Answer:
x = 0 or x = 4
Step-by-step explanation:
x² + y² = 25 and y = -2x + 5
Here,
x² + y² = 25 ...(1)
Now,
Put the value of y = -2x + 5 in equation (1)
we get,
x² + (-2x + 5)² = 25
x² + {(-2x)² + 2(-2x) (5) + (5)²} = 25
x² + {4x² - 20x + 25} = 25
x² + 4x² - 20x + 25 = 25
5x² - 20x = 25 - 25
5x² - 20x = 0
5x(x - 4) = 0
5x = 0 or x - 4 = 0
x = 0/5 or x = 4
<em><u>x = 0 or x = 4</u></em>
Answer:
Below in bold.
Step-by-step explanation:
Ab = ut
Divide both sides by b
A = ut/b.
The other 2 are solved in a similar way:
Kc = 9a
c = 9a/K
Bd = Ca
d = Ca/B.
The area is 22 square units
Perimeter is how far around, so you are going to total the 2 lengths and 2 widths. A way to write that is P=2l+2w.
P = 2(5 5/8) + 2 (6 1/4)
2(5 5/8) = 10 10/8 or 11 2/8 or 11 1/4
2(6 1/4) = 12 1/2
P = 11 1/4 + 12 1/2
P = 23 3/4
Answer:
The slope is 3/4 and on a graph it would be 4 over to the right and 3 down.
