Answer:
D. (3,-2)
Step-by-step explanation:
When we rotate a point 180 degrees about the origin, the rule is:
(x,y) -> (-x,-y)
So let's use this rule with our point.
(-3,2) -> (3,-2)
The answer is D (3,-2)
Answer:
512
Step-by-step explanation:
8 x 8 x 8 = 512
We know that we need to bake 6 pound for 138 minutes, then we have the proportion:
Let x be the time we need to bake the 3 pound roast, in this case we have the proportion:
By equating both ratios we have the proportion:
Now, by simplifying the right side of the proportion we have that:
For this proportion to be equal we need that x=69, therefore we need to cook the 3 pound roast for 69 minutes.
Answer:
The second number is four more than, two times the first number. The third ... Start by writing an expression for each of the three numbers. They are all formed from the first number, so let's call the first number x . Let the first number be x. The second number is 2x+4. The third number is 3x−5. We are told .
Step-by-step explanation:
First use the point slope form
y-y1=m(x-x1)
plug in the ordered pair to the y1 and x1 so
y--3=m(x--8)
add the slope and make the double minus into a plus
y+3=34(x+8)
then you can distribute the 34
y+3=34x+272
then to get it to slope intercept you subtract 3 from both sides of the equation to make it y=mx+b so
y=34x+269
