Answer:

By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)

Step-by-step explanation:

The formula for 90 degree clockwise rotation is

(x,y)--->(y,-x)

The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.

Hope this helps!

I'll leave the rest of the formulas I have in my notes for you!

180 degree rotations

(x,y)--->(-x,-y)

90 degree counterclockwise

(x,y)--->(-y,x)

270 degree rotation

(x,y)--->(y,-x)

Consider the rule y = 5x + 7.

maksim [4K]

Answer:

see below

Step-by-step explanation:

Consider the rule y = 5x + 7.

a. How many tiles are in Figure 0?

In figure 0, we let x=0

y = 5*0+7 = 0+7 = 7

b. Which figure has 37 tiles?

This means y = 37

37 = 5x+7

Subtract 7 from each side

37-7 = 5x+7-7

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

Figure 6 has 37 tiles

c. In the equation y = mx + b, what do the letters m and b represent?

m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0

Y-3=3(x+1)

babunello [35]

First, let's put that line in standard form
y - 3 = 3(x + 1)
y - 3 = 3x + 3
y = 3x + 6

(Standard form is y = mx+b, where m is slope and b is y-intercept.)

Now, a line parallel to that line would have the same slope of 3. So now we have m = 3. Plug that in for m and now we have
y = 3x + b

But we still need the b value. We can get that by plugging in the point (0, -3)
(-3) = 3(0) + b
-3 = 0 + b
b = -3

Now put b back into the equation and your final equation is
y = 3x - 3

What is the volume of this pyramid? How would I go about this?

konstantin123 [22]

The volume of a pyramid is:
$\frac{lwh}{3}$

You need the height for this. You are given the hypotenuse of a triangle, and the base of that triangle is half of 42 if you can see that. So, let's solve for the height using pythagorean theorem:
$35^2 = 21^2+h^2$

Solve for h:
$b = \sqrt{35^2-21^2} = 28$

Now you have all the information, let's just plug everything in:
$\frac{42*42*28}{3} = 597.33$

So, your volume is 597.33 cm³. Hope everything makes sense. hmy if something doesn't.
