Answer:

Take your pick, or make your own, there's an infinite number of ways.

Step-by-step explanation:

Rotate CCW 90° about (0, 0) (x, y) → (-y, x)

Shift 2 units right (x, y) → (x + 2, y)

or possibly the simplest

rotate CCW 90° about (1, 1) (x, y) → (xc - (y - yc) , yc + (x - xc)

where (xc, yc) = (1, 1) (x, y) → (1 - (y - 1) , 1 + (x - 1)

(x, y) → (2 - y , x)

A 40-foot tree casts a shadow 60 feet long. How long would the shadow of a 6-foot man be at that time?

Andre45 [30]

Answer:

26 ft

Step-by-step explanation:

I'm guessing this is how it's done

60-40= 20

there for at this time any shadow would be 20x it's original height/length

so 6+20=26 ft

lmk if I'm correct

If the units for x are years, and x = 5 represents the year 2015, what is the y-value for 2010?

Darya [45]

Given:

The given graph passes through the points (-3,4) and (3,2)

The x - axis represents the years. The value x = 5, year 2015.

We need to determine the y - value for 2010.

Slope:

The slope of the line can be determined using the formula,

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

Substituting the points (-3,2) and (3,2), we get;

$m=\frac{2-4}{3+3}$

$m=\frac{-1}{3}$

Thus, the slope of the line is $m=\frac{-1}{3}$

y - intercept:

The y - intercept in the graph is the point in the line that crosses the y - axis.

Thus, from the graph, it is obvious that the y - intercept is b = 3.

Equation of the line:

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting the values, we have;

$y=-\frac{1}{3}x+3$

Thus, the equation of the line is $y=-\frac{1}{3}x+3$

The y - value for 2010:

Since, it is given that x = 5 represents 2015 and 2010 is 5 years before 2010.

Hence, the value of x for 2010 is given by

$x=5-5=0$

Thus, x = 0 represents the year 2010.

To determine the y - value, let us substitute x = 0 in the equation $y=-\frac{1}{3}x+3$ , we have;

$y=-\frac{1}{3}(0)+3$

$y=3$

Thus, for 2010 the value of y is 3.

Seven less than 5 times a number is 62. What is the number. (Explain)

Marrrta [24]

7-5*14=62

The equation above is how you would write it with a variable.

The number is 14.

This is because if you do 14 times 5, the answer is 70. Then If you subtract from that, it would be 62.

You can also do 62+7, which is 70, and then divide that by 5 and you will still get 14.
