Answer:
Radius: 4
Center: (-5,4)
Step-by-step explanation:
To find the radius, you take the square root of what the equation is equal to (in this case that is 16)
To find the center, you set what is in the parenthesis equal to 0 so:
x+5=0 becomes x=-5
y-4=0 becomes y=4
Hope this helped!
Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P

and the length is 7/5 of that
Answer:
The equations that represent the situation are:
2y+x=5
5x-y=3
Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
