We need to construct the system of equations in order to solve that problem. Let's denote one-time membership fee with x and monthly fee with y. Then we can write that John paid x+6y=325 and Abigail paid x+9y=475. Solving the system of equations

, we find that x=25 and y=50. The monthly fee is 50 dollars.
Answer:
f(x)=-2x+9
f(4)+3=?
let x equal to 4
f(4)=-2(4)+8
f(4)=-8+9=+1
f(4)=1
then add 3 to f(4)
f(4)+3=1+3
f(4)+3=4
and he need f(4)+3 so the answer is
4
that's it
Answer:
a) the point is on the line
b) the lines are the same line
Step-by-step explanation:
a) The distance from a point to a line is zero when the point satisfies the equation of the line. That is, the point is on the line.
b) Two lines are zero distance apart when they are on top of each other, indistinguishable. That is, they are the same line.
Answer:
(0, 6), (2, 7)
y = mx + b
m = (7 - 6)/(2 - 0) = 1/2 = 0.5
b = 6
y = 1/2*x + 6
1/2*x - y = -6
So, answer D is correct. But m is the fraction 1/2 and not 12.
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
