Answer:
46. 10+10+6+6=32
47. 10×6=60
Step-by-step explanation:
46. the formula the perimeter is length plus width, is this case 10+6. but that would only be 2 sides so you have to times that by 2... (10+6)×2
47. area equals length times width so in this case 10×6=60
Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
55 = k.5 → k=55/5 ; k =11
The value of z when = 12 is : z= kx; z = 11(12) and z = 132
Answer:
The correct answer is b) x - y + 1 = 0
Step-by-step explanation:
In order to find this, start by finding the slope using the two points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 2)/(4 - 1)
m = 3/3
m = 1
Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
-x + y - 2 = -1
-x + y - 1 = 0
x - y + 1 = 0
(X+8)^2+(y-15)^2=289 would be the equation to the circle
Answer:
72 degrees
Step-by-step explanation:
2x+3x=180
5x=180
x=36
