet on a side and a height of 480ft

Vlada [557]

Answer:

V = 3,386,880 cubic yards

V = 91445760 cubic feet

V = (1/3) · b2 · h so 1/3 x 756^2 x 480 = 91445760 ft^3

Answer = 91445760 ft^3

Step-by-step explanation:

converting feet into yards

let

1 yard = 3 ft

1 ft = (1/3) yard

a = 756 ft = 756*(1/3) yards the length of the side of the square base

h = 480 ft = 480*(1/3) yards the height of the pyramid

a.) the volume of the pyramid V = (a^2*h)/3 = (a^2*h)(1/3)

V = (756*(1/3))^2*480*(1/3)*(1/3)

V = 3,386,880 cubic yards
