Answer:
By direct comparison we can see that m =2 (slope) and b =1 (intercept)
Step-by-step explanation:
Assuming the following function:
We want to find the following general equation for a linear model:
On this case we just need to add 2x on both sides of the original equation and we got:
By direct comparison we can see that m =2 and b =1
the value of m on this case represnt the slope and b the intercept.
The slope is defined by the following formula:
And is the interpretation is the rate of change of y respect to x, can be positive or negative. Or the increase/decrease of y when x increase 1 unit.
And the value b=1 represent the y intercept, that means if x=0 then y =1
Answer:
-3
Step-by-step explanation:
the complete question is<span>Point A has an x coordinate of −2 and lies in a circle with a center at (0, 0) and a radius of 5.
To the nearest tenth, what is the y-coordinate for point A?
A: 4.5
B: 4.6
C: 4.7
D: 4.8
see the attached figure
we know that
the equation of the circle is
(x-h)</span>²+(y-k)²=r²
(h,k) is the center---------> (h,k) is the point (0,0)
r=5 units
so
(x-h)²+(y-k)²=r²--------> (x-0)²+(y-0)²=5²------> x²+y²=25
substitute the value of x=-2 in the equation
(-2)²+y²=25------> y²=25-4------> y=(+/-)√21
the y coordinate of point A is positive----> see the picture
therefore
y=√21-----> 4.58-----> y=4.6
the answer isthe y-coordinate for point A is 4.6

An educated guess:)
Answer:
the perimeter is 64
Step-by-step explanation:
the length is 24 because 8*3 = 24 and since it is perimeter of a rectangle there are two sides that are the same length which is the length are 24+24 and width is 8+8 and all together
24+24+8+8=64
