Answer:
The slope is -2
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= (-1 -3)/(-1 - -3)
= ( -1-3)/(-1+3)
= -4/2
= -2
The slope is -2
√16 = 4
3(4) = 12
---------------------------------------------
-2³ = -2(-2)(-2)
-2(-2) = 4
4(-2) = -8
--------------------------------------------
4(5 - 2²)
follow PEMDAS, first do the square
2² = 4
Next, do the subtraction
5 - 4 = 1
Finally, multiply
4(1) = 4
Combine all the terms together. Remember to bring down signs.
12 - (-8) + 4
12 - (-8) = 12 + 8 = 20
20 + 4 = 24
24 is your answer
hope this helps
Answer:
Infinite number of solutions
Step-by-step explanation:
Since the equations are both the same, we have an infinite number of solutions! The solutions lie on the graph y = -2x+5.
Answer:
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (-3,5).
Point on the circle is (x,y) = (1,8)
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (-3,5) and (x,y) = (1,8) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(1 - (-3))^2 + (8 - (5))^2 = r^2
(4)^2 + (3)^2 = r^2
16 + 9 = r^2
r^2 = 25
r = 5
