Answer: the x intercept is -5 and the y intercept is 25.
Step-by-step explanation:
f(x) = -x^2 + 25
The x intercept is when y is zero and the y intercept is when x is zero.So input zero into the expression and solve for y.
-1(0)^2 + 25 = 25 so the y intercept is 25.
0=-x^2 +25
-25 -25
-25 = -x^2
x^2 = 25
x = -5 or 5
(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
Answer:
6:9
Step-by-step explanation:
the answer is 6:9 because 4:6' equivalent is 2:3, which is the same as 6:9
3/8 as a percentage is 37.5%
A unicycle has 1 wheel. u unicycles have u wheels.
A bicycle has 2 wheels. b bicycles have 2b wheels.
In u unicycles and b bicycles, there are a total of
u + 2b wheels.
We are told there are 28 wheels, so u + 2b must equal 28.
The answer is choice C. u + 2b = 28
