Answer:
<h2>x = -2, y = 1</h2>
Step-by-step explanation:
given the system of equations y=1/2x+2 and y=-2x+-3, since the 2 equations are functions of y, we will equate both equations together and calculate the value of x as shown
1/2x+2 = -2x-3
x/2+2x = -3-2
5x/2 = -5
5x = -10
x = -10/5
x = -2
Substituting x = -2 into any of the equation to get the value of y we have;
y = -2(-2)-3
y = 4-3
y = 1
The solution to the system of equation (x, y) = (-2, 1)
Answer:
180cm
Step-by-step explanation:
Vol of sphere = (4/3) pi r^3 and vol of cylinder = pi r^2 h
so
(4/3) pi 15^3 = pi (5)^2 h
(4/3) * 15^3 = 25h
h = [(4/3) * 15^3 ] / 25 = 180 cm
Answer:
B: 3/4
Step-by-step explanation:
Since we know this is an exponential function
y= ab^x
where a is the initial value and b is the growth rate or what we multiply by
For the first point x=1 and y = 3/2
3/2 = a b^1
3/2 = a*b
For the second point x=2 and y = 9/8
9/8 = a b^2
Take the second equation over the first
9/8 = a b^2
-------------------
3/2 = a*b
3/4 = b
The growth rate is 3/4
That would also be know as the rate of change
Answer:
parallel
Step-by-step explanation: It was hard to guess since it didn't show no shape.
Are you sure you said the whole problem cuz that is impossible to answer
